Chinese early begins to produce architectural pottery product namely before, famous " Qin Zhuanhan is made of baked clay " the delegate that is them. "Green tile is abandoned " it is archaic architectural all the time essential element. The architectural pottery product that has contemporary sense is produced only then at going up century 80 time. To living environmental vision is gone after beautifully and the city changes people is the puissant engine that drives architectural pottery product to develop quickly. Through development of nearly 30 years, architectural pottery crop of China already held a whole world 50% , the product exports 200 countries and area. Crop of wall floor tile achieved 5.4 billion square metre 2009, be in world first position 6 years continuously. The problem that cut machines is faced in the architectural pottery product that gives priority to with wall floor tile is being produced and using a process. People is necessary to curium to cut of pottery and porcelain of characteristic of itself of architectural pottery product and agglomeration diamond the respect makes a property deep the understanding of one pace. One, the classification of pottery and porcelain people is customary at " contented " and " porcelain " join call together. Actually, although both is the same as what make for raw material to wait with clay, feldspathic, quartz " earth " goods, but because make the difference of technology and craft, contented and porcelain are put in the differring with obvious move. The civilization in the mankind history in, ceramic appears to already had 2 at least, 30000 the history, antedate far china. BC controlled Iranian area to have ceramics 4000. And be in archaic China, yangshao culture period (BC 5000 to BC 3000) ceramics has developed highly. Crockery is called again " crockery " , its section is coarse, a lot of more stomatic, bibulous rate is high (﹥ 6% ) , hardness is not tall. China is with porcelain clay (kaolin) give priority to fire and become, outside layer part often besmears with glair layer, its section Jun is close, exquisite, exterior luster, bibulous rate is extremely low (﹤ 6% ) , quality of a material is solid, sound is ringing and euphonic. Since ancient times folk has " without diamond, do not pull china to live " view, make clear what already had to china is ancient " difficult treatment material " . Still the argillaceous goods between both of Yu Tao of a kind of interpose, porcelain is called " Shi implement " , say again " crock implement " , less humanness place knows. All previous arrives via developing several years now, pottery and porcelain is familial already very giant. A general designation of new-style and careful pottery and porcelain that contemporary material taxology rises traditional pottery and porcelain and modern development is " narrow sense pottery and porcelain " . And " broad sense pottery and porcelain " included content is more wide extensive, the finished products that stuff of metal of body of inorganic ranginging from... to... , cement, glass, fireproof material and tile wait material of content of siliceous salt mine a moment to give priority to and material of narrow sense pottery and porcelain belong to this one category completely. Architectural pottery basically points to goods of brick, tiling, the exterior wall tile that as usual sees, floor tile, red tile, green cover with tiles, red brick, blue bricks, glazed tile, eaves tile, tile act the role ofing is waited a moment. 2, the characteristic of architectural pottery and the life relationship that machine the requirement architectural pottery of quality and people to cut are very close. "Looking up is wall brick, lower his head to see floor tile " , the architectural pottery colour that is main representing with wall floor tile is diversiform, configuration each different, quality of a material is different, dress up a contemporary mankind much appearance to live colorfully, working environment. Substantially of wall floor tile can divide for 3 kinds of types: 1, glazed pottery: The surface has glassy layer, surface layer hardness is taller, but hardness is not tall under surface layer, bibulous rate is high. 2, horniness exterior wall tile: Hardness is medium, bibulous rate is not high. But fractionize is " opaque " and " quartz is qualitative " 2 kinds, latter density, hardness all is more than former, and bibulous rate under former. 3, Bo changes a brick (call quartz the brick again) hardness is highest, bibulous rate is low. In make and decorating a process, to assure the requirement of geometrical dimension, often need to have cut to goods of wall floor tile. The requirement that Nextpage 　 cut machines: The first, cut efficiency. The cut of wall floor tile is not exceptional also. Because what this uses a tool must sharp. The 2nd, because pottery and porcelain is hard fragile data, the exterior quality of wall floor tile with " figure project " relevant, to cut fracture surface namely " collapse edge " (also say " explode edge " ) quality requirement nature is very tall. The 3rd, the service life that there can be moderate below the premise that need cut tool is satisfying two afore-mentioned requirements. Of course, so " DIY " (DO IT YOURSELF) kind the product need not make exorbitant demand. The cut gross that decorates because of the individual cannot be too big, reason is right curium a life requirement is not sensitive. 