Granite mechanical components are known for their superior accuracy and stability, making them ideal for high-precision applications in machining and testing environments. Their exceptional qualities ensure consistent precision over time, making them crucial for ensuring the accuracy and quality of both processing and inspection tasks.
Key Uses and Functions:
Cleaning and Preparation of Parts
Before assembly, it is essential to clean parts thoroughly to remove any residual casting sand, rust, or chips. This is particularly important for critical components such as gantry machines or internal cavities, which should be coated with anti-rust paint. For cleaning, use diesel, kerosene, or gasoline as a solvent, followed by drying with compressed air.
Lubrication of Mating Surfaces
Before assembling mating surfaces or parts, always apply lubrication to prevent wear and ensure smooth operation. This is especially important for components like bearings in the spindle box and lead screw nuts in lifting mechanisms.
Accuracy of Fitting Dimensions
When assembling, it is essential to check the accuracy of fitting dimensions. This includes verifying the fit between the spindle neck and bearing, the bearing housing and the spindle box, and the center distance between these components. It is recommended to recheck or sample inspect these dimensions to ensure proper alignment.
Gear Assembly
During gear assembly, ensure that the axles of the gears are aligned within the same plane and are parallel to each other. Maintain proper meshing clearance, and ensure that the axial misalignment is ≤2mm.
Inspection of Connecting Surfaces
Check the joining surfaces of connected parts for smoothness and flatness. If any deformation is detected, rework the surfaces to remove burrs, ensuring that the mating surfaces are clean, flat, and aligned.
Sealing Components
Ensure that sealing components are pressed parallel into their grooves without distortion or damage to the sealing surface. Proper installation of seals is critical to preventing leaks and ensuring long-lasting performance.
Pulley Assembly
When assembling pulleys, ensure that the axes of the pulleys are aligned and parallel. Any significant offset will cause uneven tension, which may lead to slippage or accelerated wear. Additionally, ensure that the triangular belts are of uniform length to prevent vibrations during operation.
Bearing Installation
Before installing bearings, thoroughly clean them to remove any anti-rust coating. During installation, check the bearing tracks for corrosion and ensure the bearing rotates smoothly. Lubricate the bearing surfaces before installation, and if any significant pressure difference is noticed, stop and check. When installing, ensure the unmarked side faces inward, and use appropriate force to evenly install the bearing without causing damage to the rolling tracks.
Threaded Connections
To prevent loosening, threaded connections should include anti-loosening devices such as double nuts, spring washers, split pins, or lock washers, depending on the design requirements. Use a symmetrical tightening sequence when securing bolts, particularly for components with multiple bolts. For threaded connections, ensure the threads protrude from the nut to provide secure fastening.
Conclusion
Granite non-standard mechanical components offer unmatched precision and stability, ensuring high-quality performance in a variety of mechanical applications. By following the proper cleaning, lubrication, and assembly procedures outlined above, you can maximize the functionality and longevity of these components.
