Advantages of 4-roller plate rolling machine
1. Fully hydraulic drive, efficient and energy-saving (driving power equivalent to 60% of traditional)
2. Permanent lubrication technology (no need for oil during bearing life)
3. Adjustable clamping pressure (no slipping, production efficiency 50% -80% higher than the three roll bending machine)
4. Can roll a cylinder with a diameter of 1.1 times the diameter of the upper roller
5. It can meet various rolling requirements.
The following users are suitable for using a four roll bending machine
1. Users who are using a rolling machine for the first time, as it is an easy to operate rolling machine
2. Operators lack experience and require high productivity
3. Require high precision and improve quality
4. I hope to use only one operator to reduce labor costs
5. Due to the large size of the board, high production volume, or safety reasons, handling devices, feeding devices, and supporting devices are required
6. I hope to use CNC operation to reduce the operational level of operators and other factors.
