<p>A collar plate clamps a rod-shaped circular workpiece (10) in a lathe. On rotation and cutting, metal swarf is removed by a wiper blade (31) integrated within a swarf guard (11), whose distance to the workpiece is maintained by a contact roller (5). The guard outer margin has one or more external swarf discharge passages (33) linked to internal swarf discharge passages (16) within the guard. The outer discharge passages are directed away from the roller.</p> |
