线切割，望文生义,通俗的讲,就是用一条线状的东西去切割物体。线切割，从专业上讲，泛指线切割机床，他是一种金属加工机床。有别与普通的金属切削机床，普通的机床基本上都会产生切削力，线切割是一种无切削力的机床，属于电火花放电加工机床。线切割的发明源于前苏联拉扎联科夫妇研究开关触点，受火花放电腐蚀损坏的现象，发现电火花的瞬时高温可以使局部的金属腐蚀，从而发明了电火花加工方法。传入我国，随着切割的电极丝--钼丝的发明，于是产生了快走丝线切割。由于电极丝的不同和成本路线不同，国外只有用铜丝加工的慢走丝线切割。最近十年，国人引入慢走丝修刀的原理，发明了中走丝线切割机床。线切割有通用的数控编程和加工系统，机床可以按照程序自动切割。但是被加工的工件必须是金属，是导电体。不过这几年，随着技术的成熟，采样跟踪的研究，像多晶硅和单晶硅的半导体等也能切割。以上文章来源于专注线切割18年的仁光数控技术人，（www.szrgcnc.com）企业原创，转载请注明出处。

用什么工具切割钢板好？ 10分 钢板切割工具种类 火焰切割 火焰切割设备的成本低并且是切割厚金属板唯一经济有效的手段，但是在薄板切割方面有其不足之处。与等离子比较起来，火焰切割的热影响区要大许多，热变形比较大。为了切割准确有效，操作人员需要拥有高超技术才能在切割过程中及时回避金属板的热变形。 耿 激光切割激光切割设备可切割4mm以下的不锈钢，在激光束中加氧气可切割20mm厚的碳钢，但加氧切割后会在切割面形成薄薄的氧化膜。切割的最大厚度可增加到20mm，但切割部件的尺寸误差较大。　激光切割设备的价格相当贵，约150万元以上。 线切割 电火花线切割简称线切割。它是在电火花穿孔、成形加工的基础上发展起来的。它不仅使电火花加工的应用得到了发展，而且某些方面已取代了电火花穿孔、成形加工。如今，线切割机床已占电火花机床的大半。 剪板机 剪板机是借于运动的上刀片和固定的下刀片，采用合理的刀片间隙，对各种厚度的金属板材施加剪切力，使板材按所需要的尺寸断裂分离。剪板机属于锻压机械中的一种，主要作用就是金属加工行业。 等离子切割机 等离子切割是利用高温等离子电弧的热量使工件切口处的金属部分或局部熔化（和蒸发），并借高速等离子的动量排除熔融金属以形成切口的一种加工方法。 超高压水切割 超高压水切割又称水刀和水射流，它是将普通的水经过多级增压后所产生的高能量（380MPa）水流，再通过一个极细的红宝石喷嘴（Φ0.1-0.35mm），以每秒近千米的速度喷射切割，这种切割方式称为超高压水切割。 一般用来切割金属材料的工具里什么比较好 板材金属，可以用剪板机裁剪下料，裁板机属于冷加工，精度比较好。 其次是激光等离子切割机， 依次是水刀切割 然后是精细等离子切割机， 最次是氧乙炔等火焰切割。 型材首先考虑金属带锯床， 然后圆盘式金属带锯，树脂砂轮式切割机次之（切割有毛刺）， 最次使用角磨机，安装切割片砂轮切割。 切割金属材料用什么切割机好 看你切割什么金属材料，如果是厚板的话，你可以火焰切割机，因为火焰切割机可以切割6--200mm的，还有切割的是一般的金属材料的话，可以使用等离子切割机的，它可以切割0.8--25mm，等离子切割机是根据电源的大小来决定的，电源越大切割的厚度就越厚，还有激光切割机一般都是切割薄片金属材料的，500W激光切割机可以切割的厚度是0.3--6mm，激光切割机的功率大小来定的，功率越大切割的厚度就越厚，在切割机行业中真的有太多切割机厂家了，真心不知道哪一件是最好，不过我听说广州仙锯还不错，个人意见。 切割钢板的方法有哪些 必须要知道是多厚的板. 你在割多大的圆,冷冲压行不行,也有一种叫打孔器的手动工具,不工孔不能太大. 不知道你的数量大不大,如果量很大,可以考虑开发专用的锯床来进行加工,照你所说,只有锯割符合要求. 如果只是一两个,可以用手工来锯. 如果不在乎设备造价的话,可以采用台湾型的立式带锯床来进行改造,用压缩空气进行冷却排屑,大型立柱加上直臂,把锯床安装在直臂上,可以进行远程控制. 照你所说,我猜想可能是用于海上钻井平台,不知是否正确,我在深圳,如果需要,可以谈谈. 用什么切割不锈钢 您好！ 视螺旋输送器（绞龙）大小，常用的主要有两种拆卸切割办法： 一种是角磨机安装切割片，切掉叶片与绞龙轴的焊接点，优点是工具易获得，缺点是小角度的地方可能会切不到； 角磨机图 另一种是用等离子切割，需要等离子切割机、压缩空气源等，主要优点是工效高，割枪枪头可以伸进较小的地方。 等离子切割机图（还需要压缩空气气源） 不锈钢用什么工具切割多少钱 型材切割机500元或圆锯机3000元左右。 请问金属切割，一般用什么设备切割效率高，节省成本呢 切割金属可以使用co2金属切割机，光纤机，如果要按切割效率和综合成本来说，建议光纤切割机，森峰激光给你对比一下，同样使用三年，20万左右的激光切割机与50万左右的光纤激光切割机在使用成本（注：使用成本=购机成本+消耗成本+维护成本）将画上等号！也就是说同样使用三年，CO2激光切割机成本投入将超越光纤。同时光纤激光切割机良好的加工优势也将给厂家在加工工艺上提高竞争力。光纤激光切割机虽然价格昂贵，但是同样可以创造出更多的价值，建议你&去森峰、镭鸣这样的厂家去考察考察 不锈钢板需要用什么工具切断？ 等离子切割机 裁板机 这是我们最常用的工具哦 金属切割方法有多少种？ 电火花线切割机（Wire cut Electrical Discharge Machining简称WEDM），属电加工范畴，是由前苏联拉扎林科夫妇研究开关触点受火花放电腐蚀损坏的现象和原因时，发现电火花的瞬时高温可以使局部的金属熔化、氧化而被腐蚀掉，从而开创和发明了电火花加工方法。线切割机也于1960年发明于前苏联，我国是第一个用于工业生产的国家。其基本物理原理是自由正离子和电子在场中积累，很快形成一个被电离的导电通道。在这个阶段，两板间形成电流。导致粒子间发生无数次碰撞，形成一个等离子区，并很快升高到8000到12000度的高温，在两导体表面瞬间熔化一些材料，同时，由于电极和电介液的汽化，形成一个气泡，并且它的压力规则上升直到非常高。然后电流中断，温度突然降低，引起气泡内向爆炸，产生的动力把溶化的物质抛出弹坑，然后被腐蚀的材料在电介液中重新凝结成小的球体，并被电介液排走。然后通过NC控制的监测和管控，伺服机构执行，使这种放电现象均匀一致，从而达到加工物被加工，使之成为合乎要求之尺寸大小及形状精度的产品。电火花线切割机按走丝速度可分为高速往复走丝电火花线切割机（Reciprocating type High Speed Wire cut Electrical Di穿charge Machining俗称“快走丝”）、低速单向走丝电火花线切割机（Low Speed one-way walk Wire cut Electrical Discharge Machining俗称“慢走丝”）和立式自旋转电火花线切割机（Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire）三类。又可按工作台形式分成单立柱十字工作台型和双立柱型（俗称龙门型）。 往复走丝电火花线切割机床的走丝速度为6～12 m/s，是我国独创的机种。自1970年9月由第三机械工业部所属国营长风机械总厂研制成功“数字程序自动控制线切割机床”，为该类机床国内首创。1972年第三机械工业部对工厂生产的CKX数控线切割机床进行技术鉴定，认为已经达到当时国内先进水平。