Why this machine
Asymmetric pre-bending
The rolls are laid out so the plate ends can be pre-bent and flat ends kept to a minimum.
Cones as well as cylinders
Adjustable rear roll for full circles, half circles and conical shapes.
Deflection compensation
Built to keep pressure even along the rolls for consistent results and less scrap.
Standard equipment
- Hydraulic drive
- Three rolls with asymmetric pre-bending
- Cone-bending capability
- Control panel
Options
- Digital readouts or NC control
