T.C.I. Optical products

imported ultra high wear-resistant high-grade high cobalt powder steel, quenched: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 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.

Imported ultra micro-grain diamond tungsten steel, 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.

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.

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.

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 stable. we can produce extreme complex and accurate Holder profile.
