GRINDING METHOD AND GRINDING DEVICE FOR WORKPIECE CYLINDER EXTERNAL DIAMETRIC SURFACE

摘要

PROBLEM TO BE SOLVED: To provide grinding technique whereby a machining region except non-cylinder part is efficiently finished highly accurately with high circularity, cylindricity, etc., in a workpiece cylinder external diametric surface including a protrusion or the like. ;SOLUTION: In a flat circular annular grinding surface 1a of a cup-shaped grinding wheel 1 driven to rotate, while a cylinder surface 100 of a workpiece W is brought into contact, it is turned in a circumferential direction of the cylinder surface 100, grinding work is applied to a machining region total surface except a protrusion Wb in the cylinder surface 100. Here, contact of the grinding surface 1a with the cylinder surface 100 is placed in a line contact condition in parallel to a center axial line of the cylinder surface 100, a workpiece turn direction is in a direction orthogonal to a rotational direction of the grinding wheel 1, and a workpiece turn range is in a range of an edge circle contour of the grinding surface 1a without interfering with the protrusion Wb. In this way, without interfering with the arm part Wb of the grinding surface 1a, a uniformly accurate finish can be applied to a cylinder surface machining region total surface.;COPYRIGHT: (C)1998,JPO
