Product Overview
A Pneumatic Rotary Collet Chuck is an air-operated, rotating work holding device designed for fast, accurate, and repeatable clamping in CNC lathes, turning centers, and automation lines.
It delivers uniform 360° gripping, enabling high spindle speeds, reduced setup time, and consistent part quality—ideal for mass production.
Key Advantages
• Fast clamping/unclamping with compressed air
• High concentricity & repeat accuracy
• Rotary design for high-speed machining
• Interchangeable collets (ER / 5C / Traub / Special)
• Automation-ready (robots, gantries, bar feeders)
• Low maintenance, long service life
Working Principle
• Compressed air enters the chuck body
• Internal piston actuates the draw mechanism
• Collet closes uniformly on the job
• Air release opens the collet instantly
Result: reliable, repeatable clamping every cycle.
