Problems solved by technology

Whether it is adding a single oxide, or adding a ternary or multi-element oxide, it is a composite effect of components from the perspective of materials science. Each oxide particle exists in a separate phase in the tungsten matrix, and there is no tungsten involved. Alloying, still can not give full play to the performance, now there is an urgent need for a tungsten electrode material that is non-radiative, easy to process and has better performance

Abstract

The invention discloses a high-precision wire electrode and a preparation method thereof. The wire electrode is prepared from the following raw materials in parts by weight: 30-35 parts of Zn, 20-30 parts of Cu, 1.2-1.8 parts of Sm, 0.4-0.7 part of La, 0.05-0.15 part of Pm, 0.10-0.38 part of Nd, 30-38 parts of Mo, 8-44 parts of a heat-conducting material, 0.4-1.4 parts of a photo-thermal stabilizer and 1-5 parts of other elements. The wire electrode can has a certain Cu-Zn alloy layer, so that the gasification temperature is increased, more heat can be taken away, and the washing effect is improved. The preparation method has a simple process, high operability and a few preparation steps, employs simple production equipment, can easily prepare products which meet the demand, and can easily realize large-scale automatic production.

Description

technical field [0001] The invention relates to the field of electrode wire processing, in particular to a high-precision electrode wire and a preparation method thereof. Background technique [0002] In recent years, with the need for the processing of special and complex parts such as tiny parts - tiny gears, tiny splines and tiny connectors, EDM high-precision machining is especially suitable for its unique processing method, that is, the characteristics of non-mechanical contact processing. The requirements of micro-mechanical manufacturing, and has a high cost performance, so it has played an important role in many micro-mechanical production fields, and has developed rapidly. The continuous exploration of EDM high-precision wire-cut machining technology at home and abroad has made great progress in the combination and practical application of EDM high-precision wire-cut machining with micro-mechanical manufacturing. [0003] There are many factors affecting high-preci...
