生产现代仪器必需要解决诸如截面为20—60微米,长10—15毫米的丝状振动元件、灵敏的扭矩吊丝等高精度丝状零件的复杂加工问题。断面尺寸的精度需要在十分之几或几个微米,加工表面粗糙度R不超过几十分之一微米。制造这种零件的方法之一是用无定型电极丝电火花精密加工。由于丝状零件没 The production of modern instrumentation has to deal with the complex machining problems of high-precision wire-form parts such as wire-shaped vibrating elements with cross sections of 20-60 microns and lengths of 10-15 mm and sensitive torque wire. The accuracy of cross-sectional dimensions needs to be in the tenths or a few microns, the processing surface roughness R does not exceed a few tenths of a micron. One of the ways to make such a part is by EDM EDM. Because of filamentous parts not
