Abstract

The invention discloses a manufacturing process of a metal ceramic material for a numerical control cutter, and belongs to the technical field of numerical control cutter materials. The manufacturingprocess comprises the steps of (1), mixing raw materials, and filtering after wet grinding to obtain mixed slurry; (2), carrying out spray drying granulation on the mixed slurry through a closed-circuit solvent recovery spray drying tower; (3), pressing the mixed granules obtained in the step (2) into a green body by adopting an extrusion method; and (4), placing the prepared green body into a degreasing and pressurizing integrated sintering furnace, vacuumizing and filling argon into the sintering furnace before heating, filling hydrogen to completely replace the argon after heating, fillingthe argon again to completely replace the hydrogen when the temperature is continuously heated to 500-600 DEG C after glue discharging is completed, vacuumizing with a pump, continuously heating to 1,350-1,550 DEG C, keeping the temperature for 8-12 minutes before refilling with the argon, keeping the temperature for more 40-60 minutes, and naturally cooling to room temperature after reducing thetemperature to 900 DEG C by de-energizing. The manufactured material has zero porosity, high toughness, uniform structure, excellent mechanical property and durability.

Description

technical field [0001] The invention relates to the field of numerically controlled cutting tool materials, in particular to a preparation process of a cermet material for numerically controlled cutting tools. Background technique [0002] In recent years, the rapid development of my country's automobile industry has greatly promoted the development of the automobile mold industry. Since automotive molds are technical products and typical customized products, especially automotive panel molds have a very high technical content. How to improve production efficiency, shorten the development cycle, improve the level of mold technology, and reduce production costs has always been a problem faced by mold companies. Due to the different specific conditions of each mold manufacturing enterprise and the different businesses it undertakes, the specific process of automobile mold manufacturing in each enterprise is not the same. [0003] Now during the processing of various parts of...
