The PCBN of innovation sex gets together the electronic metallograph that nitrogen of brilliant cubic metre changes PureCut DHA650 of boracic cutting material, see the grain of accept rice class in binder from which. Micromechanism design is helpful also to crackle direction deflexion, also assist the stability that increased cutting material thereby (graph 2) . Further research is informed: The crackle that composite material forms accept rice is waviness rise and fall, having greater exterior flaw, this also increased the capacity with counteractive patulous crackle. This one character is having first-rate action and sense in interrupted cutting. When checking for example, the anti-impact properties of PureCut cutting material gets together than standard PCBN nitrogen of brilliant cubic metre changes boracic material to be close friends 50% the left and right sides. Graph 2.
PuerCut gets together the electronic metallograph that nitrogen of brilliant cubic metre turns boracic crackle area. Special crackle turns to the length that increased crackle, also improved the exterior composition of cutting material thereby. In auto industry domain, such improvement is meant than before lower cutting tool cost. Of stability of cutting cutting tool rise to also be helpful for handlers using treatment of bigger cutting of deepness of penetration of a cutting tool, also improved the cutting performance inside unit time thereby. When be heated (> 700 ℃ ) when surface of material of cutting of the glide that cut bits, PCBN gets together nitrogen of brilliant cubic metre changes boracic meeting to produce chemistry to corrode. This kind of chemistry is corroded understandable get together for PCBN nitrogen of brilliant cubic metre is changed mechanical wear is mixed between boron and workpiece diffuse to make used kill integratedly. After taking undermentioned step, of material of PureCut cutting tool fight chemistry to corroded function to have improvement: Because ● used what the grain binder of size of accept rice class makes agglomeration quality compares forecast thereby to have bigger improvement. ● and traditional PCBN get together nitrogen of brilliant cubic metre changes boron to differ, pureCut card gets together the foreign matter that nitrogen of brilliant cubic metre turns boron not to contain the remain in producing a course (the typical feature of rudimental impurity is to having get together unlike PCBN nitrogen changes brilliant cube boracic wear rate; After removing these impurity, can have longer, controlled wear rate -- refer to a graph 3) . ● reduced CBN cubic nitrogen to change boracic content; For example of PureCut DIA500 brand get together nitrogen of brilliant cubic metre turns boracic material. This increased capacity of tatty of shape of hole of crescent moon of face of the knife before cutting tool is counteractive. Graph 3.
The PureCut binder of tall purity (Zun Tu) with the tradition, the PCBN that contains impurity gets together nitrogen of brilliant cubic metre changes boron (right graph) metallograph. The service life that the micromechanism that tall purity binder forms can prolong cutting material, better resist chemical abrasion. As a result of very tall wearability, the cutting material of PureCut brand is having longer cutting tool durability below the cutting rate that raises significantly. For example, below the operating mode of cutting speed 220m/min, get together than the standard the cutting tool durability that nitrogen of brilliant cubic metre changes boron rose about 40% , and bear the performance of interrupted cutting is stronger. Should be in in cutting process when use cooling fluid, PCBN gets together nitrogen of brilliant cubic metre turns boracic cutting material fight temperature bear function, especially interrupted cutting process fights temperature bear function mediumly, still can assist the precision that improves cutting treatment; It is with auto industry domain exemple: Can assure very strict public errand. Because new cutting material is having very good heat conduction property. For example, CBN cubic nitrogen changes boracic content to change thermal conductivity of boracic cutting material to be between 18~38W/mK in the common and cubic nitrogen of 45%~55% . The brand gets together for the PureCut of DIA500 nitrogen of brilliant cubic metre changed boracic material thermal conductivity to achieve 50W/mK. And similar thermal conductivity has nitrogen of CBN cubic metre to change boracic content only the common and cubic nitrogen of 65% changes boracic material ability to get. As common as the past, thermal conductivity is in of 49~52W/mK get together nitrogen of brilliant cubic metre changes boracic material to differ, the cutting material of model of PureCut brand DHA650 benefits a lot from inside the agglomeration craft of its high quality -- the thermal conductivity that can achieve is 75W/mK. The heat conduction performance with superior implementation of tall agglomeration quality goes out for development can applicable all sorts of cutting data that use a case, element Six company is having the partner with a lot of very close connection in Europe, East Asia and America, collect condition of equipment of concerned machine tool, craft and local market for a long time to develop the information such as the trend to them, these information that arrive in order to collect regard important basis research and development as new product, in order to satisfy global market demand. Relevant partner also participated in lab test and large-scale spot experiment to wait for the job in process of research and development, give Element Six the company gotten test result feedback, form a complete iteration loop thereby. This kind of good interactive cooperation is one of recipe with PureCut cutting successful material, more lengthened cutting tool durability 20% ～ 30% . CNC Milling CNC Machining
