Tolerance accuracy

Tolerance accuracy

We guarantee high surface accuracy & low deformation

The surfaces of tooling plates, measuring plates, marking plates and surface plates are produced in accordance with DIN 876. The plates are laid onto at least three support points in order to measure their surface accuracy. The plate ribbing designed for each application transfers the forces that occur during use into the support points to ensure that the deformation of the surface to be measured is correspondingly low and the surface accuracy is correspondingly high.

Flatness tolerances:

The flatness tolerances indicate the permissible deviation of the measuring area in μm over the entire length L of the longest edge of the plate at a reference temperature of 20 °C.

  • DIN 876 /III = 40 + L : 25 = µm
  • DIN 876 /II = 20 + L : 50 = µm
  • DIN 876 /I = 10 + L : 100 = µm
  • DIN 876 /0 = 4 + L : 250 = µm