1973年按照第三机械工业部的决定，编号为CKX — 1的数控线切割机床开始投入批量生产。1981年9月成功研制出具有锥度切割功能的DK3220型的座标数控机，产品的最大特点是具有1.5度锥度切割功能。完成了线切割机床的重大技术改进。随着大锥度切割技术逐步完善，变锥度、上下异形的切割加工也取得了很大的进步。大厚度切割技术的突破，横剖面及纵剖面精度有了较大提高，加工厚度可超过1000mm以上。使往复走丝线切割机床更具有一定的优势。同时满足了国内外客户的需求。这类机床的数量正以较快的速度增长，由原来年产量2~3千台上升到年产量数万台，目前全国往复走丝线切割机床的存量已达20余万台，应用于各类中低档模具制造和特殊零件加工，成为我国数控机床中应用最广泛的机种之一。但由于往复走丝线切割机床不能对电极丝实施恒张力控制，故电极丝抖动大，在加工过程中易断丝。由于电级丝是往复使用，所以会造成电极丝损耗，加工精度和表面质量降低。 低速走丝线切割机电极丝以铜线作为工具电极，一般以低于0.2m/s的速度作单向运动，在铜线与铜、钢或超硬合金等被加工物材料之间施加60~300V的脉冲电压，并保持5~50um间隙，间隙中充满脱离子水(接近蒸馏水)等绝缘介质，使电极与被加工物之间发生火花放电，并彼此被消耗、腐蚀，在工件表面上电......>>

火花机放电加工

放电加工在现代模具制造业中，与磨床．铣床．车床．线切割等具有同等位置，且是不可或缺的一个工序。它的工作原理是原 苏联人发明的。它的历史可追塑到上个世纪六十年代，类型可分为二极管和三极管式两种。在此我们介绍一下放电的加工原理：如果从宏观说明的话：放电的加工原理是通过无限靠近但不接触的正负带电体（即电极与工件），在绝缘液（火花油）作用下，将电能转变成热能的过程（瞬间10000度左右），从而达到腐蚀加工物成型的目的。如果从微观说明的话：放电的加工原理是通过机械控制使带负的电极，无限靠近，但不接触带正电的工件时，产生强大电场。从而产生电子流，冲击绝缘液微粒的外围电子，使其电子数目以金字塔的形式大量增加，然后以极高的加速度与速度轰击工件表面的原子微粒，使其产生高温后在爆破力的作用下脱落。当然，电极的原子微粒也会受到正离子的轰击从而产生高温后在爆破力的作用下脱落。同时，在此过程中产生一定数量的正负离子和大量的中性微粒。然后，部分正离子移至电极一边，且吸附于电极表面，使其损耗得补偿。部分负离子则移至工件一边，且吸附于工件表面。最后当下一波的休止脉冲奏效时，一切脱落物将随绝缘液冲走。实践中，我们使用不同的条件时，有不同的粗糙度，速度，损耗，火花位。原因是在上述的过程中，在时间上各种变化是否同步达到最好的配合。当然还有与电极和工件材质的导热性.熔点.密度等物理特性及介质有很大关系。总而言之，放电加工是一项精密加工，作为技术人员，我们一定要知道它的放电加工原理。希望各位多加努力，多加探索与发现。相信各位一定能够超越自我，把握明天！

　　随着个人的文明素养不断提升，感谢信使用的频率越来越高，我们时常通过写感谢信来表达感恩。如何写出一个充满真情实感的感谢信？以下是我整理的英文感谢信7篇，希望对大家有所帮助。 英文感谢信 篇1 　　尊敬的人事部Lisa: 　　Lisa，您好!在此冒昧占用您几分钟。 我是武娜，来自XX外语外贸大学，14号上午8:50参加了贵公司的Group Assessment，我想面试者众多，您可能忘了我是谁了，呵呵，不知您有没有印象，那场有位面试者老蹲地上捡胸前名字纸牌。 　　首先，我很感谢贵公司给我这次Group Assessment的机会，这是我人生第一次Group Assessment，让我有机会亲身感受德勤office的工作氛围和气氛，让我真正体念到了团队合作的重要性和技巧性，让我有机会结交新的7位朋友，让我有机会总结自己Group Assessment的不足和优点，让我对团队工作方式有了更加正确的认识。 同时，我也想借此机会向贵公司提点意见，从我贴胸牌的那一刻起，胸牌就不断地掉，我想是不是我太紧张连我的胸前纸牌也受不了拼着命想溜啊，讨论过程中我不断地压着它，它还是趁机逃跑了好多次，为了把它抓回来，我连掉在地上的铅笔也忘了捡，最后还是我们的manager捡起来的。回到学校后，我又试了下别的粘性物质，发现我的衣服根本粘不住，在此我能否建议贵公司能否将粘性纸牌换成其他形式，比如立体纸牌摆在会议桌上，这样队友更能清楚地看到互相的名字。以防1%的可能出现我这种情况。您觉得呢? 再次感谢贵公司给我Group Assessment 的机会，让我终生难忘，希望有机会跟您进行更深的交流! 　　此致 敬礼 　　武娜 　　20xx年xx月15日 　　Dear Lisa: 　　To begin with， please allow me to thank your company of giving me the opportunity for Group Assessment。 Honestly speaking， this was the first group assessment in my life。 Im very pleasured that I have the opportunity to experience the working place and atmosphere of DTT， the opportunity to make new friends with my 7 teammates， the opportunity to learn the importance of teamwork skills， the opportunity to review my weak points and strong points and enhance my understanding of teamwork ， all of which I appreciate very much Meanwhile， would you mind that I make a suggestion here， from the moment I stuck the name card on my chest， it began to drop onto the floor， I wonder maybe I was too nervous that even this lovely name card could not stand it， when I got back to my dorm， I tested with other sticky things， It was found that my coat material refused to stick anything， so would you mind my suggestion to replace sticky name card with other ways in case for the 1% possibility of my case， for example， maybe we can use a name card displayed on the roundtable， and also it is more convenient for the teammates to know each other。 