Lathes

TNK800 / 940 -CNC Lathe Machine

Category: CNC Lathe

TNK800 / 940-CNC series are parallel CNC lathes of popular edition. They are suitable for turning of complicated shaft, sleeve, and disk type work-pieces such as turning of internal and external cylindrical, conical, arc surfaces and various threads.  And they are especially fit for turning of diversified work-pieces on small and medium batches. They are of high versatility, high efficiency, low inferiority and good conformability, Also, being excellent medium type machining equipment, they are of simple programming, easy operation and with full functions.

  1. The spindle can accomplish 4-stage infinite frequency variable speed changing. Being of wide range, big lap, full automatic, and the spindle speed can accommodate wide machining range.
  2. The spindle can accomplish large torque output at low speed range.
  3. The movable safe-guard design makes the machines easy to operate and easy to load/unload work-pieces.
  4. Equipped with load reducing device makes the tailstock easy to move.
  5. Taper turning unlimited angle and length.
  6. Cutting of various cylindrical and taper threads, and continuous transition threads.
