About Lathe Maintenance

1. Precautions when clamping and correcting workpieces
Before clamping the workpiece, the sand and other impurities in the workpiece must be removed to prevent the impurities from being embedded in the sliding surface of the slide plate, aggravating the wear of the guide rail or "biting" the guide rail.
When clamping and correcting some workpieces with large size, complex shape and small clamping area, a wooden bed cover should be placed on the lathe bed under the workpiece in advance, and the workpiece should be supported by a pressure plate or a movable ejector to prevent it from falling and damaging the lathe. If the position of the workpiece is found to be incorrect or skewed, do not knock it hard to avoid affecting the accuracy of the lathe spindle. The clamp, pressure plate or ejector must be slightly loosened before making step-by-step corrections.
2. Placement of tools and turning tools
Do not place tools and turning tools on the bed to avoid damaging the guide rails. If you need to place them, cover the bed with a bed cover first, and place the tools and turning tools on the bed cover.
(1) When sanding a workpiece, cover the bed surface under the workpiece with a bed cover or paper; after sanding, wipe the bed surface carefully.
(2) When turning a cast iron workpiece, install a rail cover on the choke plate and wipe off the lubricating oil on the bed surface where chips can splash.
(3) When not in use, the lathe must be cleaned and maintained to prevent chips, sand or impurities from entering the sliding surface of the lathe guide rails, "biting" the guide rails or increasing their wear.
(4) Before using the cooling lubricant, the garbage in the lathe guide rails and the cooling lubricant tray must be removed; after use, the cooling lubricant on the guide rails must be wiped dry and the machine lubricant must be added.
