A0 | Blind-Hole Expanding Mandrel
The TOP-TOOL A0 Blind-Hole Expanding Mandrel is designed for internal expansion clamping of blind-hole or semi-through-hole workpieces where outside clamping is not suitable.
This expanding mandrel supports internal clamping from the bore side and is selected according to the workpiece bore, clamping range and locating requirements.
Key Features
- Segmented clamping provides broad contact around the workpiece.
- Suitable for workpieces requiring stable, repeatable and surface-sensitive clamping.
- Different series support through-hole, blind-hole, inner-stop, expanding, air-operated, accessory and multi-spindle applications.
- Model selection is based on clamping range, chuck size, mounting method and repeatability requirement.
Typical Applications
- Round, square or hexagonal workpieces
- Thin-wall or surface-sensitive parts
- Workpieces requiring broad contact clamping
- Repeat CNC workholding applications
- Applications where jaw marks or point contact should be reduced
- Expanding mandrel setup, changeover or preparation workflows where applicable
Selection Notes
- Confirm the workpiece shape and clamping diameter.
- Check whether the application requires through-hole, blind-hole, inner-stop, expanding, air-operated or multi-spindle clamping.
- Review clamping range, mounting method and repeatability.
- Confirm whether a chuck assembly, replaceable segmented clamping bushing element or supporting tool is required.
- Send the workpiece drawing and machine information for technical review before ordering.
