Apply Yu Shuang to turn the design of erect type lathe bed on tower lathe, be helpful for raising an axis kind the turning of workpiece machines precision. When turning is machined, a four-axle double turn tower lathe should turn than sheet the effect of tower lathe is one times taller, still arise at the same time times more cut bits. Because installation turns in fluctuation,this is the cutting tool on the tower can undertake cutting at the same time, just among them one turns the tower should turn than another tower a little lag a few, because these two turn,the tower moves towards work way. Of lag turn the diametical contact of the cutting tool on the tower and new cutting, bring about this to turn the cutting tool of the tower is left behind. This kind double turn tower lathe, have lathe bed of inclined of a bend for the most part. However, mr Gore is company of machinery of Fuji of United States of Fuji Machine America (be located in Yilinuosi the Vernon city of the city) district selling manager, mr William Gore points out, this kind of design can let what the cooling fluid of many eager bits and be heated centers below turn tower area. He says, this kind of design can affect the treatment precision of this kind of lathe and service life conversely. Mr Gore explanation says, as a result of the influence of be heated medium, the lathe bed of lathe may be heated and expand, the turning that affects lathe thereby machines precision. This kind of circumstance also can quicken slideway rub-up implement malfunction, cause slideway adjustable felt and a leak. Will naturally make guide screw and slideway expose Yurejin to belong to so cut bits in, bring about the maintenance with more frequent machine tool to damage even the main movement component of the machine tool. The ANS series four-axle of Fuji company double turn tower lathe uses erect type lathe bed to design, can let those who cut bits and cooling fluid to enter a machine tool directly cut bits to carry implement inside (graph 1) . Mr Gore says, below such circumstances, the material of be heated won't build up to go up in crucial component, make the machine tool can maintain enough precision for a long time. ANS series machine tool is pushed after exhibiting on IMTS 2008 exhibition to American market, deserve to a collect becomes manipulator of type of door of double axis dragon on this machine tool, the automation that is used at workpiece assembles and unassemble (graph 2) . Graph 1 four-axle double turn tower lathe uses design of type of erect lathe bed, can let those who cut bits and cooling fluid to enter a machine tool directly cut bits to carry implement inside the graph deserves to have a compositive Shuang Zhoulong on 2 machine tools door type manipulator, the four-axle of automatic and masked discharge that is used at workpiece double turn tower lathe uses the treatment application field between Yu Changshi normally, because the tone trial assembly of its workpiece blocks time,should compare sheet to turn tower lathe is a few longer. Mr Gore says, because ANS series machine tool deserves to one is cover but process designing is followed move wear and tailstock, accordingly it agrees with treatment differs into series the axis of length kind spare parts, do not need for many times to move trial assembly to get stuck. Operator can move the course that takes a new part very simply, and machine tool criterion can will follow automatically move wear and tailstock adjustment arrives agree with the correct length that processes that work. (Generally speaking, the requirement is more than 10:1 than answering along with what move a length with the axis and diameter) . Such, the workshop can machine all sorts of compound spare partses effectively everyday, is not treatment large quantities of axes that estimate onefold breed and size kind spare parts. This is helpful for reducing the workload in process, finish quickly assemble the task, the axis because of all and necessary dimension kind the spare parts is OK immediately a consign assembles a workshop to use. The X axis of ANS-300TT lathe and Y axis journey are 110mm and 480mm respectively; And the X axis of ANS-320TT lathe and Y axis journey are 85mm and 735mm respectively. The main shaft diameter of these two kinds of lathe all is 100mm. CNC Milling
