Composite treatment system can let car component manufacturer raise high yield gradually as the addition of demand can, and won't throw into confusion the manufacturing rhythm of whole factory. Visit an any cars to produce a plant, you can see a few common production facilities commonly, arrive from modular machine tool flexible the machining center system that change. Now, a kind of new treatment system is appearing sadly in car production workshop. Flexible Composite treatment system is comprised by agile modular machine tool and heavy-duty horizontal machining center. Machining center basically accomplishs major treatment task in this system, and the finish machining that other and special machine tool basically is in charge of a few keys. The biggest gain of Composite treatment system can allow manufacturer namely as demand increase to raise high yield gradually can, and won't throw into confusion the manufacturing rhythm of whole factory. In addition, manufacturer still can control the investment of equipment well, the initial stage that can begin a plant with inferior yield runs. This is Mixiegen city Redford area wears Mu to force a company -- company of Detroit diesel engine (Detroit Diesel Corporation) adopts strategy. The efficiency that the Composite that company of Heller machine tool offers machines a system to helped company of Detroit diesel engine raise body of diesel engine air cylinder to machine is aimed at his new-style DD15 is heavy-duty engine platform, company of Detroit diesel engine divides a phase to invest millions of dollars in all, bought the treatment equipment of body of diesel engine air cylinder, include the treatment system of a Composite namely among them. This kind full automatic system of dragon door treatment is in charge of machining this factory 1200 pounds are special the cylinder body of cast-iron diesel engine of the brand, divide a treatment measure in all, after finishing, can undertake assembly. Whole treatment system includes machining center of a few heavy-duty horizontal, one can change center of knife head CNC Machining and a few agile modular machine tool. Adopt this system, the production below the case that company of Detroit diesel engine can have adjustment in incorrect equipment amounts to 32 kinds of different engine type. Initial stage is started in the project, same fixed position and outfit clip dot come down certainly on the cylinder body that development department of product of company of Detroit diesel engine thinks to be necessary to there is type in place. Final, they designed DD15 engine from the feasibility of treatment. To advance the progress of this project, company of Detroit diesel engine still built cooperation with company of Heller machine tool. Production of company of Detroit diesel engine manages manager David Mitchell to express, heller company acted important role in whole project, mix in the 11L that has same fixed position and outfit clip to nod, 13L especially 15L engine had indispensable effect on the design of treatment feasibility. Cylinder body of these a few engine can use above identical clamping apparatus, the management of output of product of this pair of same type is very crucial, still can let company of Detroit diesel engine produce the product of different type on same product line at the same time. The mainest facility in system of this Composite treatment is machining center of Heller MCH-400D horizontal, prism body work can is aimed at to expect up and down directly in same treatment system. The treatment area of this equipment can be accommodated 1.

45 meters long diameter is amounted to 1.

