CNC Turning Definition & Terminology
Back to Glossary
CNC Turning – CNC turning is a catch-all term for the various forms of CNC lathe work we perform. Depending on the job being done and the machine being used, turning could mean:
- Pinch Turning – The process of using two independent tool turrets on a CNC lathe. Pinch turning allows for faster cuts, and can be used to perform rough turning and finish turning in the same pass.
- Contour Turning – The process of turning a smooth continuous curve on the machine. Contour turning requires specialized bits, and an experienced technician to produce a perfect curve.
- Follow Turning – Any turning process utilizing two independent tool turrets on the lathe. Pinch turning is a form of follow turning. Not all CNC shops can perform detailed follow turning.
- Horizontal Turning – Any CNC lathe which rotates horizontally.
- Vertical Turning – Any CNC lathe which rotates vertically.
