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.

HTF 10 (Machining of super high wear-resistant and quenched and heat treated work pieces)

Ultra micro-grain quality carbide is ultra high wear resistant, but less impact-resistant. It is applied in mid and low speed light cutting of various materials that require ultra high wear resistance. Generally, it is applied in good work condition, stable cutting, good part fixture and continuous light-duty machining. Comparing with general tungsten steel, it has 4~6 times more life time. Conforming to ISO K10~K25/P10~P25.

MT 11 (For high wear-resistant application)

Ultra micro-grain quality carbide has property of excellent wear resistance and ideal impact resistance. It is applied in mid, high speed intermediate cutting machining of various materials that HRC 28°48°. It is an ideal machining tooling for finish machining and material tempering, and it is extensively applied. Comparing with general tungsten steel, it has 2~3 times more lifetime. Generally it is applied in good and stable work conditions, good part fixture and continuous mid, high speed light-duty cutting. After being TiALN coated, it has better performance, can machine various materials of HRC 60° Conforming to ISO K10~K30/P10~P30. It is often applied in CNC equipment to machine various hard-machining materials (containing Ni, Cr, Mo, Si, Ti etc.) like high temperature alloys, heat-resistant alloys, Ni-V-Ti alloys, cast iron, stainless steel etc., ultra excellent machining tools before heat-treatment and after tempering. High temperature machining and integrated property is good, allowing highest cutting speed (generally linear speed is above 120M) and with low feed requirement. The higher hardness of the machining material, the better performance. Due to its bad toughness, it is not applicable for discontinuous cutting or for conditions in which process system's rigidity is not sufficient and there is chattering, jumping, otherwise, the blade will be hit or chipping will happen.

HTF10 and MT11 (V350) adopts imported ultra micro-grain quality carbide with grain of 0.15/μm~0.25/μm. Generally, it is used in good and stable work condition, good part fixture and continuous high speed light-duty cutting. After being TiALN coated (high temperature coating is not allowed), it has better performance. Comparing with general micro-grain tungsten steel, it is less impact resistant and less chipping-resistant. Its bad grinding conductivity causes difference of internal stress, so it is easy to crack, but if grinding and using appropriately, its lifetime can be improved by 2~4 times, and can get higher product conformity rate and consistency.

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.
