CK84100 high performance CNC roll lathes are mainly used for semi-finishing and finishing turning of cast iron, steel and non-ferrous metal rolls. Using tools made of high-speed steel, carbide or other materials, they can turn and repair the outer circle, end face and various complex hole profiles and curved surfaces of the rolls. They can also be used to process shaft parts made of cast iron, steel and non-ferrous metals with the same size and weight range as the rolls. They can perform semi-finishing and finishing turning of the outer circle, end face and various complex curved surfaces.
Overall layout and composition of the machine:
This CNC auto
Roll Lathe adopts the layout of HT300 castings and horizontal lathes. It consists of functional components such as the bed, headstock, tailstock, slide, protective device, and electronic control system, as shown in the figure below:
Performance characteristics:
● The heavy
Cnc Roll Lathe has advanced and reliable structure, mature technology, good appearance, perfect and reliable safety protection device. Reasonable material selection, excellent manufacturing, excellent performance, long precision retention period, suitable for long-term, continuous, large load processing; The machine has good static, dynamic and thermal stiffness, stable and reliable operation control, simple operation interface, smooth, beautiful, easy maintenance.
● The main spindle bearings use high-precision double-row radial short cylindrical roller bearings with adjustable radial clearance, so the main spindle has strong rigidity, stable rotation and high precision. The above high stability and high rigidity structural design ensures the overall comprehensive processing accuracy of the machine tool.
● The CNC roll lathe is equipped with SIMENES828D CNC system, the main drive is driven by servo motor, and the longitudinal (Z axis) and transverse (X axis) are driven by ball screw. The longitudinal and transverse movement of the tool holder is driven by AC servo motor.
● The high performance CNC roll lathe is equipped with a set of centralized lubrication system and system link, just set the lubrication time and lubrication times, and fully automatic forced lubrication of each oil circuit component of the machine.
