Horizontal Turning Centers
CNC Lathe – Nakamura Tome Lineup
Machines Available in Pacific NortWest – USA
Horizontal Turning Centers are the most widely recognized. Vertical turning centers are regularly called a vertical turret lathe or VTL. With a horizontal turning center, the spindle is horizontally oriented, and tools are mounted out of the side of tool holder and cut across the work-piece
