FZH Engineering GmbH Vario Flex

Pipe cutting system with optical laser marking detection

The FZH Vario Flex is a fully automated pipe cutting system.
It is specifically designed for the precise and reliable cutting of stainless steel pipes (e.g., for fuel, brake, air conditioning, or hydraulic lines).
The system features optical laser marking detection.
The control panel allows the user to select whether the cut is triggered mechanically (e.g., at the back of a union nut) or fully automatically via the optical detection of a laser marking applied to the pipe.
Thanks to the integrated rotating 3-jaw cutting head and a micro-spraying unit (minimum quantity lubrication), the process is extremely gentle on the tooling.
The pipes remain almost completely dry and free from major contamination.
The entire process, from loading to clamping, cutting, and unloading, is highly automated and carried out in a material-saving cycle.
Fully integrated labeling & traceability system: The system is designed for modern quality standards (Industry 4.0 / Automotive). After the cutting process, the barcode label is automatically generated, assigned, and printed for complete part traceability (traceability & system logging are directly integrated).
Thanks to two separate box output stations (rear-side airlocks with sliding doors), the system automatically switches to the second station when the first box is full. The removal of the finished KLT boxes takes place in parallel with the main processing time without stopping the machine.
