　　Superhard Tool SolutionsIt relates to a tool use method for processing hard alloy materials by combining laser and chemical action, which belongs to the field of mechanical manufacturing and the application field of new materials. The hard alloy material tools processed by superhard tool solutions can be used for precision and ultra-precision processing of carbon fiber composite materials, ceramic matrix composites, metal matrix composites, ceramic materials, hard alloys, high-temperature alloy materials, optical glass, non-ferrous metals, polymer materials, etc, let's understand the implementation process of the super hard tool solution together!

Carbon fiber composite materials have the advantages of high specific strength, high specific stiffness, low thermal expansion, thermal shock resistance, good shock resistance, good wear resistance, good fatigue resistance and corrosion resistance, etc., and are widely used in aerospace, national defense and military industry, New energy and other high-end equipment manufacturing fields. Carbon fiber composite materials can be used in military aircraft and civil large passenger aircraft 50%. Carbon fiber composite materials are widely used in high-speed trains. Wind turbine blades are made of carbon fiber composite materials, and the length of larger blades can reach more than 90 meters. High efficiency and precision machining technology is the key to restrict the application of carbon fiber composite materials, and superhard material tool is an important means to achieve high efficiency and precision machining. The high hardness and high strength of carbon fiber composite materials will cause excessive wear of diamond coated tools, which will seriously affect the processing efficiency and accuracy.

　　Superhard Tool SolutionsThe ceramic matrix composite material represented by the silicon carbide coating on the reinforced silicon carbide fiber braid has a temperature resistance of more than 2000 and a density of only 1/3 of that of metal alloys. It is used in engines with light weight and high fuel consumption. Ceramic matrix composite cmc has high specific strength, high specific modulus, low thermal expansion coefficient, low specific gravity, is not easy to wear, has excellent high temperature chemical stability, strong crack resistance, and is not easy to break in large areas. However, ceramic matrix composite cmc is a difficult material to machine because of its high hardness, high brittleness and low fracture toughness. It is difficult to give full play to the advantages of high temperature application of ceramic matrix composites because of the high efficiency processing of ceramic matrix composites without corresponding tools.

In order to improve the processing efficiency, ensure the processing quality, shorten the processing cycle, and meet the requirements of high-efficiency precision ultra-precision machining before nano-machining, the whole carbide material tool and its new processing method are needed. Through the processing of the whole polycrystalline diamond tool, it is found that foreign and domestic high-quality diamond grinding wheels cannot grind the chip removal spiral groove. Since the hardness of diamond grinding wheel and polycrystalline diamond are the same, sliding will occur when contacting, and grinding cannot be carried out. Wire electrode electrolytic grinding can process spiral grooves, but only for conductive carbide materials. Single crystal diamond, cubic boron nitride and other non-conductive cemented carbide materials can not achieve wire electrode electrolytic grinding.

Diamond is a hard material, its microhardness can reach 10000hv, excellent wear resistance, sharp cutting edge, small roughness value of the edge, low friction coefficient, good wear resistance, high thermal conductivity, cutting stick, grinding debris to diamond as the representative of the superhard material tool processing difficult materials, with high efficiency, long tool life, good processing quality and so on. Therefore, the development of the whole carbide material tool is a way to play the excellent physical and mechanical properties of difficult-to-machine materials, high temperature stability, structural shape complexity, technical realization elements:

The superhard tool solution is to provide a processing method for the whole hard alloy material tool, which combines the ultra-high speed laser direct gasification material with the material removed by the chemical reaction between the gas and the hard alloy material at high temperature, and realizes the high efficiency, precision and ultra-precision processing of the whole hard alloy material tool on the multi-axis numerical control machine tool. The air-floating static pressure linear axis equipped with micro-nano precision linear displacement sensor, the rotary encoder with degree second precision, the air-floating static pressure rotating axis, together with mineral cast stone bed, high-grade integral cast iron bed and granite bed, form a laser multi-axis numerical control machining center with micro-nano precision.
