Benefits of technology

The invention improves the grinding of conical surfaces by reducing the difference in roughness between the close and far sides of the surface. This leads to more efficient processing of the work.

Problems solved by technology

Consequently, the difference in diameter on the conical surface WC of the work W causes a difference in grinding removal amount, which causes a difference in the finished surface roughness of the finished work.

Embodiment Construction

[0030]Hereinafter, an embodiment the present invention will be described by using the drawings. In the drawings, the x-axis, the y-axis and the z-axis are orthogonal to one another, the y-axis indicates a vertically upward direction, the z-axis indicates the direction of the work rotation axis ZW which is the rotation axis of the work W, and x-axis indicates the reciprocating direction of a turning platform 12.

[0031]Next, using FIG. 1 to FIG. 8(c), a grinding machine 1 in the present embodiment will be described. A first embodiment is the grinding machine 1 where a plane grinding wheel TP (corresponding to the grinding wheel) is disposed in an appropriate position on the turning platform 12.

[0032]1 (FIG. 1)>

[0033]As shown in FIG. 1, the grinding machine 1 is provided with a base 10, a main spindle table 11 capable of reciprocating in the z-axis direction on the base 10, and the turning platform 12 capable of reciprocating in the x-axis direction on the base 10, and the turning platf...

Abstract

In a grinding wheel truing method of an aspect of the present invention, an outer peripheral surface of a grinding wheel is trued while a position of a truer with respect to the grinding wheel is moved from one end side toward the other end side in the axial direction of the grinding wheel. In the truing, a relative movement speed of the truer when a position of the outer peripheral surface of the grinding wheel which grinds a large-diameter portion of a conical surface of a work is trued is lower than a relative movement speed of the truer when a position of the outer peripheral surface of the grinding wheel which grinds a small-diameter portion of the conical surface of the work is trued.

Description

TECHNICAL FIELD[0001]An aspect of the present invention relates to a grinding wheel truing method and a grinding machine adopting the truing method.BACKGROUND ART[0002]Conventionally, works of various shapes are processed on a grinding machine. For example, as shown in FIG. 9, there is a work W including: a spindle portion WA; and a disc-shaped portion WB which has a flange-shape protruding from a substantially center of the spindle portion WA and in which at least the surface on one side in the axial direction is formed into a conical surface WC. The conical surface WC of the work W is ground by a disc-type grinding wheel TA by bring the disc-type grinding wheel TA into contact with the conical surface WC while the work W is being rotated about the axis.[0003]The above-described grinding wheel TA is a so-called angular grinding wheel TA where, as shown in FIG. 9, a grinding surface TA1 on the periphery thereof is inclined with respect to a grinding wheel rotation axis ZTA and has a...
