The You Ji YV and VTL Series of vertical ram-type turning lathes are built for large, heavy part machining. Starting with the 24″ (609 mm) table VTL-800 machines and ending with the 177″ (4495 mm) table VTL-4500 units, the 29 machines in the series offer a wide variety of size and configurations for productive processing of medium to large size parts.
The vertical lathes feature heavy Meehanite cast iron construction, rigid, extra large box ways, and large diameter pre-tensioned ballscrews. All mating surfaces are coated with Turcite-B and then hand scraped for perfect fit and alignment. Both the YV and VTL series machines feature Timken Cross Roller table bearings for best rigidity and precision. High power spindle motors coupled with ZF planetary gearboxes provide high torque for heavy metal removal.
