Gantry Surface Grinder: What should be noted when operating a CNC surface grinder?

　　 Gantry surface grinder The key feature of a CNC surface grinder, as explained by the manufacturer’s editor, is that it uses a rotating grinding wheel to machine the workpiece, achieving the specified flatness. Based on the table’s configuration, these grinders can be categorized into rectangular‑frame and annular‑type models. For rectangular‑table surface grinders, the primary parameters are the overall width and length of the worktable; for circular‑table grinders, the main specifications are the diameter of the worktable. Depending on the type of shaft‑like components being processed, they can further be classified into horizontal‑spindle and turntable‑bearing CNC grinders.

　　Gantry Surface Grinder: Precautions for Safe Operation of the Surface Grinder

　　Gantry Surface Grinder: 1. Precise Positioning of the Surface Grinder

　　Outside the working area, 300 CNC surface grinders should be installed. Each leg screw must be tightened securely, and the platform’s levelness in both the front–back and up–down directions should be maintained within 0.04 mm per 100 mm (with stricter tolerances required when installing variable-frequency drives). The cabinet worktop’s level should be checked every three months, and adjustments to its horizontal alignment should be made during operation, with all leg screws tightened as needed.

　　The grinding wheel must be capable of withstanding a rotational speed ratio of 2,000 m/min. The use of damaged grinding wheels is strictly prohibited. Flanges mounted on new grinding wheels must be balanced. Prior to commencing cutting, the grinding wheel must run at high speed for 5 minutes. For CNC grinders with a diameter less than 800 mm, the permissible runout is 0.03 mm; for those greater than 800 mm, it is 0.05 mm.

　　Gantry Surface Grinder: 3. Spindle Bearing of the Surface Grinder

　　Before installing the grinding wheel, ensure that the spindle bearing rotates clockwise. When starting up, first engage the spindle bearing, then proceed with cleaning.

　　A surface grinder uses gear oil with a viscosity of 46#. After three months of use, the gear oil should be replaced; thereafter, change it annually and clean the machine’s oil tank. Check the gear oil level daily, ensuring it remains between the low‑level mark and the mid‑range on the dipstick. Before starting the motor, make sure the main flow‑control lever is fully in the off position. Before operating the hydraulic press, the magnetic oil separator must be activated.

　　Lubricating grease should be rail‑lubricating grease with a viscosity of 32. (We strongly recommend Meiweda No. 2 or No. 1405.) Daily, measure the remaining oil level in the vehicle’s fuel tank to ensure safe operation. Weekly, inspect the guide‑rail oil lines for blockages and check for oil leaks. It is recommended to clean the vehicle’s fuel tank every three months. Add lubricating grease on schedule as specified.

　　Gantry-type surface grinder: 6. Upper and lower assemblies of the surface grinder

　　Do not adjust the up-and-down travel while the operating table is in motion. If the steel cable of the operating table becomes loose, it must be adjusted immediately. (This model is a manual type.)

　　Gantry Surface Grinder: 7. Water Washing and Dust Removal Equipment

　　The dust collector’s filter must be cleaned every two weeks, and the water tank must be flushed with compressed air once a month to maintain the surface grinder.
