EXPANDING SHAFT FOR MOTOR BODY TURNING

Asmita Industries is a leading Expanding Shaft manufacturer in India offering precision Expanding Shafts for Motor Body Turning. Engineered for rigid internal clamping, our expanding shafts deliver excellent concentricity, vibration-free machining, and repeatable accuracy—ideal for CNC turning of motor housings and stator bodies.

An Expanding Shaft for Motor Body Turning is an internal clamping device designed to grip motor housings from the bore (ID) during CNC turning operations. The shaft expands uniformly to center the component accurately, ensuring true OD machining, consistent wall thickness, and superior surface finish without deforming thin-wall motor bodies.

Key Features

  • Uniform 360° Expansion for precise centering
  • High Concentricity up to ≤ 0.01 mm TIR
  • Hardened & Precision Ground expanding segments
  • Rigid Core Design minimizes chatter at higher RPM
  • Replaceable Expanding Sleeves for long service life
  • Custom Bore Sizes & Expansion Range available

Applications

  • Motor body OD turning
  • Motor housing machining
  • Stator body turning
  • Electric motor manufacturing
