1 introduction

Generally the one-way wire speed below 0.2 m/s wire cut edm of wire cut processing method as the walk slowly. Take care of wire cut has high precision cutting size and good surface quality characteristics, can guarantee the good surface roughness, do a precision, basic size accuracy etc. Take care of wire cut electrode wire transfer for one-way transmission, disposable, so nonexistent wire electrode thinner. Because of wire cut went silk take a slow speed, wire electrode dithering also small, can suit the bigtaper cutting processing. In view of many of the processing of wire cut take advantage, now mainly introduces how to take care of wire cut processing layer by the most representative in multiplier bigtaper abnormity bores.

2 processing difficulties analysis

Layer multiplier is composed of six plates with different kind parts assembly and become, material is S136, after quenching and tempering treatment 35HRC hardness reach. Now choose one of the most representative board as example to illustrate. Machining difficulty analysis is as follows:

(1) general take care of wire cut processing taper in 0 ~ 30 °, and the processing of abnormity bores taper for 41 °, belongs to the special processing type, shown parts structure as shown in figure 1.

(2), below 4 holes on the side before 8 shape, and the rectangular ㎜ ㎜ x 6 holes, another side is 6 ㎜ 6x8 ㎜ rectangular hole, need to find their common standards for processing, can use "tote the methods select points in" processing center as the workpiece benchmark.

(3) the layer between the plate for multiplier plastic melt flowed, former board after the hole of the board with a higher position precision needed to prevent leakage of hole materials, the surface quality of the position precision and the demand is higher, especially in large taper wire-cutting processing is particularly obvious.

(4) the processing of 41 ° bigtaper abnormity bores needs a special wear silk hole drilling machine, usually only processing straight to wear silk hole, need to do a special special tooling.

(5) use normal processing method processing this abnormity bores residual material cannot remove, so need woven two programs. Use a special 2 times to complete the processing methods.

(6) in try processing process, because the bigtaper ° 41, make fluctuation godet mouth stagger, scraps liquid can"t flush the machining parts and could easily broken wires in processing hole, which is obvious, need unifies the corner some process parameters machine itself and the actual processing situation of process parameters modification.
