The 1 application in turning treatment is in turning steel when material is machined, to the treatment of hard steel of temper by dipping in water, exceed hard data cutting tool to be able to achieve the treatment result that grinds with car generation greatly. In cutting treatment process, as a result of its cutting deepness wants far outclass grinding, the work efficiency that grinds with car generation improved on great rate, reduced the cost that treatment makes thereby. Those who need an attention is, when undertaking the component machines tall hardness machinery, should take low speed or in the cutting means of low speed, prevent to exceed orbit of cut of deviate of hard data cutting tool. Nextpage is in turning is cast-iron when, to the exhaust valve base that engine crock builds, can choose alloy cast iron of Gao Ge of copper, molybdenum, the treatment of this kind of material has turning and milling commonly 2 kinds of craft. When the cutting tool that makes with PCBN stuff place machines undercarriage of casting pig Buddhist templeput on the brakes, its cutting speed is in commonly 700~2000m/min is optimum. 3.
When the aluminium alloy of cutting tool milling that the 2 application in milling treatment make with PCD material, when its speed can achieve the casting pig of cutting tool milling that 300~4000m/min; makes with PCBN, its speed is commonly inside 1000~2000m/min limits. Current, the speed of cutting of PCD face milling cutter that our country machines aluminium alloy crock to build already achieved 4021m/min, its feed speed is 5670mm/min, this kind of efficiency is 20 centuries of our country 2 times what 90 time initial stage introduces foreign device. The rate of milling of CBN face milling cutter of cylinder body of finish machining casting pig also achieved 2000m/min, its efficiency is milling cutter of hard alloy face of 10 times. In vitreous deep treatment, application of milling cutter of face of fluid of the platoon inside the PCD helix of milling glass is most wide. 3.
The 3 application in broaching treatment are in broaching treatment, use complex formula involute to jump commonly aperture of workpiece of treatment of broach of hard data of the Kong Chao inside tine, its advantage basically has at 2 o'clock: It is spline blade firstly the tooth structure that opens backlash and jump reasonably pattern of tine platoon cloth, assured the production quality of broach, and its workmanship is not complex, broach photograph compares cost and common complex formula involute to also do not have too much difference. It is means of this kind of treatment made sure the coaxial between each shape face spends the aperture inside workpiece secondly, in follow-up treatment working procedure, OK and unified choose trail round face to be fixed position fiducial, the foreword after making thereby examines of arbor and fixed position arbor make simplified a lot of, also made sure each machine positional precision of the surface at the same time. 3.
The 4 bore with a reamer that cut treatment to apply mediumly in hard cast alveolus or hard steel of temper by dipping in water in bore with a reamer cut treatment in, PCBN eletroplates reamer application is very wide. This kind of reamer serves as matrix with the 45# steel of 9CrSi or 42HRC, have cutting and around oriented part. Its matrix design wants very reasonable, and production precision demand is very high, oriented part is large before cutting part should be compared 0.
04mm, workpiece hole depth should be less than cutting area length, after cutting area length should be compared, direct length slightly small. For example, some factory machines what the diameter is 12mm about to quench steel workpiece, its hardness is 45HRC, bottom dimension is 12mm about, the cylinder that machines requirement aperture is spent for 0.
005mm, exterior surface roughness is 0.
2 μ M.
What this moment chooses commonly is a group 5 eletroplate CBN reamer will undertake machining. Some engine manufactory uses PCBN or PCD eletroplates the headstock aperture of body of cylinder of bore with a reamer of reamer top gem will replace honing, this kind of practice makes work efficiency rose multiple, and quality of treatment finished product is stable. 3.
The 5 phenomena that getting the application in cutting treatment to process project pottery and porcelain, glass and stone material with PCD broach are very common. Company of deep treatment of inn of a lot of glass and glass uses PCD broach to drill the hole that cuts glass and mirror. Current, our country's common diamond bit diameter is commonly between 3~130mm. Vitreous broach has colophony diamond, also have those who enchase diamond. With PCD broach treatment stone material and project pottery and porcelain have efficiency the good point with tall, good quality. Diamond electroanalysises auger cut usable will shape the columnar aperture on all sorts of difficult treatment conductor (blind Konghe via) , special model Kong Heyuan taper hole. Nextpage epilogue: Show level, the machining branch demand to machining is complex with each passing day and diverse, besides assure to machine quality besides, machining flatness, smooth degree and fight abrasiveness to be able to wait for a respect to also raise taller requirement, traditional metal or metallic alloy cutting tool cannot have satisfied the machining requirement with slashing condition. The use that exceeds hard data cutting tool can very good settlement problem of this one treatment, increase the unique dominant position that exceeds place of hard data itself to have, obtained on the machining work of different domain relatively the result that showing. Use to realize the dimensions that exceeds hard data cutting tool to change, promote machining quality and treatment efficiency, broad machining personnel needs to strengthen the study of oneself major skill ceaselessly, thorough knowledge and analysis exceed hard data cutting tool the problem in machining and inadequacy, so that be optimized accordingly and perfect countermeasure at adopting, the further progress that is machining provides fundamental safeguard.
