The maintenance of woodworking machinery can be divided into three types: minor repairs, medium repairs and major repairs.
(1) Minor repair content.
1) Partial disassembly of severely worn and damaged parts
2) Clean the disassembled parts for repair or replacement
3) Check the spindle, cutter shaft and saw shaft, and repair if necessary.
4) Dressing or replacement of wearing parts such as bearings, guides and other friction surfaces
5) Dressing of working surfaces such as work table, tool rest, guide ruler, etc.
6) Inspection and adjustment of operating mechanisms, electrical interlocks, switches, and positioners.
7) The inspection of the matching accuracy of the transmission parts, the adjustment of the spring tension and the adjustment of the balance of the cutter head and the movement of the worktable.
8) Adjustment, repair and replacement of oil for hydraulic systems and lubricating devices.
9) Inspection and adjustment of protective devices and dust collectors.
10) No-load test run of the machine tool, check noise and temperature rise, work accuracy check
·(2) Contents of middle school

2) Replace wearing parts, repair spindle, cutter shaft and saw shaft
3) Repair workbench, guides and friction surfaces
4) Repair hydraulic and lubricating equipment, replace oil
5) Replace the transmission parts and assemble the machine tool.
6) Repair guards.
7) According to the technical requirements of the equipment, check the accuracy and smoothness of the machine tools and products
8) Check noise and temperature rise during no-load operation.
9) Spray paint on the outer surface of the machine tool.
10) Restoration of marks, reticle, scale and other marks
(3) Overhaul content.
