CNC Clamping Systems for Tubular Workpieces

To address common machining challenges such as deformation, runout, and concentricity control, Grand E-Light provides professional CNC clamping solutions for tubular workpieces.

Depending on the workpiece dimensions, wall thickness, and machining requirements, different clamping methods can be provided, including external clamping and internal expanding clamping.

By applying uniform clamping force around the workpiece, the collet system provides stable support and improved concentricity during machining. This helps reduce the risk of deformation caused by localized clamping forces and is suitable for precision machining of tubes, sleeves, hollow components, and other tubular workpieces.

 

 

Product Features

✅ High-Precision Concentric Clamping

The precision collet structure provides uniform clamping around the workpiece, helping improve concentricity and overall machining accuracy.

✅ Uniform Support with Reduced Deformation

The collet applies multi-point, evenly distributed clamping force to the workpiece, reducing localized stress and minimizing deformation, especially when machining thin-wall tubes.

✅ External and Internal Clamping Options

The clamping method can be selected according to the workpiece structure, including external clamping and internal expanding clamping, providing greater flexibility for different machining applications.

✅ Stable and Reliable for Precision Machining

With excellent clamping rigidity and positioning stability, the system helps reduce runout and vibration during machining, improving machining quality and process consistency.

✅ Customized Clamping Design

Clamping systems can be customized according to tube diameter, inner and outer diameters, wall thickness, machining area, and machine specifications to provide a solution tailored to the actual production requirements.

 

External Clamping Solution for Tubes

A specially designed collet expands outward to provide uniform clamping around the outer diameter of the tube.

This solution is suitable for applications where the internal space of the tube needs to remain accessible, such as machining the inner bore or end faces of tubular workpieces.

Advantages of External Clamping:

• Uniform multi-point clamping around the OD

• Improved workpiece concentricity

• Reduced deformation caused by localized clamping

• Suitable for different tube diameters

• Allows easy access to the internal bore and end faces

 

Internal Expanding Clamping Solution

The collet expands outward against the inner diameter of the tube, providing uniform radial support along the internal surface of the workpiece.

This method is particularly suitable for thin-wall tubes, sleeve-type components, and applications requiring external diameter machining. It provides stable internal support while helping minimize workpiece deformation.

Advantages of Internal Expanding Clamping:

• Uniform internal diameter support

• Stable 360° radial clamping

• Reduced deformation of thin-wall tubes

• Improved stability for OD machining

• Suitable for high-precision cutting applications

 

Applications

• Metal tube machining

• Thin-wall tube machining

• Sleeve components

• Hollow shafts

• Automotive and motorcycle components

• Bicycle components

• Precision mechanical components

• CNC turning and mill-turn machining
