VTL Series

(Model Variants: VTL 500-5/7, VTL 750)

To meet the requirement of heavy engineering industries such as Oil & Gas, Earth Moving, Automobile VTL series machines delivers its best. Graded cast iron bed and column assures thermal stability and better machine life accuracy along with great rigidity, stability and performance. Box type construction, heavy duty spindle, high speed bi-directional servo turret and wider box guide ways assures vibration free cutting. VTL finds its wide application for machining of bigger diameter heavy component like valve body, motor body, break drum, disc brake etc.
