Content summary: Because have good heatproof concussion sex, brilliant must increase model cutting tool of pottery and porcelain can be used at working to cut, wet cut or intermittent and cooling and need not fear collapse knife perhaps produces hot tearing. The any crystalline substance that takes coat must increase model pottery and porcelain fits those need very much longer of cutting tool life, successive half essence and finish machining and similar be spent gently and moderate strength treatment. Cutting tool of pottery and porcelain suits to machine alloy of hard steel of temper by dipping in water, heat-resisting or high temperature alloy very much. Handlers often erroneously the treatment means of hard alloy of continue to use, this plants their need unlock " hard alloy complex " , turn and consider the special requirement that cutting tool of pottery and porcelain machines: Choose the tigidity of proper bit form and machine tool, arbor and clamping apparatus according to processing data. High temperature is the main enemy that hard alloy machines, accordingly, major handlers can lower cutting rate and raise feed rate, reduce main shaft rotate speed further when the meeting when the situation is bad. But this kind of treatment means just that suits hard alloy most is the biggest contraindication in treatment of cutting tool of pottery and porcelain, because cutting speed inadequacy and feed had been led,the major problem that in be being machined because of cutting tool of pottery and porcelain, encounters is big and bring about. High temperature is different from hard alloy to the action of pottery and porcelain. Be gotten on in face of the knife before cutting tool by the material of cutting in cutting process cut area to be pushed to leave, heat in metal cutting also builds up in this area. As the addition of cutting speed, the quantity of heat that cuts area place generation cannot be taken away by useless bits inside short time, can form high temperature thereby and produce bate effect. The melting point of hard alloy is 1199 ℃ about, high temperature causes matrix of hard alloy razor blade very easily be out of shape and damage. Reduce cutting speed to often can assure the reasonable life of hard alloy razor blade so. And the melting point of material of pottery and porcelain is as high as 1999 ℃ , accordingly, the high temperature of the generation in high speed treatment is advantageous instead to razor blade of pottery and porcelain. The speed of the razor blade of the most appropriate hard alloy of cutting speed outclass of razor blade of pottery and porcelain, the high temperature effect of the generation when high speed cutting can make be machined material bate, reduced the resistance when cutting greatly thereby. Accordingly, choose below coequal condition opposite at hard alloy razor blade for razor blade of flimsier pottery and porcelain, can achieve the cutting result with hard alloy similar razor blade easily. Use cutting tool of pottery and porcelain to be able to lead material purify sometimes from minutely hundreds feet rise minutely thousands of feet. Appropriate cutting rate and the tie-in meeting that feed leads are in those who cut area to make an ideal, the environment that fits razor blade of pottery and porcelain. But reduce main shaft rotate speed to be able to make cutting tool produces scintilla -- the invalidation that brings about bit and cutting tool. The material of razor blade of pottery and porcelain qualitative, coating or blame coating, it is to be based on nitrogen to change silicon or the matrix of alumina. Nitrogen changes silicon the cutting tool of pottery and porcelain of mother radical has good tenacity commonly, apply to malleable iron, nodular cast iron and other difficult treatment quite cast-iron rough machining of the car with tall hardness alloy, mill. The cutting tool of pottery and porcelain that turns silicon to be mother radical with nitrogen besides suit to machine very much cast-iron besides, still suit to machine hardness the steel under HRC65 material, applicable is in turning roller and because rate is too low and cannot use brilliant to must increase model in the treatment of high temperature alloy of pottery and porcelain. When cast-iron car, mill is machined, the exterior linear velocity of 1524m/min can get most cutting tool life of economy. The pottery and porcelain that is mother radical with alumina has very good wear-resisting caustic sex, hardness moderate, be most material of cutting tool of pottery and porcelain, but should avoid to apply at the intermittent, treatment that touchs an article to copy net of Yu Huaxia pottery and porcelain to bump into material of tall perhaps hardness. Alumina base pottery and porcelain is multi-purpose the semifinishing machining at casting pig and finish machining. The tall compression intensity with this kind of qualitative material makes its special apply to bore hole cast-ironly treatment. But the pottery and porcelain that is mother radical with alumina fights thermal shock function to be differred quite, do not suit to use cooling fluid in treatment consequently. Contain carborundum new-styly (SiC) monocrystal or the buildup that brilliant needs Mu Jitao porcelain has alumina high melting point, high strenth and very good chemical stability, fight abrasiveness and heatproof concussion sex.

Brilliant needs those who improved data of pottery and porcelain to fight rupture intensity. Brilliant must increase model month of pottery and porcelain piece appear in that way like razor blade of traditional hard alloy rarely annihilative instantaneous burst or destroy, normally brilliant must increase model razor blade of pottery and porcelain is met only with a kind of attaint mode that can foreknow by wear away gradually. Brilliant must increase model the intensity of pottery and porcelain is higher than material of other pottery and porcelain, and special agree with alloy of treatment high temperature and similar material, if the spray of cast-iron, plasma of sclerotic steel, tall hardness is reached,solder the treatment of surface layer. If use brilliant to must increase model pottery and porcelain machines tall nickel alloy, interfacial temperature can achieve 982 ℃ , material purify rate can achieve the 10 times above of hard alloy cutting tool. Brilliant must increase model the high strenth of pottery and porcelain makes its special apply to intermittent treatment of car, mill and die / the treatment of the mould. Because have good heatproof concussion sex, brilliant must increase model cutting tool of pottery and porcelain can be used at working to cut, wet cut or intermittent and cooling and need not fear collapse knife perhaps produces hot tearing. The any crystalline substance that takes coat must increase model pottery and porcelain fits those need very much longer of cutting tool life, successive half essence and finish machining and similar be spent gently and moderate strength treatment. 3 times of the cutting tool of pottery and porcelain of life dispute coating of the cutting tool of pottery and porcelain that takes coat, but the treatment that does not apply to abominable condition to fall, if milling reachs interrupted cutting. The treatment of titanium metal does not recommend cutting tool of use pottery and porcelain, the burning point of titanium is very low, and inevitable meeting produces high temperature in treatment of cutting tool of pottery and porcelain, cause fire very easily so. The tigidity of the tigidity of arbor and machine tool is coequal and important. Below the environment of high yield, razor blade of pottery and porcelain must be installed to be placed on the special arbor that can avoid bit to produce little shift. Be in dangerous in extending longer turning, the tigidity of arbor appears particularly important. Hang greatly extend the deflexion that makes arbor generation more easily in high speed cutting tiny, and deflexion can bring about vibration and destroy cutting tool of pottery and porcelain. What use arbor because of razor blade of this pottery and porcelain is dangerous extend length to should shorten as far as possible, because the force of the generation when arbor deflexion can be followed,hang extended length to grow into cubic multiple, that is to say if other condition is changeless, of arbor dangerous extend increase 1 times, the deflexion of arbor can increase 8 times previously. Bore hole arbor is compared normally outside lever of round lathe tool has older long way to compare, because this uses heavy metal and arbor of hard alloy boring,be reasonable. As a whole, the steeliness boring cutter that machines nickel radical alloy to be able to use 3 times long way compare or the heavy metal boring cutter that 5 times long way compares (be like arbor of heavy metal vibration isolation) and the hard alloy boring cutter that 7 times long way compares.
