Granite Calibration Plate With Size 2000 x 3000 x 300 mm


The hardness and stability allow accuracies within millionths of an inch. Along with the high accuracies, granite is rust-proof, non-magnetic, abrasive resistant, non wedging, wrap-resistant and easily cleaned. The granite used for surface plates has an excellent distribution of hard quartz which provides a smooth, long-wearing working surface.
Granite surface plates meet or exceed Federal Specifications DIN/876. Final inspection and calibration of every surface plate is accomplished by use of the Auto-Collimeter
Repeatability:

  • Grade "B" Toolroom ± 100 Millionths
  • Grade "A" Inspection ± 50 Millionths

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
