Assigned to Cincinnati Milacron Inc. - Cincinnati, Hamilton County OH

Abstract: A grinding wheel is moved to a reference position by a hydraulic piston, which carries a stepping motor therewith. The stepping motor advances the grinding wheel into the workpiece at varying rates and for various distances depending on the desired size of the workpiece. After completion of advancement of the grinding wheel into the workpiece, the grinding wheel may be retracted to a predetermined distance before dwell occurs. Claim: A mechanism for producing relative movement toward and away from each other between a tool of a machine tool and a workpiece comprising: a feed member; fluid-responsive means including: a housing having a chamber therein; and a piston disposed in said chamber in said housing to produce relative translational movement between said housing and said piston when fluid is supplied to said chamber; said piston having means to rotatably support said feed member; first means connecting said piston to said feed member; said first connecting man including motive means to rotate said feed member relative to said fluid-responsive means; means to prevent relative rotation between said motive means and said housing; said means to connect one of said feed member and said housing to the movable one of the workpiece and the tool and to connect the other of said feed member and said housing to a fixed structure; and said second connecting means including means to convert rotational movement of said feed member to translational movement of the movable one of the workpiece and the tool; said motive means rotating said feed member both independently of movement of the movable one of said piston and said housing due to fluid supplied to said chamber and simultaneously therewith.