How do you think? Thanks again for the chance your company given me to participate this Group Assessment， which I will keep in my mind throughout my life。 I hope we can have an opportunity for further communications。 　　Best wishes to you and Deloitte sincerely 　　Yours sincere 　　Wuna 　　20xx-xx-15 英文感谢信 篇2 　　尊敬的俊豪客户：您好！ 　　值此20xx新春来临之际，怀着感恩的心情，我仅代表俊豪公司全体同仁向您及家人表示最诚挚的新春祝福和最衷心的感谢，感谢您一直以来对俊豪公司的信任和支持。 　　八年风雨征程，见证着俊豪公司的成长、进步与发展。如今的俊豪公司，已经发展成为集原材料的配送、生产、加工、研发、营销推广于一体的中国包装行业的重要企业，她以无可争议的经营实力和品牌价值，稳居中国包装行业百强之列。俊豪人，永怀感恩之心！我们感恩社会，是社会给了我们生存发展的机会和环境；感恩客户，是你们选择了俊豪，是你们用智慧帮助我们开拓了市场，为我们提供订单；是你们及时的反馈市场信息，使得俊豪产品在升级换代过程中成功赢得了市场。 　　饮水思源，我们深知，俊豪公司的发展和壮大，一刻也离不开您的关注、信任、支持和参与。能与尊敬的各位客户结成合作伙伴，实现互利共赢、共同发展，我们感到荣幸之至。今后我们将不断开拓进取，凭借优质的产品、良好的信誉和周到的.服务，为广大客户朋友提供更为广阔的发展空间。我们完全相信，只要有您的支持合作，只要我们不断努力，我们共同的事业一定会有大空间、大作为、大发展。 　　跑销售其实是一件很辛苦的事，风吹雨打、酸甜苦辣都要经历；不过也是很快乐的，自从进入这个行业以来，让我的内心开始变得更加宽广和融洽，坚强与进取。每每心灵受挫、遭受打击时，一想到众多客户的支持和信赖，看到家人认可的目光和眼神，我就不敢让自己懈怠，而继续勇敢地在这个行业中前行。 　　在过去的日子里，我不知道您是否烦过我向您介绍产品，是否对我的服务感到满意，但我从内心深处都希望您拥有快乐，快乐——源于你心，如果你不是真正快乐，你不可能让别人快乐，别人肯定会感觉到你心中是否快乐。让客户快乐，就是让他对产品产生值得拥有的快感，和真正拥有产品后的快乐。这是其他工作无法所能做到的。所以我不止一次地告诫自己，决不要因为情面而不向人销售快乐，也决不要轻易对这个行业说“不”，我要在这个行业中坚定地走下去并给更多的人送去满意的服务！是你们对我的支持、热情、信赖，给了我前进的信心和勇气；感恩支持、帮助过我的朋友们，是你们的信任与关爱引领着我走向一个又一个的辉煌!因为我知道：“只有有了您们的支持与帮助，才有了我的存在；而只因有了我，也才有了这份来之不易的工作。从这个意义上讲，广大客户就是我的?衣食父母? 　　由衷地希望在20xx年我和您一起志存高远、追求卓越！期待着与您更加紧密地合作，携手共创包装事业新天地！愿您能在未来的日子里，继续给我更多的支持和帮助，助我在这个行业中 　　快速成长！再次感谢您的信任和合作，恭祝您身体健康！阖家幸福！事业兴旺！ 英文感谢信 篇3 　　 kamenori foundation thank-you note dear kamenori, 　　i"m very grateful for giving me thisopportunity to kamenori foundation, this is kamenori foundation to give me ascholarship, i can be a chinaand japanexchange student. i am very happy, because my first visit to japan, this is a exchange students i can furtherunderstand japan.perhaps, i still can become friendly relations between china and japan"s representative. because japan is i amlonging for the country. 　　now, i will go to japan. i heard that japan has a lotof food, such as japanese ramen, sushi, great kanto cook, tuna and many otherfood. of course the japanese kimono is also very beautiful, japanese cherryblossom and mount fuji, this beautiful scenerylet us linger. this time i as an exchange student i can not only learn aboutjapanese culture, school, living habits, i also want to know that i"m moreinterested in japanese anime. i think the japanese anime is not only shows thejapanese culture, but also shows that the japanese unique imagination, such asa block, naruto etc excellent cartoon, not only in the world popular, andjapanese culture of the world, this is very unique. 　　i hope i go to japan, i will have a very deep memory, there wasa lot of friends, learn about japanese culture, become china and japanthe friendly relations between the witnesses. then i get a scholarship, i ammore sure i will be very good in japan, the japanese family getalong well. 　　so, iam very grateful to the kamenori foundation to give me a scholarship andopportunity, so that i can be in japan to learn more, learn more,make more friends, and at the same time, this to my future plan has a betterfoundation. 　　congratulations 　　afs program students. 英文感谢信 篇4 Dear Mother 　　Thank you for always supporting me without any conditions.

