摘要： A method for measuring the diameter and eccentricity of a crankpin of a crankshaft which is ground on a grinding machine. A reference plate is provided on a headstock, which is disposed on a table to support the crankshaft. A measurement apparatus having a probe is disposed on a wheel head. Through movements of the table and the wheel head, the probe is first brought into contact with a reference surface of the reference plate, and is then brought into contact with the outer circumferential surface of the crankpin at outermost and innermost points. The distances between the reference surface and the outermost and innermost points are measured, and the diameter and eccentricity of the crankpin are calculated on the basis of the measured distances and the position of the reference surface.

摘要： 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.

摘要： 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.

摘要： On a grinding machine, a workpiece having eccentric cylindrical portions is rotated around the work spindle axis so that the eccentric cylindrical portions effects a planetary motion. A grinding wheel is reciprocated toward and away from the work spindle axis in synchronism with the planetary motion and is also fed toward the work spindle axis to grind the eccentric cylindrical portion into a target cylindrical profile. Upon completion of a part of the grinding operation, the eccentric cylindrical portion under machining is indexed to a predetermined angular position. A diameter measuring device is moved from its rest position to a measuring position to measure the diameter of the eccentric cylindrical portion. Comparing the measured diameter with a target diameter to obtain a residual difference in diameter, the grinding machine further operates to perform a finish grinding according to the residual difference until the diameter reaches the target size, whereby the eccentric cylindrical portion can be finished precisely using a general purpose measuring device.
