1. High precision, good stability, and not easily deformed. Can ensure measurement accuracy at room temperature.

2. No rust, acid and alkali resistant, no need for special maintenance, good wear resistance, long service life.

3. Scratches and bumps on the work surface do not affect measurement accuracy.

4. During measurement, it can slide smoothly without any discomfort.

5. The characteristics of marble components are abrasion resistance, high temperature resistance, and maintenance. Physically stable, meticulously organized, with grain detachment upon impact, no burrs on the surface, and no impact on its flatness accuracy. Granite precision measurement flat plate. Rocks undergo long-term natural aging, with uniform organizational structure, extremely low coefficient of linear expansion, disappearance of internal stress, and no deformation.

The working surface of marble components is easy to maintain during use, with stable material that can ensure long-term deformation, low coefficient of linear expansion, high mechanical accuracy, rust prevention, demagnetization, and insulation. No deformation, high hardness, strong wear resistance.

Mechanical Assembly

To ensure the quality of the assembly of stone machinery products, it is necessary to operate in accordance with the prescribed technical requirements for the assembly of various stone machinery products. Although the assembly technology requirements for different stone machinery products may vary, in the assembly process There are many key work points that must be jointly adhered to in the contract.

1. Cleaning and cleaning of good parts. The cleaning work includes removing residual casting sand, rust, chips, etc. Especially some important components, such as gantry cutting machines and inner chambers, should be coated with anti rust paint. Oil stains, rust, or attached chips on the parts can be cleaned with diesel, kerosene, or gasoline as a cleaning solution, and then dried with compressed air.

2. Lubricant is usually added to the matching surface before fitting or connecting. Especially the bearing parts in the spindle box components,lifting mechanismThe screw nut part.

3. The fitting dimensions of matching parts should be accurate, and the fitting dimensions should be rechecked or sampled during assembly. For example, the mating area between the journal of the spindle and the bearing, the hole and center distance between the spindle box and the bearing.

4. The assembly of the wheel requires that the axis lines of the two meshing wheels must be in the same plane and parallel to each other, ensuring normal meshing clearance and axial misalignment ≤ 2MM.

5. The joint surface of the connection should be checked for flatness and deformation, otherwise it should be trimmed, deburred, and ensured that the joint surface is in close contact, flat, and not skewed.

6. The sealing element should be pressed parallel into the sealing groove, without twisting, deforming, damaging or scratching the sealing surface.

7. The assembly requirements for pulleys are that the axes of the two pulleys must be parallel, and the center of the pulley groove should be aligned. If the offset is too large, it will cause uneven tension in the pulleys, resulting in belt slippage and accelerated wear. At the same time, the triangular belt should be selected before assembly, and the length should be consistent to prevent vibration during transmission.

8. The bearings should be cleaned before assembly, and the anti rust paint should be removed before assembly; When cleaning, attention should be paid to checking whether the raceway and rolling elements are corroded, and whether the rotation is flexible; When assembling bearings, a layer of lubricating oil should be applied to the surface of the mating parts. If a significant pressure difference is found during assembly, the assembly should be stopped for inspection; When assembling bearings, the end without a model should face inward, in the direction of the shaft shoulder; Do you apply more force when assembling bearings? The direction and position should be appropriate, and the rolling elements of the raceway should not be subjected to force. They should be evenly and symmetrically struck, and should not be hit hard, ensuring that the end face is perpendicular to the axis and preventing installation tilt.

9. Threaded connections should use anti loosening devices, and the following commonly used anti loosening devices should be selected according to the actual situation and design requirements; Double nut anti loosening; Spring washer anti loosening; Open mouth anti loosening; Stop washer anti loosening round nut and flower washer anti loosening; The symmetrical tightening method for multiple bolts should be gradually tightened in a symmetrical sequence, and strip connectors should be tightened symmetrically from the middle to both directions. The tail of the rib connected by bolts should protrude from the nut.

10. Perform assembly and inspection simultaneously.

11. Carefully carry out pre driving inspection work. For example, checking the integrity of assembly work, the accuracy and reliability of each connecting part, the flexibility of moving parts, and the normality of lubrication systems.

12. Carefully monitor the startup process. After starting the machine, immediately observe whether the main working parameters and moving parts are moving normally. The main working parameters include the speed of motion, smoothness of motion, spindle rotation, lubricating oil pressure, temperature, vibration, and noise. Only when all motion indicators are normal and stable during the start-up phase, can the trial operation be carried out.

13. Conduct trial operation and testing of relevant items according to the acceptance conditions of various stone machinery products. For example, adjustment and testing of cutting speed and stroke, adjustment of lifting motion stroke, testing of spindle rotation accuracy, etc.

Precision advantage

Marble components are precision reference measuring tools made of natural stone materials. Marble components aremarble slabIt's a line drawingA workbench is indispensable for measurement, riveting, welding, and tooling processes.

Marble components can also be used as mechanical test benchesSuitable for various inspection work, a reference plane for precision measurement, used as a benchmark for machine tool mechanical inspection and measurement, to check the dimensional accuracy or behavioral deviation of parts. It is favored by the mechanical industry and laboratories.

The characteristics of the on-site working environment and long-term maintenance of marble components are the accuracy of the product itself, better determination of the working environment, and the precision and quality of the processed and tested marble components.
