Granite measuring plate 150x150x40mm with M8 thread, accuracy DIN876 / 00, Accurata

Average granite plate, with M8 thread

Size: 150x150 mm
Accuracy: 00

Standard: DIN876, resp. DIN876 / 00

Accuracy classes of granite slabs according to DIN876, where L is the length in mm:
00: 2 L / 500 um
0: 4 L / 250 um < br> 1: 10 L / 100 um
2: 20 L / 50 um

The board therefore meets the given accuracy according to DIN876 and in addition it is manufactured according to demanding production tolerances - see below. In practice, therefore, it has an even more accurate flatness than the DIN876 standard.

Production tolerance of granite slabs, where L is the 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

Material: top quality Black granite from granite mine - natural granite
Specific gravity: 2970-3070kg / m3
Strength: 245-254 MPa > Flexibility: 120-127 GPa
Coefficient of expansion: 4.61 x 10-6 / Â ° C
Water absorption: <0.07%
Hardness in Shore: over 70Hs

Advantages of granite slabs:
1. High accuracy, shape and dimensional stability under standard temperature conditions
2. No cut
3. Highly abrasion resistant black granite guarantees a long service life
4. Any jams, scratches, or similar accidents while using black granite products do not cause "rolling out of the material" and do not affect accuracy
5. Non-magnetic
6. Until the mirror-smooth surface allows the smooth movement of the measured part or gauge during the measurement
