Implementation tall productivity is not accidental

Nowadays, machinist often is asked to carry out the job that cannot finish once upon a time. The client asks delivery time shortens, and the part is more and more complex however, and want reduce cost greatly, these created enormous pressure to workshop staff member, bottom line of cost of prep let alone. Want to win competition in current market, the company must have banner level, this are what secret no longer. But the problem is, how choose and use current and usable technology, in order to achieve competitive advantage. Each factories must undertake assessment to technical level, choose those to be able to satisfy a client already next need, and apply in production in the technology inside limits of plant personnel skill again. As decrescent of spare parts batch, the pressure that reduces manufacturing cycle becomes a factor that improves overall productivity increasingly nowadays. The assembly of the machine tool and the crucial part that disassembling is compositive delivery time. Most good cause is as soon as possible cutting metal, fast and handy implementation exercise changes. Givener than hoping to be in like a restaurant time paragraph inside make full use of client of oneself great majority of service of desk and chair is same, each factories must change operation quickly, be in condition of treatment spare parts in order to maintain a machine tool at any time. Main shaft of high speed milling is being used on Switzerland machine tool is a kind of newly emerging things no longer. But the basis uses an occasion and decide, choose proper accessory configuration to appear very important. A company that achieves this goal successfully is the three-dimensional treatment company that is located in coast of Florida city Riviera (3D Machining Corporation) . 3D has history of 5 years, offerring implementation for its machinist nowadays the cutting tool that highest productivity needs. Although others is in,reduce investment, the new Xi Tiecheng that 3D is having main shaft of high speed milling however invests on the machine tool, in order to satisfy the small treatment requirement of company hi-tech client. A key with successful 3D, it is the main shaft of high speed milling that chooses to suit a factory to need. The choice of main shaft of high speed milling undertakes on Switzerland machine tool high speed milling is not strange thing. Machine job shops is using air main shaft and dc main shaft all the time, through (size scope is 0.

004 ～ 0.

125 inches) broach and establish milling cutter to realize taller exterior precision. On small diameter milling cutter, to achieve the higher load that cut bits and exterior rate, must use higher rotate speed, in order to make full use of cutting tool. The eclectic method of technical respect is a lot of auxiliary main shaft must reach high rotate speed through sacrificial torsion, reduced what can use to cut so deep. Because working area is opposite more compact, the diameter of noumenon of auxiliary main shaft of provide for oneself must enough small, in order to suit Switzerland model or the need with lesser area of treatment of modular machine tool. Limits of usable rotate speed is 15, 000 ～ 60, 000 R/min, deliver torque through means of planetary gear drive. Compact structure limitted the size of dynamical drive, reduced the effective torque of efficient cutting and tigidity. Eddie Pena is the vice president that officer of three-dimensional treatment company makes, for its Xi Tiecheng machine tool chose accessory of high speed of mechanical drive type. These device and oriented sleeve cooperate closely, can reduce deviation thereby, make install and disassemble more convenient. The installation of air and dynamoelectric main shaft is compared likely also complex, need has the maintenance with knowledge of respect of code of M of machine tool interface engineer. Control cable, use lead and air hose means, need careful wiring and pass a machine tool, ensure thereby movement of won't cloggy machine tool or the damage that cause machine tool spare parts or main shaft electrical wiring and air hose. Normally need uses custom-built bracket to secure these main shaft the machine tool to go up. Be in their pile next the coping of module of existing cutting tool. Will carry away the central line of cutting tool from slideway sleeve by additional clamping apparatus, this will affect stiffness and affect precision finally. Main shaft speed uses the potentiometer that is located in remodel controller to go up or air valve to undertake choosing, can make switch flexibility is reduced, and connecting general reason condition fall, an outfit that has experience places personnel, ability of need 4~5 hour is installed and adjust good main shaft gives accurate part with treatment. But, the advantage of high rotate speed was head and shoulders above the defect of these main shaft. the workshop of efficient to need cutting, process designing member appropriate rotate speed can choose on small size broach and milling cutter, raise feed rate 3 or fourfold, can use the personnel with fewer fewer even machine tool to realize taller productivity thereby. Brief the vice-president Eddie Pena that the masked director that place 3D makes says: "The biggest problem that we face is, the machinist that has experience is too little, their time drag in arrives each respects. To enhance competition ability, outfit clip must become handier, make the operator with scant experience also can master easily, let seasoned machinist solve bigger problem thereby. " the company is beginning to use new technology now, and the method of main shaft of high speed milling with different choice will solve this problem. 3D company is medical treatment industry and the new across that arise to be aimed at identity identifying to match a technology to make a part. It completes many engineering design and development work for its client, the treatment service that provides finally for them increases value. A lot of clients should seek 3D company, because it machines a respect to have higher capacity than most company in small part,be. It produces bone bolt, dentistry equipment of embedded content, medical treatment and tool of imperceptible medical treatment, all these need to use a diameter to be less than 0.

