The advantage that compounds cutting oil is in the United States, a lot of workshops that manufacture cutting cutting tool, a few years ago firm the cutting fluid grinding machine of numerical control tool by water base the pure mineral oil that emulsion instead refines by crude crude oil, should change this kind of pure mineral oil again now for artificial complex cutting is oily, its reason is to synthesize cutting oil to compare standard mineral oil to have more advantages. For example, the report says, the lubricant function that synthesizes cutting oil is mineral cutting oil respectively 5 times and 10 times of fluid of water radical cutting; In addition, their evaporate rate is slower than mineral oil 60% , meet scarcely loss, also won't cause a bacterium, can avoid a cobalt and carbide from the soak in hard alloy cutting tool. The lubricant performance with high  can prolong the life of emery wheel, prevent quantity of heat to pass into workpiece, gain the bright and clean treatment face that does not have break thereby. Use mineral oil can have prolonged emery wheel life 50% , and synthetic cutting oil is more, the job shops of cutting tool grinding of emery wheel of this offset bad news is very beneficial, because the price of an emery wheel can be as high as 10 thousand dollar.  applies fluid of water radical cutting to make much quantity of heat sends work, and synthetic cutting oil follows quantity of heat grind bits to be swept together. Water brings about boiling likely in absorbing process of quantity of heat effectively, form vapour, cannot have cooling effect thereby, and oil is won't boiling.  cutting oil includes to synthesize cutting oil and mineral oil to apply to tool grinding machine, they can lubricate the attrition of the machine tool deputy, do not damage slideway, do not make a spare parts rusty, and won't generate when grinding hard metal " black layer " .  " if use inferior the filter of micron maintains cutting fluid cleanness, so the service life that synthesizes cutting oil can be achieved and grow like machine tool life " , the company president that cent sells oil of cutting of pure synthesis of SintoGrind of German Oel-Held company (PeterKnowles) says so.  SintoGrind by get together Alpha olefin (PAOs) is made, about 4 companies produce PAOs, it is the reaction since a gas mixture and activator, complex falls in high temperature high pressure a kind of liquid.  because its molecular structure, PAOs liquid is pure, do not contain the molecular catenary that does not need, wait like balmy hydrocarbon and balmy cyclic hydrocarbon. These are found in the mineral oil that the element is producing by crude oil however, although be passed 2 times or 3 fine, still put in the molecular catenary with not stable move in all mineral oil, they can be interrupted below the high temperature high pressure in grinding, make oil degenerative gradually thereby, the workshop must change regularly cutting is oily.  SintoGrind basically is used at hard alloy of grinding of high speed of diamond emery wheel, high-speed steel and stainless steel, apply to the tool grinding machine of cutting tool of production hard alloy especially, because of it won't soak carbide arrives worry bit in, make handlers won't touch these harmful material. Besides having profit to the machine tool, this kind of oil is advantageous also to handlers, because it does not contain pesticide, do not cause bacterium, fungus and zymogenic, also won't generate those who cause cancer inferior nitric acid amine.  has to handlers is returned advantageously, sintoGrind produces bubble or oily mist scarcely, and the water that fluid of water radical cutting has 95% to use a workshop, only minority is used outside supply water. Bubble of soft water easy generation, and hard water is mordant.  although SintoGrind is complex, but still be a hydrocarbon, if have enough quantity of heat, can cause inflammation, its burning point is very fortunately high. The requirement nowadays great majority to the machine tool uses oil of  use cutting when the tool grinding machine with synthetic mineral or oily cutting works, the machine tool should close completely, include a few necessary unit, be like instrument of device of pump device, put out a fire, flow control and the spare parts of use oil resistant. Oil gas of eduction of  pump device, oily mist and lampblack, stimulate handlers in order to prevent them. To make discharged air does not pollute an environment, the system needs to deploy guider, screen pack, electrostatic filter system and active carbon filter; The workshop that configuration has the central system that discharge wind should use disappear mist implement undertake filtering to air.  pump valve installs the coping in the machine tool, in case produce explosion, it can release energy, next valve can be shut automatically, stop pump. In addition, because oil is but flaming, grinder should provide unit of automatic put out a fire. To prevent explosive possibility, must add oil 2 ～ 3 atmosphere drench via many nozzle gush emery wheel and workpiece. Once oily discharge is not offerred,go up, flow control appearance can stop immediately machine. After configures oil level controls appearance to be able to prevent air of the interfuse in oil, be reached by pump emery wheel, workpiece contacts an area. Of switch of the tube of the machine tool, cable, sealing ring, journey plastic and the balata inside grinding area should be oil resistant. The cutting fluid that compares water radical because of oily thermal capacity is small, answer because of the oily flow that this uses double, if use the pump of same discharge, must configure the cooling device of cutting oil.
