Buying new machine tool often is to fulfil the treatment contract of some kind of specific work. But, besides satisfying this objective, still can score additional gain normally. This is Sterling Engineering was investing two strong vertical to turn tower lathe (VTL) , contain two very new to them option: After dynamical tooling and high-pressured refrigeration system, what they discover " appreciation " place, include to reduce setting, brief chemical industry to make circuit, raise high yield can, even still safer workshop produces an environment. Additional, this factory still drew the experience lesson that acquires when using these two functions, continue to use these machines effectively. "Although we are for some kind of specific task and buy these machine tools, they also make us new think really, how can be we improved when processing other work, just can accomplish treatment rapidder, the frequency of the setting is fewer. " general manager Chris Haddad says, "Had these new functions, it is very difficult before that we are opposite now the work that has done had quote capacity. Because more works can be done on a machine, material carried a quantity to also decrease, reduced us the production cost of every spare parts. Dynamical tool makes we can be machined directly and the detail that must move work of the rework on another machine tool before, this saved a large number of time and manpower; and high-pressured refrigeration system raised material purify rate, cutting tool can linger on blade time is longer, the probability that bit damages also was reduced. These two vertical turn tower lathe is behaved perfectly, improved our integral work flow. " graph cover of this kind of 1 exhaust once needed extra step to machine keyway, go up in VTL of machine of flourish cropland essence now, the fame Sterling Engineering that this keyway Sterling can machine then after turning is located in the Barkhamsted of administrative division of division of Kang Nie surname, held water by tool manufacturer John Lavieri and his little brother Daniel 1941, it is factory of mould of tool of a diminutive originally, the Vought Sikorsky company that is engaged in developing pirate type opportunity for combat with only at that time cooperates. Small plant develops gradually, its are made from the tool mainly change a contract to treatment. But it from beginning to end Xikesiji the company regards as big client, additionally still general and Pu Hui, GKN, electric, MB Aerospace and American aluminium course of study wait. Besides basically involve aerospace besides, sterling also serves to be mixed at generating electricity heavy industry market. Since March 1, this company became headquarters to be set in the wholy-owned subsidiary of the Air Industries Group of bank of bay of new York city. Bade 2012 after new job, mr Haddad and his work in the same placing studied equipment battle array carefully, consider as moment to invest new vertical lathe. This will promote their capability, simplify treatment craft, the more complex geometry figure that helps them machine a place of its aviation client to need. They begin to examine a machine tool to reach its at present can applicable corresponding function, fulfilled new contract then, craft should upgrade instantly. "The contract is decided via knocking, have new sense of urgency, " Haddad memory says, "Add a function newly because of what new machine tool of its hang on offers especially. We know to should narrow as soon as possible await choose machine tool roll, make a decision, so that begin,machine this kind of spare parts. " fortunately, at this moment Chicago of as it happens holds international to make technical exhibition (IMTS) , very good opportunity inspects lathe of a few kinds of vertical carefully, with its original equipment manufacturer and cent sell business to communicate face to face. In exhibit 15~20 looked around during the meeting exhibit hind, mr Haddad decides to put the emphasis in 3 kinds of machines eventually, his research makes clear, they can satisfy the requirement of Sterling. Right now, real work began. Fulfil his duty to investigate exhibit can provide a few strong machine tools, if treatment of center of numerical control horizontal, vertical counteracts turning center, sticking the mark of original equipment manufacturer, include Jidingsi - gram of Liu Yi Si, DMG MORI, campstool, Pu Hui, Gray and Xinxinnadi - rice pulls Ke Long. Mr Haddad discovers the Asia comes the manufacturer that IMTS ginseng exhibits increases significantly, and exhibition quality is very high, he feels very astonish. In his equipment the search is seleted list in, one is to be in Japan, another is in Korea, the 3rd is in China Taiwan. Be based on the introduction that sees in Chicago place, he contacts the cent that is in the United States to these 3 kinds of products to sell business, inspect their performance quality, collect its technology standard and enquire in detail. Once he has an opportunity to visit center of a technology, those who see him considering bought machine tool is actual move demonstrate, be in another place, he still visited a final user, got this machine tool true the feedback that move. All these he is connection of the phone that be passed by recommend hind. "We should consider the price and applicability of course, but after all we finish after these research, redo decision is very simple. " Haddad says, "We discover, machine of machine of flourish cropland essence besides mix formidably accurate outside, its design is very convenient to operating personnel, operate lumbar back won't be caused to pull injury or other harm when workpiece. " machine of flourish cropland essence limited company is east the member of group of stage essence aircraft, headquarters is set in Taiwan Kaohsiung city. Be in the United States, its product agrees by Maine CNC Systems distribute of Nabangke. Although machine of flourish cropland essence basically produces lathe of numerical control vertical, but at the same time it also is carried for aerospace and ground wait for the market to produce vertical turning center, high speed getting to cut center, vertical grinding center and complete product line, include a robot. The president Stephen Arcari of CNC Systems assists Sterling to make a decision. "I understood their requirement, suggest they consider center of turning of VL-160CM heavy-duty vertical finally. " he says. Mr Arcari says, 3 axes vertical turns the technology of tower lathe is normative, include 78.

