Key Features
NG 4-Roll Features
Standard features that set this machine apart in demanding manufacturing environments.
Precision & Performance
- Independent servo-hydraulic circuits on every roll deliver extreme positioning precision with no cross-talk between axes
- Single-pass cylinder forming—pinch-and-roll geometry completes a full cylinder without repositioning the plate
- Precision alignment technology streamlines setup and reduces operator intervention between jobs
Ease of Operation
- NextRoll CNC platform provides real-time bending simulation, stored programs, and an intuitive touchscreen interface
- Advanced digital parallelism system continuously monitors and corrects lower and side roll alignment during rolling
- Reinforced yet lighter body frame maintains perfect alignment under heavy loads while reducing overall machine weight
- Full automation and digital integration—program a shape, press start, and the NG handles pre-bend through final pass
- Modular sheet cover design enhances durability while simplifying maintenance and repair access
- Integrated cone bending with position adjustment accessible from the NextRoll control panel
- Hydraulic safety system meets current CE standards for operator protection

4-roll hydraulic plate rolling machine
AHS 4-Roll
Built around a four-roll hydraulic configuration, the AHS handles plate from 2 mm up to 200 mm thick and widths spanning 500 mm to 12,000 mm. Its pinch-and-roll approach grips the workpiece between the upper and lower rolls, completing a full cylinder without repositioning the plate. A planetary lever-arm drive system concentrates bending force where it counts, keeping flat-end waste to a minimum. The working range spans models from compact 1,250 mm units to full-production 6,100 mm lines, with NC or CNC control options depending on your throughput needs. AC Machinery supplies and supports the full AHS range from Cambridge, Ontario.
4-roll wind tower bending line
AHS-RK
The AHS-RK pairs a full AHS four-roll platform with column-boom welding stations and turning rotators in a single coordinated production line. Designed for wind energy fabricators, it moves plate from rolling through longitudinal and circumferential welding without manual handling between stages. The result is shorter cycle times, tighter dimensional consistency, and higher daily output on tower shell sections. Backed by over five decades of Akyapak heavy-rolling expertise, the AHS-RK is supplied and supported by AC Machinery from Cambridge, Ontario.

AHS-AUTO
The AHS-AUTO takes the proven AHS four-roll platform and wraps it in a complete automation package. A pneumatic gantry loader with vacuum lifts pulls plates from the stockpile and transfers them to an infeed conveyor, which feeds the machine automatically. Once the plate is in position, the rolling cycle runs hands-free — forming the workpiece and ejecting the finished part without operator intervention. The result is a continuous non-stop cycle: load, roll, eject, repeat. Because the gantry handles all material movement, there is no need for an overhead crane, freeing up floor space and eliminating a common bottleneck in high-volume shops. Whether you are rolling pressure vessel shells, pipe sections, or structural components, the AHS-AUTO turns plate rolling from a manually intensive process into a push-button production line. AC Machinery supplies and supports the full AHS-AUTO system from Cambridge, Ontario.
