Abstract

The invention belongs to the field of diamond grinding wheels, and in particular relates to a resin metal composite bonding agent and a composite bonding agent diamond grinding wheel prepared by adopting the resin metal composite bonding agent. The resin metal composite bonding agent consists of the following raw materials in percentage by weight: polyimide resin powder, copper powder, tin powder, zinc powder, phosphorus powder and lead powder; and the composite bonding agent diamond grinding wheel consists of the following raw materials: 65 to 85 volume percent of composite bonding agent, 15to 35 volume percent of diamond abrasive, and 0.5 to 1 volume percent of resin liquid. When the diamond grinding wheel prepared by adopting the resin metal composite bonding agent is used on a numerical control grinder, the diamond grinding wheel has the original characteristics of high grinding efficiency and good self-sharpening property of a resin bonding agent diamond grinding wheel and also has the advantages of high rigidity, high heat resistance and good profile retaining property of a metal bonding agent diamond grinding wheel, one-way cutting depth of heavy-load powerful grinding canreach 6 millimeters, and the comprehensive economic benefit can be improved by over 100 percent.

Description

technical field [0001] The invention belongs to the field of diamond grinding wheels, and in particular relates to a resin-metal composite bond and a composite bond diamond grinding wheel prepared by using the resin-metal composite bond. Background technique [0002] In the prior art, CNC grinding machines, especially multi-axis linkage CNC grinding machines, require high-speed, high-efficiency, high-precision, heat-resistant diamond grinding wheels with good shape and surface retention to adapt to their combined use characteristics. The grinding wheels traditionally used in CNC grinding machines are usually resin bonded diamond grinding wheels. The resin bonded diamond grinding wheel has high grinding efficiency and good self-sharpening, but it also has weaknesses such as insufficient rigidity, low heat resistance, and poor surface retention, which inhibits the performance of CNC grinding machines, especially when used in combination When a grinding wheel loses its shape, ...
