Auspicious of German heart horse (DeckelMahoGildemeister, DMG) development went workbench corner coming back to spend old 5 axle control formula machining center (MachiningCenter, MC) -- DMU50eVolinear, be on sale at the machine tool that 6 ～ were in American Chicago city 13 days to hold in September 2006 meeting IMTS2006 (Chicago is exhibited) on showpiece. This product uses thin arm trunnion, tilt ground installation is on airframe. Accordingly, can tilt clamp of clamping apparatus of have the aid of in the workpiece on workbench to - 18 ° undertake cutting. The trunnion that this company place uses, along with the workbench that its upper part bears the weight of is called commonly " SideMountedTrunnionable " . Popularly, trunnion submits cradle form, two side installation is on level or perpendicular direction, new trunnion can rely on to odd side is propped up and rotate only. Because the installed surface of trunnion has inclination, so if for dislocation rotational trunnion, can tilt workpiece syncline upper part or inclined lower part freely undertake cutting. Rotational workbench cooperates while through be in additionally trunnion rotates, still can realize horizontal clip to hold work. Below this kind of circumstance, if use a choose and buy at the same time tailstock turns at the same time workbench, can install cutting tool the turning that undertakes length workpiece in main shaft side. This kind of trunnion circles B axis (Y axial axis) rotate, corner coming back is spent for ＋ 90 ° ～ - 18 ° . And workbench circles C axis (Z axial axis) do 360 ° to rotate. Through rotating and the rate that roll has dislocation is rapid also be one of its characteristics, the roll of trunnion (rotate) speed is 40rpm, the rotate speed of workbench is 50rpm. Because used structure of trunnion of thin arm type, airframe is more cabinet. Dimension is only wide 2186 × are entered deep 2720 × tall 2510mm, can save installation space. MC uses vertical structure, but along X axis, Y axis, Z axis 3 direction move. Among them, x axis introduces linear and motor drive, raised rate. The fast feed rate of X axis rises the biggest 80m/min. In addition, the feed speed when cutting came true to be achieved at the same time on 3 axes " the biggest 10m/min " (Demaji) , rose to machine efficiency thereby. Change in automatic cutting tool device (ATC) respect, be located in the pincers of two end through using clip to hold position, raising cutting tool to change dependability while, shortened change the time that cutting tool spends. From tear open next cutting tool to arrive till cutting tool of mount the next, what need time " it is 5 seconds only " (Demaji) . Spare parts box accommodates cutting tool amount to be a standard 30. Additional, as the choose and buy the spare parts case that Demaji still prepared 60 outfit and 120 outfit. In addition, the main shaft rotate speed of new product is standard 18000rpm. In rotate speed respect, the main shaft choose and buy that De Maji still can offer 24000rpm and 42000rpm. Regard treatment as object workpiece, this company still showed head of car axle bracket, milling cutter (main body) , the titanium alloy that cure choose and employ persons makes one of parts of knee joint, plane controls valve base (ValveBlock) , F1 (cycle racing) oil pressure component and tire mould.
