A press brake machine is one of the most vital assets in any fabrication workshop. It bends, shapes, and forms sheet metal with precision — but to ensure consistent results and long-term performance, regular maintenance is essential.

Whether you use an NC press brake, CNC press brake machine, or hydraulic press brake machine, proper care helps avoid downtime, extends component life, and maintains bending accuracy.

In this guide, experts at Rajesh CNC, India’s leading CNC press brake manufacturer, share proven maintenance tips for press brake machines that guarantee reliability, precision, and durability.

Why Press Brake Maintenance Matters

A neglected hydraulic press brake machine loses alignment, accuracy, and power over time. Minor issues such as oil contamination or loose components can escalate into major breakdowns if not addressed.

Proper maintenance ensures:

  • Consistent bending accuracy
  • Reduced repair and downtime costs
  • Extended lifespan of hydraulics and tooling
  • Higher productivity and safety

By following a routine press brake machine maintenance checklist, you can significantly improve efficiency and reduce production loss.

Daily Maintenance Checklist

Daily care keeps your CNC press brake machine running smoothly and prevents minor issues from escalating.

1. Clean Machine Surfaces

Remove dust, metal shavings, and oil residue after every shift. Clean the bed and ram using lint-free cloths.
Dirt buildup affects hydraulic seals and can scratch critical parts.

2. Check Oil Levels

Ensure the hydraulic tank is filled to the recommended level. Use manufacturer-approved oil for your hydraulic press brake machine.
Low oil can cause inconsistent pressure and cylinder damage.

3. Inspect Foot Pedal & Emergency Stop

Ensure that all operator safety switches function properly. Faulty safety devices can lead to serious accidents.

4. Verify Back Gauge Movement

Run a quick test to check the back gauge alignment. Misalignment can cause uneven bends in sheet metal fabrication.

5. Power Down Properly

Always switch off the main power and release hydraulic pressure before closing for the day to prevent system strain.

Weekly Maintenance Checklist

1. Lubricate Moving Parts

Use grease or oil on guide rails, pivot points, and ram slides. Proper lubrication prevents friction and reduces wear on your CNC press brake machine.

2. Inspect Blade Alignment

Check blade clearance for accuracy. A small gap difference can cause bending errors and reduce blade life.

3. Examine Hydraulic Hoses

Look for oil leaks, cracks, or loosened fittings in the hydraulic circuit. This is crucial for maintaining stable operation in hydraulic press brake machines.

4. Clean Electrical Panels

Dust in control cabinets can lead to overheating or short circuits. Clean gently using compressed air.

5. Check Tool Clamping System

Inspect punch and die clamping mechanisms. Misalignment leads to poor bending quality and tool wear.

Monthly Maintenance Checklist

1. Replace Hydraulic Oil Filters

Contaminated oil is the #1 enemy of hydraulic press brake systems. Replace filters monthly or as per your manufacturer’s recommendations.

2. Inspect Servo Motors & Encoders

Ensure servo drives on the CNC press brake machine operate smoothly without noise or vibration. Calibrate axes if needed.

3. Verify Pressure Gauges

Monitor hydraulic pressure and ensure it matches your rated tonnage (e.g., 100T, 160T, 250T). Incorrect pressure affects bending quality.

4. Check Bolts & Fasteners

Tighten all frame bolts and moving components. Heavy usage can loosen parts, especially in multi-shift operations.

5. Test Machine Accuracy

Perform trial bends to confirm repeatability and tolerance within ±0.05 mm — the standard for Rajesh CNC press brake machines.

Yearly Preventive Maintenance Tips

Annual maintenance helps you spot hidden issues and prepare your machine for heavy industrial workloads.

1. Replace Hydraulic Oil

Drain and refill the tank with fresh, high-quality hydraulic fluid every 12 months.
Always use oil recommended by your CNC press brake manufacturer India to prevent contamination.

2. Inspect Cylinders & Seals

Check hydraulic cylinders for leakage and wear. Replace seals to prevent pressure loss in hydraulic press brake machines.

3. Recalibrate CNC Controller

If your machine uses Delem, Estun, or Siemens control systems, recalibration ensures bending precision.
Rajesh CNC service engineers offer professional CNC press brake maintenance support for controller and axis alignment.

4. Evaluate Electrical Components

Replace worn-out relays, switches, and wiring to avoid unexpected breakdowns.

5. Conduct a Full Service Audit

Schedule a professional inspection with your CNC press brake supplier to assess wear patterns, safety features, and calibration.

Common Press Brake Maintenance Mistakes

Even experienced operators make small errors that shorten the lifespan of their CNC press brake machines.
Avoid these common mistakes:

  1. Ignoring hydraulic oil contamination
  2. Using incorrect lubricants
  3. Overlooking blade clearance adjustments
  4. Neglecting to tighten fasteners regularly
  5. Operating without periodic calibration

Following these maintenance guidelines ensures that your CNC press brake machine manufacturer from India investment continues to perform flawlessly for years.
