Service and Maintenance job on a Haco Pressmaster 200 Ton 12 foot Press Brake with Iris Lazersafe in Georgia.

Maintaining a Haco Pressmaster 200 Ton 12-foot press brake ensures consistent performance and extends the machine’s lifespan. This service was performed on this equipment in Georgia, focusing on hydraulic oil changes, filter replacements, electronic troubleshooting, bearing upgrades, and precise calibration. Whether you operate this press brake daily or manage maintenance schedules, these insights help keep your machine running smoothly and safely.

Changing Hydraulic Oil and Cleaning Tanks

Hydraulic oil plays a critical role in the press brake’s operation. Using the correct oil type and maintaining clean tanks prevents wear and hydraulic system failures.

• Oil replacement: The service involved changing 60 gallons of AW46 hydraulic oil. This oil type offers excellent viscosity and thermal stability, ideal for heavy-duty press brakes.

• Tank cleaning: Both hydraulic tanks were thoroughly cleaned to remove sludge, contaminants, and old oil residues. Clean tanks reduce the risk of contamination and improve oil circulation.

  
  

Replacing Suction and Pressure Filters

Filters protect the hydraulic system by trapping particles that can damage components.

• Suction filter replacement: The suction filter was replaced to ensure clean oil enters the pump, preventing premature pump wear.

• Pressure filter replacement: The pressure filter was also replaced to maintain clean oil flow to the cylinders and valves.

  
  

Replacing these filters on schedule prevents contamination-related failures and keeps the hydraulic system responsive.

Fixing CAN Communication Alarm Issues

The Haco Pressmaster uses a CAN (Controller Area Network) system for communication between electronic components. Random CAN communication alarms can disrupt operations.

• Alarm diagnosis: The service team identified and addressed the root causes of these alarms, which often stem from wiring issues or faulty electronic boards.

• Electronic Cancon board repair: The Cancon board, responsible for additional axesses, the servo hydraulic pump and hydraulic toolclamping, was fixed on-site, restoring stable communication.

  
  

Addressing Backgauge Locking Alarms

Backgauge locking alarms can halt production and cause frustration.

• Alarm troubleshooting: The service included diagnosing the cause of locking alarms related to the backgauge. Worn bearing cages allowed the bearing balls to get out of position and seize the bearing at times.

• Solutions implemented: Replacement of bearing and repairs were made to eliminate these alarms, ensuring smooth backgauge movement and accurate positioning.

  
  

Proper backgauge function is essential for repeatable bends and correct limb lengths.

Upgrading Bearings with European Sealed SKF Bearings

Bearings support moving parts and hold ballscrews in place with no backlash. Over time, open bearing are prone to dust and dirt entering the raceway and dry bearings corrosion wears them out and require replacement.

• Bearing replacement: All open dry bearings were replaced with new European-made sealed SKF bearings.

• Benefits of SKF bearings: These bearings come pre-lubricated for life and sealed to prevent dirt and moisture ingress, reducing maintenance needs.

  
  

Upgrading to sealed bearings enhances machine durability and reduces the frequency of bearing-related breakdowns.

Geometric Alignment and Calibration

Precision is key in press brake operation. Geometric alignment and calibration ensure the machine bends accurately.

• X and R axis alignment: The X (horizontal) and R (backgauge) axes were geometrically aligned along with the fingers.

• Recalibration: Both axes were recalibrated to factory specifications.

• Tool and adapter height checks: All tool heights and adapter heights were measured and calibrated, along with the Y1 and Y2 axis calibration. Making sure the Lazersafe Iris operates flawlessly

  
  

These adjustments guarantee that bends meet exact specifications, reducing scrap and rework.

Backing Up the Control System

Backing up the control system safeguards machine settings and programs.

• Control backup: A full backup of the control system was performed to protect against data loss.

• Importance: This backup allows quick restoration in case of control failure or accidental data deletion.

  
  

Maintaining updated backups minimizes downtime and preserves production data integrity.
