How to maintain the hydraulic oil circuit of the CNC bending machine

Before the CNC bending machine is maintained or cleaned, the upper die should be aligned with the lower die and then turned off until the work is completed. If you need to start or perform other operations, select the manual mode and ensure safety. The maintenance content is as follows:

Maintenance of hydraulic oil circuit of CNC bending machine and how to grasp the precision of CNC shearing machine

CNC bending machine

hydraulic circuit

A. Check the oil level of the oil tank every week, if the hydraulic system is repaired, it should also be checked. If the oil level is lower than the oil window, add hydraulic oil;

C. The oil should be changed after the new machine has been working for 2000 hours, and the oil should be changed after every 4000 to 6000 hours of work thereafter, and the oil tank should be cleaned every time the oil is changed;

D. The oil temperature of the system should be between 35℃～60℃ and not exceed 70℃. If it is too high, it will cause deterioration and damage of the oil quality and accessories.

filter

A. Each time the oil is changed, the filter should be replaced or thoroughly cleaned;

B. The machine tool has related alarms or other filter abnormalities such as unclean oil, and should be replaced;

C. The air filter on the fuel tank should be inspected and cleaned every 3 months, preferably 1 year.

Hydraulic parts

A. Clean hydraulic components (substrates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system, and cleaning agents cannot be used;

B. After using the new machine for one month, check whether there is any deformation in the bends of the oil pipes. If there is any abnormality, they should be replaced. After two months of use, all fittings should be tightened.

Precision inspection of CNC shearing machine:

Hydraulic shearing machine is different from manual shearing machine. It mainly eliminates vibration stress through hydraulic components, making the accuracy of the components more accurate.

Generally we need to check the following aspects:

Is the hydraulic system of the hydraulic shearing machine working in a normal state? Is there any abnormality in the hydraulic pump?

The last time the hydraulic oil was checked for cleanliness and the result of the cleaning and replacement of the filter element; if there is a failure, whether some hydraulic components have been adjusted before the failure.
