Customer Requirement
Using the Shenyang CAK50186 machine tool matches with the GSK 980TDi, its processing length is 1.8m, and the hollow long shaft with 86mm diameter is performed the outer circle knurling. It is demanded that the knurling depth is 1mm, and the whole depth should be consistent and its wave should be clear and without disorder wave.
Troubleshooting
- Fixture method: Clamping once and injecting once + following the tool-post;
- Machine tool requirement: Level aviation of machine tool is less than or equal to 0.02mm;
- Accordant aviation both the tailstock and spindle is less than 0.05mm, the interface between tailstock and workpiece is more than 3mm;
- The center height of the dual-wheel knurling tool and the workpiece center should be absolute precision, and the error should be within 0.05mm;
- The infeed of knurling should be performed the cut-in by using the gradual right-left wave method;
- Coolant ready.
Machining Effect - There is no vibration wave when the workpiece machines the out circler; the knurling depth is 1mm;
- The depth of whole wave is consistent and its wave is clear without disordered waves.
