Technical explanation:

Graphite electrode machining method: Dongguan graphite machining
1. Tool requirements: sharp, with large front and rear corners and chip receiving grooves
2. Cutter material: carbide cutter, coating cutter, diamond cutter
3. Feed speed: 5500 ~ 8000 for rough machining and 4000 ~ 6000 for finish machining
4. Machine speed: 6500 ~ 10000 rpm for rough machining; Finishing 6000 ~ 20000 rpm
5. Machining allowance: rough machining 0.6mm; Finishing: 0.3mm
6. Cutting amount: the lateral cutting amount is 1 / 2 ~ 2 / 3 of the tool diameter, and the depth cutting amount is 1 ~ 1.5 times of the tool diameter
7. Cutting direction: cutting direction is better than upper cutting and down milling is better than down milling

Characteristics of graphite electrical discharge machining:
A: It is cheap, economical and practical.
B: Capable of receiving large current, fast discharge speed and high efficiency.
C: It is not easy to deform, and is suitable for thin bone position (RIA) processing.
D: At present, the mirror discharge needs to be improved.
