MULTIPLE STATIONARY EXPANDING COLLET CHUCK HYDRAULIC

A Multiple Stationary Expanding Collet Chuck – Hydraulic is a non-rotating internal workholding system that uses hydraulic expansion to clamp multiple hollow components simultaneously from the inside diameter. It provides uniform 360° expansion, distortion-free holding, and high concentricity, making it ideal for thin-wall pipes, bushes, sleeves, and tubular parts in CNC lathes, SPMs, and automated production lines.

 
 

A Multiple Stationary Expanding Collet Chuck – Hydraulic is a fixed (non-rotating) internal clamping system designed to simultaneously clamp multiple hollow components from the ID using hydraulic expansion.
It is purpose-built for thin-wall pipes, bushes, sleeves, and tubular parts where OD clamping may cause deformation.

This system delivers uniform 360° internal expansion across all stations, ensuring distortion-free clamping, high concentricity, and maximum productivity in CNC lathes, SPMs, and automated production lines.

Applications

  • CNC lathes (stationary side operations)
  • Special Purpose Machines (SPM)
  • Bush, sleeve & pipe machining
  • Thin-wall & precision hollow components
  • Automotive & hydraulic parts
  • Mass production & automation cells
  • Boring, facing, OD turning & grinding operations

Key Features

  • Hydraulic internal expansion (ID clamping)
  • Multiple stations clamped simultaneously
  • Uniform clamping force across all components
  • Distortion-free holding for thin-wall parts
  • High repeatability & concentricity
  • Stationary design for maximum rigidity
  • Fast clamp/unclamp → reduced cycle time
  • Hardened & ground expanding segments
  • Automation-ready with sensors (optional)

Working Principle

Hydraulic pressure from an external HPU or integrated manifold actuates a central piston system.
This piston drives multiple expanding collets simultaneously, forcing each collet to expand radially inside the component bore, generating equalized clamping force at every station.

Types & Configurations

  • Multi-Station ID Expanding Collet Chuck
  • Thin-Wall Safe-Expansion Designs
  • Step / Multi-Bore Expanding Collets
  • Combination ID Expansion + Face Location
