Problems solved by technology

[0002] At present, the known copper and chrome heat-conducting cubic boron nitride grinding wheels, referred to as CBN grinding wheels, are composed of CBN abrasives, binders, fillers, etc., and the abrasive layer is a heat insulating material. When grinding parts with small heat capacity, the grinding area The heat is too late to spread to the inside of the grinding wheel, which often causes burns on the workpiece and causes the parts to be scrapped

Embodiment Construction

[0009] Such as figure 1 , 2 As shown, an aluminum alloy substrate 1 is included, and a thermally conductive cubic boron nitride abrasive layer 2 containing copper and chromium alloy particles 3 is arranged on the aluminum alloy substrate. The abrasive layer is composed of cubic boron nitride, copper, chromium alloy particles and adhesive Binder composition.

[0010] The volume percentage of each raw material of the heat-conducting cubic boron nitride abrasive layer containing copper and chromium alloy particles is 90% of cubic boron nitride, 8% of copper and chromium alloy particles, and 2% of binder, of which copper and chromium alloy particles The volume is 1:1.

[0011] A preparation process for a heat-conducting cubic boron nitride grinding wheel. First, a heat-conducting cubic boron nitride abrasive layer containing copper and chromium alloy particles is produced: use cubic boron nitride as the abrasive and add vitrified bond, copper and chromium alloy particles, and st...

Abstract

The invention relates to a copper and chrome heat conducting cubic boron nitride abrasive wheel and its production technics. The heat conducting cubic boron nitride abrasive wheel includes aluminum alloy basal body coated with heat conducting cubic boron nitride abrasive material which consists of cubic boron nitride, copper and chrome alloy particles and adhesives with their volume ratios of cubic boron oxide 90 percents, copper and chrome alloy particles 8 percents and adhesive 2 percents. First produce the abrasive material by adding ceramic adhesive, copper and chrome alloy into the cubic boron nitride rabbling, screening and shaping. And then press the material on the basal body and trim it to make is usable. It greatly lowers the abrading area temperature to prevent the component from being burned while maintaining the advantages of CBN abrasive wheel in grindability and particle sharpness.

Description

technical field [0001] The invention relates to a copper and chrome heat-conducting cubic boron nitride grinding wheel suitable for grinding small-volume parts such as spinning frame spindle bar spindle tip friction plates and a preparation process thereof. Background technique [0002] At present, the known copper and chrome heat-conducting cubic boron nitride grinding wheels, referred to as CBN grinding wheels, are composed of CBN abrasives, binders, fillers, etc., and the abrasive layer is a heat insulating material. When grinding parts with small heat capacity, the grinding area The heat does not have time to spread to the inside of the grinding wheel, which often causes burns on the workpiece and causes the parts to be scrapped. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a copper and chrome heat-conducting cubic boron nitride grinding wheel that can increase the thermal conductiv...