Everything is new and interesting! I made some friends on the trip over and they have been very kind and helpful. Still you know how much I miss you and your cooking? My mouth waters at the mere thought of those delectable Chinese dishes you prepare. Last night my friends invited me to dinner. They had some strange ways of describing their hunger. For instance there was“I"m starving to death”“I"m famished” and“I"m so hungry I could eat a horse” which has a similar expression in Chinese; I"m sure you know the one. How about“I"m making a pig of myself”! A little confusing hmm? Anyway this stuff may be useful to you 　　as an English teacher so I"m also sending a tape.

Last month it was the first time that I traveled to Beijing for business, signing a contract with a Chinese food company. Unfortunately I got a bad flu and then had a fever. I was sent to your hoital. Because my temperature was nearly 40 degree centigrade, I was asked to be in hoital. I worried about my business and the delay of signing the contact would lead to great losses to my company. However, After the doctors" careful treatment and nurses" patient care, I was recovered only in 4 days. 　　I completed the negotiation with the food company smoothly and signed the contract on time finally. So I sincerely appreciate all the staffs in your hoital who helped me full-heatedly. I was deeply impressed by the kind doctors and nurses, the pleasant and comfortable environment, and considerate services. I have no relatives and friends in Beijing, but I felt at home in your hoital. I will always remember all those warmhearted persons and your hoital in my heart. 　　Best wishes to you all! 　　Faithfully yours,

I regret to say that, at this stage ,such an arrangement would be rather premature. We would, however, be willing to engage in a trial collaboration with you company to see how the arrangement works.

On a personal note, I must say that I am delighted that we are probably going to strengthen our relationship. I have very pleasant memories of my last visit to Bahrain when you entertained me so delightfully .I look forward to reciprocating on your next visit to Milan . My very best wishes to you and your wife. 4月12日建议担任为公室器具之独家代理来信已经收悉。过去双方合作皆互利互助，能获您的眷顾作我公司于巴林的独家代理，殊感荣幸。据知您公司两服务技师曾到我公司米兰工厂受训。相信您公司在取得代理权后，仍会继续注重合格售后服务人员的训练。现随信附上协议草稿，请查实各项条款，惠复是盼。能加强业务，我亦感到欣喜，前次到访巴林，蒙盛情款待，不胜感激。祈盼您莅临米兰时，容我一尽地主之谊。此致敬礼

电火花加工是利用浸在工作液中的两极间脉冲放电时产生的电蚀作用蚀除导电材料的特种加工方法，又称放电加工或电蚀加工，英文简称EDM。 1943年，苏联学者拉扎连科夫妇研究发明电火花加工，之后随着脉冲电源和控制系统的改进，而迅速发展起来。最初使用的脉冲电源是简单的电阻-电容回路。50年代初，改进为电阻-电感-电容等回路。同时，还采用脉冲发电机之类的所谓长脉冲电源，使蚀除效率提高，工具电极相对损耗降低。 随后又出现了大功率电子管、闸流管等高频脉冲电源，使在同样表面粗糙度条件下的生产率得以提高。60年代中期，出现了晶体管和可控硅脉冲电源，提高了能源利用效率和降低了工具电极损耗，并扩大了粗精加工的可调范围。 到70年代，出现了高低压复合脉冲、多回路脉冲、等幅脉冲和可调波形脉冲等电源，在加工表面粗糙度、加工精度和降低工具电极损耗等方面又有了新的进展。在控制系统方面，从最初简单地保持放电间隙，控制工具电极的进退，逐步发展到利用微型计算机，对电参数和非电参数等各种因素进行适时控制。 进行电火花加工时，工具电极和工件分别接脉冲电源的两极，并浸入工作液中，或将工作液充入放电间隙。通过间隙自动控制系统控制工具电极向工件进给，当两电极间的间隙达到一定距离时，两电极上施加的脉冲电压将工作液击穿，产生火花放电。 在放电的微细通道中瞬时集中大量的热能，温度可高达一万摄氏度以上，压力也有急剧变化，从而使这一点工作表面局部微量的金属材料立刻熔化、气化，并爆炸式地飞溅到工作液中，迅速冷凝，形成固体的金属微粒，被工作液带走。这时在工件表面上便留下一个微小的凹坑痕迹，放电短暂停歇，两电极间工作液恢复绝缘状态。 紧接着，下一个脉冲电压又在两电极相对接近的另一点处击穿，产生火花放电，重复上述过程。这样，虽然每个脉冲放电蚀除的金属量极少，但因每秒有成千上万次脉冲放电作用，就能蚀除较多的金属，具有一定的生产率。 在保持工具电极与工件之间恒定放电间隙的条件下，一边蚀除工件金属，一边使工具电极不断地向工件进给，最后便加工出与工具电极形状相对应的形状来。因此，只要改变工具电极的形状和工具电极与工件之间的相对运动方式，就能加工出各种复杂的型面。 工具电极常用导电性良好、熔点较高、易加工的耐电蚀材料，如铜、石墨、铜钨合金和钼等。在加工过程中，工具电极也有损耗，但小于工件金属的蚀除量，甚至接近于无损耗。 工作液作为放电介质，在加工过程中还起着冷却、排屑等作用。常用的工作液是粘度较低、闪点较高、性能稳定的介质，如煤油、去离子水和乳化液等。 按照工具电极的形式及其与工件之间相对运动的特征，可将电火花加工方式分为五类：利用成型工具电极，相对工件作简单进给运动的电火花成形加工；利用轴向移动的金属丝作工具电极，工件按所需形状和尺寸作轨迹运动，以切割导电材料的电火花线切割加工；利用金属丝或成形导电磨轮作工具电极，进行小孔磨削或成形磨削的电火花磨削；用于加工螺纹环规、螺纹塞规、齿轮等的电火花共轭回转加工；小孔加工、刻印、表面合金化、表面强化等其他种类的加工。 电火花加工能加工普通切削加工方法难以切削的材料和复杂形状工件；加工时无切削力；不产生毛刺和刀痕沟纹等缺陷；工具电极材料无须比工件材料硬；直接使用电能加工，便于实现自动化；加工后表面产生变质层，在某些应用中须进一步去除；工作液的净化和加工中产生的烟雾污染处理比较麻烦。 电火花加工的主要用于加工具有复杂形状的型孔和型腔的模具和零件；加工各种硬、脆材料，如硬质合金和淬火钢等；加工深细孔、异形孔、深槽、窄缝和切割薄片等；加工各种成形刀具、样板和螺纹环规等工具和量具。

