Its special helix angle of 40 to outline UFL greater angle, and through narrow discrepancies in the actual and strong inverted cone achieve relatively low friction, but also has a special channel profile can be a good Paixie , and can guarantee low friction mobile chip. At the same time it through the use of a higher cobalt content in micro-grain carbide, in the process can also be used to provide high reliability. Although it can be fully expect in the future use of stem cutting, but to completely dry cutting, in the tool life, precision machining, surface roughness, there are still many problems to be overcome, so it can be predicted, according to the current switch to the status quo not cutting fluid impact on the environment, on the cutting fluid appropriate, as well as to trace the sentinel, such as oil. In many applications now, we have a high amount of lubricating fluid jet cutting to the knife's edge, with high lubricity through the cutting fluid and the correct cutting fluid supply and trace the oil installations to the combination of a micro-lubrication was the semi-Cutting processing. Through the use of micro-lubrication technology, we in the Cutting on the use of cutting fluid has been in the past few liters per minute decreased to the current several milliliters per hour, less than the traditional cutting of the use of 1:100,000. Therefore, no longer needed the anti-corruption cutting oil concentration management, parts cleaning as cutting oil consumption and little can be simple, because the chip drying, so that the collection, processing or melting are easier.
