GRINDING METHOD AND GRINDER FOR END SURFACE PLANE PART OF DISC-SHAPED WORK

摘要

PURPOSE: To ensure high-precision grinding by putting a grinding wheel to a work in linear contact by rotating the work and the grinding wheel, incliding a rotation axial center of the grinding wheel by a specified angle, and giving feed motion to the grinding wheel and the work in a parallel direction to a ground surface. ;CONSTITUTION: A grinding wheel 6f grinding a work 11 rotating clockwise is disposed to be inclined by a specified angle to a feed direction of an axial center C of its grinding axis. The grinding wheel 6f and the work 11 are thus kept to get in contact with each other at a part of (l) (l=Wcosθ, W is width of the grinding wheel) constantly, and feed motion is given to the grinding wheel 6f and the work 11 relatively, so the grinding wheel 6f is got in contact with the work 11 along the whole range. In this grinding method, the grinding wheel 6f and the work 11 are almost set in linear contact with each other, so grinding resistance can be extremely small, and the grinding wheel 6f can be easily positioned to pass the center of the work 11, thereby grinding work can be conducted with high precision.;COPYRIGHT: (C)1995,JPO
