How does corrugated fibreboard product line choose cent to cut Bao Dao and emery wheel

Paper box factory cuts Bao Dao to reach in cent of choose and buy when grinding a knife to use emery wheel, because produce manufacturer and agency to stem from the purpose with conservative technology, won't make its bases and construction detailed introduction commonly. Reach to facilitate cent of choose and buy of paper box manufacturer cuts Bao Dao grind a knife to use emery wheel, the author shares his trifling experience and everybody here. Broad corrugated fibreboard (box) manufacturer can know a few basic common sense and its character from which, then can cent of more reasonable choose and buy cuts Bao Dao and emery wheel. Current, our country numerous cent cuts Bao Daosheng to produce manufacturer in, the cent of average production cuts Bao Dao is two kinds big to be as follows: It is tool steel kind; 2 it is hard alloy kind. Tool steel kind steel of minute of tool of the high speed that it is · (common weighs high speed steel) W6Mn5Cr4V2---Tungsten 6 manganese 5 chromium chromium steel of · of 4 vanadium 2 (common calls a mould steel) Cr12---Steel of tool of alloy of · of chromic 12 (common calls a tool steel) 9SiCr---9 silicon chromic above steel of a few kinds of tools kind after cent cuts Bao Dao to be handled via quenching, although Rockwell hardness does not differ,go to a few degrees, but because rolled steel is chemical elemental composition is different, raw material price reachs production cost to differ bigger. Although the price on the high side of knife of high speed steel, but there still are a lot of manufacturers to choose knife of high speed steel on the market, the high temperature resistant, tenacity that has because of its is good reach peculiar red rigid to wait for a characteristic, can make blade keeps sharp and abiding, relatively other tool steel kind Bao Dao performance characteristics is advantageous, hard alloy kind (common calls wolfram steel the knife) cent is · tungsten cobalt kind · tungsten cobaltic titanium kind the razor blade that normally our country produces is tungsten cobalt kind (YG) , the raw material of this kind of razor blade and make this bigger, hardness good, service life grows tall, wearability, but do not have tenacity as a result of its, bending strength bottom, the price is high. Cut Bao Dao in the light of use component, use the grinding emery wheel that suits to it, can assure a knife service life. Abrasive tool steel kind Bao Dao's emery wheel its are main raw material is " cubic nitrogen changes boron " (CBN) , call cubic nitrogen to turn boracic emery wheel. Grinding hard alloy kind Bao Dao's emery wheel its are main raw material is " corundum " , call diamond emery wheel. Above two kinds of emery wheel, the material that is not professional personage to use naked eye resolution very hard to give it from the exterior is qualitative. What pledge as a result of material is different, utility has very big distinction, cannot replace each other. To facilitate the person that use judges the sort of emery wheel directly from the exterior, the emery wheel that pledges different capable person commonly, mark with different color. The color of emery wheel just assists material one kind, do not affect the grinding result of emery wheel. The emery wheel substantially that at present our country produces namely green, iron oxide red is lubricious, black 3 kinds of color. The emery wheel color of the different production that uses raw material, recipe and technology as a result of the emery wheel place that each manufacturer produces has certain difference, but use effect agrees basically. Thin knife of common tool steel uses green with emery wheel, hard alloy thin knife is color of iron oxide red with emery wheel, black emery wheel wants look to appoint. Such clients pledge with respect to the material of OK and intuitionistic resolution emery wheel and utility. The degree of finish of emery wheel, basically decide by the granuality of abrasive. Does commonly used cent cut Bao Dao to grind a knife to basically have 120 with the granuality of emery wheel abrasive? 40 eye, 140? 70 eye, 170? 00 eye. Size number is smaller emery wheel is thicker, the emery wheel grinding that although produce,goes out is quick, but the blade point that grinding gives is bright and clean degree low, coarse, corrugated fibreboard separates side of the hairiness when cutting. Size number is larger emery wheel is finer, although grinding speed is formerer a bit slow, but the blade point that grinding gives is bright and clean degree tall, blade peak level off is smooth, the corrugated fibreboard margin that cent cuts is orderly, without Mao Bian. What the emery wheel that general manufacturer produces uses is the abrasive of same size number, the abrasive adulteration of the number of will distinct size that also has a few manufacturer is used. Above just was at 2 o'clock on size number relative to character. Among them grinding character and service life and product recipe, craft is having very big concern. The chroma of emery wheel is how many what point to emery wheel sand content, the emery wheel concentration that normally each factory produces is more 75% . Because arenaceous degree of finish and distributinging circumstance difference are very big, the user is very difficult make judgement to the sand content of emery wheel from the exterior. A lot of more current the chipboard product line of paper box manufacturer, cent cuts the bearing that the knife grinds to use emery wheel on machine to be chosen more " F " kind bearing. On home market, this kind of major produces manufacturer not only with bearing less and the price is too high, it is more difficult to be purchased by oneself. If introduce the product with low price, quality produces a demand with respect to short of. Good too expensive, cheap too poor, what had used no matter is worn-out, cost raises greatly. To reduce cost, do not affect the grinding quality of emery wheel at the same time. The author passes old experience to accumulate, the proposal tries to improve the axis on emery wheel bracket, make the emery wheel that uses formerly at the same time a few alter, so that use a few home to use more general bearing, can assure bearing service life already so, go to the lavatory again purchase, big political integrity produces cost about. The author was in what manufacturer succeeds to improve axis of emery wheel bracket and emery wheel, the report after much home manufacturer is used is favorable. The emery wheel after improving uses 607ZZ bearing, increased firm sex, prolonged the service life of emery wheel, reduced purchase cost. CNC Milling