A few days ago, I was taken to the hospital because of drug allergy, and I got the help and care of everyone at my most difficult time. Whether that day take me to the hospital, or have been waiting for the students in the bedroom, or a telephone message sent condolences to the students, and has been on the phone in front of the pan, please let me with the most grateful heart sincerely to you say "thank you, I"m glad to meet you in my life, and lucky to get everybody"s care, thank you... "Of course, the experienced teacher pan helped me to feel the wisdom of an elderly person and made me feel at ease. 　　That day. I"m allergic to cephalosporins, symptoms and ferocious, successively appeared in just a few minutes abdominal cramps, whole body red and hot the whole body twitching, and breathing difficulties, completely can"t move, can only tell Jenny to call a person. In the moment when I was most uncomfortable and almost unconscious, I heard people gathering in my dormitory to give me the first immediate concern. Heard Jenny went out to call people around make a phone call and connection to my father, at the first time heard jingjing anxiously outside contact pan, hear Zheng Qian and LuoLiPing rushed to ask specific situation, hear sweet, Zhong Xiaosu to discuss with you, hear Jiang Shihui, Ceng Hailin, Zhou Guang they come, hear they say the ambulance coming... I heard a lot of sounds, it was messy but it was reassuring. Especially to hear the boys in our class, I feel more than hear the ambulance coming call people"s mind, they will I from carrying on the fourth floor to the first floor, carry on the ambulance, the stairs is shaking, but they look very stable. Wait for the ambulance, though I have almost lost consciousness, can"t hear any sound, but I feel there are several hands has been patting me, told me that will be fine, don"t be nervous. When we arrived at the hospital, we were sent to the emergency room for registration, for examination, after a busy day, and later, because of the poor service attitude of the doctors, the people were almost quarreling with the doctor. Finally you and me together back to the bedroom, the car, they also continued to pan and dormitory students news peace, such as my father to pick me up, at that time was already very late, see Zheng Qian down when I opened the door for us in the mind feel warm appreciation. When I come back the next day rehabilitation, Jenny and ching-ching told me that when they go back to that day, many dormitory all didn"t sleep, waiting for news, the second day many people who are late learned of the news to ask me. I was really touched by this, and I felt how lucky I was. I was lucky to meet you, and I got so much help in the most difficult time. 　　Please let me express my deep gratitude to you again with my sincerest heart. I have received a lot of attention from you. I have seen it. I have seen it. I remember it. Thank you, thank you very much. 　　advance 　　Salute! 英文感谢信 篇2 Dear Mom and Dad, 　　Although we can only keep in touch with each other by the telephone or the Internet, I wish I could let you know how much I love you and how much I"ve appreciated the things you"ve done for me. It is never too much to say thank you to you, my dear parents. 　　First and the most important is that thank you for bringing me to this world. During the 20 years, you have done a lot for me, but I haven"t realized how much I love you until I left home to the university. I understand how much effort you have cost to bring me up. Now, I have grown up, I can look after you. 　　Second, I want to thank you that you give me a good environment to grow up. There is an old saying “Parents are the first teacher to their children”. In my life, you are the typical ones. Because of your good examples I formed the good habit of learning at an early age which benefits my life. 　　At last, I want to say “thank you” is that you always support my choice. You never forced me to do anything I was not interested in. You told me to pursuit my own dreams without hesitation and you would support me forever. You also told me to how to be a human. Now I become an optimistic and cheerful girl and I feel happy every day. 　　I really miss you when I am writing this thank you letter. I can"t wait to go home to share more time together with you.You are my most important people in the world and I will love you forever. 　　Yours, XXX 英文感谢信 篇3 　　XXX： 　　Thank you very much for my birthday. I am very happy! This is the happiest in my life the first birthday. You are really a good friend of mine. I would also like your next birthday. I hope by that time, we can hurt our hearts Play fast. And can be delicious to eat. Birthday in the day, we all share faster! In short, I am very happy to play. 　　Thank you for my birthday. Today is an unforgettable day for me!

