Embodiment Construction

[0036] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] Figures 1 to 3 show the centerless grinding machine of the present invention, wherein like reference numerals designate like parts or components.

[0038] The centerless grinding machine of the present invention is in particular a machine tool for the simultaneous centerless grinding of a flanged workpiece W having many or more axes Wa by means of a feed system, in the illustrated embodiment, two workpieces W, W simultaneously Grinding, its main parts include grinding wheel 1, regulating wheel 2, blade 3 and correction device 4.

[0039] Grinding wheel 1 is used for grinding two workpieces W, outer peripheral surfaces of axes Wa, Wa of W, and a pair of wheel surfaces (outer peripheral surfaces) 1a, 1b have an outer shape corresponding to the final shape of axes Wa, Wa of workpiece W, and also That is, the axis Wa, the final profile of the outer perip...

Abstract

Provided is centerless grinding technique by which a plurality of workpieces are supported by a blade and simultaneously ground by an in-feed system. The rotation axis center of a regulating wheel is arranged in parallel to the rotation axis center of a grinding wheel. Inclined supporting faces of the blade arranged between the grinding wheel and the regulating wheel are upwardly inclined in the feeding direction of the workpiece so as to impart a thrust in the feeding direction to the workpiece. By this, two workpieces are supported by the blade and simultaneously ground by the in-feed system.

Description

technical field [0001] The invention relates to a centerless grinding method and a centerless grinding machine, in particular to a centerless grinding technology suitable for centerless grinding of the outer peripheral surface of a workpiece with a flange through an infeed system. Background technique [0002] In general, the centerless grinding of the infeed system is used to process the outer peripheral surface of workpieces that do not fit the shape of the through-feed system, such as workpieces with various stages in diameter or such workpieces with flanges at the ends . [0003] As shown in Fig. 4(a), by moving the driven grinding wheel (c) in the infeed direction relative to the workpiece W while rotating and supporting the workpiece W by the adjustment wheel (a) and the blade (b), the cross grinding method is A technique for grinding the outer peripheral surface of a workpiece W. In this case, as shown in Fig. 4(b), relative to the feed direction X of the workpiece ...
