- Bàn ren ngoài (tạo ren ngoài) use in repair and small batch work, including service workshops and mechanical engineering.
- Thread production on prepared holes or blanks where alignment is controlled by a holder, guide, or machine spindle.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: cắt ren, taro lại ren, and làm sạch ren depending on condition
- Use suitable lubrication and remove chips regularly so cutting edges do not pack up.
- Thread system context: match the tool to the M specification stated on the part or drawing.
Lưu ý Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.
