Collet Mandrels
Expanding mandrels for lathes are ingenious, versatile tools that grip workpieces internally, offering precise and secure holding for turning operations. They solve common chucking problems, especially for thin-walled or irregularly shaped parts, making them essential for accurate results on any lathe.

Operating Principle
The basic concept involves a tapered shaft and an expandable sleeve. When a nut or screw is tightened, the sleeve is pushed along the taper, causing it to expand outward against the internal diameter of the workpiece. Loosening the nut or screw allows the sleeve to retract, releasing the grip. This simple mechanical action ensures reliable clamping and makes the system highly effective for precision machining applications. Features
