CNC gantry milling machine It is a common type of machine tool that can use multiple milling cutters to machine surfaces simultaneously, offering high machining accuracy and productivity. It is well suited for machining flat and inclined surfaces on large workpieces in batch and mass production. To ensure the efficiency of CNC gantry milling machines, users must perform regular maintenance and servicing, which helps extend the machine’s service life. Below, a manufacturer of CNC gantry milling machines shares some key maintenance and upkeep practices.

　　Maintenance procedures for CNC gantry milling machines:

　　1. Cleaning: Disassemble and clean the oil‑felt pads on all components of the CNC gantry milling machine; wipe all sliding surfaces and guideways; clean the worktable, as well as the cross‑feed and vertical lead screws; and wipe the tool‑feed drive mechanism and the tool holder.

　　2. Lubrication: CNC gantry milling machine Clean and ensure all oil holes are unobstructed, then lubricate them. Apply lubricant to all guide rails, sliding surfaces, and lead screws, and periodically inspect the transmission mechanism’s oil tank—checking the oil level and topping up the oil to the specified mark.

　　3. Tightening: Inspect and tighten the clamping plates and shim screws, and also check and tighten the slide block mounting screws, the feed drive mechanism, the handwheel, the table support screws, the ram‑top screws, and periodically inspect and tighten any other loose fasteners.

　　4. Adjustment: Inspect and adjust the lathe’s belt, clamping plates, and shims to ensure proper tension; also inspect and adjust the slide block and lead screw to ensure smooth operation.

　　5. Corrosion protection for CNC gantry milling machines: Remove rust from all components, protect painted surfaces, and avoid impacts. When the machine is out of service or in standby, apply anti-corrosion oil to the guideways, sliding leadscrews, handwheels, and other exposed parts that are prone to rust.

　　In addition, users should also take note when operating a CNC gantry milling machine:

　　1. CNC gantry milling machine When loading or unloading workpieces, the cutting tool must be retracted. During machining, the head and hands must not be brought close to the milling surface. When setting up the tool on a gantry milling machine, feed must be slow or performed manually; rapid feed is prohibited. While feeding the cutter, stopping is not permitted.

　　2. When rapidly retracting or advancing the tool, ensure that the handle of the Xuzheng milling machine does not strike anyone. Do not feed the tool in too quickly, and never change speeds suddenly. The limit stops on the Xuzheng milling machine must be properly adjusted.

　　3. Before and after machining workpieces, adjusting cutting tools, or tightening the gearbox, the machine tool must be stopped. When removing or installing end mills, place a wooden board on the worktable; when loosening the milling cutter’s clamping nut, do not apply excessive force.

　　4. In general, a single chuck on a CNC gantry milling machine can hold only one workpiece. If a chuck clamps more than one workpiece—even if securely fastened—the significant forces generated during rough cutting can cause the workpieces to slip relative to each other, potentially resulting in the workpieces flying out, tool breakage, and injuries.

　　That concludes the maintenance procedures for CNC gantry milling machines. For more information on CNC gantry milling machines, please contact Nantong Yongchang CNC Machinery Technology Co., Ltd. by phone.
