250 mm Ball Lock Hydraulic Chuck
The TOP-TOOL 250 mm Ball Lock Hydraulic Chuck is a specialized hydraulic workholding solution for CNC lathe applications involving long shafts, center-supported workpieces and setups where support, alignment and clamping stability must be considered together.
This is not a general lock component. It is a hydraulic chuck structure selected for specific workholding applications where a standard hydraulic chuck cannot provide the required support or alignment control.
Key Features
- Special chuck structure for applications where support and alignment are important to the clamping process.
- Suitable for long workpieces and center-supported parts.
- Hydraulic actuation for CNC lathe workholding setups.
- Selected according to the actual workpiece drawing and support method.
- Designed for specific workholding problems rather than general locking hardware applications.
Typical Applications
- Long shaft workpieces
- Center-supported parts
- Alignment-sensitive CNC lathe workholding
- Special hydraulic chuck applications
- Workpieces requiring additional support during clamping
Selection Notes
- Confirm the workpiece length, support method and clamping position.
- Check whether the part requires center support or special alignment control.
- Review jaw stroke, clamping force and maximum speed.
- Check the machining process and cutting load.
- Select the chuck according to the workpiece drawing and support method.
