Granite Surface Plates

Posted by Michael Wood on

Looking for accurate precision equipment and measuring software can be a tough job especially without appropriate knowledge and sources about these things. Hence, in order to cater to the needs of our customers along with the general public, GreatGages.com offers a great deal of precision measuring devices, data collection software, and shop equipment like Granite Surface Plates.

Often we find that the proper precision measuring process begins with a stable, flat surface to perform your measurements on. Granite is one of the best materials available today to meet the ever changing and sophisticated applications demanding coplanarity, perpendicularity, parallelism, flatness, and straightness, but it is most often chosen for its stability and high accuracies. With the Granite Surface Plates we offer, you can depend on excellent quality, high accuracies, and quick delivery.

Our Granite Surface Plates are made of black granite which is stronger and denser than light colored granite, and more stable. The granite properties determine the stiffness of the granite so accuracies can be guaranteed with less thickness than other types of granite. This translates to less freight and handling whenever the plate is shipped or moved.

Our Granite Surface Plates are available in 3 different grades…

  • AA Grade (Laboratory Grade)
    • High precision operations in temperature controlled gauging rooms and metrology departments
  • A Grade (Inspection Grade)
    • General Quality Control Use
  • B Grade (Toolroom Grade)
    • ShopWork and Production Checking

Ledges for Clamping

Most people think of Granite Surface Plates as having straight, flat sides. That is the standard 0-Ledge Granite Surface Plate. Most of our Granite Surface plates also are available with shorter, notched-out sides that allowing for clamping of products to the granite.

Granite Surface Plates Ledges are described as follows...

  • 0-Ledge
    • Standard, flat sides
  • 2-Ledge
    • Shorter sides on the left and right sides only
  • 4-Ledge
    • Shorter sides on the left and right as well as front and back