062 inches milling cutter undertakes complex milling. Typical " bolt is received " main shaft of type high speed, cannot satisfy the requirement that Mr Pena is in 3D company. This company and OEM and agency cooperate, so that find out field of contented 3D application,add up to the different method of need. The question that tries company of new thing 3D gets understanding after its newest L20VII machine tool arrives definitely, this machine tool deploys high speed across to get cut and milling main shaft, it is Xi Tiecheng user to develop by the Genevieve Swiss Industries that is located in Massachusetts Southampton and PCM Willen combination. The advantage with these new the biggest main shaft is, they are special design for the high speed milling on Xi Tiecheng machine tool. Use the machine tool of box of slip main shaft, the advantage of its structure is, the support that uses slideway sleeve can machine long spare parts successfully. If these plan institute are shown, accessory of high speed milling can stand by the fixed position below the circumstance of slideway sleeve in cutting cutting tool, reduce bending thereby and get optimal applying. Main shaft of PCM high speed can replace subrogation to win the bid to allow Xi Tiecheng main shaft and need not add special fixture at combining slide carriage. Because main shaft of PCM high speed is direct by drive of actuating device of Xi Tiecheng milling in order to offer most high-power and torque, because this need not use lead and tube. The advantage of Switzerland machine tool depends on what slideway sleeve offers propping up. Main shaft of PCM high speed keeps the distance that with Xi Tiecheng main shaft leaves slideway sleeve is identical. Can maintain cutting tool so to stand by sleeve as far as possible, assure the biggest tigidity and precision thereby. When be asked about to use PCM main shaft to have what advantage, mr Pena replies: "Faster without oscillatory, cycle, raised beautiful sex and improved cutting tool life. " Mr Pena is attributed to these advantages the design, close together ground carries cutting tool ministry and slideway sleeve coupling, reduce dangerous extend, assures tigidity. In addition, because this unit is of gear drive, higher rotate speed and better torque union are together, can make sure taller milling is mixed auger cut efficiency. Citing uses to be located in bone drill (material is 174PH character) the root of knife of 6 horn drive that go up makes example, mr Pena explained how the company can be passed raise main shaft rotate speed and feed rate, use 0.

25 inches establish milling cutter to machined milling cycle to reduce 50% . Mr Pena says, 3D is to achieve so it is faster treatment cycle and taller productivity. But, the company did not think of to be in at the same time exterior precision or fall the improvement of the generation of burr respect. Mr Pena says, whether can the exterior quality stand or fall of the spare parts achieve the public errand of a hope to have very big effect to the client. His complement says, main shaft of PCM high speed had helped 3D company enhance his competition ability through achieving taller exterior precision. Machinist people can use the cutting tool with larger size, because bedspring chuck is bigger, and they can raise the limit and do not have flutter or vibration. They cannot realize this with main shaft of other high speed. For Xi Tiecheng machine tool process designing operates the Chipper Pena of this kind of machine tool to say, this produced another problem. Everybody wants to undertake with these main shaft his outfit is placed, this need does constant clever processing, because the machine tool amount of this company wants,compare high speed main shaft much. How does 3D company use his an example of new accessory, it is to be in to be used at securing the bone bolt with sutural surgery to go up to have the profile modeling mill of complex form. The diameter of the spare parts is less than 1/8 inch, establish milling cutter diameter for 0.

030 inches. Bending gets elimination almost, let establish milling cutter to stand by slideway sleeve treatment, increase to 12, the speed of 000r/min can reduce cutting pressure. Be in even 2.

4 inches / minute on speed, the result of generation is spare parts burr decreases, tolerancepublic errand controls improvement. Another spare parts that Mr Pena mentions, be those who be used at articulatory surgery is medical axis. Finished product is 3/16 inch 174PH stainless steel of the diameter, amount to 17 inches to grow almost. In the process that machines on company Xi Tiecheng machine tool, include to machine along milling of direction of 7 inches of length 0.

08 inches chamfer. The extreme of the spare parts has 0.

062 inches of windows, be being machined with the flank milling of internal diameter across and become. The rod that the photograph shows is used at articulatory surgery, grow for 17 inches. Among them chamfer is with 15, of the rate cut of 000 R/min, and treatment comes out do not have burr. Use old technology, this window is used 0.

Head of 062 inches of balls stands milling cutter with 5, 000 R/min rotate speed and 1.

8 inches / minute feed rate treatment. Machine this window to need 45 seconds only. After change technology when 3D company and adding main shaft of PCM high speed, rotate speed rises 15, 000 R/min, feed rate rises 4.

2 inches / minute, cutting time is reduced 60% , it is 18 seconds only. Another advantage are the spare parts has any burr hardly, surface of the rest spare parts does not have any flutter traces almost. What the photograph shows is the applied occasion that accessory of high speed milling uses at making bone bolt. Rotate speed is 12, 000 turn / minute, have bending hardly. Mr Pena is right other the proposal that adopts high speed to machine personnel to put forward is, beautiful money buys appropriate cutting tool, do not withhold somewhat in rotate speed and feed career respect. Make cutting tool comfortable get its place, you invest truly implementation the biggest change. CNC Milling
