Features

Ease of loading and unloading for irregular-shape and heavy work-piece.
Excellent surface contact between work-piece and chuck to ensure high precision machining.
Decreased gravitational and centrifugal forces eliminate run-out during cutting to achieve optimum roundness.
It is the best design for easy operation and reduces investment risk.
The VTL series of vertical turning lathes are designed especially for high precision, high rigidity, high stability, under super heavy cutting conditions including non-symmetric work-pieces.
