HRC 55 Deg Tungsten Steel 2 Flutes Ball Nose End Mills

Raw Material： 

Use Zigong ZK30UF, high hardness and good wear resistance.

Coating： 

TiSiN, containing silica, very high surface hardness and high thermal resistance.

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.

Tolerance of End Mill Diameter:

Cutting parameters:

Cutting speed Vc = 130 (120-180) m / min

Cut depth ap = 1/3D (1 / 8-1 / 2D)

Single blade feed fz = 0.15mm (0.02-0.2)

Please adjust the parameters accroding to the material and hardness of workpieces.
