Description

technical field [0001] The invention relates to a milling and grinding tool, in particular to a milling and grinding tool capable of realizing efficient processing of inorganic composite materials, belonging to the field of cutting processing. Background technique [0002] Inorganic composite materials, especially metal matrix composite materials, have excellent comprehensive properties such as high specific strength and specific modulus, high temperature resistance, wear resistance, fatigue resistance, small thermal expansion coefficient, and good dimensional stability, so they are widely used in aerospace, Advanced weapon systems, automobiles, optical precision instruments, electronics and many other fields. The acquisition of a series of excellent properties of this type of composite material is at the expense of the plasticity, toughness and machinability of the composite material. Due to the low plasticity and microscopic inhomogeneity, the material is difficult to mach...

[0005] (2) The cutting quality of metal matrix and ceramic matrix composite materials is not easy to guarantee

[0006] (3) Although a variety of processing methods for inorganic composite materials have been researched and developed by some research institutions at home and abroad (such as PCD diamond tool cutting technology, ultrasonic vibration cutting technology, electrical processing technology, grinding technology, laser processing technology, etc. ), but these technologies have different degrees of limitations, including tool life issues, processing quality assurance issues, and complex curved surface processing issues. Engineered mass production

[0007] (4) The above-mentioned metal matrix / ceramic matrix composite materials are new materials developed in recent years. It is difficult to find process data for engineering application in the current literature, materials, and manuals to guide production, and it is difficult to form standardized parts processing process documents , which also limits the engineering application of these materials

[0010] According to the recent relevant literature, the results show that the milling cutters such as cemented carbide and high-speed steel are found to be severely worn when milling metal matrix composite materials, especially when processing inorganic composite materials with large particle size and high particle content. It will be accompanied by chipping of the tool, and edge chipping often occurs at the edge of the workpiece, which seriously restricts the high-precision and high-efficiency processing of such materials; there are few reports on the grinding of such materials, and for straight and narrow The processing and grinding of grooves, cavity parts and special curved surfaces has not been solved well
