04 litres of refrigerant; And be cut in microtherm getting and in tap, the wastage of refrigerant wants a few less, because add man-hour cutting tool,be surrounded to be inside workpiece. Treatment of cooling low temperature is returned inside can lubricate with the minimum of exterior feed flow (MQL) the technology is amalgamative use, in order to reduce the attrition of cutting tool and conglutinate. Because,this is, the target that microtherm machines is to reduce the cutting tool that causes by heat in metal cutting to wear away, but can not have lubricant effect, because this needs have the aid of at MQL technology. MQL can prevent what cause because of cutting tool overheat and bate effectively to wear away accelerate. In although processing technique of this kind of low temperature still is in,developing a process, but introduce according to MAG company, apply iron of Mo Zhu of squirm of this technology milling (CGI) when, can make the cutting rate of hard alloy cutting tool rises 60% , make get together brilliant diamond (PCD) the cutting rate of cutting tool rises 3 times. This company designs vice-president Doug Watts to say, "Lubricate through adscititious MQL, can make the cutting rate of hard alloy cutting tool rises 3 times original, but the cutting rate of PCD cutting tool already was rising the foundation of 3 times to go up to did not see rise again. These cutting experiment to pay close attention to cutting speed mainly rise, and cutting tool life maintains going up with the same standard when using groovy cooling fluid. " Georgiou points out, when use MQL is lubricant, the cutting speed of PCD cutting tool does not have the matter that raises further to depend on, compare with hard alloy photograph, PCD exceeds hard data this kind more wear away not easily, and conduct heat effectively. When with about when the cutting speed of 100m/min processes nonferrous metal data, heat in metal cutting can make PCD is decomposed normally be carbon and invalidation. In microtherm treatment, diamond still can maintain its function stability below higher cutting rate. Besides iron of squirm Mo Zhu, MAG still undertook to titanium alloy and stainless steel microtherm machines an experiment. Georgiou says, "In aviation manufacturing industry will have extensive capital investment henceforth. As use more and more aviation data, titanium alloy not only cutting sex is bad, and diathermancy is very poor also, but we achieved very right result with microtherm technology treatment. " MAG company plan, in its the provider on the machine tool is tasted before changing microtherm to machine main shaft, this skill will be shown on IMTS exhibition, offer the microtherm treatment that is used at transforming a machine tool to rotate to its partner and user package, make they can compare the use result of microtherm treatment and groovy treatment system.
