Material: HSS (M2/M35)

1.HSS: High Speed Steel

1).Total alloying elements: 10~25%

2).Vc=25~30m/min

3).Red hardness: 600°C

4).Type: (1) W18CR4V (2) W6Mo5Cr4V2 (3) W6Mo5Cr4V2Co5, W6Mo5Cr4V2Co8

2.M2 (W6Mo5Cr4V2)

Coat: TIN/TIALN

1.TIN

1).TiN is a kind of high hardness, abrasion resistance, wide application of coating materials.

2).TiN is the ideal of low-speed cutting tool coating materials, can reduce the adhesion of cutting edge materials, reduce the cutting force, increasing the feed quantity, improve the machining accuracy, maintain the stability of cutting geometry, improve the surface quality of workpiece.

2.TIALN

1).TIALN is a new coating material which has high hardness, good oxidation resistance, small friction coefficient and has been found broad prospects in high speed cutting.

2).Function:

Coat Material	HV	GPa	°C
TIN	2300	260	600
TIALN	3300	380	900