7in(1in=25.

Of 4mm) the biggest swing and diameter of the biggest cutting, 49.

The height of the biggest cutting of 2in. The work that this machine can handle hefts 17600lb(1lb=0.

45kg) , have the unit changing a knife of a 16 unit. "Hang on of machine whole tigidity its Mi Hanna is cast-iron base. " he says, "VL-160CM has strong costal region form, vibration and heat can decrease to be out of shape in heavy-duty treatment process. " make a decision, consign machine, if the option after carry out installs high-pressured refrigeration system and abecedarian to groom finished 2013, the company prepares to begin to receive new order. Shift gears strategy still has an example to also explain to undertake study ahead of schedule is very worthiness. Mr Haddad ever also had considered to be able to lose order likely before investing these machine tools, think how to turn with two vertical tower lathe completes existing work more efficiently, seek new business even. As a result of this kind of foreknowledge, the machine tool is done not have unused. In the first Rong Tian vertical of machine of essence of life turns tower lathe was installed about after half an year, of Pu Hui before contractor Brian Bidwell joins in Sterling, hold the position of the production engineer of process designing of responsible numerical control. In fact, new machine tool is one of reasons that attract him to this position. When Mr Bidwell reachs a plant, the company has begun to allocate new job to give these the machine tool, so he gives himself placed job, it is everything what endeavor to learn hereon lathe, especially how can these two functions just get be developinged adequately. Imagine not hard, vertical turns be like,carry out on the same table machine tool that the main shaft of tower lathe allows to undertaking turning works milling such program. "For example, we have an exhaust cover, need machines a keyway (graph 1) . If do not have dynamical cutting tool, must move work to another machine tool, make a series of outfit card, very time-consuming. Now, it is much only an operation, can undertake on same table machine tool, need not redo setting. " he still points out, process irregular form, for example another kind when the company produces has part of egg form internal diameter, the method that can have than using with dynamical tool is faster, easier, more accurate. Return the profit that some expect are less than additionally, include the worker's security. "We are considering to machine spare parts of a kind of massive, need is all round its get with proper point of view a series of aperture. " Mr Haddad says, "The vertical that drives power tool is had to turn in us before tower lathe, we ever had wanted to suspend work on workbench, get on horizontal boring milling machine. We will must use sleeve main shaft, so the prolapse of cutting tool is a main problem. Operate personnel general to must use elevator shift work in order to get the equal seat of bore. And this is an issue that considers from safe angle merely. Now, how can we turn workpiece in vertical on tower lathe, very stable. The affair that we can attend to make all need in a machine tool finishs. The time that great work locates afresh is less, jump over safety in the everybody of this area. " the high-pressured refrigeration system here is ChipBlaster JV-40, the greatest pressure that it provides is 1500psi(1psi=6.

