Overview
The F7 flange-forming machine has its own hydraulic system and electrical control. Push-button control offers jog and linked operation, and pressure and stroke are adjustable within the rated range. It replaces the old process of cutting plate, butt welding, straightening and turning, saving oxygen, acetylene, labour and material. It is the core machine for flange manufacturing.
Key features
- Three units: main machine, hydraulic station and electrical control cabinet.
- High-pressure oil drives a hydraulic motor for torque and a cylinder for thrust.
- Displacement sensor with digital display for accurate, repeatable feed.
- Heat-treated 40Cr shafts, forged bevel gears and dies for long service life.
- No upper limit on rolling diameter for any listed material.
