·Why to want to use cutting tool of helix of integral hard alloy: Because the uniqueness of cutting tool of integral hard alloy is qualitative. The quality cutting a margin of cutting tool of helix of integral hard alloy is all practicable in designing cutting tool best, in addition, cutting tool of paring of integral hard alloy is in of all sorts of paring machines most high speed falls to all can produce the admirable result that cut a margin into makings rate. · straight knife: Do not have the edge design of helix for straight blade, because the edge when cutting and the interface that machine content are big, obstruction arises and can bigger attrition makes edge wears away easily. Photograph of its service life is shorter to Yu Luo knife coming back, apply to the material with softer cutting to pledge. · helix knife: The design of its helix edge can reduce the content is contacted and arises with treatment resistance when cutting, besides can do high speed cutting, can improve treatment efficiency more. Opposite at straight knife, straighter knife grows its service life, suit the material with better cutting to pledge. Knife of · top spin: Alleged " top spin knife " those who point to is " right " cut coming back is united in wedlock " right " helix groove. Top spin knife can make wood chip is when cutting, helix ground up eduction, this is particularly useful below mill channel or the state that discharge bits not easily. Top spin knife falls in certain state, the meeting when cutting has the state that will have on treatment content. Need secures plant additionally or may need grading to finish cutting deepness. When top spin knife does the cutting of penetrable type, the cutting effect that machining content bottom can be meticulous and flowing. And in cut certain and specific material pledges when, the coping that machining content easily appears coarse Mao Bian. Top spin knife can be done direct and perpendicular the movement of the feed that be down or bore, but perpendicular feed appears easily the phenomenon of collapse blade, relatively do not suggest to use. We suggest to collect diagonal contrail feed, means of diagonal contrail feed is to increase axial to cut late movement to cut deep cost to the axial of set gradually, milling power is increased gradually, because this is right,the concussion of cutting tool and main shaft is compared perpendicular next knives are small, can reduce the phenomenon of blade of collapse leaving a sword apparently. · underspin knife: " underspin knife " point to " right " cut coming back is united in wedlock " left " helix groove, it is wood chip by eduction of treatment content bottom. What the cutting means of underspin can help treatment content at the same time in cut is fixed. Its cutting result and top spin knife are contrary, coping is meticulous and flowing, bottom has coarse wool state edge. Discharge bits to be able to create the problem of block occasionally downward, concealmenting especially below the state of type mill chamfer. Underspin knife is being used on apt finishs those who machine content to cut into parts beforehand cut, this action but considerably the stability when promotional underspin knife undertakes the edge is machined repairing. Underspin knife is unweller use at perpendicular the means that is down feed, this action is easy the problem that creates knife or block bit. · answer and type helix knife: Answer with type helix knife was to combine top spin edge and underspin edge to go up at same cutting tool. On, next blade cutting is compressible at the same time the coping that machines content to machine content in order to avoid or bottom have drossy or Mao Bian's generation. Answer be in by wide application with type helix cutting tool cutting is double-faced the layer pressing plate that sticks a skin (Laminate) , but on the natural timber that also can be used at issue of meeting hairiness side. · carries mill: Its edge is flowing design, cutting eventuate is meticulous and flowing, applicably at all sorts of requirement surfaces meticulous spent treatment. · thick mill: Its edge is undee design, the meeting when treatment has microgroove to arise, cutting result relatively upright milling cutter is coarse, multi-purpose at emphasizing meticulous spent treatment works, general meeting has the action of treatment 2 times. Thick milling cutter is not applied to low into makings rate. Mill of · degree of finish: Its edge is dentate design, intention is in the wood chip that will produce when cutting, cut off for smaller fragment, the energy when this action can reduce cutting expends those who reach cutting tool to swing, at the same time more the eduction of bits of benefit Yu Mu. Below the condition that swings without deflection in cutting tool, can complete thick mill and meticulous treatment action. Suggest in Gao Jin makings rate falls commonly, want cutting hardwood or this cutting tool is used when the talent with high density is qualitative. It is to upright to reach the good and eclectic tool between thick milling cutter at carrying milling cutter. Meticulous degree: Thick mill of ＞ of mill of degree of finish of Duan Xi ＞ breaks bits result: Duan Xi of ＞ of thick mill of ＞ of mill of degree of finish machines means sketch map:The treatment means of high speed cutting has a lot of characteristics, in principle is collected statified annulus cuts treatment, life of cutting tool of the treatment that arrange mill is longer, and go back and forth between lowest of life of mill means cutting tool back and forth. Direct and perpendicular be down feed to appear more easily collapse blade phenomenon, more unfavorable use. Means of diagonal contrail feed is to increase an axis to resemble cutting late movement to cut deep cost to the axial of set gradually, milling power is increased gradually, because this is right,the concussion of cutting tool and main shaft is compared perpendicular next knives are small, can reduce the phenomenon of blade of collapse leaving a sword apparently. Feed of screw type contrail is from workpiece upper part begins, helix is cut downward. Because use the means of successive treatment to be able to assure more easily to machine precision, and because do not have speed mutation, can use higher rate to undertake machining. Helix feed suits irregular appearance to reach most model antrum (the need that 3D) high speed machines. Brim feed is a kind of feed means of two paragraphs of type, treatment content is not contacted when small knife is down, next with transverse means feed, in order to avoid the happening of perpendicular feed. On machine of additional explicit CNC, the computer program of brim feed compares program of diagonal contrail feed relatively to be written easily.About receiving makings rate (Feed Rate) the information that provides under · expects for doing a choice to enter the reference of rate is used only, enter makings quantity and speed actually to get relevant factor affect and change somewhat. Content of tight ness rating of precision of the condition that relevant element bag contains machine precision, horsepower, clip to run a system, main shaft, spare parts, treatment secures state etc element to wait a moment. Generally speaking, cutting tool of helix of integral hard alloy enters makings rate to fall in high-speed, its effect relatively beautiful, for example: Longer service life, inferior damage is led. We suggest to choose first initiative begin into makings rate, increase into makings rate to appear till cutting result next undesirable or other limitation element is changed apparently. Metric changeover (Metricconversion): ? is branny kind of that chant?9.374 of of draw water ill will , can get minutely into makings meter (exemple: Minutely enter makings 300 flower , get after conversion minutely into makings 7.62 meters? ? 300/39.374 ＝ 7.62) the choice of slewing speed (RPMSelection): ? PM of Mo of astounded of word of of abundant of of of Qiong of ぬ of commonplace of collect of teach of uncut jade of Ba of of the full that review case is interpose at minutely 10000 to 20000 rotate. Jump over high slewing speed normally, the meticulous effect of its surface has healed. Jump over high rotate speed to will produce greater attrition power between cutting tool and treatment content however, this attrition force is to cause edge tatty advocate because of. Your target is to choose to answer rotate speed at all sorts of lowest that use a situation applicably. Relevant and formulary: Receive makings rate: Feed Rate slewing speed: RPM, point to main shaft revolution. Blade number: Feed of T every blade: Chip Load, it is to point to every time when cutting, single the crucial point cuts the material ply below from treatment content. This is a very useful when the set with new calculation is worth information. ÷ of Chip LoadRPM= Feed Rate of × of T of × of Feed Rate = RPM (÷ of Chip Load)Chip Load = Feed Rate of T × (T)ex of RPM × : Flower of Chip Load = 500(/ minute) / (blade of 15000RPM * 2) = 0.017 "
