Tungsten alloy saw-tooth has good property in cutting and strength. Due to this property, it    can reach high speed cutting of 100-160m/min and time proof of tooling.
 

SKH4C: (a kind of high speed steel, which does not rust at all.)（Hardening treatment: HRC60°±2°）
This is super high hardness super mirror finish stainless high speed steel. It is characterized by excellent anti-rust, anti-corrosion, anti-worn (high hardness) and ideal impact resistance properties. It applies to a wide range. Its useful life is 3-6 times than normal stainless products. Moreover, AIS1440C and SUS440C are even better quality of incisiveness and much more excellent anti-worn properties. Under salt water circumstances, it's anti-rust capability could improve more than 10-20 times. Its quality is quite good and

ASP60C :
Imported super high wear-resistant high-grade high cobalt powder steel, quenched treatment:HRC70°±2°, with excellent wear resistance and impact resistance. Comparing with HSSE\HSS-AL and HSSCo, it has 4~8 times lifetime, and can guarantee uniformity and conformity rate of machined products. It is often applied in general equipment for machining various materials including Ni\Cr\Mo\Si\Ti) that are hard to machine like high temperature alloy\heat-resistant alloy\cast iron of nickel-vanadium-titanium alloy\stainless steel. It is excellent machining tool before heat treatment. It has excellent high temperature machining and comprehensive performance, and allows higher cutting speed. The higher the hardness of machined materials, the more remarkable the effect. Because its roughness is not so good, it is not suitable for discontinuous cutting or for using under processing system of insufficient rigidity, otherwise, cutter will be hit or chipping will happen.

VRA201:
Imported ultra micro-grain quality carbide, with excellent impact-resistance and general wear-resistance. Generally applied in worse or general equipment to machine materials of lower hardness （HRC≤25°）, discontinuous cutting and worse part fixture. Conforming to ISO K25, can replace machining of materials like M42, ASP60, MPM, HSSCo10 etc, and can get 4-6 times lifetime, it has higher performance/price ration. Comparing with SKH51, it has 15-25 times lifetime and durability.

HRF10:
ultra micro-grain quality carbide, has excellent wear resistance, but its impact resistance is not so good. It is applicable for medium and low speed cutting of high hardness materials(HRC45°-65°) requiring thermal refining and quenching or for various materials having higher wear resistance and non-ferrous metal. Generally it is applied in good working condition\stable cutting\excellent part fixing and continuous light machining. Corresponding to ISO K10.

When grinding, pay attention that the temperature can't be raised to cause the difference of internal stress so that cracking occurs, that is, it shall not be burnt, blacken or too hot, back rake angle, and back angle should be 2°4°lower than that of general mills

Attentions when grinding cutter:(Applicable reference for the milling by brazing tools)

During the grinding of ultra micro-grain quality carbide cutter, the temperature rise may cause cutter head to crack under thermal expansion stress, and during the cooling of the cutter, the similar situation will happen. At this time, the cutter will crack along the welding surface. To avoid this, when grinding, cutter body and cutter head shall be slowly grinded first, so that the temperature of cutter body and cutter head slowly increases and decreases.

There is a big difference between thermal expansion coefficient of ultra micro-grain quality carbide and cutter body, and there is also a big difference between the conductivity of ultra micro-grain quality carbide and cutter body. As far as the cutter head is concerned, if the temperature increases too fast during the grinding, the surface temperature will increase quickly, but the temperature of the inner ultra micro-grain quality carbide, due to its conductivity, doesn't increase together with the surface temperature, so a temperature grads occurs between the inner side and surface of ultra micro-grain quality carbide blade. Thermal expansion on each temperature layer is different, so it will produce very large internal stress area. When this stress is large to a certain extent, it will cause the cutter head to crack along the temperature difference area or lower cutting property. During the grinding, the cutter head changes as the above, but the cutter body's thermal deformation will occur due to the characteristic of its materials during the rough grinding. When they reach a certain temperature, stress area begin to form on the surface. The faster the temperature decreases, the larger, the stress. When this stress is larger than what the cutter head can bear, the cutter head will crack or lower property.

Besides, there is a big difference between the thermal expansion coefficient of cutter body material and cutter head material and there is also a big difference between the deformation extent during the cooling. Therefore, a shear stress layer occurs between the cutter head's grinding surface and cutter head's inner material, and the expansion speed with surface produces a big difference, so a shear surface occurs at the dividing surface of different expansion speed. The stress of this surface is substantial so that crack will occur or the cutting property will be lowered.
