5 Requirements And Characteristics Of Good Cutting Wire

DALIAN, China - April 2, 2023 - PRLog -- 1. Good Mechanical Performance And High Cutting Efficiency

As a tool electrode for cutting, the cutting wire must meet the requirements of relevant mechanical properties. During EDM corrosion processing, the cutting wire needs to bear a certain tensile force and electric spark impact force caused by discharge. This tensile force and impact force must be borne by the material meeting a certain mechanical strength. If the strength of this material is too low or the fracture toughness is too low, the cutting wire will shake during cutting, Finally, the surface of the cutting workpiece will be unsmooth, and even lead to cutting line marks one after another, which will cause broken line in the worst case.

Especially for some metal parts that are difficult to cut, the greater the tension applied during cutting (the strength of the material forming the cutting wire), the easier it is to cut. In addition, the strength also plays a role in ensuring the function of restoring the straightness of the cutting wire. The cutting wire material with certain toughness is also beneficial to cutting the workpiece with slope. How to make the cutting wire material have excellent mechanical properties and ensure the high efficiency of cutting depends on the cutting wire manufacturer selecting appropriate processing technology and selecting superior copper and zinc.

2. Excellent Physical Characteristics, More Stable Cutting

These characteristics are determined by the basic composition ratio of the cutting wire material and the constituent metal of the core material. The physical properties here usually refer to the melting point of the cutting wire. The melting point is the key to improve the cutting efficiency, because the jitter of the cutting wire during discharge will produce instant short circuit effect. At this time, the discharge process will slow down. If the metal on the surface of the cutting wire is not ablated during discharge, there will be no gap between the cutting wire and the cutting metal, then the generated cutting scrap will not be discharged under the action of water, and the cutting wire will be burned, Affect efficiency and cutting. From the perspective of physics, the melting point is the basic property of a material. Once the material is determined, the melting point is determined.
