T-Slots

T-slots are manufactured according to DIN 650-H12 as standard. A higher accuracy in the tolerance field H7 or H8 is also possible. Special dimensions of T-slots on request.

Surface accuracy - Tolerances

The surfaces of clamping, measuring, marking and spotting plates are manufactured according to DIN 876. To measure the surface accuracy, the plate is placed on at least three points. The ribbing of the plate, designed for the respective application, diverts the forces occurring during use to the support points so that the deformation of the surface is correspondingly low and the surface accuracy correspondingly high.

Flatness tolerances

The flatness tolerances indicate the permissible deviation of the measured surface in µm over the entire length L of the longest edge of the plate. Reference temperature 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
