TRUING METHOD AND TRUING DEVICE

摘要

In a state where a first truer rotation axis is maintained parallel to a grindstone rotation axis, a grindstone outer circumferential surface, and outer circumference arcuate surfaces which are partial surfaces of grindstone arcuate surfaces, and which are continuous to the grindstone outer circumferential surface are trued by using a first truer. In a state where a second truer rotation axis is maintained in a direction perpendicular to the grindstone rotation axis, grindstone end surfaces, and end surface arcuate surfaces which are remaining surfaces of the grindstone arcuate surfaces, and which are continuous to the grindstone end surfaces are trued by using a second truer.

1: A truing method which performs truing by using:
first and second truers which true a cylindrical grindstone that is rotated about a grindstone rotation axis to grind a workpiece; a moving unit which is configured to change a relative position between the first truer and the grindstone, and a relative position between the second truer and the grindstone; and a controlling unit which is configured to control the moving unit, wherein the first truer has a first roll which is rotated about a first truer rotation axis that is parallel to the grindstone rotation axis, the second truer has a second roll which is rotated about a second truer rotation axis that is perpendicular to the grindstone rotation axis, the grindstone has: a grindstone outer circumferential surface which is a surface that is parallel to the grindstone rotation axis; grindstone end surfaces which are surfaces that are perpendicular to the grindstone rotation axis; and grindstone arcuate surfaces which are surfaces in boundaries between the grindstone outer circumferential surface and the grindstone end surfaces, and which are formed into an arcuate shape, the truing method comprising: controlling the moving unit by the controlling means unit, in a state where the first truer rotation axis is maintained parallel to the grindstone rotation axis, to true, by using the first truer, the grindstone outer circumferential surface, and outer circumference arcuate surfaces which are partial surfaces of the grindstone arcuate surfaces and which are continuous to the grindstone outer circumferential surface; and controlling the moving unit by the controlling unit, in a state where the second truer rotation axis is maintained in a direction perpendicular to the grindstone rotation axis, to true, by using the second truer, the grindstone end surfaces, and end surface arcuate surfaces which are remaining surfaces of the grindstone arcuate surfaces and which are continuous to the grindstone end surfaces.
