Title:
GUIDE ROLLER FOR WIRE-SAW
Document Type and Number:
Japanese Patent JP2002292552
Kind Code:
A
Abstract:

To provide a guide roller for a wire-saw, automatically compensating the position offset of roller body from a wire way, and dissolving the fear of shortening the service life of a guide roller for the wire-saw and disengaging from the wire groove and breaking of the wire.

If the direction a of the wire groove 37a of the guide roller for the wire-saw is deviated from the wire way, a roller body 33 is moved by the amount necessary for compensation in compensating the direction for the position offset with the rotary shaft shifted by means of an equalizing mechanism 34. Then, the wire groove 37a of the roller body 33 is returned onto the same plane P as the wire way, resulting in automatic compensation for the position offset of the roller body 33. In such a way, decreased service life of guide roller 10 and disengagement from wire groove 37a or breakage of the wire W which are caused by the position offset, can be prevented.
