First, gear lubrication

The gears of the machine tool the impact and vibration is not big, load is small, and generally do not need to use with extreme pressure additives lubricating oil. Know how to prevent the spindle box of hot deformation, and the shock load larger stamping or shear machine tool gear, should use an anti-wear agent gear oil, for loops lubrication oil or lubrication of gear oil , besides should consider oxidation resistance, and corrosion resistance, abrasion, attend to corrosion and anti-foam . According to the type of gear to choose the appropriate gear oil and suitable viscosity.

Second, guide lubrication

Guide load and speed changes a lot, general guide for the load 3-8 N/cm2, but because the guide frequent repeated movement, it's easy to produce the boundary lubrication, even half dry lubrication and lead to creep phenomenon, in addition to machine tool design and material bad lubrication is the main reason to crawl. In order to overcome creep phenomenon, besides using of fluorine resin guide cover and so on, to improve the lubrication, mainly including the climb dose with the oil.

Third, bearing lubrication

1, rolling bearing the lubrication: rolling bearing in machine tools, because of the small friction coefficient, and quiet operation etc, and thus has a lot on the machine by rolling bearing, 25 mm diameter, speed 30000 r/min the following to use sealing into the fat. More than 30000 r/min, apply to forced lubrication or spray  lubrication. Note that the rolling bearing in addition to large, rough special cases, generally can't use containing solid lubricant of the fat.

 
2, sliding bearing the lubrication: sliding bearings are used in the transmission way, lubricating oil to lubricate role not only to have the cooling role, so need lubricating the good performance of low viscosity lubricating oil, but also need good oxidation resistance, abrasion resistance, excellent rust resistance and resistance of foam. For precision grinding machine millstone spindle of sliding bearings used in precision, for bearing clearance, small (1 micron), particularly high speed (30000 r/min above) should use viscosity is small, anti-wear oily excellent viscosity was 2.0 (40 ℃) oil.
