Abstract
A rod-shaped workpiece W is supported at its circumferential surface by a shoe 14 and a pair of rolls 16 and 17, and is rotated by the rolls 16 and 17. The rod-shaped workpiece W is ground by being abut against a backing plate 19 at its one end by the rotation of the rolls 16 and 17, and put in abrasive contact with a sectionally arch-shaped groove-like circumferential surface 20b of a grinding wheel 20 at its other end surface. A floating plate 37 is provided so that a slight gap takes place is in a guide hole 42 of a housing 36. A sphere 39 supported by a support member 38 is provided in a retaining recess 47 on a rear end surface of the floating plate 37, and the floating plate 37 is swingably supported.
Claims7
A rod-shaped workpiece grinder comprising:
- a shoe which abuts against a circumferential surface of a rod-shaped workpiece supplied in a grinding position;
- a pair of rolls which rotatably abut against the circumferential surface of said rod-shaped workpiece, at least one of the rolls being able to be put in and out of contact with said rod-shaped workpiece, at least one of the rolls being driven to rotate;
- a backing plate which abuts against a rear end surface of said rod-shaped workpiece;
