1、 Characteristics of Electric Spark Graphite
Lightweight: The density of graphite is only 1/5 of copper, making it more suitable for making large electrodes.
Low loss: In the process of electrical discharge machining, the consumption of graphite electrodes is only 1/3-1/5 of that of copper electrodes, which helps to reduce processing costs.
High temperature resistance: The melting point of graphite is as high as 3650 degrees Celsius, so it will not deform at high temperatures and is more suitable for processing bone electrodes.
Good electrode adhesion: Damaged graphite can be bonded with conductive adhesive to save time and material costs.
2、 Application of Electric Spark Graphite
Electric discharge machining is a method of machining using electric discharge, widely used in fields such as cutting, drilling, and carving of metal materials. The graphite material used as a tool electrode for electrical discharge machining must have a dense structure, uniform organization, and should not have coarse particles or large pores; Has high mechanical strength and good processing performance, capable of processing complex shapes or sharp angles, thin sheets; Stable discharge characteristics and fast processing speed.
Therefore, electric discharge graphite generally adopts fine particle structure graphite or ultrafine particle structure graphite, which is isotropic in physical properties. In addition, imported high-end graphite (mainly isotropic graphite formed by isostatic pressing) also holds a certain market share.
In general, electrical discharge graphite is an important electrode material with characteristics such as light weight, low loss, high temperature resistance, and good electrode adhesiveness, which is widely used in the field of electrical discharge machining.
