Royal CNC Expanding Mandrels
Body Assemblies
- The body provides a precision interface for connecting the mandrel to the lathe spindle.
- Assembly includes body, custom-machined drawtube connector, and mounting hardware.
Mandrels
- Mandrel models are defined by their gripping range.
- Expanding rod, expanding rod adapter, and mounting hardware included with each mandrel.
Part Locators
- Part locators are an optional accessory.
- Locator bolts to the front of the mandrel and provides a square surface for the workpiece to locate against.
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:
- 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.
- 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.
- If required, choose part locator to provide a banking surface for the workpiece.
- Choose the appropriate expanding sleeve based upon the diameter you plan to grip.