It made me feel so warm inside. My health has improved a lot with your care and comfort. 　　I had also fallen behind on my sutdies because of the sickness, that"s why you came over every weekend to help me catch up. Hence I had quickly made up all that has fallen behind. For that I am also very grateful. 英文感谢信 篇7 Dear Mr. Zhu, 　　A: hello! 　　For the past year, you have always tried your best to give us knowledge and letters of thanks to your teachers. In the evening, even the stars and moon are peacefully in dreamland, but the light of your home is still on. Every morning, you get up earlier than me. 　　I am weak and sickly. For this reason, academic performance can not be matched. In addition to the free spread of the habit, the study also did not pay attention to, all aspects of the casual, not strict requirements for themselves. After I was promoted to third grade, I entered your class, and you saw my shortcomings. I patiently sought to talk to me again and again, which made me realize my shortcomings. So I made a serious correction. First of all, you ask me to practice good words, to write the word straight forward. I couldn"t read my own handwriting before. Under your guidance, I worked hard and finally got the word straight. You have written a+ on my homework to encourage me. Do you know? This small a+ gives me infinite strength, which gives me confidence a hundredfold, which also makes me more and more interested in learning, thank-you letter "letter to the teacher". 　　My composition is also very poor, often write a few words even finished. When you find out, you always give me a good explanation, teach me how to write the composition well. My writing level has improved once more. Now, my composition every time is hanged in the back of the classroom to let the students learn, I in the heart is how happy! Teacher, every bit of my progress, I can"t live without you to my education. 　　Teacher, thank you for my efforts, I will not live up to your expectations of me, grow up to be the useful material of the motherland. 　　I wish you good work, good health and good health. 英文感谢信 篇8 　　date and place 　　mr。____ 　　minister of _____ 　　(address) 　　beijing，china 　　dear minister， 　　i am writing this letter to thank you for you warm hospitality accorded to me and my delegation during our recent visit to your beautiful country。 i would also like to thank you for your interesting discussion with me which i have found very informative and useful。 　　during the entire visit， my delegation and i were overwhelmed by the enthusiasm expressed by your business representatives on cooperation with china。 i sincerely hope we could have more exchanges like this one when we would be able to continue our interesting discussion on possible ways to expand our bilateral ecomomic and trade relations and bring our business people together。 　　i am lookingforward to your early visit to china when i will be able to pay back some of the hospitality i received during my memorable stay in yur beautiful country。 with kind personal regards， 　　faithfully yours， 　　(signed) 　　mr。___ minister of economic cooperation 　　place 英文感谢信 篇9 　　Dear XX, 　　I will be very grateful if you can take several minutes to finish reading this email. 　　I have been working in XXXX for over XXX year since XXXX. I feel very thankful to you and HR of offering me this job. At the very beginning, I haven"t graduated. Because my major is not related to the job, I am lack of the basic knowledge of XXXXXX. As a result, I bought a book which can help me have some basic understanding of my job. Furthermore, I also finished reading the two books which XXX lent me. They are very helpful to me and I can deal much more things recently on my own due to all the efforts I put into my study. 　　The charm of this job is that it is full of challenges; Nevertheless, I can always find some good solutions to solve the problems on my own or with the help of some more experienced colleagues. 　　