Marble platform Handling Precautions

My company make correct use of operating Everbright marble platform, the following special finishing; marble platform Description: Precision Reference of natural stone materials measuring tool, it has structural precision, even texture, good stability, strength , high hardness, high accuracy can be maintained under heavy duty and general temperature, and has no rust, acid, wear resistance, is not magnetized, the same type, etc., of the instruments, precision tools, machinery and parts inspection, is an ideal plane, particularly for highly accurate testing. Marble platform Physical properties: Dimensions: L200 * W300 * H150mm-L4000 * W2000 * H400mm; specific gravity: 2970 ~ 3070kg / m3; compressive strength: 245 ~ 254N / mm2; elastic grinding amount: 1.27 ~ 1.47N / mm2; line expansion coefficient: 4.6 × 10 ~ 6 ℃; Water absorption: 0.13%; Shore Strength: Hs70 above. Flatness tolerance by: GB4987-85 standard 000 = 1 × (1 + d / 1000) um, 00 级 = 2 × (1 + d / 1000) um, 0 级 = 4 × (1 + d / 1000) um grade 1 = 8 × (1 + d / 1000) um; measured temperature is generally 20 ± 2 ℃. Marble platform: 1, the need to marble platform debugging level before using; 2, with sticky cotton alcohol wipe board; 3, will be measuring the workpiece and the associated measuring instruments placed on the marble platform 5 to 10 minutes until the temperature adaptation After the measurement can be carried out; 4, after the measurement is complete, wipe clean the board and close the shield. Notes: 1. Do not strike, collision marble platform; 2, do not place other items on the marble platform; 3, move the marble platform position, re-commissioning the levelness; 4, when placed marble platform to choose low noise , less dust, no vibration, temperature stable environment.
