CNC lathe main drive system design
Abstract： CNC lathe is a precision, high-efficiency automatic machine. Equipped with a multi-station turret or power turret, plus a wide range of tools for process performance, processability straight cylindrical, cylindrical slash, arcs, and a variety of thread, groove, worm and other complex parts, with linear interpolation, circular interpolation various compensation and the mass production of complex parts played a good economic results. This design, the first of four kinds of basic transmission schemes are compared to select the appropriate transmission scheme, and part of a belt drive design, merit-based selection of the belt drive, and design of the spindle. Secondly, the main drive of CNC lathes various components of the design, including a CNC lathe spindle design calculations, design and calculation of belt drive spindle and encoder shaft bearing selection, key selection, spindle positioning fastening design, spindle bearing lubrication and seal for design-level computing. Finally, the main components of the CNC machine tool for the check, including the strength and stiffness of the spindle, bearing life, were checked.
Key word：CNC lathes; main drive; drive; spindle assembly; strength stiffness check
