Lathe Three-Jaw Long-Stroke Power Chuck - 3SC

Lathe three jaw chuck with an ultra-long jaw stroke.
Can handle clamping of large diameters.
High rigidity structure and high clamping precision.
Inquiry
  • Three-Jaw: It has three jaws that move in unison to grip and release a workpiece.
  • Long-Stroke: The jaws have a longer travel distance than standard chucks, allowing them to accommodate larger workpieces or those with significant variations in diameter.
  • Power: It's operated by a hydraulic or pneumatic system, providing powerful clamping force.

Key Features:

  • Wide Clamping Range: Can hold a wide range of workpiece diameters.
  • High Clamping Force: Ensures secure grip for heavy-duty machining.
  • Fast Clamping and Releasing: Improves productivity.
  • Repeatability: Consistent clamping accuracy for precision machining.

Applications:

  • Turning large workpieces: Where a standard chuck wouldn't reach.
  • Machining parts with varying diameters: Like stepped shafts or tapered components.
  • Heavy-duty machining: Where high clamping force is required.
