Marble plate Marble precision measuring tools, instrument platforms, also known as granite slab, using high quality ' Jinan Qing ' made by machining and hand-grinding stone. Black gloss, precise structure, texture, uniform, good stability, high strength, high hardness, can under the heavy load and the temperature accuracy and has no rust, acid and alkali resistance, wear resistance, not magnetic, type and so on.

Granite inspection plate/platform By its material effect, physical sex stable, organization careful, by impact grain off, surface not up Flash, not effect its plane precision, material stable, can guarantee long-term not deformation, line expansion coefficient small, mechanical precision high, rust, antimagnetic, insulation; granite test platform particles delicate uniform, structure stable, work surface in using in the maintenance maintenance simple, material stable, can guarantee long-term not deformation; granite test platform not by thermostat conditions block, temperature deformation small, precision keep performance good, To maintain measurement accuracy at room temperature. Measurements can be moved smoothly, without the creaky feeling, not under the influence of wet, flat good stability.

Use a marble platform considerations
1. marble platform was installed before use, ensure that debug level, and then wipe dry with a clean soft cloth and polishing or with sticky alcohol cotton sheet surface wipes clean, keep the table clean to prevent affecting the measurement accuracy.
2. the workpiece should be gently placed on a marble platform, when in use, to avoid impact, causing deformation and damage of the platform.
3. the weight of the workpiece for the rated load, or reduce the quality of work, damage the flat structure, resulting in deformation of the plate.
4. the measurements used in the workpiece gently, don't move crude artifacts on the platform, lest this bump platform surface, scratches and other damage.
5. the test piece and related measurement tools available at the plate for 35 minutes to adapt to the temperature measurement.
6. after the conclusion of the workpiece to be won from the platforms, avoid prolonged heavy pressure on the marble slab, must clean after each use clean the debris may stay above. will wipe clean surface (can be cleaned with neutral detergent) and covered with protective cover.
7. less marble platform should be placed in the dust, vibration-free and stable temperature, ventilation used in a dry environment.
8. do not place other items on a marble platform, prevent strokes, collisions, concentration of detergent used medical alcohol 75% alcohol, avoid using strong corrosive liquids as detergents.
9. move marble platform position, gently, to refit the level.

Small size marble platform maintenance: If the specifications of marble slab is relatively small, you can use three plates to repair the grinding method.

Large marble platform (flat) maintenance: If the bigger marble slab, you can use a 00 cast iron plate to grinding. When the grinding, to smear on the flat grind sand and conditioning oils, then 8 method of repairing, make sure you do.

Marble platform (flat) repair grinding process: in grinding Shi, marble flat and grinding flat middle into Emery or other grinding agent Hou, by Emery extrusion, marble flat surface produced rupture, dang grinding flat and marble flat relative movement Hou, due to abrasive of not rules and it in grinding disc and marble flat surface scroll, marble flat surface rupture of pieces and mill create of pieces was ' push go ', so repeat, gradually makes marble flat surface became smooth and precision of plane. Depending on whether the lapping abrasive using fluid, can be divided into wet grinding and dry grinding. Advantages of marble slab with wear-resistant without deformation, in daily use in the process, we should pay attention to maintenance, minor use, and thereby to increase plate life saving costs!
