Maintaining Zhongrui's shearing machines ensures prolonged lifespan and cutting precision. Daily tasks include cleaning cutting blades and removing metal debris, checking hydraulic oil levels (for hydraulic models), and lubricating moving parts. Weekly maintenance involves inspecting blade alignment with precision gauges (adjusting if deviation exceeds 0.05mm) and testing safety features like emergency stops. Monthly routines require calibrating the backgauge system, checking electrical connections for looseness, and replacing air filters. Hydraulic shears need quarterly oil filtration and annual replacement (every 2,000 hours), while mechanical shears require gearbox oil checks. Annually, schedule professional servicing to inspect the cutting cylinder, replace worn seals, and calibrate the CNC control system. Following Zhongrui's maintenance manual—using genuine spare parts and approved lubricants—prevents blade wear, reduces downtime, and maintains cutting accuracy within ±0.1mm.
