Minimal lubrication for machining oil hole of automobile crankshaft

<strong>Minimum lubrication technology is</strong> a new lubrication technology that makes the machining process more effective, energy-saving and cleaner. It can greatly improve production efficiency and increase the life of cutting tools by 50% during the machining of crankshaft oil holes. Above and get a clean workshop environment. <strong>Minimum Lubrication</strong> technology is a lubrication method that uses compressed air as power to atomize trace lubricating oil into micron-level suspended oil particles and transport the suspended oil particles to the cutting area. It is completely different from the traditional spray lubrication method that uses a large amount of cutting fluid or cutting oil: only spray lubrication cooling is provided during the cutting process, then there is less lubricating oil left on the chips and the workpiece, and the residual lubrication of the spray method Compared to oil, it is very small. Production plants use <strong>micro lubrication technology</strong> to process crankshaft oil holes, which can achieve higher production efficiency and lead the development of micro lubrication technology to adapt to changes in market demand. <br /> <strong>Minimum lubrication</strong> technology can bring good economic and environmental benefits, because in crankshaft oil hole processing, only a small amount of lubricating oil is needed to achieve good lubrication effect. So that the factory can obtain considerable economic benefits after using the <strong>micro lubrication</strong> technology. The crankshaft machining center quickly transports the oil mist to the cutting area through the main shaft and the internal cold drill. The control system of the machine tool is connected with the <strong>minimal lubrication</strong> device, and the opening frequency of the ball valve and the inner hole of the drill are changed according to the requirements of the processing technology. The size of the channel can automatically adjust the delivery volume of the lubricating oil mist. Micro-lubrication</strong> technology applied to machining crankshaft oil holes has the following advantages:<br />
(1) The oil mist can penetrate into the friction point and play a good lubrication effect;<br />
(2) In deep hole machining, the compressed air flow rate can take away the cutting heat, and a large amount of cutting heat is taken away with the chips. <br />
(3) The oil consumption is low, and the cutting friction points always maintain an appropriate amount of reliable lubrication;<br />
(4) The product has small volume, low gas source consumption and simple operation;<br />
(5) Reduce the maintenance cost and operating cost of the machine tool. <br />
