Royal Mandrel Model E – 47104

• Mandrel models are defined by their gripping range.
• Expanding rod, expanding rod adapter, and mounting hardware included with each mandrel.
• Order expanding sleeves separately.

ID gripping is often overlooked as a workholding option, yet in many situations it is the best choice:

• 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, ID gripping on the second spindle eliminates the risk of surface damage that can be caused by second-op OD gripping of a previously-turned diameter.
• For many parts, the engagement-length of an ID bore can be greater than what is available for OD gripping, resulting in superior rigidity and torque transmission.
• ID systems tend to be more streamlined than OD systems, enabling better part access especially important for use on machines with live tooling

How to Order:

1. Choose the appropriate body assembly based upon the lathe spindle it will be mounted to. Just like with Royal CNC Collet Chucks, each ID gripping system includes a custom-machined drawtube connector to ensure hassle-free installation.
2. Choose the appropriate mandrel based upon the diameter you plan to grip. All mandrels and bodies share a common mounting interface for full interchangeability. Each mandrel includes the expanding rod and an expanding rod adapter.
3. If required, choose part locator to provide a banking surface for the workpiece.
4. Choose the appropriate expanding sleeve based upon the diameter you plan to grip.
