Problems solved by technology

[0002] Traditional open gears, guide rails, bearings and other open environments that use thin oil lubrication, because external impurities will enter the friction pair, and the wear of the machine itself can greatly shorten the service life of gears, guide rails, and bearings
Micro-quantity lubrication technology is a new type of lubrication technology developed in recent years. It is to use a micro-quantity lubrication system on the metal friction surface to lubricate and cool the friction surface of a micro-quantity lubricating oil with good extreme pressure, anti-wear and lubricity, and solve the problem of traditional lubrication methods. Problems such as large amount of lubricating oil used, large amount of waste and leakage
Micro-quantity lubrication technology Since the micro-quantity lubrication device often uses compressed air as power, a short-term negative pressure can be formed on the surface of the friction pair, which can partially blow off impurities from the outside world. Therefore, it can effectively solve the damage to gears, guide rails, bearings, etc. caused by external impurities and impurities caused by friction. However, for some damaged gears, guide rails, and bearings, the existing micro-lubrication technology has no modification function and cannot repair the damaged parts. to prolong the service life of these parts
