What issues should Manhart (Guangdong) CNC Machine Tool Co., Ltd. pay attention to when maintaining and calibrating CNC rolling and bending machines?

When maintaining and calibrating CNC rolling and bending machines, the following key issues need to be noted:
Firstly, it is necessary to follow the maintenance manual and guidelines provided by the manufacturer to ensure correct maintenance steps and cycles. This includes regular oil replacement, cleaning of oil circuits and cylinders, replacement of sealing rings, etc., to prevent problems such as stuck valves and oil circuit failures. For various components of the CNC rolling and bending machine, such as gear sets, ductile iron friction surfaces, thrust motor fixing screws, and spindle screws, regular lubrication, tightening, and inspection are also required to ensure their normal operation.
Secondly, special attention should be paid to the maintenance of the electrical components during the maintenance process. The electrical box needs to be regularly cleaned of dust to prevent dust accumulation and electrical failures. At the same time, it is necessary to keep the surface of the machine clean and tidy, avoid stacking debris and tools, and ensure the normal heat dissipation and operating space of the machine.
In addition, for the calibration of CNC rolling and bending machines, professional metrology personnel and laser calibration instruments are required for operation. During the operation, it is necessary to open the machine cover and adjust the optical components on the workbench, spindle, and tripod. Due to the fact that the trajectory of the measured target’s movement may not be straight, it is necessary to use a laser interferometer that is not affected by large lateral movements to ensure the accuracy of calibration. At the same time, for situations where quality needs to be carefully balanced, the calibration and compensation process may affect the production cycle, so it is necessary to plan and arrange in advance.
Finally, it should be emphasized that maintenance and calibration work should be carried out by professionally trained personnel to ensure the correctness and safety of operations. During the operation process, safety operating procedures should be strictly followed, such as wearing protective goggles, gloves, etc., to prevent accidents from occurring.
In summary, the maintenance and calibration work of CNC rolling and bending machines requires comprehensive consideration of multiple aspects, including the maintenance of mechanical parts, cleaning of electrical parts, and accuracy of the calibration process. By proper maintenance and calibration, the long-term stable operation and high-precision machining capability of the CNC bending machine can be ensured.
