- Plate Rolls
- HMR-4 Series
Our HMR-4 series 4-roll bending machines have a compact design and robust frames built with high-quality solid steels. The rolls are powered hydraulic cylinders and syncronization controlled with the PLC. The rotation of the top and bottom rolls is powered by an AC motor and helical gearbox. This is an ideal plate roll bending machine for shops that need an easy-to-operate machine using a 4-roll design and working with light gauge materials ranging from 1mm to 6mm. These machines come standard with tiltable side rolls for rolling a cone-shaped parts.
Additionally, changing the top roll on this machine is very easy. For example, you can replace a 130mm diameter top roll with an 80mm diameter top roll in minutes. You won't be stuck when needing to bend thinner sheets with a smaller diameters.
The HMR-4 machine is available in lengths from 0.65m to 2m, making it very flexible for a wide range of applications, so you can get the right machine for your needs.
