Three-coordinate platform, also known as a three-coordinate flat plate, cast iron three-coordinate platform, marble three-coordinate platform, cast iron flat, cast iron platform
Three-coordinate platform material: high-strength cast iron HT200-300, with a working surface hardness of HB170240, and has been through two manual treatments (manual annealing at 600-700 degrees and natural aging for 2-3 years), precision of this product is stable and has good wear resistance.
Specifications and parameters
Size of the three-coordinate flat plate: 100100—3000600, (Special sizes are made according to the drawings of the customer.)
Accuracy of the three-coordinate flat plate: It is carried out according to the standard metrology inspection procedures, which are divided into four levels: 0, 1, 2, and 3. The accuracy of the three-coordinate platform is relatively. After the flat plate casting is finely processed by the machine tool, it still needs to be manually scraped and polished to achieve the required accuracy. The general accuracy standard:
Inspection standard: Inspection by color coating method.
For the 0th and 1st grade flat platforms, there should be no less than 25 in each 25㎜ square range on each side.
For the 2nd grade flat platform, there should be no less than 20 points in each 5㎜ square range on each side.
For the 3rd grade flat platform, there should be no less than 12 points in each 25㎜ square on each side.
