Performance test manner null of binder for abrasive grain formation of super abrasive grain

摘要

PURPOSE: To perform evaluation of performance adapted to the actual using state of a binder for the grinding grain layer of a super grain grinding wheel without performing an actual polishing test. ;CONSTITUTION: A test piece S formed of super grains grinding similar to those of the grinding grain layer of a super grain grinding wheel and a binder is pressed against a test tool 1 comprising a super grinding grain metal bond wheel with a constant force. With this state, the test tool 1 is rotated as ultrasonic vibration generated by an ultrasonic vibrating device 2 is exerted on the test tool, and a grinding work is applied on the test piece S by means of the test tool 1.;COPYRIGHT: (C)1993,JPO&Japio
