Abstract: 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.

Abstract: A machining apparatus includes: a workpiece spindle having a retainer that retains a workpiece having a noncircular peripheral surface; an adjustment unit that adjusts a retaining force between the workpiece and the retainer; a phase determination member that can determine a phase of the workpiece; and a phase determination detection unit that detects completion of the phase determination. The retaining force is a retaining force for phase determination until the phase determination is completed, and the retaining force is switched to a retaining force for machining which is larger than the retaining force for phase determination after the phase determination is completed.

Abstract: A printing method includes preprocessing a substrate by irradiating the substrate in a heated state with an activation light beam, and printing, after the preprocessing, a predetermined pattern on the substrate by ejecting a droplet to the substrate.

Abstract: A grinding wheel having a grindstone portion formed on a core includes slippery fluoroplastic coating films that prevent attachment of foreign matter, the coating films being provided on the portions of the core, with which portions the foreign matter can be brought into contact.

Abstract: A dynamic pressure in the coolant supplied between a rotating grinding wheel and a rotating workpiece is released by making at least one of oblique grooves on the grinding wheel pass vertically through a contact surface on which a grinding surface of the grinding wheel contacts the workpiece. Where one and the other side intersection points are defined as intersection points at which both ends of each oblique groove respectively cross extension lines of one and the other side edges parallel to a grinding wheel circumferential direction of the contact surface, the other side intersection point of each oblique groove overlaps the one side intersection point of an oblique groove next to each such oblique groove by a predetermined overlap amount in the grinding wheel circumferential direction, and the length in the grinding wheel circumferential direction of the contact surface is made to be shorter than the overlap amount.

Abstract: In a coolant supply apparatus for a grinding machine, a wheel imbalance prevention device is operated within the period from the switching to the closed state of a shut-off valve which is provided on a conduit connecting a coolant supply to a coolant nozzle, until the stop of rotation of the grinding wheel and prevents the coolant remaining in a part of the conduit on the downstream side of the shut-off valve and in the coolant nozzle from dropping on the grinding surface of the grinding wheel during the stop in rotation of the grinding wheel. Thus, the occurrence of coolant which otherwise penetrates the grinding wheel to put the same out of balance is prevented.
