Tool sticking during turning of sintered parts

Sintered PTFE parts stick to the tool during machining, resulting in poor finish. This problem is relatively common in sintering molding production and needs to be comprehensively analyzed and solved from multiple aspects of material, process, and equipment.

(1) Process factor: The PTFE material is soft and tough, producing adhesive wear and built-up edge in the cutting area; this factor affects the '2079851475616104453 and final quality of the product. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Deviations in the control of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment accuracy and maintenance status affect the stable execution of process parameters.

(1) Material selection: Use extremely sharp carbide or diamond tools, establish material selection evaluation standards, and determine the optimal plan through comparative tests. (2) Implementation measure: Large rake angle (<15°), high cutting speed, small feed, formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (3) Material selection: Use coolant to prevent temperature rise., establish material selection evaluation standards, and determine the optimal plan through comparative tests. (4) Preventive measure: Establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem needs to be comprehensively analyzed from multiple dimensions of material, process, equipment, and operation, and solved by systematically optimizing process parameters and the quality control system.
