- |Single-spindle vertical lathe

Irregular moulded parts are machined by the reliable V series with maximum operational and process reliability.
The single-spindle vertical lathes are characterised by a solid construction with polished flat guideways, a large revolver and extremely powerful spindle bearings.
This reduces the effects of thermal deformation and vibration.
The Okuma V series brings together single-spindle vertical lathes with a box-type base and column, designed for turning large-diameter parts. The range includes the V40R and V100R models, which cover different production needs while sharing the same robust column-type construction. Moving from the entry model to the higher-capacity model, the series allows increasingly larger workpieces to be machined, giving users the flexibility to choose the size best suited to their production cycle. All models share Okuma's build reliability and expertise in vertical turning, ensuring precision and consistent performance over time. The box-type base and column structure ensures rigidity and stability during chip removal, making the V series a versatile solution for machining large-diameter components across various industrial sectors.
