Five Key Routine Maintenance Points for CNC Shearing Machines
Standardized maintenance is essential to sustain long-term precision of CNC shearing machines.
- Pre-shift daily inspection: Match blade clearance to sheet thickness, clean metal debris from the table, test idle backgauge movement.
- Weekly maintenance: Clean linear guide rail dust covers, apply lubricating grease, fasten backgauge lead screw bolts.
- Monthly maintenance: Blow dust off electrical control cabinets, inspect wiring for aging or damage.
- Semi-annual maintenance: Replace hydraulic oil, clean tank filter screens, check blade wear and grind blades if burrs exceed standards.
- Annual maintenance: Retighten all machine bolts, calibrate backgauge positioning accuracy, replace backup batteries for the CNC system. Neglecting maintenance leads to dimensional deviations, blade chipping and hydraulic leakage, shortening equipment service life by 30%. The manufacturer provides a complete maintenance manual, with after-sales engineers conducting regular on-site inspection and guidance.
