CHA56 series vertical compound turning center is a universal machine, which is mainly used in the fully automatic machining and production of batch of discs and sleeve parts. It can not only machine brake plates and brake hubs, but also can process the turning and drilling of rotational and non-rotational parts, like pump shell, etc. This machine is equipped with good performance dual-channel NC system and adopts one regular and one inverted vertical spindle and the corresponding separate power turret respectively. It is able to achieve three-axis machining simultaneously from any three of X, Y, Z and C axis. A high reliability and automotive loading and unloading logistics mechanism is equipped on both sides of the machine, which enables the two-side machining process of turning, milling, boring, drilling and tapping after one time of clamping.
