Spartan Precision Machinery now offers extended turning height models for its heavy-duty, Momentum MVL line of vertical turning lathes (VTLs). Momentum’s MVLs are offered in sizes from 63" to 98" swing, with optional milling capability. The product additions include “extended turning height" versions of the popular MVL-12 and MVL-12M and MVL-16 and MVL-16M models. Appended with an “HS” model designation, these machines offer significantly greater machining range. For example, the MVL-12HS has a 63" swing that allows for a 76" turning height. The MVL-16HS is a 78"-swing machine that provides a 94" turning height.
Standard features also include oversized rams and other major components; full-wrap, arc-shaped columns; heavy-duty rail elevation and locking components; floor-mounted toolchangers; twin-gear C-axis drives (on models with milling capacity); single-piece saddles; oversized, spiral-gear table drives; gear reduction on linear-axis motors; and thrust and radial table bearings. All models feature FANUC controls.
According to Spartan, these models provide advantages in horsepower, machine mass and maximum table load when compared with similarly-sized VTLs. All models are said to come with performance guarantees.