68 meters treatment workpiece. In engine cylinder body the first pace is machined in, heller machining center undertakes milling to crankshaft semicircle aperture, to around face, underside and bearing lid the face has thick mill, still be in charge of bore. Next Heller HCS 450D uses assorted milling cutter to be opposite milling undertakes next door engine cylinder body. Same area of the system is machined in Composite, flexible and automatic product line tightens a Heller to have face mill to the back end of cylinder body trunnion then. In operation of this one crucial treatment, use angle head to carry milling cutter. Car manufacturer uses CNC Machining center increasingly (on) with modular machine tool (below) the production that will have engine, former and OK the treatment that is satisfied at needing to often change, and latter is used at changing not much treatment. NextpageMitchell expresses, an advantage of Heller treatment system is thick next door cylinder body mill used in this one crucial treatment can change the milling machine of knife head. Undertaking cutting tool changes so while the machine still can continue to run, increased manufacturing efficiency so. Mitchell still states other equipment supplier once suggested to use a kind of special device, but changing still is to should stop a machine when cutting tool. Next working procedure of treatment of 6 cylinder body is finished by horizontal machining center, finish fluctuation to expect by Liebherr dragon gantry crane. To assure the norms of tolerancepublic errand and workpiece, heller adopted the way that measure workpiece puts larger prism form cylinder body to press order to undertake machining in machining center. Next, cylinder body workpiece is carried the flat bottom boring of aperture of the thick mill of head of the precision work that undertakes to machine of a MCH-400D air cylinder water is covered, air cylinder and flange face, flange is gotten, and the thick boring of air cylinder internal diameter. About the treatment of thick boring of air cylinder internal diameter, the standard machining center that Mitchell points out to Heller company is offerred contains device of activation of cutting tool of an U axis, can cover to cylinder body water undertake bottom cutting. He points out the equipment of other vendor did not provide a such functions. Next, equipment of a MCH-400D bores hole in air cylinder head and underside and tap, install end panel to have mill of essence of life to underside and bearing lid next, then the gun drills lead plane oily hole and to side upright lining has mill of essence of life. Next, engine oil aperture gets means to finish through the gun, boring of reaming of bottom of peace of the underside bore that finish, tap is gotten. In Op 70 working procedure, cylinder body controls both sides to finish aperture of bore, bore with a reamer and tap. In the area of the last treatment of this system, face of cylinder body around finishs bore, tap and aperture of bore with a reamer, in addition use milling cutter of angle head head to undertake horn is machined. Flexible and automatic product line finishs Heller next the rest of treatment. Automatic product line is used flexible those who change can configure equipment unit, installation is on standard equipment. Heller undertook these unit interfaces standardizing, such unit related to workpiece, be like tool carrier and clamping apparatus, can get use in whole treatment process. In addition these automatic product line still had a characteristic to use the control that furnishs oneself to stand namely, use dispersive control principle. The design concept of the flexible and automatic product line of Heller company is the set that can adopt a program undertakes be configuringed afresh to the machine tool, can bring inferior whole to have cost to the user so. Heller expresses, whole has cost to want to consider the capital investment with initial facility not only, the maintenance that considers the equipment inside whole use cycle even and maintain cost. And it is very important also to reduce machine down time. In the Op120 of penult working procedure that machines in cylinder body, flexible and automatic product line uses coaxial and poriferous boring to lever undertakes boring of essence of life to crankshaft aperture and gain thrust bearing face, didymous aperture diameter is over in the meantime measure. A flexible and automatic product line undertakes to face of cylinder body front mill of essence of life is machined, then deferent equipment carries cylinder body the next to machine equipment -- MCH-400D, to flange end undertakes aperture of boring getting, bore with a reamer is measured averaging a copy. In last pace working procedure, flexible and automatic product line undertakes to crock aperture finish machining is reached measure, undertake end panel milling to trunnion, at the same time treatment gives cistern. So far, cylinder body can undertake was assemblied. According to company of Detroit diesel engine Joerg Sieverding of production chief inspector expresses, the company discovers their assorted treatment line and Heller system photograph are compared, be in not only flexible producer face, there also is very big difference in respect of whole workshop environment. "Cylinder body machines the pollution of area to had been jumped over lesser, because launch aircrew outfit,go up with respect to the edge that machines equipment in Heller. Never had wanted to want before us so do. But all facilities distribution is very compact reasonable, " Sieverding says. Mitchell still expresses to will be machined and be assembled put in same area from will for a long time look to also can bring profit. Whole position can save time, assemble personnel to stand in its work place to be able to see whether cylinder body is being machined, the circumstance that because they can see cylinder body,goes up in product line, apart has 40-50 rice only probably, measure a station to also look up to see namely. In addition, all operation personnel is in in unified station a side of equipment, reduced forklift to enter the number that produces section. The collaboration of company of Detroit diesel engine and Heller is fruitful, this basically depended on both sides making be communicated deep and communicate. "Achieve such result, you need to be willing to help you design the partner that satisfies you to ask, one is willing the partner of to table a proposal. " Mitchell from the bottom of one's heart expresses. CNC Milling CNC Machining
