This 20 kN CNC-Stretchbendingmachine is the first model, which has been converted to the new 2020/2021 model year.
Countless improvments ensuring a more productive and better production have been implemented.
Hier a small example of some of the improvements:
- Speeds and accelerations of the CNC axes have been improved
- Percision of positioning and curvature following has been improved
- Digital loadcells ease up alignment, remote operation and analysis of the process with more precise live values.
- Degree of freedom for several axes has been imrpoved (horizontal and vertical swivel, as Z-Axes and Rotation axes).
- Servo Hydraulic axes ahve been replaced by servo electric axes, where possible
- Free-Follow Mode in horizontal and vertical direction is still available
- Valves, cabinets, cables, hoses have new alignments and optimized installation for better accessibility.
- Covers for components, spindles, axes with additional protection for dust, dirt and mechanic impact
- sensors are more accessible
- automatic or manual lubrication can be installed
- Breakers are digital and can be read in the diagnose screen with live values
- More sensors and components conencted by bus sytems to reduce electrical contacts
- Operating interfache with touchscreen and optional graphical surface for easer operation and diagnosis.
- All machine parameters and sensors can be read ab diagnosed by remote access.
- quicke installation on site due to less components in delivery and reduce machine height.
These are only a few of the integrated new advantages of the new generation. Talk to us!
