摘 要 365数控车床是以整机架放入车床的定位（装夹）驱动座上进行三辊分别加工孔型的方式，所加工出来的孔型中心对称度好、是任意曲线类型的孔型，弥补了Meer专用孔型车床只能加工椭圆性孔型的局限。实现了德国kocks机架孔型将与Meer机架一样不拆卸下轧辊就能在车床上直接进行孔型的加工。这是国内张减（定径）机架孔型加工的一个突破性的加工手段。 该装置是属于机械金属切削加工类机床，主要用来对钢管生产过程中所使用的三辊张力减（定）径机机架内的轧辊孔型进行加工。其主要特点是采用数控轴联动的伺服控制，能够实现分别对机架内三个任意曲线轧辊孔型进行整体车削加工。 365数控车床的突出点是：采用刀具与数控轴同时回转换位的方式。实现了一根数控轴，可供三个加工位置的共享。只使用两根数控轴的联动控制，就可实现与三轴联动数控孔型车床（第三代）相同的加工形式。其实能做到这点，完全取决于张减（定径）机架三个轧辊有规律的轴线平面均匀分布，且为中心对称体关系。充分利用了这个特点，可以做出了卓有成效的机械设计方案，以非数控机械控制替代了数控轴的控制。 本设计介绍了国内国外数控车床发展的过程与现状，并分析了其存在的问题；对数控机床的发展趋势进行了探讨；并对365数控机床轴向、径向进给传动系统及微调系统进行了设计。 关键词： 数控车床； 传动系统； 轧辊孔型加工 Abstract 365 CNC lathe is the whole tray in the positioning of the lathe clamping driver seat three-roll processing pass, the processing out of the hole center Symmetry, it can curve any type of hole pattern which make up for the Meer pass lathe oval pass can only process limitations. The Germany Kocks rack pass Meer rack without disassembling the next roll will be able to directly pass on a lathe processing. The force reduction sizing rack pass processing is a groundbreaking means of processing. The device is mechanical metal cutting machine tools, mainly used steel pipe production process used in the three-roll tension less be rack sizing mill roll pass processing. Its main feature is the use of CNC axis servo control, able to achieve the overall turning the rack three arbitrary curve roll pass. 365 CNC lathe salient points are: the use of the tool and CNC axes way back to the conversion bit. A CNC axes, available in three machining positions shared. Using only the two CNC axes linkage control can be achieved with axis linkage CNC pass lathe third generation the same form of processing. In fact, this can be done depends entirely on the rack three rolls laws of the axis of the plane sizing the force reduction evenly distributed, and symmetric body-centered relationship. Therefore, take full advantage of this feature, can make effective mechanical design, CNC axis control alternative to th
