Press Brake Repair & CNC Press Brake Service
We provide on-site press brake repair, troubleshooting, and CNC press brake service for metal fabrication shops across the U.S.
Our technicians help diagnose hydraulic issues, CNC control errors, backgauge problems, Y1/Y2 axis faults, servo drive alarms, electrical issues, pressure loss, oil leaks, and inconsistent bending accuracy.
Send us your machine model, error code, photos, video, and ZIP code — we’ll help identify the next step and prepare for service.

Press Brake Problems We Repair
We service hydraulic press brakes, CNC press brakes, mechanical press brakes, and industrial bending machines used in sheet metal fabrication, structural metal work, HVAC, enclosures, cabinets, signage, and production manufacturing.
Common service calls include machines that will not start, lose hydraulic pressure, bend inconsistently, show CNC control errors, fail to position the backgauge, or stop during the bending cycle.
Common Press Brake Symptoms
| Problem | Possible Cause |
|---|---|
| Press brake will not start | Power issue, emergency stop circuit, safety relay, PLC, contactor, CNC control fault |
| CNC control shows an error code | Control parameters, drive fault, encoder issue, sensor failure, safety circuit problem |
| Machine does not hold bend angle | Tooling wear, crowning issue, Y1/Y2 synchronization, hydraulic pressure, CNC setup |
| Backgauge will not move or position correctly | Servo motor, drive, encoder, ball screw, linear guide, limit switch, control parameter |
| Hydraulic pressure drops | Pump, valves, seals, cylinders, filters, hydraulic oil, internal leakage |
| Oil leak | Hydraulic hose, fitting, cylinder seal, manifold, valve block |
| Uneven bend from left to right | Y1/Y2 axis issue, linear scale, proportional valve, ram alignment, tooling setup |
| Hydraulic oil overheats | Clogged filters, pump wear, cooling issue, incorrect oil, overworked hydraulic system |
What We Service
- Hydraulic pumps, valves, cylinders, hoses, filters, and manifolds
- CNC controls, PLCs, operator panels, and machine parameters
- Servo drives, motors, encoders, linear scales, and position sensors
- Y1/Y2 ram axes, X/R/Z backgauge axes, and synchronization systems
- Backgauge assemblies, ball screws, linear rails, fingers, and stops
- Crowning systems and bend angle accuracy
- Electrical cabinets, relays, contactors, power supplies, and safety circuits
- Foot pedals, light curtains, laser safety systems, and emergency stop circuits
- Tooling clamps, punches, dies, and mechanical alignment
CNC Controls and Press Brake Brands
We help troubleshoot press brakes equipped with common CNC control systems, including Delem, Cybelec, ESA, Estun, and other industrial controllers.
We also work with many press brake brands used in U.S. fabrication shops, including Amada, Trumpf, Durma, Baykal, Ermaksan, Accurl, Yawei, LVD, Bystronic, SafanDarley, HACO, Prima Power, Cincinnati, Pacific, Wysong, Chicago, Betenbender, Baileigh, HARSLE, KRRASS, ADH, and others.
If your machine brand is not listed, send a photo of the nameplate, CNC control, and error screen. We’ll check the service path before scheduling the repair.
How Our Press Brake Repair Process Works
- Send machine details. Send the brand, model, serial number if available, ZIP code, photos, error code, and a short video of the problem.
- Initial troubleshooting. We review the symptoms and identify whether the issue appears hydraulic, electrical, mechanical, CNC/control-related, or safety-related.
- Service planning. If on-site service is needed, we help prepare the technician with the likely tools, parts, control information, and troubleshooting path.
- On-site diagnosis. The technician checks hydraulic pressure, CNC alarms, servo drives, sensors, backgauge movement, Y1/Y2 synchronization, safety circuits, and bend accuracy.
- Repair and testing. After repair, the machine is tested for basic operation, positioning, repeatability, safety function, and bending accuracy.
What to Send Before Service
- Machine brand and model
- Serial number or nameplate photo
- CNC control brand and model
- Photo of the error code or alarm screen
- Short video of the machine fault
- Description of what happened before the issue started
- Your ZIP code
- Whether the machine is down or still running
- Any recent repairs, crashes, power issues, or parameter changes
Send photos and the error code — we’ll help identify the likely repair path.
Press Brake Repair FAQ
How much does press brake repair cost?
The cost depends on the machine model, type of failure, travel requirements, parts availability, and whether the issue is hydraulic, electrical, mechanical, CNC-related, or safety-related. Send the machine model, error code, photos, video, and ZIP code for a preliminary service path.
Do you offer on-site press brake repair?
Yes. Many press brake issues require on-site troubleshooting because hydraulic pressure, ram movement, backgauge positioning, Y1/Y2 synchronization, safety circuits, and bend accuracy must be checked directly on the machine.
Can you troubleshoot a CNC press brake remotely?
Some issues can be reviewed remotely using photos, videos, alarm codes, control screenshots, and machine details. However, hydraulic, electrical, servo, safety, and accuracy issues often require on-site diagnosis.
Why is my press brake bending different angles across the part?
Common causes include worn tooling, incorrect crowning, Y1/Y2 synchronization problems, hydraulic imbalance, linear scale issues, ram alignment, incorrect material setup, or CNC parameter issues.
What should I do if my press brake shows a CNC alarm?
Take a photo of the alarm screen, write down the control model, avoid changing parameters without diagnosis, and send the information for troubleshooting. The alarm may be related to a drive, encoder, sensor, safety circuit, PLC, or control parameter.
What press brake brands do you service?
We help troubleshoot many brands used in U.S. metal fabrication shops, including Amada, Trumpf, Durma, Baykal, Ermaksan, Accurl, Yawei, LVD, Bystronic, Cincinnati, Pacific, Wysong, Chicago, Betenbender, and others. Service availability depends on the model, issue, location, and parts access.
