Common faults of back gauge of 8 axis press brake

8 axis press brake is one of the commonly used equipment in modern manufacturing industry, and the back gauge device is one of its key parts. However, due to various reasons, various failures may occur in the back gauge device, affecting the normal operation and processing accuracy of the equipment. Below we will introduce in detail the common faults of the back gauge of CNC press brakes and their solutions.

The flexibility of rear gauge shaft movement decreases for 8 axis press brake

The reduced flexibility in movement of the rear gauge shaft may be caused by wear of the sliding surface due to long-term use, cylinder leakage, or poor lubrication. In this case, it is necessary to check the sliding surface and repair the wear, replace the sealing ring or adjust the oil circuit, and ensure good lubrication.

The positioning accuracy of the back gauge is unstable for 8 axis press brake

Unstable positioning accuracy of the back gauge may be caused by poor parallelism between the back gauge shaft and the guide rail, instability of the back gauge transmission system, electrical or control system failures, etc. It is necessary to check the parallelism between the rear gauge shaft and the guide rail, adjust the transmission system, check the electrical and control systems, and troubleshoot.

Axial movement of the rear gauge shaft for 8 axis press brake

The axial movement of the back gauge shaft may be caused by low installation accuracy of the back gauge device, damage to the bearings of the back gauge shaft, or unbalanced transmission system of the back gauge. It is necessary to readjust the installation accuracy of the rear gauge device, replace damaged bearings or adjust the balance of the transmission system.

The running speed of the back gauge is uneven for 8 axis press brake

The uneven running speed of the back gauge may be caused by instability of the hydraulic system, leakage in the cylinder, or blockage of the oil circuit. It is necessary to check the hydraulic system, adjust the cylinder sealing ring or clean the oil line.

Abnormal noise from the transmission system of the rear gauge for 8 axis press brake

Abnormal noises in the transmission system of the rear gauge may be caused by damaged gears or chains in the transmission device, damaged bearings, or poor lubrication. Gears, chains and bearings in the transmission need to be inspected, damaged parts replaced and good lubrication ensured.

To sum up, the common faults of the back gauge of CNC press brakes include the reduced flexibility of the movement of the back gauge shaft, unstable positioning accuracy of the back gauge, axial movement of the back gauge shaft, and the operation of the back gauge. Uneven speed and abnormal noise in the transmission system of the rear gauge. For different faults, corresponding measures need to be taken to repair and adjust to ensure the normal operation and use of the equipment. At the same time, strengthening the maintenance and upkeep of equipment is also an important measure to prevent failures.
