The gang-type lathe ID workholding system is used on CNC lathes to clamp workpieces by their inner diameter.
- Gang-type CNC lathes are compact machines, generally preferred for bar stock machining and serial production. These lathes use a fixed tool slide (gang slide) instead of a traditional turret.
- The ID workholder (ID collet or chuck) clamps the workpiece from its inner surface.
- These workholders are generally:
- Collet type → Clamps the workpiece precisely by its inner diameter, ideal for serial production.
- Mini hydraulic/pneumatic chucks → Small-sized, specially designed to fit the compact layout of gang-type lathes.
- Mechanical chuck (3-jaw small chuck) → Suitable for simple operations, though collets are more common in gang-type setups.
Advantages: - Fast clamping and unclamping
- High repeatability
- Suitable for small, serial production parts
