Fixed Headstock Type CNC Automatic Lathe.
Although the machine is simply configured with two spindles and one turret, it is capable of superimposition machining through synchronization control between axis control groups because an X-axis has been added to the back spindle. Chucks of the same diameter at the front and back allow a greater range of workpieces to be handled. In addition, the Ø65-mm front spindle specifications in the lineup make robust cutting with a powerful spindle motor a reality. The slideways incorporate LFV (low-frequency vibration cutting) technology, eliminating trouble created by swarf nesting. This helps to achieve stable production.
