The assembled machine tool is the centralized working procedure and high efficiency machine tool, which posed by the massive general parts and the few special parts, it can process one kind (or many kinds)of part on the multi-knives, multiple-spindle, multi- surface, multi-locations. Its manufacture cycle is short, the investment is little ,but the economic benefit is high .
