FAQs:
Q: What thread specifications (metric/inch) are available? What is the thread accuracy grade?
A: Standard metric M3-M16, inch #6-32 to 1/2"-20, and Whitworth threads are available, with accuracy grade up to 6H/6g (internal 6H, external 6g). Non-standard or fine-pitch threads can also be customized upon request.
Q: What processes are used for threading and knurling? How do you ensure knurling doesn't damage the threads?
A: Threads are formed by cold heading + precision turning or extrusion + turning. Knurling is performed by hydraulic rolling or turning knurling. Strict CNC programming and fixture design ensure the knurling tool operates away from thread areas, or knurling is done after thread completion, completely preventing damage to thread accuracy.
Q: What are the surface roughness, thread go/no-go gauge requirements, and overall appearance standards?
A: Surface roughness Ra≤1.6μm (knurled area Ra≤3.2μm), 100% go/no-go gauge inspection for internal threads, no scratches, burrs, or cracks, both ends chamfered C0.2-C0.5, compliant with ISO 2768-mK or customer-specified standards.
