The micro-lubrication technology can bring good economic and environmental benefits, because in the crankshaft oil hole processing, only a very small amount of lubricating oil is needed to achieve a good lubrication effect, so that the factory can obtain a considerable amount of lubrication technology. The economic benefits. Crankshaft machining center through the spindle and internal cold drilling, the effective transmission of oil mist to the cutting area, the control system of the machine tool is connected with the micro-lubrication device, in accordance with the requirements of the processing process by changing the ball valve opening frequency and the drill hole channel size to automatically adjust the lubrication The amount of oil mist transported.
The application of the micro-lubrication technology for machining crankshaft oil holes has the following advantages:
(1) The oil mist can penetrate into the friction point and play a good lubrication effect;
(2) In deep hole machining, the compressed air velocity can carry away the heat of cutting, and a large amount of cutting heat is carried away with the chips.
(3) low oil consumption, cutting friction points always maintain a proper amount of reliable lubrication;
(4) The product is small in size, low in gas consumption, and simple in operation;
(5) Reduce the maintenance costs and operating costs of the machine tool.
Minimal lubrication machining crankshaft oil hole
The micro-lubrication technology is a new lubrication technology that makes the processing process more efficient, energy-saving and clean. It can greatly increase the production efficiency in the machining process of the crankshaft oil hole, and the cutting tool life can be increased by more than 50% and a clean workshop environment can be obtained. . The micro-lubrication technology is a lubrication method that uses compressed air as the driving force to atomize a small amount of lubricating oil into micron-sized suspended oil particles and deliver the suspended oil particles to the cutting area. In contrast to the traditional splash-type lubrication method that uses a large amount of cutting fluid or cutting oil, only the spray lubrication cooling is provided during cutting, so that there is less lubricant left on the chips and the workpiece, and residual lubrication with the spraying method. Compared to oil, it is very slight. The production plant uses a small amount of lubrication technology to process the crankshaft oil hole, and can obtain higher production efficiency, leading the development of the micro-lubrication technology to adapt to changes in market demand.
