Description
Technical field
The present invention relates to the cutting-tool engineering field, be specifically related to a kind of steel rolling high strength industrial cutter and preparation technology thereof.
Background technology
Along with improving constantly of human living standard, demand to resource also constantly increases, and the operating cost of resource and further the difficulty the rock stratum in open up the new problem of being brought, brought the opposing of cutter has been broken and the intensity of repeated stress failure, the requirement that each side such as toughness and wear resistance is more and more higher, thus, have high-intensity high-abrasive material and new parts again to having high rigidity, new cutter, the cutter that adapts under the extreme condition is had higher requirement, traditional Wimet is because intensity and hardness height, wear resistance is good, red hardness is good, thermal expansivity is little, a series of premium propertiess such as Young's modulus height and chemical stability are good, it is widely used on the various cutters.
Machining is basic, the most reliable processing means in the mechanical workout, and the performance of cutter is one of deciding factor that influences machining efficient, precision, surface quality etc.Cutter material has experienced several developmental stage such as carbon tool steel, rapid steel, Wimet, pottery and superhard material.According to the data of CIRP, because the improvement of cutter material adds the cutting speed that allows man-hour and almost promptly improved 1 times every 10 years.In the modern course of processing, the most effectual way that improves working (machining) efficiency remains the employing High Speed Cutting Technique.Conventional tool can't be competent at needed various high-strength, the high hard machining that reach the high speed engineering materials of modern development in science and technology because of its limitation, sintex is showing the advantage that conventional tool is incomparable then with its excellent thermotolerance, wear resistance and chemical stability aspect high speed cutting field and the cutting difficult-to-machine material.
Sintex mainly contains two big classes on the domestic market at present: alumina base and silicon nitride base ceramic cutting tool.Compare with other cutter material, the significant disadvantage of sintex is exactly the fracture toughness property deficiency, and bending strength and thermal shock resistance are relatively poor, when cutting temperature is showing variation, are easy to generate crackle.As one of important indicator of estimating its resisting breakage ability, sintex need improve its hardness, bending strength and fracture toughness property by suitable means, and mill, plane, boring and other intermittently add man-hour, the fracture toughness property of blade material is even more important.
Summary of the invention
