GRINDING WHEEL FOR GRINDING WORK AND CONDUCTIVE GRINDING WHEEL

摘要

PURPOSE: To provide uniform grinding in the circumferential direction of a disc-shaped grinding wheel and prevent chattering marks from occurring by fitting a conductive grinding belt in the circumferential direction integrally without seams at the external circumference of the conductive grinding wheel. ;CONSTITUTION: A conductive wheel 103 whose inner circumference is combined with the step-wise external circumference of the conductive wheel 102 through a layered vibration isolating material 104 such as epoxy resin and synthetic resin resinoid, having high elasticity and which is formed into a step-wise shape in its cross section is installed at the external circumference of the conductive wheel 102 whose external circumference is formed into a step-wise shape in its cross section, and is fixed by bolts 105. A grinding belt 101 is formed integrally without seams at the cylindrical external circumference of the conductive ring 103 to constitute conductive grinding wheel 1. The grinding belt 101 is formed by shaping super abrasives with conductive binder which is made up of various kinds of metals such as copper, silver, platinum, aluminum, zinc, titanium, nickel, chromium, cobalt, magnesium, iridium and beryllium or alloys made of more than two of these metals.;COPYRIGHT: (C)1996,JPO
