If company of car component production wheres does intense market occupy position in competition? Without doubt. Advanced production technology is crucial. The need that in the light of car component large quantities of quantities, much breed produces, what Inc. of machine tool of case of German Sa horse developed 1-3 main shaft is flexible treatment is unit (FMC) , solved car component effectively in high grade, efficient production " bottleneck " . To solve car component effectively of high grade, efficient production " bottleneck " , what development of company of pattern of German Sa horse went 1-3 main shaft is flexible treatment is unit (PMC) , of the efficiency of private plane of collect of this series machine tool and machining center flexible for an organic whole, can satisfy the need that automobile industry big batch produces already, have machining center to be changed quickly again those who produce is flexible characteristic, also can choose corresponding workbench and knife library by the requirement at the same time, come true thereby polyhedron, complex model the treatment of face and aperture. Reasonable design   1, the demand that tall dynamic tigidity reduced to assist time to be stability of contented and contemporary machine tool, FMC lathe bed used Hydropol data. Compare with traditional data phase, this kinds mineral base cast has better thermal stability and larger thermal capacity. The machine tool structure of tall tigidity and Gao Kangzhen sex can make the spare parts obtains better appearance to machine quality. In addition, two pillar were installed in the rear of lathe bed, door form is taken of on the perpendicular slideway of pillar what actuating device and hydraulic pressure weigh equalizer is dangerous extend workbench. When changing a knife, dangerous extend the workbench blame in coexistence column area of mutual connective upside is mobile. The main shaft box of integral type can accommodate main shaft of 300mm(FMC-3 of 3 be apart) electric main shaft, pass shift of direction of axis of X of crossed slip edge and Z axis direction. Be linked together cheek by jowl the slip that decorate because its are tall trends is rigid and make equipment has precision of high fixed position and tall treatment precision. 2, the main shaft that use phone is made higher security is had in giving priority to transmission shaft to machine a process in deep aperture to assure, this series machine tool chose configuration of horizontal main shaft, the characteristic of this kind of structure is need not use cooling lubricant in great quantities, additional, workpiece suspension is on clamp device, cut bits to fall directly transverse the broad platoon bits that decorate implement inside, avoided effectively to cut bits to put stay in the box that cut bits or fall on the cant that discharge bits. On standard machine tool, advocate the configuration of transmission is high-power report main shaft, rotate speed limits is / Min of 4000 ~ 16000r, / Min of turn up 12000r, starting time is 1s about, below the starting time of 100 % , the drive power of every main shaft is 20kW(but option 30kW) . Press standard regulation, cutting tool gripping sleeve is HSK63. In X, Y, Z3 on the axis, the feed power of every axis is 8kW, feed speed is / Min of 1 ~ 6000mm, fast and floating rate is 60m / Min, the power of the circular refrigeration group of two report main shaft is 13.

