Graphite end mill for metal processing is a special tool for graphite. What are the characteristics of Graphite end mill for metal processing? Now let's find out.
Compared with copper electrodes, graphite electrodes have the advantages of low electrode consumption, fast processing speed, good machining performance, high processing accuracy, small thermal deformation, light weight, easy surface treatment, high temperature resistance, high processing temperature, and electrode can be bonded.

Graphite end mill for metal processing manufacturers tell you that although graphite is a very easy to cut material, since the graphite material used as EDM electrode must have enough strength to avoid damage during operation and EDM processing, and the shape of the electrode (thin Walls, small rounded corners, sharp changes, etc. also put forward higher requirements on the grain size and strength of the graphite electrode, which leads to the easy collapse of the graphite workpiece and the easy wear of the tool during the processing.
Graphite end mill for metal processing manufacturers tell you that tool wear is the most important problem in graphite electrode processing. The wear amount not only affects the tool loss cost, processing time, and processing quality, but also affects the surface quality of the workpiece material processed by the electrode EDM, which is an important parameter for optimizing high-speed machining. The main tool wear areas for graphite electrode material processing are the rake face and the flank face. Graphite end mill for metal processing manufacturers tell you that on the rake face, the impact contact between the tool and the broken chip area produces impact abrasive wear, and the chips sliding along the tool surface produce sliding friction wear.
