The Tongtai VP Series of heavy duty vertical machining centers is engineered for high-speed mass production.
X, Y, and Z axis travels are 32.3″ x 20″ x 20.1″ (820 mm x 508 mm x 510 mm) for the VP-8 machine, and 40.2″ x 20.1″ x 23.6″ (1021 mm x 510 mm x 600 mm) for the larger VP-10. Heavy Meehanite FC-30 castings provide rigidity and the machines’ triangulated design provides a rigid and stable machining platform.
