Wear forms of PCBN tool
1. Hollow wear workpiece hardness is too soft; Cutting too fast; Change to carbide or ceramic tools for chemical and diffusion wear; Use coolant to reduce tangential speed.
2. Pressure surface wear cutting speed is too fast; Too much feed; Too small cutting tool back Angle increases cutting speed and feed; After increasing Angle.
3. The main deviation Angle of boundary wear is too large; Too much feed; The tangential velocity is too small to reduce the main deviation Angle; Reduce feed; Increasing cutting speed.
4. The fracture wear system has poor rigidity; Knife Angle is too small; Too much feed and cutting speed; The brittle edge of the tool increases the rigidity of the system and the sharp Angle of the tool; Reduce feed and cutting speed and use the negative chamfering tool.
5. Poor rigidity of broken system in PCBN layer; Workpiece impact is too big; the PCBN layer is too thin, the cutting edge is too brittle to improve the rigidity of the processing system; Workpiece surface pre-machining and chamfering; Adopt thick PCBN layer; Use a negative chamfering tool.
The is reliable in performance and it is suitable for massive production of carbide inserts, PCD and CBN inserts. When the automatic tool grinding machine completes the centering, the grinding will also be completed automatically to achieve constant pressure grinding and flexible feed. The even consumption of the grinding wheel can be measured and compensated by the system, so production with long cycle time can be achieved. It is very popular for customers.
