CNC cutting machine is a plate furniture enterprise into the modern, CNC production of intelligent equipment, the use of and after the use of maintenance is also particularly important, some of the usual operation errors, for a long time, caused damage to the equipment, maintenance, in addition to mechanical, electrical equipment inspection, adjustment, fastening, the important work is lubrication, Here we will discuss with you how to do the lubrication work in the maintenance of CNC cutting machine.

There are two commonly used lubrication methods of CNC cutting machine, automatic lubrication and manual lubrication. Then, what should we pay attention to when lubricating CNC cutting machine? The selection of equipment lubricating oil, according to the working conditions of the machine, the working environment, the specific characteristics of the friction surface and the different lubrication methods, the types and brands of lubricating oil are not the same. The equipment with high speed and strong ability to form oil wedge should use lubricating oil with low viscosity. When the load per unit area of the friction surface of the equipment is large, large viscosity and good oil should be selected. When the working temperature of the equipment is high, lubricating oil with high viscosity, high flash point, good oil and strong stability or lubricating grease with high drop point should be used;The smaller the gap between the friction surfaces of the equipment, the lower the viscosity of the selected lubricating oil should be; The more rough the friction surface is, the greater the viscosity of the selected lubricating oil should be, and the smaller the working taper of the selected grease should be. In pressure cycle lubrication, the oil temperature is higher, and the lubricating oil with higher viscosity should be used. The lubricating oil of different equipment is selected strictly according to the above principles and experimental results.

Common work several work errors:

1. Blind addition to the accident, in fact, lubrication is not so simple, it is a comprehensive use of fluid mechanics, solid mechanics, materials science, applied mathematics, physical chemistry and other basic theories, to study the principle of lubrication, lubrication materials and lubrication methods, control harmful friction, wear and tear of a science, refueling is just a link in the lubrication.

2. Excessive addition of more harm than good, the selection of equipment lubricating oil, according to the working conditions of the machine, the working environment, the specific characteristics of the friction surface and the different lubrication methods, the selection of lubricating oil type, brand is not the same.