5kW. 3, the means changing a knife of capture type for the machining center to the tradition, the system that change a knife is a when affect life of electric main shaft main factor. Because dirt or the meeting such as the conglutinate that cut bits bring about those who contain calorie of clincher to change knife manipulator to often arise,move by accident, main shaft axis bears to the rigid unit that change a knife hits and be out of shape, bring about main shaft to give out heat thereby and damage finally completely. For this, FMC machine tool abandoned changing knife orgnaization, the acting capture type with HSK63 clamp broach shell changes a knife. On library of traditional knife of type of dial coming back or chain knife library, because broach shell wants rapid on operation personnel the top of head movement, reason must its firmly locking, system of this kind of capture and like blocking strict formula to trade knife unit, be collided easily, and the library of disk type knife that FMC collects appliance to have function of perpendicular runner shaft coming back, plastic broach shell has project of excel in wear-resisting larger locking area, can hold the position of cutting tool reliably thereby. According to experience, when batch is produced, the program moves in the order of each called cutting tool can weave on knife library the position is piled up and memory rises. If change the whole exercise of the main shaft box that the place when the knife asks to carry out,do not have additional put through and rotate function, change knife time the the shortest, most reliable. The basic structure of the library of disk type knife of this kind of new development is by 8 have 10 knives each pectination knife box comprises, after box of a knife has been used, library of disk type knife has placed the position of box of a knife again. Send the dependability of the knife to ensure, this machine returns premeditate one reads the hand that keeps a head to move of what can identify cutting tool auxiliary send a knife implement. To rise flexible, in can classify knife box selectively or stocking auxiliary knife library, here the circumstance falls, most bolo library capacity is 150 knives, yi Kecun puts boring head (when adjacent knife is vacant, cutting tool diameter can amount to 160mm, grow 320mm, weigh L0kg) , the time that change a knife is 4s. 4, workpiece exchange time needs company of Ma Ge of 6s   Sa to use numerical control only turn board bracket replaces perpendicular workpiece bracket advocate rotor, this kind of effect discharging bits that decorates means is good, and the gravitational action of workpiece is on installed surface, raised the dependability of the process. Its design plan to be: The horizontal that wears as workpiece swings drive shaft (A axis) one aspect of the matter contains a planar gear, along with move end to be pedestal. Planar dish the diameter is 345mm, clamping apparatus crosses the clamp face of the bridge to be 960mm X 380mm. (The rear of lathe bed of FMC machine tool installed two pillar, door form is taken of on the perpendicular slideway that establishs what actuating device presses equalizer with fluid is dangerous extend workbench) workpiece exchange is to pass Z form to retroflexion 180 degrees workbench comes true, workbench one divides into two: While 2 workbench of 1 / install clip workpiece to be in treatment status, additional 2 workbench of 1 / are in fluctuation material status, clapboard segregation is used among. Because swinging jointly,the NC control that two workpiece arranged to wear each to provide independence relatively on lever swings axis, swing so the axis circles horizontal axis circumgyrate 180 degrees when, remain does not have almost on workpiece cut bits, the movement that expects up and down and workpiece treatment are OK and collateral. The fluctuation makings area that exchanges workpiece and the treatment division that head cooling fluid are kept apart by the clapboard that opens / automatically to shut. The whole area that expects the doorknob workpiece of the area wears upper part on is opened, of such nonexistent automation go up makings problem, the B axis that still one is used optionally at 5 coordinate to machine and A axis diameter are the dial of 210mm, clamp area size is 220mm X200mm. All reference axis of machine tool of FMC of   of tall treatment precision all use absolute value to measure a system to undertake metrical, accordingly position of the reference axis below any circumstances determines exclusively. All swinging the axis all uses gear of planar clench the teeth, of fork swing axial installation is on the sidewall of box form lathe bed. Installation is box of main shaft of structure of whole of 450mm report main shaft in two span, with planar cross slide block is in direction of axis of X, Y moves. It is when dynamic stiffness is taller, this kind of structure has good oriented sex. For the lathe bed null that affects to sufferring temperature easily, one has the tall lathe bed with the strong interface of lesser cooling fluid be heated, with smooth and long lathe bed look is compared, its advantage clearly. According to standard of VDI / DGQ, the positional public errand of coordinate of X, Y, Z is 12 μ M respectively, average position is spent dispersedly for 8 μ M, repeat fixed position precision to be 2 μ M. FMC need not increase special foundation, because