Razor blade of newest PVD compound film machines the program that offers tall productivity for the profile modeling milling of aviation and mould domain. Applied PVD (deposit of physical gas phase) the new-style and compound film of film technology is in in the light of material of tall hardness workpiece high-powered the mill razor blade that establishs mill and profile modeling mill is acting an important role in development. The high speed finish machining of the high temperature alloy that the applied domain of rapid growth includes to be used at current reaction engine to make and mould. In the light of more the bit with the better tenacity of high strenth alloy is in aviation industry, pursuit lights effect taller as quieter as the reaction engine demand drives high temperature alloy to develop to what increase the respect such as purity, tenacity and high temperature intensity. But, these progress have negative effect to processability. As the addition of intensity of alloy high temperature, the power that produces action to go up in cutting blade when establishing mill and treatment of profile modeling mill. Its are as a result, once applied to the material of C-2 hard alloy that processes alloy of alloy of a lot of kinds of titanium and nickel radical high temperature to pledge grade becomes no longer appropriate. If apply the high temperature alloy now, they destroy what suffer cutting blade inevitably as serious as place of cutting deepness line groove to wear away. One of achievement to this kind of research and development were to had rolled out qualitative order and degree of advanced material of milling of fine grained hard alloy, it is had in application of high temperature alloy increase cutting tool life and the capacity that improve dependability. Compare with traditional hard alloy photograph, fine grained hard alloy is had taller fight reduce intensity, it is for tenacity merely its cost is a few higher. Accordingly, they resist high temperature alloy machines common failure mode to want to be gotten effectively than traditional hard alloy much. To improve the productivity that high temperature alloy machines, PVD film to raise the wearability of cutting blade and tenacity and do not sacrifice of matrix of fine grained hard alloy fight compress intensity and hardness and of research and development. The ground floor of this kind of film is nitrogen changes titanium (TiN) , below one is carbolic nitrogen changes titanium (TiCN) , it is azotic aluminium changes titanium next (TiAlN) . Look from the history, the versatility of TiN film is best, the cutting operating mode to very wide range and alloy of a lot of kinds of titanium alloy, high temperature are effective. TiCN is harder than TiN, and have afore-mentioned advantages. The 3rd kind of film has appeal most in a few the closest years. When it is rolled out for the first time, as a result of film surface coarser and consistency is not quite good, increase the capacity of cutting speed in finite applied circumstance only. What brought about speed ability and hardness in the content that aluminium raises in turning application is dramatic rise. Then the applied limits of this kind of film expanded. The material of milling of fine grained hard alloy nowadays pledges grade was combined multilayer such film, the performance that and be confirmed compares forms of any inchoate and single film in very wide application range is better. Ability of newest PVD compound film pledges grade still offers other and significant advantage. Among them one of it is dry cutting. Because these material pledge grade is below rapidder cutting rate,excise very small cut bits, do not need cooling fluid to control the tumour accumulating bits on cutting blade or workpiece normally. Accordingly, can eliminate the negative environment influence related to use cooling fluid and cost expense normally. Two kinds of when be a pioneer high with hill new technologies offer socioeconomic advantage in this domain. We can be offerred now win the very complex milling slot that can produce by grinding only in the past through direct suppress or extruding means model. Eliminate this kind of costly process to mean the program with a kind of lower cost that processes difficult treatment data. The domain of another fundamental application of hard alloy of fine grained of the chamfer that is aimed at mould application as compound as film PVD film is mould industry, they can provide the capability of finish machining of high speed of steel of strong tool of temper by dipping in water. Below a lot of circumstances, the treatment surface surface roughness that treatment of these milling of high speed profile modeling can obtain is good the manual polish that be reduced dramaticly to enough or cancels benchwork even or method of other handiwork finish machining. Total handling time can decrease amount to 25% to 30% . Tall to hill for, it all profile modeling milling cutter that are aimed at mould application use bit of hard alloy of fine grained of PVD compound film, these razor blade are comprised by the cutting blade of the classics nicety grinding that has blade of two effective cutting. The cutting blade that a of PVD compound film remarkable character is them is very sharp, a kind of development of the point of view that it represented a tradition to think the Gao Jin of hard data needs particularly strong cutting blade to treatment. The hill that is used at mould treatment is tall hard alloy of newest fine grained of PVD compound film is qualitative grade of the F15M that establishs mill system research and development for famous little tyrant small diameter and F30M milling material. A of the very sharp cutting blade about these razor blade important complement is PVD (deposit of physical gas phase) film technology. Because PVD film is thin, although,they duplicate accurately it is very sharp cutting blade. Then its end item gets the wearability of cutting blade and chemical stability couple together the chamfer with very light cutting. And reduce as a result of what PVD film won't cause point strength, the tenacity of cutting blade is good, because this can be counteractive,die blade. The product is commented the combination because of the character with light cutting and high cutting blade intensity, use at little tyrant to establish the talent of milling of PVD compound film with mill system high hill to pledge grade is when aviation and mould material treatment provide efficient and reliable performance. F15M material pledges special design uses grade at milling of high speed profile modeling to machine the superfinishing in, and the application that F30M material pledges grade design is used at finishing wider range. It will be steel, the finish machining establishing mill of stainless steel and high temperature alloy and semifinishing machining provide reliable performance, and the hard steel of temper by dipping in water that enough processes hardness to be as high as HRC 55. The chamfer of B90 razor blade with sharp blade of cutting of combinative little tyrant, f30M material pledges grade can be used at the rough machining of mould or aviation material and semifinishing machining. To finish machining of profile modeling milling, this material qualitative grade and chamfer of accurate ball head B90P combines, it also has sharp cutting blade and in cutting thin when cutting bits especially effective. An Edge On PCBN As An Alternative Approach To Meeting The Requirements Of High-hardness Endmilling And Copymilling Operations, some Cutting-tool Manufacturers Have Developed Either Negative, or Dead-flat, insert Geometries Aimed At Providing Greater Edge Strength. To Obtain The Necessary Cutting Speeds, PCBN-tipped (polycrystalline Cubic Boron Nitride) Inserts Are Used, which, in Effect, remove The Hardened Work Material By Rubbing Or Burnishing, rather Than Cutting.
Though This Machining Technique Creates Tremendous Heat In The Insert, the PCBN Cutting Material Is Able To Withstand It.
For This Reason, carboloy Also Offers PCBN-tipped Inserts As An Alternative To The PVD Multi-layer Micrograin Carbides.
From Our Perspective, however, the Real Value Of PCBN For High-speed Finishing Of Hardened Materials Lies In The Future, when We Can Expect Requirements For Still Higher Cutting Data.
In The Meantime, the PVD Multi-layers With Ultra-sharp Edges Offer Proven Capabilities To Meet Todays Requirements As Well As Or Better Than PCBN, and At Significantly Lower Cost.
