Integral type hard alloy cutter for materials difficult to machine and preparation method thereof

Abstract

The invention discloses an integral type hard alloy cutter for materials difficult to machine and a preparation method thereof. The material of the hard alloy cutter comprises the following components, by weight, 16-23 parts of titanium niobium alloy, 26-34 parts of copper molybdenum alloy, 22-28 parts of iron-nickel alloy, 4-5 parts of silicon sulfide, 9-11 parts of graphene, 4-6 parts of rare earth, 20-28 parts of graphite carbon fiber powder, 10-18 parts of cubic boron carbide micro powder, 15-18 parts of silicon dioxide, 9-12 parts of unsaturated resin, 5-9 parts of tungsten silicide and 5-7 parts of molybdenum carbide. The integral type hard alloy cutter has the beneficial effects that the rare earth, the graphite carbon fiber powder, the cubic boron carbide micro powder, the silicondioxide and the like are added, and therefore hardness and strength of the cutter are improved greatly; abrasion resistance and heat resistance of the cutter are also improved remarkably; the servicelife of the cutter is long, and practical cost is low; and pollution of the machining process is little.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an integral hard alloy cutter for difficult-to-machine materials and a preparation method thereof. Background technique [0002] Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has high hardness at 1000 °C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel. [0003] For the processing of some di...
