Royal Power-Block™ I.D. Body Assembly

Royal’s line of I.D. Workholding Systems provides a wide range of off-the-shelf solutions for many common turning, milling, and grinding applications.

Our unique modular design covers a standard gripping range from 0.5” to 3.25”, with specials available up to 25”. Sleeves offer parallel expansion for maximum rigidity, and accuracy is guaranteed to ± 0.0005” TIR.

I.D. Workholding Advantages:

• Allows for full access to the entire length of the workpiece so all external diameters can be turned in a single operation, guaranteeing perfect concentricity.
• On sub-spindle machines, I.D. gripping on the second spindle eliminates the risk of surface damage that can be caused by second-op O.D. gripping of a previously-turned diameter.
• For many parts, the engagement-length of an I.D. bore can be greater than what is available for O.D. gripping, resulting in superior rigidity and torque transmission.
• I.D. systems tend to be more streamlined than O.D. systems, enabling better part access – especially important for use on machines with live tooling.

Royal Power-Block™ I.D. Body Assembly

• 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 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 Royal for
  details).
• For use with all Royal precision mandrels, stops, and sleeves.  Please order 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.
