Proper maintenance is crucial for ensuring optimal performance and longevity of a sheet metal press brake. Here are some key steps: Visual Inspection: Conduct a thorough visual inspection of all areas to identify any potential issues or signs of wear. Hydraulic System Check: Examine the hydraulic circuit, including the oil level, temperature, cleanliness, and viscosity. Mechanical System Check: Inspect mechanical components for any loose bolts, worn bearings, bushings, pins, keyways, gears, splines, shafts, couplings, belts, pulleys, chains, or sprockets. Electrical System Check: Check the electrical system for loose connections, damaged wires or cables, switches, relays, fuses, circuit breakers, transformers, or contactors. Tooling Check: Examine the punch and die tools for signs of wear or damage, and replace them if necessary.
