Precautions for lubrication of CNC cutting machine equipment

As we all know, not only the quality of CNC machinery and equipment must be excellent, but the maintenance during and after use is also very important. Many operators are not familiar with maintenance, and there are often misunderstandings in some daily habits. After a long time, they often cause damage to the equipment. Maintenance is important in addition to the inspection, adjustment, and fastening of machinery and electrical equipment. It is lubrication.

1. Blindly add lubricating oil

Lubrication is not so simple. It is a science that comprehensively uses basic theories such as fluid mechanics, solid mechanics, materials science, applied mathematics, and physical chemistry to study the principles of lubrication, lubricating materials and lubrication methods, and control harmful friction and wear. Lubricating oil is only one part of lubrication.

The lubrication of a piece of equipment actually starts from its design stage, and it runs through the entire service life of the equipment.

2. Excessive addition will do more harm than good

This is not the case. Simply put, people add lubricating oil between the two friction surfaces in order to form a thin film of oil on the two friction surfaces to avoid direct contact, thereby reducing wear.

However, considering some side effects of adding lubricating oil, strictly control the amount of oil added. For example, in a reducer, in order to reduce the resistance of the gear movement and the temperature rise of the oil, the depth of the gear immersed in the oil should be 1 to 2 teeth height. The amount of fuel for high speed should be less.

3. Add lubricating oil at will

The choice of equipment lubricants depends on the machine's working conditions, working environment, specific characteristics of the friction surface, and different lubrication methods, and the types and grades of the selected lubricants are also different.For equipment with high rotation speed and strong forming effect, lubricating oil with low viscosity should be selected; when the load per unit area of the friction surface of the equipment is large, lubricating oil with high viscosity and good oiliness should be selected;When the working environment temperature of the equipment is high, lubricating oil with higher viscosity, higher flash point, better oiliness, and stronger stability or grease with higher dropping point should be used;

The smaller the gap between the friction surfaces of the equipment, the lower the viscosity of the lubricating oil should be; the rougher the friction surface, the greater the viscosity of the lubricating oil should be, and the smaller the working taper should be if the lubricating oil is selected; the oil temperature is higher in the pressure cycle lubrication , Lubricating oil with higher viscosity should be used.

Lubricants for different equipment are selected strictly according to the above principles and experimental results. Under normal circumstances, it cannot be replaced. If it is replaced arbitrarily, it will destroy the lubrication environment of the equipment, cause the equipment to wear and tear, and cause economic losses.
