In this application,
the AUTOGRIP AP-375 large
thru-hole air chuck is installed on a MYDAY Machinery CNC precision
oil-tube lathe to support heavy-duty tube machining.
The system utilizes a dual-chuck
configuration, where the front and rear chucks work in sequence
to ensure secure clamping during machining of long oil tubes.
The oil tube is fed from the rear side and the extended tube is supported by a rear hydraulic steady rest, allowing stable machining of long and heavy workpieces.
Solution Features
- Large Thru-Hole Pneumatic Chuck Design
The AP-375 integrates an internal air cylinder to deliver stable and high clamping performance.It's large thru-hole design is ideal for processing long tubes, oil pipes, and both hollow or solid bar materials. - Built-in Pressure Monitoring Mechanism
The chuck incorporates an internal pressure-sensing mechanism that detects abnormal pressure drops, ensuring operational safety and preventing accidental workpiece slippage during machining. - AUTOGRIP Patented air supply system
The patented air-supply design eliminates the need for conventional sealing rings, significantly reducing installation time and avoiding seal-ring failure issues—ultimately lowering maintenance and machine downtime costs. - Compatible With C-Axis Positioning
When combined with machine C-axis positioning, the clamping sequence achieves accurate alignment and ensures stable, repeatable machining operations.
Machining Benefits
By implementing this dual-chuck clamping setup with steady-rest support, the customer achieved:
- Higher machining efficiency
- Reduced time for manual refixturing and repositioning
- Improved operational safety
- Stable long-duration machining performance
This application demonstrates AUTOGRIP’s expertise in automated tube-machining clamping
solutions, helping customers enhance productivity and maintain
high accuracy in demanding oil-tube machining processes.
