6 the left and right sides, to cast-iron attune of blame of the carbon in mixing pledges rolled steel expects, the bore feed that common gun gets can amount to 150mm/min. The experience of application of research and development that TBT company comes 40 years get technology to the gun uses the treatment at crankshaft oily aperture, take the lead in giving out oil of much axis crankshaft aperture is flexible machining center, will flexible and efficient machine faultlessly union to rise. Nextpage comes nearly 10 years, TBT company is studying MQL refrigeration technology gets craft to be applied mediumly in the gun all the time, pass different workpiece data contrast for many times treatment experiments, take the lead in using MQL technology successfully get treatment at the gun, development of corresponding land went a gun to get cutting tool coating and blade to grind technology of form a complete set, make machine efficiency to rise considerably further, bore feed raises 300 ~ 500mm/min. It is with 4 crocks of crankshaft of sedan exemple, treatment content cuts all straight inclined oily aperture and orifice to get, oily aperture of crankshaft of axis of a TBT3 year of productivity of machining center more than 200 thousand. 2. The clamping apparatus that uses Gao Rou sex (see a picture 2) , improve process centralized degree, broke machine tool process capability to be opposite the confine of crankshaft norms dimension. Graph the clamping apparatus clamping apparatus of 2 Gao Rou sexes can follow workbench 360 ° rotate, be versed in in order to adjust the opposite point of view of workpiece and cutting tool and working station and fluctuation makings changeover; There is workpiece to rotate on clamping apparatus actuating device, machine in order to realize week of bore that differs to the position; The tip of clamp of rear push frame that numerical control locates can undertake adjustment according to the length of workpiece; The radial fixed position of crankshaft adjusts implementation through numerical control; Sealed card claw passes orifice what numerical control realizes oily aperture of diameter of corresponding main shaft is sealed, in order to make when aperture is interlinked, the straight oil on inclined oily aperture and neck of corresponding main shaft will not reduce generation explosion burr suddenly because of oil pressure. The place on put together is narrated, can see machining center has TBT crankshaft oily aperture to highlight a characteristic below: ■ can install clip to finish bore, orifice to fall horn and swing dry cutting oil; ■ the crankshaft that can machine different length, different oily opening position and amount, different stroke, different width opening file, different journal, have very tall flexible; ■ breed changes to come true very easily, should change only corresponding knife complementary provide and the component such as clamp card claw, use corresponding machine program can, normally breed commutation needs 10 ~ 15min to be able to come true only. 3. Use auger set form enclosed gun to get treatment course. Graph 3 get set enclosed oily aperture of treatment TBT crankshaft of machining center get an installation to be on the box that discharge bits, surface of clingy workpiece, the aperture of straight oil of main shaft neck that intersects with the inclined oily aperture that machining is encased closely by sealed card claw, cutting oil leads to cutting area through cutting tool interior, next with cut bits to get the chamfer that discharge bits and the space that get inner room to discharge in the box that discharge bits through the gun together, the treatment process that fashions to close relatively (see a picture 3) . This kind of method basically has the following advantage: ■ auger set beginning to get fashionable have oriented effect to broach, oriented hole need not be drilled beforehand in workpiece surface when the gun gets bore, shortened consequently treatment process, reduced finished cost, and won't appear in orifice aperture of a flight of stairs; ■ the environment that close makes cutting fluid, cut bits and oily mist to be able to discharge the box that discharge bits only in, won't fall to workbench to mix in the machine tool, reduced cutting fluid use up, reduced the working intensity of machine tool cleanness, of facilitating oil mist draw-out, be helpful for environmental protection sanitation. 4. Avoided to machining circular process to undertake changing a knife, shortened greatly bide one's time time. This machining center was deployed auger set change device is replaced get oriented aperture cutting tool, every main shaft is replacement of 5 different point of view or length get set, auger set in changing to adjust a process in below treatment one position, undertake at the same time. 5. Monitoring of executive treatment process, avoid cutting tool to wear away. This machining center basically changes through feed pressure and drive power changes means of two kinds of monitoring comes to those who avoid cutting tool wear away: ■ the supervisory and control arrangement of ARTIS cutting tool that configuration belt learns a curve, set power maximum and span of limit of the least value; ■ or supervisory and control arrangement of cutting tool of configuration BLUM laser; ■ or supervisory and control arrangement of pressure of configuration SANDVIK feed, install feed pressure maximum and span of limit of the least value. The place on put together is narrated, machining center has sex of TBT crankshaft oily Kong Rou very tall flexible, process capability broke crankshaft the confine of specific norms, and manufacturing efficiency is very tall, accord with the metre of big batch product line completely to ask. Current, in the whole world already in the machine tool of treatment of crankshaft oily aperture that consign uses, TBT company is the mainest supplier, foreign user basically includes Daimler-Chrysler, BMW, Porsche, VW, VOLVO, Renault and Triumph Motorcycles to wait, chinese user has Shanghai wood of bell of river of morning of general, Shenyang China, strange luck, prosperous and one steam engine the factory.
