Preventive maintenance is essential for maximizing press brake machine service life and maintaining consistent bending accuracy across production runs. Daily maintenance procedures include checking hydraulic oil levels in the power unit for hydraulic models, verifying that the pump operates without unusual noise or vibration, inspecting all hoses and fittings for leaks, and ensuring the pressure relief valve functions correctly. For electric servo press brakes, daily maintenance focuses on visual inspection of machine condition, checking for unusual sounds from servo motors or ball screws, and verifying that all safety systems including light curtains and emergency stops are operational. The lubrication system requires daily verification that oil or grease reaches all moving joints, bearings, and pivot points, with manufacturer-recommended lubricants applied to slide ways, ram guides, and ball screws. Weekly inspections should focus on tooling condition, checking punches for wear or chipping, dies for cracking, and verifying that quick-clamp systems are secure. Backgauge calibration should be verified weekly, checking that positioning accuracy remains within specification and that all axes move smoothly without binding or excessive backlash. Monthly maintenance involves cleaning the hydraulic system breather cap, inspecting all electrical connections for tightness, checking the condition of safety guards and interlocks, and verifying that all fasteners remain torqued to specification. For machines with hydraulic crowning systems, the crowning cylinders and hydraulic lines should be inspected for leaks or irregular operation. Every 500 operating hours, hydraulic fluid samples should be analyzed for contamination, with fluid replacement recommended when oxidation or particulate levels exceed manufacturer specifications. The cooling system, which removes waste heat from the hydraulic system or servo drives, requires inspection of coolant levels and quality. Every 1,000 operating hours, inspect cylinder seals for leakage, verify backgauge ball screw lubrication, and check linear guide rail condition. For electric servo press brakes, inspect servo motor bearings and ball screw preload. Following these maintenance protocols reduces unplanned downtime significantly and extends equipment service life by 10 to 15 years compared to neglected machines. Our press brake machines come with a 2-year limited machine warranty.
