摘要： A cam device includes a drive cam, a follower, a holding cam, and a restriction roller. The drive cam reciprocally rotates. The follower intermittently reciprocate linearly by the drive cam. The holding cam is rotationally driven integrally with the drive cam. The restriction roller is provided on the follower and restricts a movement of the follower by coming in contact with the holding cam. The holding cam separates from the restriction roller and the holding cam is in a holding release state, when the drive cam is in an engaged state with the follower.

摘要： A space-saving centerless grinding machine having high operability is obtained by devising the configuration of component units around the basic configuration of the machine. A dressing means for performing a dressing process for a grinding wheel and a regulating wheel comprises a single dressing unit. The dressing unit is located at a lower position between the grinding wheel and the regulating wheel, and thus eliminates the need for right and left dresser spaces for grinding wheels that have most seriously affected the breadthwise dimension of a conventional centerless grinding machine, leading to space saving and a considerable reduction in the breadthwise dimension of the centerless grinding machine.

摘要： [Problem] To enable efficiently grinding a workpiece of a hard brittle material, a difficult-to-cut material, or others at a moderate high load.[Solution Means] When surface-grinding a workpiece by a grinding wheel, a grinding load is monitored while the grinding wheel is reduced in cut-in speed when the grinding load rises and the cut-in speed is increased when the grinding load falls. Respective cut-in speeds with which the grinding wheel has a slower cut-in speed at a larger grinding load have been set in a manner corresponding to a plurality of respective load thresholds of the grinding load, and after starting grinding at a predetermined speed, the grinding wheel is decelerated or accelerated to a corresponding cut-in speed every time the grinding load rises or falls to a predetermined load threshold.

摘要： A telescopic shaft includes: an inner shaft where a pair of recessed grooves that face each other in a direction perpendicular to an axis and extend in an axial direction are formed; an outer shaft where a pair of recessed grooves that face each other in the direction perpendicular to the axis and extend in the axial direction are formed; a plurality of rolling bodies that are disposed between each of the recessed grooves and the corresponding recessed groove so as to form a line in the axial direction; a pair of stoppers; and a buffer body unit. Each of the stoppers restricts falling of a rolling body at an end portion of the corresponding line from the corresponding recessed groove of the inner shaft. The buffer body unit integrally includes a pair of buffer bodies, and a connection portion that connects the pair of buffer bodies.
