Abstract

The invention discloses a processing method of a ceramic alloy cutting tool, which comprises the following steps: selecting Ni as the metal binder phase raw material, Ta, W, Mo, Cr, Ti carbide and TiCN as the hard phase raw material, the mass of each raw material The percentages are as follows: 15% to 20% of the metal binder phase raw material, 80% to 85% of the hard phase raw material; mixed, ball milled, dried and placed in a graphite abrasive tool under a pressure of 10‑15MPa in a hot pressing sintering furnace, Raise the temperature to 1500-1600°C for 2-7min in N2, then raise the temperature to 750-1800°C for 20-40min, then anneal at 1250-1300°C for 1-1.5 hours; then, use the prepared material to produce blank tools , Flat grinding on both sides, wire cutting, grinding, chamfering, and sharpening to make high-strength knives. The processing method of the present invention has reasonable technology, simple operation, low production cost, easy control of the process, and high production efficiency. The surface of the ceramic alloy tool prepared by the method does not contain a metal bonding phase enrichment layer, and the finished product produced has stable quality and high strength. , high temperature resistance, good wear resistance, it is worth promoting.

Description

technical field [0001] The invention belongs to the field of cutter production, and in particular relates to a processing method of a ceramic alloy cutter. Background technique [0002] With the development of high technology, the mechanical processing industry has put forward more stringent and demanding requirements for tool materials. Now it is necessary to process materials with higher hardness, higher cutting efficiency, and higher machining accuracy. This requires higher For the performance of cutting tools, traditional cutting materials such as high-speed steel are not hard enough, and scarce resources such as molybdenum and nickel are wasted, so ceramic cutting tools came into being. Ceramic cutting tools have the characteristics of high hardness, high density, high temperature resistance, anti-magnetization, anti-oxidation, strong corrosion resistance, good chemical stability, and high wear resistance, but they are still fragile, poor heat dissipation, and poor ther...
