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.

The marble terrace (flat) the repair of 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, thereby to increase plate life saving costs! Yongjun gauge master trained a group of professional straight measuring tool maintenance, year-round maintenance of various marble platform, cast iron plate, guide, my company sells measuring only charge a simple fee.

Its accuracy is divided into: 000, 00, 0,

The marble terrace Is made with natural stone material base of precision measuring tools, instrumentation, precision tools, mechanical parts inspection, is the ideal base, marble platform, especially for high precision of measurement. The marble terrace Based on high quality underground rock, after millions of years of natural aging, morphology is extremely stable, without fear of deformed because of the temperature difference between the conventional. Granite slab After rigorous physical tests and selection of granite, Crystal fine, hard. Marble, because of non-metallic materials, and no magnetic response, there is no plastic deformation. Granite slab to its high hardness, good accuracy. Principal mineral composition pyroxene, plagioclase, and a few olives, biotite, and trace amounts of magnetite, black gloss, structural precision, I plant a marble slab, marble platform, using high quality ' Jinan Qing ' natural marble material machined, hand lapping. Black gloss, precision homogeneous structure, good stability, high strength, high hardness. Well under heavy load and the temperature generally remains stable. The marble terrace Is made with natural stone material base of precision measuring tools, instrumentation, precision tools, mechanical parts inspection, is the ideal base, especially for high precision measurement. After rigorous physical tests and selection of marble, Crystal fine, hard. Marble, because of non-metallic materials, and no magnetic response, there is no plastic deformation. Its high hardness, good accuracy. In use tool even when the load of rock bump, up to a few grains of ballast. Its superior high quality precision measuring parts made of cast iron and steel, you can get high and stable precision. 00'-level marble slab, marble platform, after a year of use, can still maintain the original precision constant.
