Zhongshan graphite processing
Technical explanation:
Features of Zhongshan graphite processing:
1. Light weight: the specific gravity is 1 / 5 of copper, suitable for making large electrodes
2. Good machining performance: cutting resistance is 1 / 3 of copper& nbsp; Dongguan graphite products;
3. Easy surface treatment: no burr after machining, easy to handle by hand
4. High temperature resistance: when the temperature reaches 3650 ℃, sublimation gasification can withstand greater current
5. Low thermal expansion coefficient: 1 / 4 of copper, and no deformation when heated
6. High speed of electrical discharge machining: the speed of electrical discharge machining is 3-5 times higher than that of copper block, which is more obvious in large area or rough machining.
7. Small electrode loss: the ratio with copper is 2:4, which can be processed non destructively.
Machining method of graphite electrode:
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
