Problems solved by technology

[0007] However, in the grinding method disclosed in the aforementioned Japanese Patent No. 2001-47344, since the relative reciprocation between the piston W and the grinding wheel may not be completed even when the rotation of the piston W is completed, there is a problem of a long cycle time.
Moreover, in order to prevent such a problem, it is sufficient to synchronize the relative reciprocating movement of the piston W and the grinding wheel with the rotation of the piston W, but in order to achieve synchronization, the control of these actions becomes complicated.

Abstract

The present invention provides a grinding method capable of preventing abrasion of only a part of a grinding action surface of a cup-shaped grinding wheel, by changing a contact position of the cup-shaped grinding wheel and a work. The cup-shaped grinding wheel T having the annular grinding action surface and the cylindrical work W are respectively arranged so that these axes are mutually orthogonal, and the cup-shaped grinding wheel T and the work W are rotated around the axis. An outer peripheral surface of the work W is ground by contacting the grinding action surface with the outer peripheral surface of the work W. Every time when rotating the work W by a preset frequency in a state of contacting the grinding action surface of the cup-shaped grinding wheel T with the outer peripheral surface of the work W, the cup-shaped grinding wheel T and the work W are relatively moved in the direction orthogonal to both the axis of the cup-shaped grinding wheel T and the axis of the work W, to change a position for contacting the grinding action surface with the outer peripheral surface of the work W.

Description

technical field [0001] The present invention relates to a grinding method and a grinding device for grinding the outer peripheral surface of a workpiece processed into a cylindrical shape by using the grinding action surface of a cup-shaped grinding wheel having an annular grinding action surface. Background technique [0002] As an example of a cylindrical workpiece, for example, such as Figure 13 As shown, a piston W provided in a rotary compressor to compress a predetermined fluid includes vanes (protrusions) Wa formed on the outer peripheral surface and through-holes Wb opened on both end surfaces. in addition, Figure 13 (a) A plan view showing an example of a workpiece, Figure 13 (b) is along Figure 13 (a) Side view in the direction of the arrow. [0003] For the processing of the outer peripheral surface of the piston W, in the prior art, the cup-shaped grinding wheel and the piston W having an annular grinding action surface are respectively arranged so that their...
