Change silicon pottery and porcelain besides the nitrogen of traditional type beyond, in polymerization of nitrogen of A/b silicon aluminous oxygen material domain has the progress that a lot of your people expect. The high temperature character of stuff of this one type and toughness character can get be optimizinged significantly. Material of cutting of pottery and porcelain is a kind of efficient material, always use at high speed cutting (HSC) and efficient cutting (HPC) . As a result of cutting speed and feed speed rise, not only the cutting amount that increased unit time apparently, reduced sheet significantly treatment is right, also raised cutting to machine the economy of the process at the same time. Except this beyond the potential higher yield inside every unit time also reduced necessary machinery the investment expenses of craft. Regard cutting as material, polymer of nitrogen of silicon aluminous oxygen surpasses nitrogen to change nitrogen of silicon pottery and porcelain to change bricky pottery and porcelain to use the data that regards cast-iron workpiece as efficient cutting all the time. In cutting speed very high case falls, nitrogen changes silicon pottery and porcelain to be able to provide crackajack process security and process stability, and the high yield that assured equipment by right of wonderful economy is measured and very tall can control a gender. The development of material of cutting of polymerization of nitrogen of aluminous oxygen of the closest silicon enriched nitrogen to change silicon familial. Nitrogen changes silicon pottery and porcelain (Si3N4) is material of a kind of 2 photographs, the lever that its stabilize highly nitrogen changes silicon grain to store up in high temperature resistant crystal boundary (the 2nd photograph) in. The composition of material decided the hardness of cutting material, toughness and high temperature resistant quality. Through agglomeration the law can affect the structure of material, for instance nitrogen spends the L/D proportion of silicon grain, optimize with respect to what can undertake having specific aim to material photograph so. Change silicon pottery and porcelain besides the nitrogen of these traditional types, the B nitrogen that says namely changes silicon pottery and porcelain, in A/b silicon aluminium material gets oxygen nitrogen polymerization to still have activity of a lot of research and development inside the country. The character of material besides by the structure composition is decided, by material composition decides at all. In data of group of nitrogen of A/b silicon aluminous oxygen, the 2nd photograph has in embedding nitrogen changes silicon crystal lattice partly. Because this character makes,farther possibility affects a structure. Normally the material of this type is the high temperature that reforms in order to have is characteristic and famous. The material of this one sort can make the direction of the tenacity of characteristic field day of cutting material is optimized, considered taller wearability again on the other hand. Because disperse well fill grain of carbide horniness material, it is especially between grain of data of group of nitrogen of silicon aluminous oxygen, make nitrogen of silicon aluminous oxygen aggregate the hardness of cutting material and temperature mutation stability promote more likely. In addition the B nitrogen that is the same as traditional type changes silicon photograph to compare, aggregate material has nitrogen of silicon aluminous oxygen to fight oxidisability and chemical stability outstandingly. Graph the 1 A/b silicon that those who reveal is a model is aluminous the structure of material of cutting of oxygen nitrogen polymerization. Material of cutting of polymerization of nitrogen of silicon aluminous oxygen is used not only at turning, applicable also Gan Xi cuts the characteristic that as a result of its place its have. The use spectrum of data of new-style group of nitrogen of A/b silicon aluminous oxygen is very broad. Differ according to its the character of the type, enclothed arrive from rough machining finish machining, make light to strong interrupted cutting from level off. Because this silicon is aluminous,material of cutting of oxygen nitrogen polymerization is used not only at turning, use Yu Xi to cut as much. Black lead of cutting lozenge shape (GJL) and bulbiform black lead (the cast-iron workpiece of GJS) , treatment rate is rapid, volume of unit time cutting is high. When processing flake graphite work. Nitrogen changes silicon pottery and porcelain to be applied all bandwidth at using spectrum, and will wash this kind of material to workpiece of bulbiform black lead besides cut with Yu Xi, so far more the turning in applying to interrupted cutting and strong interrupted cutting. In cutting respect, what use above all is the A/b silicon aluminium that toughness course optimizes material of cutting of oxygen nitrogen polymerization, it is in material of cutting flake graphite was to show very tall productivity. SL808 cutting material is the achievement of direction of this one research and development. Using plane - ° of MKS90 of orthogonal milling cutter is flake graphite to material when the case of 250 undertakes thick mill is machined, as a result of the high temperature stability that SL808 cutting material promoted, make cutting speed achieved VC=1, 2OOm/mim. Every tine feed is Fz=0.

