What problems typically occur with CNC roll bending machines?

Various roll bending machines are frequently used for profile processing. Among the many roll bending machines available, CNC roll bending machines stand out due to their "fully automatic" and "numerical control" advantages, making them one of the most widely used types. However, CNC roll bending machines inevitably encounter various problems during use, affecting their operation. Below, we will introduce some of the most common problems encountered with CNC roll bending machines.

What problems commonly occur with CNC roll bending machines?

1. Insufficient hydraulic pump capacity. Due to prolonged use, the internal components of the hydraulic pump experience wear, leading to a decrease in volumetric efficiency. This significantly increases the load on the fuel tank, and the pressure it needs to withstand also increases, resulting in increased leakage. Increased leakage, in turn, increases the speed at which the pump delivers oil to the cylinder, affecting operation.

2. Inaccurate connection between the coupling and the hydraulic cylinder and the load. Inaccurate load connection will cause the cylinder speed to slow down. This is crucial for fully automatic CNC roll bending machines and must be avoided.

3. Hydraulic cylinder layout issues. Because the piston end face of the roll bending machine is tightly pressed against the cylinder end face, insufficient piston bearing area during startup will result in insufficient load, causing the hydraulic shearing roller speed to slow down. Generally, this problem is caused by insufficient preparation before startup.

These are some common problems with fully automatic CNC roll bending machines, and we need to pay close attention during use.
