Daily Maintenance & Care Points for Hydraulic Presses

Maintenance for four-column and single-arm hydraulic presses focuses on three core areas: hydraulics, electrical systems and machine frames. Daily: Clear waste from worktables, inspect tubing for leakage, run machine idle for 3 minutes to warm up. Weekly: Lubricate slide guide rails, fasten worktable bolts. Monthly: Clean oil tank filters, verify pressure gauge accuracy. Quarterly: Replace hydraulic oil, inspect sealing components for aging. Annually: Test frame weld seams, calibrate slide parallelism, replace aged cables. Insufficient maintenance causes insufficient pressure, slide jamming and oil seal leakage, shortening cylinder service life. All machines are equipped with photoelectric safety protection devices – inspect their responsiveness daily to avoid stamping injuries. The manufacturer sends engineers for regular pressure parameter calibration.
