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
