Abstract

A diamond grinding wheel and its preparation method, belonging to the field of superabrasives; the grinding wheel includes a steel core and an abrasive ring. The steel core and the abrasive ring are bonded by a resin bonding agent. The abrasive ring is composed of diamond abrasives, metal bonding agents and auxiliary agents. It is prepared from a binder; the metal binder contains Cu powder and Ti powder; the abrasive ring is composed of: diamond abrasive, metal binder and pores; preparation method: 1) Mix the diamond abrasive, Cu powder and Ti powder evenly to obtain a mixture Material A; 2) Mix the auxiliary binder and Mixture A evenly to prepare Mixture B; 3) Dry Mixture B; 4) Sieve the dried Mixture B; 5) Sieve the The final mixture B is cold-pressed and formed; 6) The green abrasive ring is sintered under an inert gas atmosphere to obtain the abrasive ring body; 7) Use a resin adhesive binder to combine the abrasive ring body with the steel core Bonding to produce a diamond grinding wheel.

Description

technical field [0001] The invention relates to the field of superhard abrasives, in particular to a diamond grinding wheel and a preparation method thereof. Background technique [0002] With the development of modern machining in the direction of high precision, high speed, hard machining, dry machining (no coolant) and cost reduction, quite high requirements are put forward for the performance of abrasive tools. Traditional silicon carbide and corundum ordinary abrasive molds can no longer fully meet the current high-speed, high-efficiency, and high-precision grinding requirements. Therefore, it is an inevitable development to develop various superhard grinding materials with excellent wear resistance and stable processing for a long time trend. Currently commonly used superhard grinding materials include diamond and cubic boron nitride abrasives. Diamond is the hardest material and is extremely wear-resistant, suitable for high-speed grinding and ultra-precision grindi...
