Maintaining a CNC press brake is critical to ensuring long-term precision, minimizing downtime, and extending the machine’s lifespan—typically 15+ years with proper care. At RAYMAX, we provide clear maintenance guidelines tailored to our machines, leveraging our 22 years of manufacturing expertise and feedback from 4000+ global clients across automotive, aviation, and shipbuilding industries. Daily Maintenance Tasks form the foundation of upkeep. Start by inspecting the hydraulic system: check the oil level (ensuring it stays between the “min” and “max” marks on the tank) and look for leaks in hoses or fittings—even small leaks can reduce pressure, leading to inaccurate bending (e.g., a 0.5-degree deviation in automotive chassis parts). Clean the hydraulic oil filter monthly to prevent debris from damaging the system; our machines have easily accessible filters to simplify this task. Next, inspect the tooling (punch and die) for wear, cracks, or metal chips—worn tooling can produce burrs on stainless steel petrochemical components or uneven bends in railway track supports. Wipe down the tooling with a clean cloth and apply a light layer of anti-rust oil if the machine will be idle for more than a week. Weekly Maintenance focuses on moving parts. Lubricate the back gauge rails, ram guides, and tooling clamps using the recommended oil (specified in our machine manual)—this reduces friction and prevents premature wear. For example, a railway client’s 2000kN CNC press brake maintained consistent ±0.08mm accuracy for 5 years by following this lubrication schedule. Also, test the safety features weekly: press emergency stop buttons to ensure immediate shutdown, and verify that light curtains stop the machine when an object enters the bending area—critical for compliance with CE and ISO 9001 safety standards. Monthly and Annual Tasks address long-term performance. Monthly, calibrate the CNC system using a coordinate measuring machine to confirm bending accuracy—this is especially important for aviation clients producing aluminum alloy wing components with ±0.08mm tolerances. Annually, replace the hydraulic oil (using the grade recommended by RAYMAX) and inspect the hydraulic cylinders for signs of wear, such as scratches or leaks. Our technical team can also perform an annual comprehensive inspection, checking electrical connections, CNC software updates, and structural integrity (e.g., frame deformation for heavy-duty models). Leverage the predictive maintenance feature of our advanced CNC press brakes. The system monitors usage data (e.g., number of bends, hydraulic pressure) and sends alerts for upcoming service—such as “replace tooling after 50,000 bends” or “check hydraulic seals after 1000 hours of operation.” A power plant client used this feature to replace a worn hydraulic seal 2 weeks before failure, avoiding unplanned downtime that would have delayed boiler support production. Finally, train operators on basic maintenance. Our on-site and online training programs teach operators to identify early signs of issues (e.g., unusual noise from the hydraulic system, uneven bending) and perform simple tasks like cleaning tooling or checking oil levels. By following these steps, you can ensure your RAYMAX CNC press brake maintains peak performance, delivers consistent quality, and supports your production goals across industries.
