ROYAL POWER-BLOCK™ I.D. WORKHOLDING
For Milling Applications
- The Royal Power-Block™ I.D. Workholding System enables secure gripping on the internal bore of a workpiece for full external machining access.
- Pullback action draws workpiece securely against a ground locator for precise, consistent z-axis positioning.
- Unit can be mounted to a traditional machining center table and can also be used in 4th and 5th-axis applications.
- Fixture is designed to be actuated via hydraulic pressure and may also be actuated pneumatically for lighter-duty applications (contact us for details).
- For use with all Royal precision mandrels, stops, and sleeves. These items are sold separately.
- Heavy-duty all steel construction with a large double-acting piston provides high clamping force.
- Configured with both side and bottom ports for plumbing flexibility.
- Multiple units can be plumbed in series for single-source actuation.
- Ideal for high-production applications on vertical, horizontal, and five-axis machining centers.
- Tombstone and angle plate compatible.
How to Order:
- Choose the appropriate body assembly based upon your application.
- Choose the appropriate mandrel (models A-E) based upon the diameter you need to All mandrels and bodies share a common mounting interface for full interchangeability.
- If required, choose the appropriate part locator to provide a ground banking surface for the workpiece.
- Choose the appropriate expanding sleeve based upon the mandrel and diameter you need to grip.

Step 4 - Choose Expanding Sleeve
- Order expanding sleeves according to mandrel models A thru E.
- All expanding sleeves are fully sealed against coolant and chip penetration.
- Parallel grip ensures full-length part contact for optimum accuracy and grip force.
- All sleeves collapse 0.005" below nominal ground size to ensure easy part loading and unloading.
- Order body assembly, mandrels, and locators separately
Royal Expanding Sleeves - Model A
Royal Expanding Sleeves - Model B
Royal Expanding Sleeves - Model C
Royal Expanding Sleeves - Model D
Royal Expanding Sleeves - Model E
*Not sealed due to limited wall thickness.
Note – sleeves larger than 2-1/2" dia. are 0.28" longer than dimension E and terminate flush with the face of the expanding rod.
