In a conventional CNC lathe, the workpiece is clamped in a chuck and rotates while a stationary tool moves toward it to cut material. When machining long, slender parts on a conventional lathe, the workpiece tends to "flex" or bend away from the tool due to the cutting pressure. This leads to tapered parts and poor surface finishes.
However, if you only make large parts (over 2” diameter) or heavy-removal roughing, a traditional CNC turning center from Mazak or Okuma might be a better fit. tsugami cnc
