Method of making camshaft lobes |
摘要 |
Sharp edges formed during forging are removed from cam lobes by tumbling prior to machining of mounting bores which have been rough formed by punching. Tumbling effectively removes the sharp edges from non-hardened steel and prevents the formation of burrs caused by prior grinding techniques.