275mm, feed speed Vf=1000mm/min, width of clench the teeth comes for 5mm 12mm, cutting speed achieves maximum Ap=12mm. Although cutting cost is so high, every time the standard distance that cutting can achieve 50m. The expression in the comparison that the advantage of aggregate material can pass nitrogen of A/b silicon aluminous oxygen to change silicon with traditional B nitrogen comes out, for flake graphite to material for instance the compressor of 250 overspreads the surface to undertake cutting (graph 2) . The quiet with silicon identical pottery and porcelain is changed with B nitrogen in every tine feed besides below, SL808 of material of cutting of polymerization of nitrogen of aluminous oxygen of use A/b silicon, because of its higher cutting rate, make each part handling time corresponding shortened. In addition, its taller wearability makes the service life of cutting tool longer, this improved the economy of treatment again. In the case that shows. Through using group of nitrogen of A/b silicon aluminous oxygen cutting material makes cutting rate rose about 15 percent, cutting tool service life increased 63 percent. Every tine feed is Fz=0.

20mm, cutting deepness Ap=5.

When 0mm, cutting speed is VC=900m/min. Change photograph of silicon pottery and porcelain to compare with traditional B nitrogen, SL808 of pottery and porcelain of polymerization of nitrogen of A/b silicon aluminous oxygen is opposite the efficiency that flange face and face of snail clench solid had it also proves in thick mill treatment. Because the thermal stability of its height makes cutting speed OK,raise 800m/min from 500m/min. Feed speed from about 300Om ／ Min rises to be close to 4000mm/min, because this handling time decreased at least 20% . Although cutting speed and feed rate are higher, but the service life of the cutting tool of material of pottery and porcelain of polymerization of nitrogen of aluminous oxygen of use A/b silicon is use B nitrogen changes 2 times of cutting tool of material of silicon pottery and porcelain. Service life rises significantly, and at the same time handling time shortened again, this makes treatment charge decreased at least 30% . In the comparison that undertakes in different use position in the hard alloy that is the same as alumina coating, pottery and porcelain of polymerization of nitrogen of A/b silicon aluminous oxygen also underwent test. Cutting the profile of snick form case, cutting deepness Ap=3mm, when Ae=40mm of width of clench the teeth, used a diameter to be 50mm, the milling cutter that contains blade of cutting of 5 MSK88 ° replaces the bigger horniness that contains 7 cutting a tooth-like part of anything to add up to more than milling cutter to cut off join face. Because its are admirable high temperature resistant the gender makes cutting speed achieves VC=100m/min, feed speed Vf=3600m/min, receive 3 what be bordering on initiative value.

6 times. Because used pottery and porcelain of polymerization of nitrogen of A/b silicon aluminous oxygen to shorten,machine cycle, improved the cutting tool service life of every workpiece, milling cutter replaced 7 cutting tine with 5 cutting tine only, and razor blade of every dislocation type has 8 is not 2 cutting blade, because this uses hard alloy to undertake machining be comparinged together, the economy of treatment rises significantly. Consider the installation charge that the apportion in year production goes to merely, reduced 70% . Manufacturing GJS400 bearing the ° of MKS90 of planar and orthogonal milling cutter that used a diameter to be 80mm (graph 4) . To different diameter when first time clamp circular mill is cut, ae=40mm of width of clench the teeth, cutting deepness Ap=10mm. The hard alloy photograph that uses alumina coating together is compared, feed rate rose 3000mm/min by 550mm/min, make handling time from 6.

8 minutes decreased 1.

25 minutes. Service life is long, the development of material of pottery and porcelain of polymerization of nitrogen of aluminous oxygen of silicon of economy tall A/b, can be being regarded is nitrogen changes silicon pottery and porcelain the direct way of familial development. Change silicon pottery and porcelain with traditional B nitrogen of pottery and porcelain of polymerization of nitrogen of aluminous oxygen of silicon of photograph comparing, A/b high temperature resistant gender and wear-resisting caustic sex rise significantly, and its tenacity in use spectrum was not restricted. Group of nitrogen of A/b silicon aluminous oxygen is used below the case with cutting high condition cast-iron material proved cutting of SL808 of pottery and porcelain this. Compare with phase of data of hard alloy cutting, the advantage show that leaves its taller wearability in high temperature circumstance is in of cutting speed and feed speed rise: And with B nitrogen photograph of the pottery and porcelain that change silicon is compared, it is OK aborning achieves longer service life and taller economy.