I love this job, I put my energy into it, I am diligent, meticulous, and easy-going. I got along with different people including my colleagues and guys from different companies. Additionally, I rarely make mistakes during the work. Last year, I was assigned to the finance department to give them a hand. The major job was to input the transactions of RMB and USD. During the process, I always double checked the transactions to make sure all the account numbers are correct. This small example proves that I am a trustworthy and meticulous employee. 　　Nowadays, the price in XXXX is higher than other cities in China. The high rent and transportation fees really give me a lot of pressure. To tell the truth, the current salary is not enough for my daily life. Sometimes I have to ask my parents for some extra money. 　　Owing to the reasons which I have listed above, I sincerely hope you can consider raising my salary to XXXXX per month, I would be very glad if you approve my proposition.

线切割一般指电火花线切割电火花线切割机（Wire Electrical Discharge Machining简称WEDM），属电加工范畴，是由前苏联拉扎联科夫妇研究开关触点受火花放电腐蚀损坏的现象和原因时，发现电火花的瞬时高温可以使局部的金属熔化、氧化而被腐蚀掉，从而开创和发明了电火花加工方法。线切割机也于1960年发明于前苏联，我国是第一个用于工业生产的国家。电火花线切割机按走丝速度可分为高速往复走丝电火花线切割机（Reciprocating type High Speed Wire cut Electrical Discharge Machining俗称“快走丝”）、低速单向走丝电火花线切割机（Low Speed one-way walk Wire cut Electrical Discharge Machining俗称“慢走丝”）和立式自旋转电火花线切割机（Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire）三类。又可按工作台形式分成单立柱十字工作台型和双立柱型（俗称龙门型）。往复走丝电火花线切割机床往复走丝电火花线切割机订的走丝速度为6～12 m/s，是我国独创的机种。自1970年9月由第三机械工业部所属国营长风机械总厂研制成功“数字程序自动控制线切割机床”，为该类机床国内首创。1972年第三机械工业部对工厂生产的CKX数控线切割机床进行技术鉴定，认为已经达到当时国内先进水平。1973年按照第三机械工业部的决定，编号为CKX — 1的数控线切割机床开始投入批量生产。1981年9月成功研制出具有锥度切割功能的DK3220型的坐标数控机，产品的最大特点是具有1.5度锥度切割功能。完成了线切割机床的重大技术改进。随着大锥度切割技术逐步完善，变锥度、上下异形的切割加工也取得了很大的进步。大厚度切割技术的突破，横剖面及纵剖面精度有了较大提高，加工厚度可超过1000mm以上。使往复走丝线切割机床更具有一定的优势。同时满足了国内外客户的需求。这类机床的数量正以较快的速度增长，由原来年产量2~3千台上升到年产量数万台，目前全国往复走丝线切割机床的存量已达20余万台，应用于各类中低档模具制造和特殊零件加工，成为我国数控机床中应用最广泛的机种之一。但由于往复走丝线切割机床不能对电极丝实施恒张力控制，故电极丝抖动大，在加工过程中易断丝。由于电级丝是往复使用，所以会造成电极丝损耗，加工精度和表面质量降低。低速单向走丝电火花线切割机低速走丝线切割机电极丝以铜线作为工具电极，一般以低于0.2m/s的速度作单向运动，在铜线与铜、钢或超硬合金等被加工物材料之间施加60~300V的脉冲电压，并保持5~50um间隙，间隙中充满脱离子水(接近蒸馏水)等绝缘介质，使电极与被加工物之间发生火花放电，并彼此被消耗、腐蚀，在工件表面上电蚀出无数的小坑，通过NC控制的监测和管控，伺服机构执行，使这种放电现象均匀一致，从而达到加工物被加工，使之成为合乎要求之尺寸大小及形状精度的产品。目前精度可达0.001mm级，表面质量也接近磨削水平。电极丝放电后不再使用，而且采用无电阻防电解电源，一般均带有自动穿丝和恒张力装置。工作平稳、均匀、抖动小、加工精度高、表面质量好，但不宜加工大厚度工件。由于机床结构精密，技术含量高，机床价格高，因此使用成本也高。单向走丝电火花线切割机床早期只有国外公司的独有机种。台湾的低速走丝电火花线切割机起步虽然较晚，但这几年来发展迅速。其关键的一个举措就是由若干家电加工机床制造企业共同出资，在有关部门一定限度的支持下，由台湾工业技术研究院投入大量的人力、物力做关键技术的开发。经过10多年的攻关，在控制系统及电源等关键技术上取得了突破。台湾各企业制造的低速走丝电火花线切割机目前应属中档机的范围，近3年每年达到20%～30%的增长率，估计未来5年，台湾低速走丝电火花线切割机的年产量能达2000台，可占世界市场的25%以上。低速走丝电火花线切割机的技术含量高、市场前景好，可以获得较高的回报，是电加工行业各个厂家的“必争之地”、“战略高地”。也可以说，谁掌握了低速走丝电火花线切割机的技术，谁就获得了下一步企业发展壮大的机遇。为了抢占中国市场，日本、瑞士、台湾的电加工机床制造企业在中国大陆设厂生产这类机床。我国的科技工作者在科技部专项基金的支持下，投入了较大的研发力量，已完成新一代低速走丝电火花线切割机的研发，取得了重大突破，目前已拥有了具有自主知识产权的产品，并占领了一定的市场份额，其性能指标可达中档机水平。目前还有一些国内企业则希望通过与台湾相关企业的合作，来发展低速走丝电火花线切割加工技术。立式自旋转电火花线切割机立式自旋转电火花线切割机（卧式自旋转电火花线切割机）。立式回转电火花线切割机的特点与传统的高速走丝和低速走丝电火花线切割加工均有不同，首先是电极丝的运动方式比传统两种的电火花线切割加工多了一个电极丝的回转运动；其次，电极丝走丝速度介于高速走丝和低速走丝之间，速度为1～2m/s。由于加工过程中电极丝增加了旋转运动，所以立式回旋电火花线切割机与其他类型线切割机相比，最大的区别在于走丝系统。立式回转电火花线切割机的走丝系统由走丝端和放丝端两套结构完全相同的两端做为走丝结构，实现了电极丝的高速旋转运动和低速走丝的复合运动。两套主轴头之间的区域为有效加工区域。除走丝系统外，机床其他组成部分与高速走丝线切割机相同。与单向低速走丝电火花线切割机床相比，往复高速走丝电火花线切割机床在平均生产率、切割精度及表面粗糙度等关键技术指标上还存在较大差距。针对这些差距，本世纪初，国内有数家高速往复走丝电火花线切割机生产企业实现了在高速走丝机上的多次切割加工（该类机床被俗称为“中走丝” Medium Speed Wire cut Electrical Discharge Machining）。所谓“中走丝”并非指走丝速度介于高速与低速之间，而是复合走丝线切割机床，其走丝原理是在粗加工时采用8-12m/s高速走丝，精加工时采用1-3m/s低速走丝，这样工作相对平稳、抖动小，并通过多次切割减少材料变形及钼丝损耗带来的误差，使加工质量也相对提高，加工质量可介于高速走丝机与低速走丝机之间。因而可以说，用户所说的“中走丝”，实际上是往复走丝电火花线切割机借鉴了一些低速走丝机的加工工艺技术，并实现了无条纹切割和多次切割。经过几年的发展，国内几乎所有生产高速走丝电火花线切割机床的厂家都在生产及销售中走丝，但最终表明不是所有的往复走丝电火花线切割机都能进行多次切割，或者说不是所有的往复走丝电火花线切割机采用多次切割技术后都能获得好的工艺效果。多次切割是一项综合性的技术，它涉及到机床的数控精度、脉冲电源、工艺数据库、走丝系统、工作液及大量的工艺问题，并不是简单地在高速走丝机上加上一套运丝变频调速系统即可实现的，只有那些制造精度高，并在诸方面创造了多次切割条件的往复走丝电火花线切割机才能进行多次切割和无条纹切割，并获得显著的工艺效果。因此我们的生产企业必须充分注意到这个问题，一定要按系统工程来做，真正把这一技术用好，把这一产品做好。如目前已有一些企业为进一步提高机床本体精度，X、Y坐标工作台采用了直流或交流伺服电机作驱动单元直接驱动滚珠丝杠，同时采用了带螺距补偿功能的全闭环控制，可以利用数控系统对机床的定位精度误差进行补偿和修正。在保证精度的前提下，减小因长期使用而导致的加工精度下降，延长机床的使用寿命。运丝系统方面采用特殊（大多数采用金刚石）电极丝保持器，保持电极丝的相对稳定，减小加工过程中电极丝的张力变化。冷却系统方面改变常用的粗放冷却方式，采取多级过滤并对介电常数等关键参数加以控制，确保精加工的顺利进行。控制软件方面提供开放的加工参数数据库，可以根据材料的质地、厚度、粗糙度等条件选择对应的加工参数。相信经过我们的努力，多次切割技术将会更加完善，往复走丝电火花线切割加工技术也将得到更好的应用和发展。往复走丝电火花线切割机采用多次切割技术后，虽加工质量有明显提高，但它仍然属于高速走丝电火花线切割机的范畴，切割精度和光洁度仍与低速走丝机存在较大差距，且精度和光洁度的保持性也需要进一步提高。“中走丝机”具有结构简单、造价低以及使用消耗少等特点，因此也有其生存的空间，目前执行的标准仍然是高速走丝机的相关标准，因此生产企业在对用户的宣传上要注意，一定要实事求是。电火花线切割分类区分快走丝线切割，中走丝线切割，慢走丝线切割。1：快走丝电火花线切割的走丝速度为6～12 m/s，电极丝作高速往返运动，切割精度较差。2：中走丝电火花线切割是在快走丝线切割的基础上实现变频多次切割功能，是近几年发展的新工艺。3：慢走丝电火花线切割的走丝速度为0.2m/s，电极丝做低速单向运动，切割精度很高。

