CMM Plates

CMM base plates: The HOLE advantage. Multiple threaded holes on the R&R Fixture base plate help increase the flexibility of your fixture.

Our base plates have been engineered out of cast aluminum with a hard coat anodize coating called Ni-Tuff™. With its Teflon makeup and extra penetration of the hard coat it has proven to be more durable and to resist scratches. Base plates can also be made of steel with a black oxide finish.

Easy Installation

If needed mounting holes are included for attaching the R&R Fixture base plate to your CMM. A drawing will be provided from R&R showing the exact location of the fixture base plate on your specific CMM as well as the mounting hole positions.

  • Plates are available in sizes from 6.0" x 6.0" (150mm x 150mm) up to 60" x 120" (1500mm x 3000mm) in a single fixture plate.
  • For even larger applications we can use multiple plates to create any size.
  • Ask about our plates ready to ship.
  • Custom base plates to fit your application and CMM available at no extra charge.
  • Base plates more than 30" x 30" (750mm x 750mm) are numbered in both the X and Y direction. Plates less than 24" x 24" (600mm x 600mm) are labeled with letters in the X and numbers in the Y unless specified.
