Lubrication And Maintenance Of Lathe
Nov 27, 2017

The lubrication method of the machine tool and the choice of lubricating grease are based on the structure of the machine, the degree of automation, the working condition of the machine tool and the requirement of the precision, the machine tool lubrication should try to avoid the temperature rise and vibration at the same time of reducing the consumption. Machine tool as a complex and sophisticated machine, will use a variety of transmission devices, according to the type of equipment, working environment and the required precision requirements on the viscosity of lubricants, oil oxidation resistance, resistance to extreme pressure performance and other related properties have different requirements.

Lubrication Method Requirements

1. The lubrication point of machine tool is many and complex, and there are many machine tools at the same time lubrication, so the use of automatic lubrication, also known as forced cycle lubrication to save manpower, and ensure reliable lubrication. 2. Machine tools rely on hydraulic transmission, in order to simplify the lubrication system, so many of the machine tools are hydraulic and lubrication system common, so to consider in order to ensure that the hydraulic system is working properly at the same time to meet the lubrication of the requirements of each lubricating point. Under the premise of considering the operating cost, we can choose the lubricating oil (grease) with high viscosity index, antiwear property and good oxidation resistance. 3. The lubrication of the guideway and main bearing of a large machine tool usually adopts the lubrication method of gravity refueling (dripping oil and oil core). This lubrication method should consider the fluidity of lubricating oil to ensure that lubricating oil can automatically flow into the friction pair. 4. Large machine tools have many gear drives, sliding and rolling bearings. In particular, the universal grinder has a very complex transmission device, due to friction loss of power to reach $number, so in the selection of lubricants must take into account the appropriate viscosity and good anti-wear lubrication, and strive to minimize friction loss to save power consumption. 5. Roughing machine tools are mostly intermittent work, resulting in impact load and boundary lubrication, so consider appropriate annual, good lubrication performance and resistance to extreme pressure performance. 6. Precision machine tools for the temperature rise of lubricating oil has a very stringent requirements, generally can not exceed room temperature 2-5 ℃, so the oil viscosity and lubrication methods and fuel tank capacity to do a careful calculation and design. 7. Machine tool lubrication system, hydraulic system and each of the friction pairs of seals, will make the processing of metal debris, grinding grains into the lubrication system, not only may clog the circuit caused by wear and can also accelerate the deterioration of oil. Therefore the attention to the system seals is necessary! 8. In the metal cutting, grinding machine for cooling, lubrication tools and processing parts, most of the use of emulsion and in the grinder on the use of sodium phosphate aqueous solution are likely to enter the lubricating oil, promote the degradation of oil and emulsification. Therefore, in the selection of lubricating oil must take into account the oil's emulsifying resistance, water resistance, rust and anti-corrosion. 9. Machine Tool Guide is the focus of lubrication machine tools and difficulties, the movement of the Guide is repeated, and the speed and load changes are very large, easy to appear crawling phenomenon, resulting in reduced processing accuracy or even the machine tool scrap. Therefore, early selection of lubricating oil should be considered appropriate viscosity and good resistance to climb lubricants.
