MODERN RETROFIT CONTROL SYSTEM FOR WOHLENBERG CUTTING MACHINES

More safety. More productivity. More future-proofing.
For WOHLENBERG cutting machines

Types 92 – 220 PRT / SPM / MCS / CutTec

Give your WOHLENBERG a new lease on life.

Even after many years of operation, your Wohlenberg cutting machine still features robust and precise mechanics. However, the real challenges are often outdated control components, unavailable spare parts and increasing machine downtime.

With the GraphiTech Retrofit System, your machine receives a completely new electrical and electronic control system based on modern industrial technology.

Your benefits:

✓ lower investment costs compared to purchasing a new machine
✓ state-of-the-art safety and control technology
✓ long-term availability of spare parts
✓ improved ease of operation
✓ minimal machine downtime during the retrofit
✓ significantly extended machine service life

Retrofit directly at your site

The retrofit system was specifically developed for Wohlenberg cutting machines. The complete retrofit is usually carried out at your site within just a few days. This minimizes production downtime and gets your machine back into operation quickly.

State-of-the-art control technology

At the heart of the system is a robust 10.1” color touchscreen with an intuitive user interface.
The new control system replaces the existing electrical and electronic control components, bringing your machine up to current technological standards.

The new control system includes:

  • 10.1” widescreen touch panel
  • new control cabinet mounting plate
  • modern PLC control system
  • new safety components
  • new AC/DC power supply
  • completely new cable set
  • new switching and touch sensors
  • safety light curtain on the operator side

All existing actuators, such as motors, valves and clutches, are retained. This significantly reduces the investment costs. The control system complies with the requirements of DIN EN 12643-3 for cutting machines.

New control cabinet mounting plate

The completely rebuilt control cabinet is equipped exclusively with modern industrial components with long-term spare parts availability.

Benefits:
✓ increased operational reliability
✓ reduced downtime
✓ easy maintenance
✓ long-term spare parts availability

Modern Safety Light Curtain

The operator side is monitored by a modern safety light curtain.
The operator side is monitored by a modern safety light curtain.
This reliably protects the operator and ensures that the machine meets current safety requirements.

For the optional “VA – Fully Automatic Cutting Mode”, an additional monitoring unit is installed.

Precise Knife Position Monitoring

Robust position switches and a high-resolution incremental encoder monitor the exact knife position during every cutting cycle.

This ensures:
✓ safe cutting operations
✓ reproducible cutting results
✓ high process reliability
✓ reliable continuous operation

Recommendation for the Safety Bolt

On machines without a mechanical safety bolt, its function is simulated by the safety control system.
Since the mechanical safety bolt is an essential safety component, we recommend retrofitting it.

Intuitive Operation and Powerful Features

The Touch Panel

The modern 10.1” touch panel is the central operating interface of your cutting machine.
All functions are conveniently operated via the touchscreen.
No separate keyboards.
No worn-out function keys.
No complicated program labelling.
The clear and intuitive user interface allows operators to become familiar with the system quickly and helps reduce operating errors..

Good for Your Business. Good for the Environment.

Why scrap a functioning machine when its robust mechanics can continue to operate reliably for many years?

With the GraphiTech Retrofit System, you benefit from state-of-the-art control and safety technology while retaining the machine’s robust mechanical structure.

This eliminates the need to manufacture a new machine frame from several tons of cast material, as well as numerous energy-intensive manufacturing processes.

This not only reduces investment costs, but also avoids significant CO₂ emissions.

Retrofit is therefore not only an economical choice – it is also an active contribution to greater sustainability.

Extend the service life of your machine by many years.
