Dusting: Use a lint-free cloth dry air gun to blow away metal chips and dust from the workbench surface. Debris stuck in the guide rails will scratch the granite reference surface.
Cleaning: Wipe the surface with a small amount of neutral anhydrous alcohol. Diesel, engine oil, strong acids, strong bases, and banana water are strictly prohibited. Oil stains penetrating the micropores of the stone will permanently turn black and cannot be polished away.
Leveling Check: Observe the equipment’s bubble level. For shifts with high workshop vibration, adjust the leveling feet once in the morning and once in the evening.
Protection: Handle workpiece edges and fixtures gently. Direct impact from hard steel parts will cause dents and destroy the planar reference.<\/li>\n\n\n\n
Wipe the surface with a specialized granite cleaning paste to remove light oil stains and fingerprints;
Clean dust accumulation at the bottom of the base and on the leveling feet to prevent debris under the feet from causing the base to tilt;
Check T-slot threaded holes for iron chip blockage, and apply a small amount of anti-rust grease to the threads after cleaning.<\/li>\n\n\n\n
Leveling Re-measurement: Use a precision level to re-measure the planar level of the base. If the deviation exceeds 0.02mm\/m, adjust the leveling feet promptly;
Seepage Prevention Maintenance (Critical): For precision Grade 00 bases, a thin layer of specialized granite protective sealant can be applied to seal the micropores of the stone, preventing oil penetration and moisture;
Check for impact damage on the base edges and corners. Record the positions of small dents to avoid errors when workpieces fit during high-precision measurement.<\/li>\n\n\n\n
Accuracy Re-inspection: Send to the metrology room to test flatness and straightness. If large-area scratches or dents appear, return to the factory for grinding and re-polishing the reference surface;
Completely disassemble and clean the leveling feet, and replace aged shock-absorbing rubber pads;
For bases in humid workshops, implement moisture isolation at the bottom by adding moisture-proof pads to prevent the stone from expanding and deforming due to long-term moisture.
III. Strictly Prohibited Operations (Irreversible Damage to Granite Base)
Prohibit direct grinding, cutting, or hammering of workpieces on the surface, which easily causes point-like dents;
Prohibit long-term soaking of the surface in strong acids, strong bases, or cutting fluids;
Prohibit long-term heavy pressure on one side by heavy workpieces; long-term uneven stress will slowly cause deformation;
Prohibit placing high-temperature workpieces directly on the surface (soldering irons, hot-pressed parts). Local high temperatures will generate thermal stress, causing permanent deformation;
Prohibit using steel wool or sandpaper to directly grind the workbench surface, as it will destroy the polished mirror reference;
Prohibit forklifts or heavy objects from colliding with the sides of the base.
IV. Common Faults and Repair Solutions
Surface Oil Seepage and Blackening
Mild: Repeatedly wipe with specialized degreasing paste; Severe: If severe oil seepage cannot be removed, the base must be returned to the factory for re-grinding a layer.
Small Surface Scratches
Shallow scratches: Manually polish locally with polishing paste; Deep scratches and dents: The entire machine must be disassembled and repaired on a precision grinder at the factory.

Base Dampness and Whitening (Common in humid southern workshops)
Wipe dry and dry with heat, evenly apply stone sealant, and add a moisture-proof isolation pad at the bottom.<\/li>\n<\/ol>\n\n\n\n

Lay a thin silicone protective mat in the inspection area to provide cushioning and prevent impact when placing hard and workpieces;
Avoid direct sunlight on the base in the workshop as much as possible, as local temperature differences will increase measurement errors;
Cover the tabletop with a dustproof waterproof cover when the machine is shut down for a long period of time;
For new bases, re-check the level once a week for the first 3 months, and to once a month after it stabilizes.<\/p>\n\n\n\n![\"\"](\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/06\/20260617-103227.png\")
