Problems about the newly purchased and use of the CNC shearing machine?

The maintenance work of the new CNC shearing machine includes:

(1) The oil change should be carried out after the equipment has been working for one month for the first time, and then once a year after that. In addition, when changing the oil, the oil tank must be cleaned at the same time.

(2) The brand of hydraulic oil used should be determined according to the actual situation.

(3) Pay attention to the system oil temperature at all times. Normally, it should be within the range of 35℃-60℃, and the maximum should not exceed 70℃.

(4) The filter must be thoroughly cleaned while replacing the oil.

(5) After using the equipment for one month, check whether there is any deformation at the bend of the tubing.

What problems will occur in the maintenance work of the newly purchased CNC bending machine and the use of the CNC shearing machine?

CNC shearing machine

The problems that Anhui Yongya has in the oil change of CNC shears are mainly manifested in three aspects?

First, for parts that use high-viscosity lubricating oil, if you change the oil to low-viscosity lubricating oil at will, it will affect the sealing performance of the corresponding box and shaft hole to a certain extent, and sometimes greatly reduce the sealing performance of these parts. .

Secondly, if the oil tank is not cleaned when changing the oil, the dirt in the oil tank may enter the lubrication system, block the oil circuit, wear the seals and cause oil leakage.

Third, the oil is added too much when changing the oil, especially in the parts with rotating parts, because of the stirring effect of the rotating parts, oil spills are more likely to occur.

Hydraulic shearing machine tool material requirements:

1. The bonding temperature of anti-adhesive cemented carbide is higher than that of high-speed steel, so it has higher resistance to adhesion and wear resistance.

2. Hardness: A lot of hard carbides are contained in the near-hardness. Its hardness is much higher than that of high-speed steel. The higher the near-hardness, the better the wear resistance.

3. Toughness The toughness of cemented carbide is much lower than that of high speed. It is not suitable for use under strong impact and vibration.

4. Thermal physical properties The thermal conductivity of cemented carbide is higher than that of high-speed steel.
