Compared with the traditional lathe, CNC lathe structure has the following characteristics:

    1 due to the two directions of movement of the CNC lathe turret is driven by two servo motors, so it's a short drive chain. Hanging round, light bars and other transmission components do not have to use links directly with the screw, servo motor driven turret movement. The servo motor screw can also be used synchronous belt vice or gear pair links.

    2 multi-function CNC lathe is a DC or AC spindle control unit to drive the spindle continuously variable control instructions do not have to use a multi-stage gear pair between the spindle variable speed. Extended range, generally but also through a gear pair to achieve sub stepless speed regulation, even so, bedside cabinet structure is much simpler than conventional lathe. The CNC Lathe another structure is characterized by stiffness, this is in order to match with high-precision control of the control system, in order to adapt to high-precision machining.

    3. CNC lathe structure is characterized by the light drag. Turret move generally use the ball screw. The ball screw is the key to one of the mechanical parts CNC lathe, ball screw installed at both ends of the rolling bearing is dedicated uranium bearing, the pressure angle is much greater than commonly Order of the angular contact ball units. Bearings paired installation is optional, the best bearing factory is paired.

    In order to drag the lightweight, CNC lathe lubrication is full, mostly oil mist lubrication.

    Due to higher prices of CNC machine tools, control system longer, so the the CNC lathe sliding rail also requires good wear resistance. CNC lathes commonly used the inlaid steel rail, long time to maintain the accuracy of this machine, its life may be extended by many.

    6 CNC lathe also has sufficient processing cooling, more rigorous protection, automatic operation generally in the fully closed or semi-closed state.

    The CNC lathes general comes with automatic chip device.
