Product Description

Calibration Tools Granite Flatness Measurement Table

 

Granite Surface Plates are manufactured using natural black granite stone, quarried from earth in its natural form. These precision granite surface plates are precision lapped to high standards of flatness to achieve accuracy and are used as bases for mounting sophisticated mechanical, electronic and optical gauging systems. Our quality inspectors and engineers put a strict vigilance at all the stages of the production procedure to ensure high quality surface plates.

 

Some of the unique features of our granite surface plates are:

  • Uniformity In Hardness
  • Accurate Under Load Conditions
  • Vibration Absorbent
  • Easy To Clean
  • Rust-Proof, Non-Corrosive
  • Lower Coeffficient of Thermal Expansion
  • Warp Resistant
  • Low Porosity
  • Non-Abrasive
  • Non-Magnetic

 

Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:

 

Grade 000 =1x(1+d/1000)/μm

Grade 00 =2x(1+d/1000)/μm

Grade 0 =4x(1+d/1000)/μm

Grade 1 =8x(1+d/1000)/μm
