Enquire Now
The You Ji YV and VTL Series of vertical ram-type turning lathes are built for large, heavy part machining. With tables ranging from 600mm to 4500mm diameter.
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.
The YV series machines are economical and suitable for most general-purpose applications. YV machines are available with 600 mm, 1000 mm, 1200 mm, and 1600 mm tables and feature infinite-position moveable cross rails (except YV-1000) as well as tool changers. Full contouring C axis with live milling is optional.
The VTL series machines are robust and suitable for demanding applications. VTL machines are available in table sizes from 1000 mm to 4500 mm and feature a symmetrical base/column design with moveable cross rails in programmable 200mm increments. Variable column heights/ram strokes are available to accommodate very tall workpieces.
Twin rams are available on the VTL-1600 size and larger machines. The VTL-3000 and larger machines are a double column design, and the optional C-axis features a dual spindle motor/dual pinion drive, providing nearly zero backlash and the most accurate C axis positioning and repeatability available.
