Linear guide rail and method for working same |
摘要 |
When working a linear guide rail having one or more raceway grooves 2 on the side surfaces thereof, using rotary dies each including on the circumferential portion thereof a projection-shaped working portion matched in shape to the raceway groove 2, the raceway grooves 2 are rolled onto a rail blank work W. Since the raceway grooves 2 can be rolled with high accuracy by a single working step, the working time of the raceway grooves as well as the working cost thereof can be reduced.
