Precision granite components serve as the core precision benchmarks for semiconductor equipment, precision testing instruments and laser processing devices. Though featuring high stability, ultra-low deformation and excellent vibration resistance, granite is a brittle natural stone. Improper storage, cleaning, operation and environmental changes will cause gradual precision loss, affecting equipment accuracy and service life. Standard daily maintenance is essential to maintain long-term nano-scale precision and stable operation.
1. Standard Storage Management
Store granite components in a constant-temperature, dry, dust-free and non-corrosive indoor environment, avoiding places with drastic temperature changes such as vents and heat dissipation outlets. Use uniform multi-point flexible supports instead of single-point support, tilting or stacking. Never place heavy or sharp objects on the surface to prevent scratches, chipping and deformation. For drilled and grooved custom components, seal holes and grooves to avoid dust and moisture accumulation.
2. Scientific Cleaning Methods
Keep the granite surface clean to guarantee benchmark accuracy. Wipe fine dust gently with professional dust-free microfiber cloths. For slight oil stains, use neutral stone cleaning agents and dry immediately. Do not use hard brushes, abrasive tools, strong acid, alkali or volatile solvents, which will damage the polished precision surface. Avoid direct water flushing to prevent internal moisture and residual scale.
3. Standard Operating Specifications
Avoid violent operation, heavy impact and falling metal workpieces during equipment debugging and processing. Strictly follow the rated load capacity to prevent precision drift caused by long-term overload. Regularly check embedded parts, positioning holes and sealing grooves for looseness and offset. Never conduct high-temperature operations such as welding and cutting on granite surfaces to avoid irreversible thermal deformation.
4. Strict Environmental Control
Maintain a constant temperature and humidity in the working environment to reduce thermal expansion and contraction deformation. Keep the workplace dry, clean and free of corrosive gas and heavy dust. Isolate external vibration and equipment resonance to stabilize the working environment, which is critical for sustaining long-term ultra-precision performance. 
5. Regular Calibration and Inspection
Even without visible damage, granite components will produce tiny precision errors after long-term operation. Regularly calibrate flatness, straightness, levelness, hole and groove accuracy. Do not polish or modify components privately. ZHHIMG provides professional precision re-inspection, calibration and after-sales maintenance services to eliminate hidden precision risks.
6. Core Maintenance Taboos
Six key taboos must be observed: drastic temperature fluctuation, heavy impact and stacking, corrosive cleaning agents, high-temperature baking, overload operation, long-term damp and dusty storage. Standard daily maintenance can maximize granite stability, extend service life and ensure consistent precision of high-end precision equipment.
