Used in the machine and tool inspection, manufacturing and repair of mechanical equipment benchmark natural rock work platform, versatility is relatively strong, processing margin is very small, very high precision, uniform texture, good stability, high strength, high hardness, To maintain high precision, used in industrial production and laboratory measurement work.

Marble platform / granite plate (1 + d / 1000) um, 00 grade = 2 × (1 + d / 1000) um, 0 level = 4 × (1 + d / 1000) um, 1000) um, 1 = 8 × (1 + d / 1000) um (d is diagonal mm) (measured temperature is generally 21 ± 2 ℃).

Marble platform / granite plate Specifications: 200 × 200-2000 × 4000mm (special specifications according to the needs of the drawings can be made slotted drilling sets of braces).

Granite test plate / platform It can not guarantee the long-term deformation, the linear expansion coefficient is small, the mechanical precision is high, the rust-proof, the rust-proof, the rust-proof, the rust-proof, the rust-proof, Magnetic granite test platform particles fine and uniform, stable structure, the working surface in the use of maintenance and easy maintenance, material stability, to ensure long-term deformation; granite test platform is not subject to constant temperature conditions, the temperature difference is small, precision Maintain good performance, at room temperature can also maintain the measurement accuracy. Measurement can be smooth movement, no lagging sense, not affected by moisture, good plane stability.

Marble inspection and measurement platform The marble platform is made of high quality rock layer, after hundreds of millions of years of natural aging, the shape is extremely stable, do not worry about the deformation due to the conventional temperature difference. Strict physical test and selection of granite material, crystal fine, hard texture, compressive strength of 2290-3750 kg / square centimeter, the hardness of Mohs hardness of 6-7. Extremely resistant to wear, acid, alkali, High corrosion resistance, never rust. As a result of marble non-metallic materials, no magnetic reaction, no plastic deformation. Its hardness 2-3 times higher than cast iron (equivalent to HRC> 51)

000 marble platform surface for machine tool grinding, in the artificial grinding, usually divided into coarse grinding, semi-fine grinding, fine grinding, grinding and polishing five processes to complete the production.

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

Large size marble platform (flat) maintenance: If the specifications of the marble plate is large, you can use a 00 grade cast iron plate to grind it, with a digital level meter in the grinding, the first flat on the application of grinding sand and conditioning oil, and then 8 words Repair, can reach the unimaginable precision.

Marble platform (flat) repair grinding process : In the grinding, the marble plate and the grinding plate into the middle of the corundum or other abrasive, the crushed by the diamond, the marble plate surface rupture, when the grinding plate and the marble plate relative movement, due to abrasive irregular and it in the grinding The discs are rolled on the surface of the marble plate, the broken pieces of the marble plate surface and the pieces of the abrasive are pushed away, so that the surface of the marble plate becomes gradually smooth and precise. According to whether the abrasive is polished , Can be divided into wet grinding and dry grinding. Marble plate with wear and tear without deformation of the advantages of the daily work in the use of the process, we should pay attention to maintenance, use, so that can extend the life of flat and cost savings! Training a group of professional straight gage maintenance master, perennial maintenance of a variety of marble platform, cast iron plate, machine tool guide, the company sold the measuring tool only charge a simple fee.

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

Marble platform with high strength, high hardness, no rusty acid and alkali, no magnetization, the same type, good wear resistance, etc. Compared with the cast iron plate is not easy to change, put a year later, still able to maintain the original accuracy of the same The most important is the good wear resistance and other advantages in the heavy load and the general temperature to maintain stability. The original marble platform has so much effect ah! Really good!
