Round & Circular Grid Plates
Grid plates are developed as a low-profile CNC subplate equipped with a precision, alphanumeric 2” grid pattern. Installed directly to your CNC machine table, these grid plates are made to meet the tightest industry tolerances and are equipped for use with any 2” compatible workholding system.
Key Features
- Grid holes, bushings, and inserts are available for both 1/2" and 5/8" systems
- Hardened, threaded inserts allow for clamping in every hole while offering quick and easy replacability
- Hardened, precision bushings are accurately located to ensure easy locating coupled with high wear resistance
- Replacement bushings and insert kits with an extraction tool are available upon request
CAD Downloads: CAD download is for a plain face grid plate, all measurements are in inches unless otherwise noted, all weights are in pounds.
Grid plates are also known as: Tooling Plates, Sub Plates, or Locator Plates.
