Test Angle K1

The test angle K1 has two even measuring surfaces, arranged orthogonal to each other. The measuring surfaces are lapped finely and in highest accuracy. The accuracies are, depending on the customer demand, between DIN 876/00 (4 µm at L 1000 mm) and DIN 876/00000 (0.5 µm at L 1000 mm).


Important: At our test angles also the side faces are processed. They match geometrically to the measuring surfaces, so that the angle is also while lying truly correct.
