Most MMT machining operations are performed on turning centers. A typical turning center simply replaces the standard turret tool post on a CNC lathe with a powered tool post, adding a C-axis function to the spindle.
Due to limitations in the structure and dimensions of the turret tool post, the power head has low power and rotational speed, and cannot accommodate large tools. Such turning centers are primarily for turning, with milling and drilling functions used only as auxiliary operations.
Powered tool posts are expensive, resulting in high costs for turning centers that are generally unaffordable for most users. Economical MMT machining centers mostly use XZC axes, which essentially add a rotating C-axis to the chuck to achieve basic milling functions.
