Granite components are widely used in precision machinery, measuring instruments, and laboratory applications due to their stability, rigidity, and resistance to corrosion. To ensure long-term accuracy and reliable performance, strict attention must be paid to assembly processes. At ZHHIMG, we emphasize professional standards during assembly to guarantee that each granite part performs at its best.
1. Cleaning and Preparation of Parts
Before assembly, all parts must be thoroughly cleaned to remove casting sand, rust, oil, and debris. For cavities or key sections such as large cutting machine housings, anti-rust coatings should be applied to prevent corrosion. Oil stains and dirt can be cleaned using kerosene, gasoline, or diesel, followed by compressed air drying. Proper cleaning is essential to avoid contamination and ensure accurate fits.
2. Seals and Joint Surfaces
Sealing components must be pressed evenly into their grooves without twisting or scratching the sealing surface. Joint surfaces should be smooth and free from deformation. If any burrs or irregularities are found, they must be removed to ensure close, precise, and stable contact.
3. Gear and Pulley Alignment
When assembling wheels or gears, their central axes should remain parallel within the same plane. Gear backlash must be properly adjusted, and axial misalignment should be kept below 2 mm. For pulleys, the grooves must be properly aligned to avoid belt slippage and uneven wear. V-belts should be paired by length before installation to ensure balanced transmission.
4. Bearings and Lubrication
Bearings require careful handling. Before assembly, remove protective coatings and check raceways for corrosion or damage. Bearings should be cleaned and lubricated with a thin layer of oil before installation. During assembly, excessive pressure should be avoided; if resistance is high, stop and recheck the fit. The applied force must be directed correctly to avoid stress on rolling elements and ensure proper seating.
5. Lubrication of Contact Surfaces
In critical assemblies—such as spindle bearings or lifting mechanisms—lubricants should be applied before fitting to reduce friction, minimize wear, and improve assembly precision.
6. Fit and Tolerance Control
Dimensional accuracy is a key factor in granite component assembly. Mating parts must be checked carefully to ensure compatibility, including shaft-to-bearing fits and housing alignment. Re-verification is recommended during the process to confirm precise positioning.
7. Role of Granite Measuring Tools
Granite components are often assembled and verified using granite surface plates, granite squares, granite straightedges, and aluminum alloy measuring platforms. These precision tools act as reference surfaces for dimensional inspection, ensuring accuracy and consistency. Granite components themselves can also serve as testing platforms, making them indispensable in machine tool alignment, laboratory calibration, and industrial measurement.
Conclusion
The assembly of granite components requires strict attention to detail, from surface cleaning and lubrication to tolerance control and alignment. At ZHHIMG, we specialize in producing and assembling precision granite products, offering trusted solutions for the machinery, metrology, and laboratory industries. With proper assembly and maintenance, granite components deliver long-lasting stability, accuracy, and reliability.