895kPa)(graph 2) . Mr Bidwell says, its main good point includes to discharge bits. "The certain part that we produce is familial have deep chamfer, its craft should produce bird's nest model cut bits, can destroy cutting tool way very quickly, cooling system conduces to break up cutting bits, clear method, make we can continue to machine detail. " graph cover of this kinds of 2 exhaust once needed extra step to machine keyway, go up in VTL of machine of flourish cropland essence now, this keyway can be machined then after turning other good point still has, the air that can penetrate the likelihood appears between surface of sparge of cooling fluid of low or medium pressure and workpiece cuts off, conduce to medicinal powder hot, prevent workpiece and cutting tool be out of shape, carry accurate noncombatant duty, bring the exterior surface roughness of high quality. Cooling fluid eject conduces to found low and firm temperature environment, be helpful for cutting tool staying in blade longer work with rapidder cutting rate, the chance of bit occurrence attaint is less. "This conduces to treatment really we the treatment of this kind of large work, what this chronometer calculates is ' every workpiece uses a few bit ' , is not calculative of the place when processing little work ' every razor blade a few workpiece ' . Because change their cost is very high, so the service life of these razor blade should grow as far as possible. " Mr Bidwell continues to turn in new vertical the test is done on tower lathe, especially dynamical tool and the additional capacity that cooling system can provide maximum pressure, think method machines existing spare parts more efficiently ceaselessly, at the same time also the patulous function that these machine tools provide have the aid of and its high-tech option, attract new client. Graph 3 " solid is locked up " when lesson of experience of system of cutting tool clamp should speak of the characteristic of dynamical tool, mr Bidwell points out, important experience lesson basically is in 3 respects: With mode of polar coordinates interpolation (G112) still uses a dot to undertake process designing to nodding mode. "I try at first need not process designing of polar coordinates interpolation all cutting, but discovery very what should Qing Dynasty of it's hard to say do. " he says. "Polar coordinates interpolation is concessional with simpler code, more be similar to common process designing of 3 axes milling machine, such jobs that I can rely on a machine tool to control a system to do much. We still use a dot to do drill to the dot kind exercise. " how to make full use of limited cutting tool ability. "To aperture go burr operation, I change two cutting tool that use treatment coping and radius of bottom circle horn to use cutting tool of a Heule COFA. This can let finish machining of a cutting tool the two side of this aperture, saved the space in rotary table. " Mr Bidwell says. In respect of high-pressured refrigerant system, it makes cutting tool of pottery and porcelain has stabler cutting. "Mensurable cooling fluid makes be like,be in chromic ferronickel alloy 718 or Haynes the service life of the razor blade of pottery and porcelain in this kinds of 188 super alloy is a few longer, we can provide 1~2min in blade push broach before rotate. When burden rough machining works, improve productivity with cutting tool of pottery and porcelain. " bits of deep chamfer platoon is improved greatly. "In circumstance of a certain application, although cutting tool is to be in the trench with deep 3in when, I also can cut bits to produce. " his explanation says. Adjust nozzle correctly refrigerative fluid in season is very important on edge. "Otherwise you can get its in season is in only is. " system of clamp of rigid to proprietary of machine of flourish cropland essence cutting tool also likes Mr Bidwell very much, it has exceed big Z axis cast steel " strike a head " , of buckjump coupler and T pull rod, realized cutting tool of on the safe side, programmable to secure. "We discover, we can duplicate vintage vertical turns tower lathe is used ' solid is locked up ' the heavy-duty cutting that place of clamp cutting tool does (graph 3) . This is very stable. Taller tigidity makes vibration little, can realize better exterior surface roughness and longer cutting tool service life finally. " graph 4 this finished product reveal the detail that VTL can realize a machine of essence of cropland of a lot of flourish, use the hole that dynamical cutting tool gets out for instance, and by the high-pressured refrigeration system of the machine tool cut bits worrily to clear the deep trench that come out CNC Milling CNC Machining