hang,extending workbench is special pipe structure, athletic quality is very small, consequently athletic speed and acceleration rise further likely. With treatment of double main shaft unit FMC-2 photograph is compared, the workpiece circumgyrate bracket of the FMC-3 of 3 main shaft by a level place an axis (W axis) form, it a working area in be in damp area and on makings area is separated, use this to decorate a form to be able to make workpiece changes with treatment be able to synchronism undertakes, in addition, still can get first-rate to discharge bits the effect and clip work is held in order in fluctuation makings area, make an operation more safe thereby. The door of loading area is worn through workpiece circumgyrate open whole treatment area, although full automatic material is transmitted also won't be allowed why to be affected. The two side that placing an axis decorated horizontal rotor each (A1, A2) . 3 all reference axis are mixed in transmission in following a pedestal, be finished through gear of end panel clench the teeth, in tall tangential fixed position precision can come true to be when tigidity + 2" . The largest effective space that by workpiece device of circumgyrate wearing, clamp and workpiece form is 700mmx950mm, and as option, can install the two rotor that take BI-B3 of 3 runner shaft coming back (A1, A2) , realize 5 treatment thereby. The diameter can make for the big mesa of 280mm every workbench outfit places 2 parts, every workbench passes gear of end panel clench the teeth and an add clamping apparatus, be in good positional position from beginning to end, the working mesa that forms by clamp device and workpiece can offer the effective clamp range of 295nunx300mm. Machine tool of FMC of   of main application limits basically is used at automobile manufacturing industry. Be in Europe, a few main cars and component manufactory use this kinds of device mostly, in order to achieve the batch on the product, go up the purpose of class. The car component that its model machines has camshaft of / of engine crock lid, connecting rod, crankshaft (two end panel) , bearing lid, poor fast implement housing, dial forked, apply the brake the workpiece such as body of a powerful person of / of housing of pump of cent of total pump / , steering gear and supercharger, apply extensively at a powerful person of pneumatic of hydraulic pressure / kind, pump kind, the treatment of the workpiece such as cylinder body of compressor of dynamoelectric tool, freezer. FMC-2 makes the weak point that produces efficiency twice to increase   FMC double main shaft to machined unit to eliminate traditional machining center, the journey of direction of coordinate of its X, Y, Z is 450mmX 500mmX 450mm respectively, the span of two main shaft is 450mm. Machining center of double main shaft can make produce efficiency to raise 1 times above, two jobs main shaft all can use head of much axis boring to machine at the same time, make produce efficiency to be able to rise again thereby, in addition, the acceleration of the fast and floating rate of 60m / Min and 1g makes auxiliary time decreases greatly. Compare with FMC-2 photograph, FMC-3 can make produce efficiency to raise 30 % . This type is developed on FMC-2 series foundation, the journey of direction of coordinate of its X, Y, Z is 300mm X500mmx450mm, electric machinery main shaft is decorated by be apart 300mm, position of two main shaft can adjust outboard, speed speed is 60m / Min. When the article shows a watch to be total pump of apply the brake of car of spare parts of treatment model car, machining center of special machine tool, odd main shaft and treatment of double main shaft are unit (the contrast of FMC-2) treatment efficiency. The place on put together is narrated, traditional machining center satisfies large quantities of need that estimate production hard on efficiency, and private plane is shown again flexible and insufficient, the advantage collect of both of Samage FMC general at an organic whole, overcame both inadequacy, solved car component effectively of high grade, efficient production " bottleneck " . Inc. of machine tool of case of horse of Sa of Germany of brief introduction of company of office of delegate of Beijing of company of pattern of German Sa horse is one specializations unit of treatment of much main shaft of development, production, numerical control is flexible the company of private plane and end panel machining center, come for years, product of its machine tool already produced manufacturer place to apply extensively for numerous car. Delegate of Beijing of Sa horse case is in bed of extension of main representative numerical control coming back, numerical control to roll linkage of grinder of filar machine, whorl, 5 axes to establish milling machine of / horizontal machining center, of all kinds boring, honing machine and hub to detect equipment, the industry waits to have a lot of faithful users in pneumatic of treatment of aerospace, car, autocycle, tine, hydraulic pressure, standard component, if Shanghai masses, one steam masses, Shanghai collects hub of total plant of gear of car of jeep of dust inspire confidence in sb, Beijing, Shanghai, Dai Ka, Hadongan,wait. For convenient China broad user, place of delegate of Beijing of Sa horse case sets service center of user of 2 Germany machine tool in home especially. CNC Milling CNC Machining
