Raw Material：
Use Golden Egret GU25UF, high hardness and high toughness.
Coating：
Use nano-tech, the hardness and thermal stability are up to 4000HV and 1200*0 , respectively.
Tolerance of End Mill Diameter:
1 < D ≤ 6 | -0.010 ~ -0.030 |
6 < D ≤ 10 | -0.015 ~ -0.040 |
10 < D ≤ 20 | -0.020 ~ -0.050 |
Cutting parameters:
Cutting speed Vc = 130 (120-180) m / min
Cut depth ap = 1/3D (1 / 8-1 / 2D)
Cut width ae = 1/2D (1 / 4-1D)
Single blade feed fz = 0.15mm (0.02-0.2)
Please adjust the parameters accroding to the material and hardness of workpieces.
Double-edge design improves rigidity and surface finish effectively. Cutting edge over the center reduces the cutting resistance. High capacity of junk slot benefits chip removal and increases machining efficiency. 2 flutes design is good for chip removal, easy for vertical feed processing, widely used in slot and hole processing.
