CNC vertical lathes are high-precision heavy industrial equipment with high purchase costs. Their lifespan and the duration of their machining accuracy depend entirely on the quality of daily maintenance. Many machining plants focus only on production schedules, neglecting basic maintenance, often resulting in decreased accuracy, frequent malfunctions, and frequent downtime for repairs after only two or three years of use.
Proper maintenance can be divided into three parts: daily inspection, weekly maintenance, and monthly overhaul.
Before starting the machine each day, check the lubricating oil level, hydraulic system pressure, and cooling system circulation. Ensure that the guide rails and worktable are free of metal shavings and debris to prevent scratches on precision working surfaces.
After finishing work each day, promptly clean away machining shavings, wipe the worktable and guide rail surfaces, and ensure proper dust protection for the equipment.
Weekly, a comprehensive inspection of the transmission structure, lead screw, and guide rail lubrication status is required. Check the electrical wiring and control panel buttons for proper functioning, and check for leaks in the hydraulic lines.
Monthly in-depth maintenance includes calibrating the worktable’s machining accuracy, checking the spindle’s operating status, verifying the turret’s positioning accuracy, tightening all machine body fixing screws, and proactively identifying and replacing aging parts.
Furthermore, the equipment must not be operated continuously under excessive load for extended periods. Processing should be performed according to the equipment’s rated load capacity. For equipment that is not in use for extended periods, it should be periodically powered on and run idle to prevent internal parts from becoming damp and rusting.
A comprehensive maintenance system can reduce downtime due to sudden malfunctions and preserve the equipment’s original machining accuracy for a longer period.
