Granite measuring plate 300x200x50mm, accuracy DIN876 / 00, Accurata

Average granite slab

Size: 300x200 mm
Accuracy: 00

Standard: DIN876, resp. DIN876 / 00

Class accuracy granite slabs according to DIN876, where L is length h mm:
00: 2 L / 500 um
0: 4 L / 250 um
1: 10 L / 100 um
2: 20 L / 50 um

The board therefore meets the given accuracy according to DIN876 in addition it is manufactured according to demanding production tolerances - see below Practically has therefore even more exact flatness than indicates standard DIN876.

Production tolerances granite slabs, where L is length h 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

Benefits granite slabs:
1 High accuracy, shape and dimensional stability under standard temperature conditions
2. none rust
3. Highly abrasion-resistant black granite guarantees long life
4. Any jam, scratch es or similar accidents during use products of black granite do not cause "rolling of material" and do not affect accuracy
5. Non-magnetic
6. As mirror image smooth surface allows smooth movement measured part or gauge during measurement
