Vanguard Machine Tools > Conventional Vertical Lathes >
Double-Column Vertical Turret Lathes

These conventional, double column vertical lathes are suitable for machining faces, internal and external cylindrical surfaces, inner holes, and the internal and external circular cones of many types of medium to large sized work pieces. They can also be used for boring and enlarging holes.

The high accuracy and load capacity of these machines is achieved by using high quality cast parts for the major structural components, high accuracy bearings for the spindle, and precision sliding surfaces. The gear box uses hardened and ground gears for low noise and high accuracy. The slide mating surfaces are PTFE coated for low friction and increased wear resistance. Lubrication of the guide ways is from a central lubrication system. All hydraulic and electrical parts are sourced from internationally known companies.

Electrical control is by PLC for high reliability. These machines can be outfitted with DROs for the two rail heads. The machines have been designed and built to provide highly accurate machining while maintaining ease of operation and maintenance over a long service life.
