Standard Specification for normal operation of marble mechanical components

Marble mechanical components are manufactured by using the characteristics of granite, which are used to measure the accuracy of parts in industrial production

marble mechanical components are generally used for inspection, marking and assembly of workpieces. The production process is the same as the marble platform, which is made of mechanical processing and manual grinding, but the process of marble mechanical components is much more complex

marble mechanical components are used for tooling in the machinery industry, so they are called granite mechanical components or marble mechanical components. The characteristics of marble mechanical components are basically the same as that of granite platform. Maintenance process and standard of S & P granite components: the production and inspection of S & P granite components are completed in accordance with the measurement standard

Natural granite is used as raw material for marble mechanical components. Such advantages are not easy to wear, good hardness, not easy to deform, convenient maintenance and stable precision. The original grinding process used for the maintenance of marble mechanical components uses emery as the raw material, 300 * 400 small platform as the grinding tool, and digital display level as the inspection standard

the purpose of fine grinding of marble mechanical components is to further precision the flatness of semi fine grinding to the basis of precision. The fine grinding of marble inspection mechanical components with precision shall be carried out manually. The intention of fine grinding is to further grind the marble inspection mechanical components with precision directly to the required precision. The marble inspection mechanical components that have reached the standard accuracy after careful grinding are polished. The polished marble inspection mechanical components have smooth surface, not easy to wear, high plane roughness value and stable accuracy. The marble mechanical components are completed. First, rough grind the marble inspection mechanical components that need to be repaired. The purpose of rough grinding is to rough grind the thickness and flatness of the marble inspection mechanical components under the standard. The rough ground marble mechanical components are subjected to secondary semi-fine grinding. The purpose of semi-fine grinding is to reach the standard flatness after removing deep scratches. After the initial adjustment is qualified, it shall be copied after standing for 12 hours. If it is unqualified, it shall be adjusted again. If it is qualified, it can be used

standard description of normal operation of marble mechanical components:

1. Do not place other items on marble mechanical components, do not knock or bump marble mechanical components, and use alcohol with a concentration of 75% ethanol as detergent. Avoid using liquid with severe corrosion as detergent

2. When moving the orientation of marble mechanical components, it is necessary to re adjust the levelness

3. Clean the sundries that may be left on it after each use; Scrub the board surface clean (it can be cleaned with neutral detergent) and cover it with protective cover

4. When repeatedly measuring the accuracy of the same workpiece, it should be selected in the same period when the temperature is stable

5. The weight of the workpiece shall not exceed the rated load of the plate, otherwise it will drop the operation, and may damage the structure of the plate, form the deformation of the plate and cannot be used

6. Marble mechanical components shall be placed in a dry and ventilated environment with low noise, less dust, no vibration, stable temperature

7. After use, in order to avoid the overall deformation of marble mechanical components, the workpiece should be removed from the mechanical components to avoid the long-term heavy pressure of the workpiece on the granite plate and form the deformation of marble mechanical components

8. The mechanical components shall be cleaned in real time, and the marble mechanical components shall be cleaned when not necessary. Then apply a layer of antirust oil on the surface of mechanical components and all steel parts on the surface, cover it with antirust paper and cover it with the outer package of marble mechanical components, so as to avoid the damage to granite flat plate caused by carelessness

9. In the process of application, the workpiece on the marble mechanical component shall be handled with care, and the rough workpiece shall not be moved on the mechanical component, so as to avoid bumping, scratching and other damage to the surface of the mechanical component

10. The workpiece shall be placed on the marble mechanical components slowly, and the marble mechanical components shall not be used. Avoid the mechanical components of Dali from being hit, forming the deformation and damage of mechanical components

11. Place the workpiece to be measured and relevant measuring tools on the flat plate for 35 minutes, and measure after the temperature is used to it