3, cut of agglomeration diamond pottery and porcelain curiums a problem of partial general character in designing production. Although architectural pottery hardness is taller (especially Bo changes a brick) but with the hardness of diamond photograph comparing is remained " be outshone " . Coping with pottery and porcelain with diamond cut tool is again natural the alternative that does not pass. But the problem is not the hardness between two kinds of material " wrestle " simple in that way. "Make a thorough break " not difficult, wanting cut hard already sharp, want to make sure edge of cut level off, collapse is slight again. Well-known, agglomeration diamond cut curiums piece structural cent is 3 parts, namely: 1, working section (say again " knife head " , " tine " , " section piece " ) form by diamond crystal and metallic bond. 2, the blame diamond that uses for soldering layer part (also have need not this) . 3, matrix is like 50Mn, 50Mn2v, T12, T10 to wait by 65Mn or other steel products make. End panel is jumpy to stiffness, flatness, tensile stress, parallelism, radial, jumpy have firm demand. From rupture the angle of mechanical theory looks, architectural pottery destroys tenacity low, its cut those who cut fracture surface to form is the result that the brittleness that local surface produces the material of pottery and porcelain that the diamond grain in motion causes ceaselessly ruptures. Use thick grain high temperature to spend diamond to conduce to material of architectural pottery of high speed purify, raise cut to curium thereby piece sharp degree, but of surface of pottery and porcelain rupture degree aggravate can affect port surface quality (namely " collapse edge " the effect) . Because of this, agglomeration curium piece distributing to diamond grain the kind that takes multilayer and distinct size accords with logic. The two side of working layer and curium the high share such as a backlash uses 60 ／ 80, 120 diamond of 100 ／ , working layer is mid (exceed knife head total volume 50% ) use 50 ／ the thick diamond of 60. Can obtain so " sharp and explode the edge is slight also " cut effect. The bond component that diamond job layer uses and its density curium to agglomeration piece working state also has very main effect. Hold is too strong, curium piece differ from acute sex, curium piece sharp degree of attenuation is fast; Conversely, sharp spend on the low side. Consider to make clear, use Fe, Cu, recipe of bond of Sn3 element tall brittleness, complementary with necessary additive, can resolve this one contradiction well. Diamond cut curiums piece widespread attention was not caused before agglomeration craft changes a problem to look subtly. It is sintering furnace of furnace of use box type, well type furnace, bell cover furnace, pressurization or successive sintering furnace no matter, the manufacturer is satisfied at following a tradition only mostly " bond advocate component melting point 60, 80% values " agglomeration craft, and oversight the influence that agglomeration organizes change to matrix metallographic. A large number of facts prove, impact of position of matrix metallographic organization curiums a cut effect, include among them sharp degree, wait from edge of acute sex, stability, collapse. Be worth manufacturer thoughtful, cannot " visit knife head only, disregard matrix " . According to the author's practice, cut of pottery and porcelain of relatively ideal agglomeration diamond curiums piece should have the following essential factor: 1, diamond: Thick, fine reasonable and statified platoon cloth; 2, metallic bond: The brittleness bond that low alloy converts; 3, matrix: Thin model, narrow seam, stiffness is good, use the agglomeration technology that can acquire reasonable metallographic to organize state. Of course, if can configure high speed, bridge-type (or door type) cut machine, curium piece cut effect will be more outstanding. This needs with curium manufacturer cooperates a cut equipment closely, fang Nengda arrives " good horse matchs good saddle " macroscopical effect. Write here, the author wants to allude incidentally cut of material of diamond pottery and porcelain curiums piece replace a kind, namely " electroform, drill rod solder, combination " type curiums piece, its specific power consumption that make is low, take up the space is little, installation cost is not big, matrix can be used repeatedly, with norms sheet synthesis of manufacturing put together curiums under agglomeration cut far originally piece, and sharp effect of degree of the side that reach collapse is very good, performance is steady, what need cut power to also curium under cut of pottery and porcelain of traditional agglomeration diamond piece, have very good development perspective.