（1）用文字叙述：平均有效压 (MEP)———折合到每单位气缸工作容积的，每工作循环中的有效功，用单位活塞面积上假设不变的压力来表示。（2）用公式表示：Pme = We/vs = Pi ·ηm式中：Pme——平均有效压力 (MEP)We ——有效功（曲轴输出端的）Vs ——气缸工作容积（活塞排量）Pi ——平均指示压力ηm ——机械效率目前（1949年以后），美英教科书中的定义是：（1）用文字叙述：Mean Effective Pressure. ——Although the efficiency of the cycle depends only on r, the pressures, temperatures, and the work of the cycle depend on the values assumed for p1, T1, and Q2-3 as well as on the compression ratio. A quantity of especial interest in connection with reciprocating engines is the work done on the piston divided by displacement volume. This quantity has the dimensions of pressure and is equal to that constant pressure which, if exerted on the piston for the whole outward stroke, would yield work equal to the work of the cycle. It is called the Mean Effective Pressure, abbreviated mep. (文献 [2] ：P.27)The mean effective pressure may be indicated or brake, depending on whetherηis the indicated or brake thermal efficiency.(文献[2]：P.154)平均有效压力——虽然循环的效率仅决定于压缩比r，但是循环的压力、温度和功还与进气终点的压力（p1）、温度（T1）和循环加热量（Q2-3）的假定值，以及压缩比有关。所以与往复式发动机有关的一个具有特殊意义的量就是作用于活塞上的功除以排量(V1-V2)。该量具有压力的量纲，该压力在整个向外冲程中，以恒定的值作用在活塞上，所产生的功等于循环功。平均有效压力可以是指示的，也可以是制动的；视效率η是指示热效率，还是制动热效率而定。（2）用公式表示：mep.= w/(V1-V2) = J· Q2-3·η/(V1-V2) = J·pa·eV(F· Qc·η)= {J· Q2-3·（p1·m/MRT1）/(1-(1/r))} ·η式中：mep. —— Mean Effective Pressure. 平均有效压力W —— work of the cycle 循环功( V1-V2) —— piston displacement volume活塞排量J —— Joule"s law coefficient热功当量Q2-3 —— Heat which flows into the cycle 循环热量η —— efficiency of the cycle 循环效率pa —— density of sir at inlet valve 进气门处的空 气 密度eV —— measured or actual efficiency 测得的或实际 的 容积效率F —— fuel-air ratio 燃油-空气比Qc—— heat of combustion per unit mass of fuel单位燃油质量的热值p1 —— pressure at inlet end 进气终点压力m —— molecular weight of gas 气体分子量M —— mass of gas 气体质量R —— universal gas constant通用气体常数T1 —— absolute temperature at inlet end 进气终 点绝对温度从以上两种对“平均有效压力”的文字表述和公式表达，可以归纳出美英和中俄教科书中的不同含义如下：1， 在当前的中俄教科书中，不容许用“指示”和“有效”两个词，同时修饰“压力”一词。也就是说，“压力”不可能既是“指示的”，又是“有效的”；而在美英教科书中，容许“指示”和“有效”两个词，同时修饰“压力”一词。例如：“indicated mean effective pressure指示平均有效压力”。很显然，这是由于对“有效”这个概念，各有不同的含义所引起的。2， 在中俄教科书中，“有效”是对“机械效率”而言；但在美英教科书中，“有效”相对应的效率是不确定的，有可能是指示效率，也有可能是制动效率；可见，在美英教科书中的“平均有效压力”相当于我们的“平均压力”。他们的“制动平均有效压力”才相当于我们的“平均有效压力”。另一方面，在美英教科书[2]中，为了便于说明制动功率和指示功率之间的差异，常常采用了他们的“指示平均有效压力”的概念，不是采用我国教科书中的“平均指示压力”的概念。换句话说：以下各项“平均有效压力”(除bmep和tmep以外)都不是以（曲轴输出功率/气缸工作容积）为基础的。请看以下的定义：bmep = imep – mmep – pmep – cmep – amep + tmep= imep – fmep (文献[2]: P.313)式中：imep—— 指示平均有效压力，即示功图上所测得的有效功除以气缸工作容积mmep——机械摩擦平均有效压力，即指示平均有效压力中用于克服机械摩擦的那部分pmep ——泵气平均有效压力，即指示平均有效压力中用于克服泵气损失的那部分cmep ——指示平均有效压力中用于驱动增压器或扫气泵所损耗的那部分amep ——指示平均有效压力中用于克服驱动附件所损耗的那部分tmep ——废气涡轮所发出的，并施加给曲轴的制动平均有效压力fmep ——摩擦平均有效压力，即指示平均有效压力中用于克服摩擦 (包括：机械摩擦、泵气、驱动增压器或扫气泵、驱动附件和从涡轮取得)所损耗的那部分，也即指示与制动平均有效压力之间的差异。bmep——制动平均有效压力，即指示平均有效压力中减去用于克服摩擦损耗后所余下的那部分。在这个公式中，显而易见，只有“imep”才相当于我国教科书中的“平均指示压力”；bmep / imep =ηe ——(机械效率)为了清楚起见，列表如下：原文 直译（美英概念） 相当于中俄的含义mep 平均有效压力 平均压力imep 指示平均有效压力平均指示压力，即在示功图上测得的指示功除以气缸工作容积bmep 制动平均有效压力 平均有效压力，即平均指示压力中减去用于克服摩擦损耗后所余下的那部分。fmep 摩擦平均有效压力平均指示压力中用于克服摩擦所损耗的那部分，也即平均指示压力与平均有效压力之间的差异。mmep 机 械 摩 擦平均有效压力平均指示压力中用于克服机械摩擦的那部分pmep 泵气平均有效压力平均指示压力中用于克服泵气损失的那部分cmep 压气或扫气平均有效压力平均指示压力中用于驱动增压器或扫气泵所损耗的那部分amep 驱动附件平均有效压力平均指示压力中用于克服驱动附件所损耗的那部分tmep 涡轮平均有效压力 废气涡轮所发出的，并施加给曲轴的平均有效压力我们在[4]中，说文献[1]作者混淆了“平均有效压力”的概念，其原因就在于此。如果作者不考虑这些差异，原封不动地照搬，无疑就会造成这样的错误。这种错误难道不应该指出吗？还有，为了说明方便，在我们的教科书中，采用美英概念的“平均有效压力”来讲解制动功率和指示功率之间的差异，当然也是可以的。问题在于：①不能把他们的“平均有效压力”当作我们的“平均有效压力”；②必须保持等号两边衡等（请见以上bmep的公式）。不能一会儿用“功”来讲解；一会儿又用“平均有效压力”来讲解。例如：文献[1]中说：“从实际循环示功图的分析中可以发现，面积W以及掺和在面积x和y中的一小部分u（图中一交叉线表示）所表示的功损失，已经在求取平均有效压力时包括进去，故将换气损失中剩余的有面积（x + y – u）所表示的功损失，定义为泵气损失。”作者把“功”和“压力” 掺和在一起进行叙述，而且文中的平均有效压力又是中俄教科书中的概念，这样一来，不仅混淆了“功”和“压力”的概念，而且也混淆了“指示”和“有效”的概念
