UmproTech / CNC Press Brake Service
CNC press brake repair.
Control, drive and axis faults.
A controller alarm, lost reference or backgauge fault can interrupt the whole job. Send the exact alarm, machine identity and controller model so the service team can review the right starting point.

Choose what you are seeing
Start the request with the reported problem.
Select a symptom to carry it into the service form. Add the machine identity, fault details and your service ZIP.
Servo or Y1/Y2 axis fault
Record the exact displayed code and the affected axis if shown. Explain whether it appears at startup, reference or during the job.
Request an axis-fault reviewBackgauge loses position
Describe the position or reference issue and the axis involved. Include the machine and control model and any existing fault evidence.
Request backgauge serviceFault after a change or restart
Describe what changed before the fault began: a restart, service visit, component replacement or parameter change. Include existing records.
Request a startup-fault reviewPrepare the service information
Send the exact alarm and the full machine identity.
Machine and controller
Machine brand, model, serial number and full controller model. Include existing nameplate and controller photos.
Fault evidence
Exact alarm text or code, named axis and an existing screen photo or video if available.
Fault history
When it first appeared, the cycle stage, whether it repeats and any preceding changes.
Service context
Your ZIP, best contact and whether production has stopped or the fault is intermittent.
The email link opens your email app with a checklist. Attach your existing files before sending.
Machine-specific scope
Review the control and machine as one system.
The exact machine, control version and available documentation define the service path. The review can cover the relevant control, motion and interface components.
CNC and operator interface
Controller identification, displayed alarms, operator-panel concerns and available configuration records.
Motion and position feedback
The reported drive, motor, encoder, scale, backgauge or axis concern, as applicable to the machine.
Machine integration
Relevant PLC, communication, input/output and machine-interface information available for the case.
Controller & backgauge modernization
Review repair and retrofit against the work you need.
If the existing control or positioning system is limiting the machine, describe the required parts, axes and operating needs. The retrofit review connects those requirements to the current machine architecture.
Request a retrofit reviewWhat happens next
Move toward a defined service scope.
- Review the evidence. Identify the machine, reported issue and information still needed.
- Choose the next evaluation. Review whether remote evidence, part identification or a site evaluation fits the case.
- Confirm the proposed work. Agree on the scope, cost and any visit arrangements before scheduling.
UmproTech reviews U.S. service requests by machine and ZIP. On-site work depends on the case and confirmed availability.
Before you request service
Questions about this repair path.
Can you diagnose my machine from the alarm number?
The exact alarm is useful alongside the full controller model, machine identity and the circumstances in which it appears. Codes and service paths depend on the installed system. Send the screen and machine details for review.
Can you review Delem, Cybelec, ESA or Estun controls?
Send the full model and controller photo, together with the press brake identity. Service feasibility, documentation and component access are reviewed for the specific installed system before compatibility or work scope is confirmed.
Can an older controller be replaced?
A retrofit is evaluated against the existing machine mechanics, hydraulics, feedback devices and required work. The controller, axis arrangement and integration scope are selected for the machine after that review.
Is an on-site visit always required?
Existing photos, alarms and records can support the initial review. Whether an on-site evaluation is needed depends on the fault and the available evidence. Location, scope and availability are confirmed before scheduling.
What if the problem is inconsistent bend angles rather than an alarm?
Describe the variation, material, tooling and bend program, along with the machine identity. Use the bending-accuracy guide to organize the information, or select the accuracy problem on the main repair page.
Put the exact fault in front of the service team.
Machine and controller model. Reported issue. Service ZIP. Include the evidence already available.
Planning pathway
Connect the requirement to the complete machine project
Application and capacity
Define material, geometry, thickness or capacity, production volume, quality, workflow, and future work.
Machine and facility
Compare configuration, controller, options, utilities, extraction, footprint, access, unloading, and placement.
Ownership and support
Confirm price path, delivery, startup, training, warranty, service, parts, financing, rental, used, or trade-in options.
