Three coordinate tablet

The three coordinate flat panel is suitable for various three coordinate inspection and measurement work, as well as machine tool mechanical inspection and measurement benchmarks; Check the dimensional accuracy or shape deviation of the parts, and attach three markings on the surface for easy three-dimensional measurement. On flat working surfaces with precision levels below level 00, sand holes with a diameter less than 15mm are allowed to be plugged with the same material, and their hardness should be lower than that of the surrounding materials. The number of blocked areas on the working surface should not exceed four, and the distance between them should be greater than 80mm. Three coordinate flat working surfaces should use scraping technology, and for level 3 flat working surfaces, scraping technology can also be used. The surface roughness of the scraped working surface should not exceed 5um according to the arithmetic mean deviation Ra value of the contour. The flat surface should undergo stability treatment and demagnetization treatment.

After manual annealing at 600-700 degrees and natural aging for 2-3 years, the accuracy is stable and the wear resistance is good. Reasonable maintenance of flat plates: Scratching and grinding contact spots can extend the service life of flat plates. Due to the rough surface of solids, the surfaces of two objects always come into contact at individual points, so the actual contact area is much smaller than the theoretical contact area. Because the actual contact surface is small, even under low loads, a large unit pressure will be generated. Due to different surface roughness, the wear of the contact surface varies with the frictional force under unit pressure. Factors such as the material, hardness, environment, and maintenance of the three-dimensional flat plate can also have different effects on the wear of the scratch contact spot.

The specifications of the three coordinate tablet range from 100 * 100 to 3000 * 6000, and those larger than this specification can be assembled and used or customized according to the drawings.

Three coordinate flat panel accuracy: According to the national standard metrological verification regulations, it is divided into four levels: 0, 1, 2, and 3.
