The characteristics and use conditions of the lubrication of the gantry milling machine

The main parts and components in the gantry milling machine are mostly typical mechanical parts, which are standardized, universal, and have a high degree of serialization. For example, the conditions of sliding bearing and rolling lubrication are different. At 0°C, bearings, gears, worm gear pairs, rolling and sliding guide rails, screw transmission pairs (screw nut pairs), clutches, hydraulic systems, cams, etc. are often used. Warm methods, Make the ambient temperature higher than 5-10°C. High-precision gantry milling machines require a constant temperature air-conditioning environment, generally around 20°C. However, emulsification and deterioration, rusting of mechanical parts, etc., make the rubber seals expand and deform, and cause bubbles and peeling of the paint coating on the surface of the parts. Therefore, consider the adaptability of oil and lubricating coolant, rubber seals, paint materials, and preventing oil leakage. Especially with the gantry milling machine, the requirements for the use of self-cooling fluid are stricter.

1. Low-viscosity lubricating oil, while the latter needs to be lubricated with an oil bath or pressure circulating lubrication system, the use of higher-viscosity oil lubricating The lubrication/cooling general oil is used on the CNC gantry milling machine, which can be used as a lubricating oil and as a lubricating cold bearing. The requirements for lubrication methods and lubricants are very different. The former needs to be lubricated with oil mist or oil/gas lubrication system, using smoother coolant,

2. The working conditions of the gantry milling machine: different types of machine tools with different specifications and sizes, even on the same type of gantry milling machine, due to the different conditions of the processed parts, the rubber working conditions are very different. The requirements for lubrication are different. For example, the adaptability of the grinding wheel spindle bearings of high-speed internal grinders to the heavy-duty seals and paint materials of heavy-duty machine tools: lubricating coolant is used on most gantry milling machines. In the lubricating oil, the oil is often mixed with coolant. Pinyu

3. The environmental conditions of the gantry milling machine: the gantry milling machine is usually installed in an indoor environment. The maximum ambient temperature in summer is 40℃, and the temperature in winter is lower than a lot. The precision requirements and automation of the gantry milling machine are relatively high. Oil viscosity, oxidation resistance (service life) and oil cleanliness.
