Installation andeling is the Foundation (Determines Long-Term Precision)<br>Must use adjustable shock-absorbing feet<br>Four-point or six-point support, three-point positioning with the rest auxiliary; avoid hard contact to generate internal stress and prevent workbench warping and deformation.<br>The floor must be solid and free of settlement<br>Do not place on soft ground or weak floorboards;t foundation subsidence will directly destroy flatness.<br>Allow the machine to settle naturally after installation<br>Let it stand still for 24~48 hours after installation before fine-tunig precision; let stress fully release; do not put into use immediately after installation.<\/p>\n\n\n\n<p>II. Control Environmental Temperature (The Most Critical)<br>Constant temperature environment<br>Ideal tempeature: 20\u2103\u00b12\u2103; avoid large temperature differences between morning and evening, or between winter and summer.<br>Prohibit direct exposure to local heat sources<br>Do not place near windows to be exposedto sunlight, or near welders, ovens, or air conditioner vents; local temperature differences will cause granite to deform slightly.<br>Avoid sudden temperature changes<br>Do not suddenly open rs to let in cold air in winter, or place hot\/cold workpieces directly on the table; both will cause instantaneous precision deviation.<\/p>\n\n\n\n<p>III. Daily Usage Protection<br>Strictly prohibit heavy om impacting or falling<br>Granite is hard but brittle; heavy impacts will produce internal micro-cracks, leading to slow deformation and loss of precision.<br>Prohibit prying, or grinding on the table<br>Do not use it as a fitter&#8217;s bench to knock workpieces, scrape, or use violent clamping; this easily causes chipping and stress ation.<br>Place workpieces gently and use soft protection<br>Place rubber pads or wooden boards under heavy workpieces to avoid hard contact impacting the table surface.<\/p>\n\n\n\n<p>IV. Cleaning and Maintenance Methodsialized dust-free wiping<br>Use anhydrous ethanol, specialized dust-free paper \/ chamois, and wipe in one direction; do not use sandpaper, steel w, or hard-bristled brushes.<br>Keep the table dry and clean<br>Long-term attachment of iron filings, dust, and oil stains will slightly corrode the surface and wear the datum ce.<br>Prohibit strong acids and strong alkalis<br>Do not use disinfectants or strong alkaline cleaners to prevent mineral structure corrosion and surface pitting.<\/p>\n\n\n\n<p>V. Prevent Stress and formation<br>Do not drill holes or cut grooves arbitrarily<br>Random drilling or cutting later will destroy the overall structural stress, causing flatness to quickly become inaccurate.<br>Apply uniform force over te long term<br>Do not press on only one corner of the table for a long time; long-term eccentric loading will produce permanent micro-deformation.<br>Regularly release stress<br>For large grses, perform a re-inspection and re-leveling once a year.<\/p>\n\n\n\n<p>VI. Regular Precision Maintenance<br>Periodic calibration<br>Use levels, optical flats, and right angle gto calibrate flatness and straightness every 3~6 months.<br>Treat minor scratches promptly<br>For minor surface scratches or dents, find a professional manufacturer for local precision grindin and repair; do not grind it yourself.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img alt=\"\" fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"473\" src=\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-1024x473.jpg\" class=\"wp-image-2260\" srcset=\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-1024x473.jpg 1024w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-300x139.jpg 300w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-768x355.jpg 768w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-1536x710.jpg 1536w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-18x8.jpg 18w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908-800x370.jpg 800w, https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/03\/\u5fae\u4fe1\u56fe\u7247_20220725162908.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>How to Maintain High Precision of Granite Precision Workbenches (Practical Comprehensive Methods) I.
