Granite measuring plate 630x630x100mm, accuracy DIN876 / 00, Accurata

Plain granite

Size: 630x630 mm
Precision: 00

DIN876, resp. DIN876 / 00

Classification of granite plates according to DIN876, where L is length in mm:
00: 2 L / 500 µm
0: 4 L / 250 µm
1: 10 L / 100 µm
2: 20 L / 50 µm

The plate meets the given accuracy according to DIN876 and is manufactured according to more demanding production tolerances - see below. Practically, it has an even more accurate planarity than standard DIN876.

Production tolerances of granite slabs where L is length in mm:
000: (0.003 x L 2.5) / 4 um
00: (0.003 x L 2,5) / 2 um
0: (0,003 x L 2,5) um
1: (0,003 x L 5) um

Advantages of Granite Plates:
1. High precision, shape and dimensional stability under standard temperature conditions
2. No rust
3. Extremely abrasion-resistant black granite guarantees long service life. Any scratches, scratches or similar accidents during use of black granite products do not cause "material strain" and do not affect the accuracy of
5. Non-magnetic
6. Up to the mirror-smooth surface allows smooth movement of the measured part or gauge during the measurement
