Embodiment Construction

[0035]Hereinafter, embodiments of the present invention will be described using the drawings. In the drawings, the x-axis, y-axis and z-axis are orthogonal to each other, the y-axis indicates the vertical upward direction, the z-axis indicates the direction of the workpiece rotation axis ZW, the workpiece rotation axis ZW is the rotation axis of the workpiece W, and the x-axis indicates The reciprocating direction of the turntable 12.

[0036] Next, we will use the Figure 1 to Figure 8 (c) will describe the grinder 1 in this embodiment. The first embodiment is a grinder 1 in which a flat grinding wheel TP (corresponding to a grinding wheel) is provided at an appropriate position on a turntable 12 .

[0037] The general structure of figure 1 )>

[0038] Such as figure 1 As shown in , the grinding machine 1 is provided with a base 10, a spindle table 11 and a turntable 12, wherein the spindle table 11 can reciprocate on the base 10 along the z-axis direction, and the turn...

Abstract

This method for truing a rotary grindstone involves truing an external peripheral surface of a rotary grindstone while moving the position of a truer with respect to the rotary grindstone from one end side in the shaft direction of the rotary grindstone to the other end side. During the truing, the relative movement speed of the truer when truing a position on an external peripheral surface of the rotary grindstone for grinding a large-diameter part of a conical surface of a workpiece is less than a relative movement speed of the truer when truing a position on an external peripheral surface of the rotary grindstone for grinding a small-diameter part of the conical surface of the workpiece.

Description

technical field [0001] Aspects of the invention relate to a grinding wheel dressing method and a grinding machine employing the same. Background technique [0002] Conventionally, workpieces of various shapes are processed on grinding machines. For example, if Figure 9 As shown in , there is a workpiece W comprising: a shaft portion WA and a disc-shaped portion WB having a flange shape protruding from the approximate center of the shaft portion WA, and in the disc-shaped portion WB, along the axial direction A surface on at least one side of the direction is formed as a conical surface WC. The conical surface WC of the workpiece W is ground by the disc grinding wheel TA by bringing the disc grinding wheel TA into contact with the conical surface WC while the workpiece W is rotating around the axis. [0003] The aforementioned grinding wheel TA is a so-called angled grinding wheel TA, wherein, as Figure 9 As shown in , the grinding surface TA1 on the periphery of the angl...
