Its technical scheme is such, and it comprises lathe bed, and said lathe bed both ends are equipped with main spindle box and tailstock respectively; It is top to be axially installed with the location on the said tailstock; On the said lathe bed planker is installed, on the said planker knife rest is installed, it is characterized in that: it also comprises stationary center and centering disc; Said centering disc is through the spindle nose of bolted in said main spindle box; Said stationary center and said centering disc are through the coaxial close-fitting of Morse's taper, and said location is top to be coaxially installed on said tailstock through pneumatic means, said main shaft, centering disc, stationary center and locate top coaxial installation.

It is further characterized in that:

Said pneumatic means comprises piston type cylinder, and said location is top axially to be installed on said tailstock through said piston type cylinder, and piston rod end top and said piston type cylinder, said location is coupling;

Encorbelment on the said main spindle box connection pressing plate is installed; Said connection pressing plate and said main shaft axially parallel and encorbelment and be installed on the top of said stationary center; The end of encorbelmenting of said connection pressing plate is set to the fork-shaped opening; Said fork-shaped opening is vertically installed with bolt, and said bolt bottom is equipped with the workpiece location bearing, leaves 0.2mm～0.3mm gap between said workpiece location bearing bottom surface and the said stationary center outer wall.

Its further characteristic also is:

Said knife rest is provided with two, and said two knife rests are installed on the vertical two ends of said planker near a side of said main spindle box respectively, on the knife rest of wherein said vertical upper end outer dise knife are installed, and on the knife rest of said vertical lower end rose reamer are installed.

Adopt numerically controlled lathe structure of the present invention to come the aluminium base-photoconductor drum of turning processing; Its beneficial effect is: it is top with the location to be separately installed with coaxial stationary center on its main spindle box and the tailstock; The stationary center that wherein is installed on main spindle box is connected with the coaxial close-fitting of centering disc through Morse's taper; Centering disc is again through interior coaxial connection of main shaft of bolt and main spindle box, thus guaranteed stationary center to the accurate centering of workpiece, improved positioning accuracy, and be installed on the top pneumatic means that is connected with in location on the tailstock; Automatically workpiece is clamped through pneumatic means promotion location is top; It can not only reduce the low problem of clamping positioning accuracy of the manual clamping existence of workpiece in the past, and can improve clamping workpiece efficient greatly, and raises labour productivity; And in the location top above, encorbelmenting on the main spindle box is equipped with the end and is the ringent connection pressing plate of fork-shaped; Its fork-shaped open end vertically is connected with bolt; The bolt bottom is equipped with the workpiece location bearing; Through the workpiece location bearing workpiece end is positioned, further guaranteed the accuracy of workpiece location, improve the workpiece crudy; In addition; Be separately installed with knife rest at planker near vertical two ends of main spindle box one side, be separately installed with outer dise knife and rose reamer on two knife rests, turning adds and drives the rose reamer inverted running and can accomplish workpiece is added turning when accomplishing excircle of workpiece turning rear base plate man-hour; Planker once moves back and forth cylindrical and the chamfer machining that can accomplish workpiece; It has not only removed the frequent change of cutter from, and can significantly reduce lathe running time back and forth, and clamping of workpiece just can be accomplished cylindrical turning and chamfering turning; Reduce the problem of the second positioning error that the replacing because of cutter in the turning process also brings, further guaranteed the crudy of product.
