The combined machine tool is a semi-automatic or automatic special machine tool based on general components, together with special parts and fixtures designed according to the specific shape and processing technology of the workpiece.
It generally uses multi-axis, multi-knife, multi-process, multi-face or multi-position processing methods at the same time, and the production efficiency is several times to several dozen times higher than that of general-purpose machine tools. Since the general parts have been standardized and serialized, they can be flexibly configured as needed, shortening the design and manufacturing cycle.
Therefore, the combined machine tool has the advantages of low cost and high efficiency, and is widely used in mass production and mass production, and can be used to form an automatic production line.
Combined machine tools are generally used for machining box or extraordinary shaped parts. During processing, the workpiece generally does not rotate, and the drilling, reaming, boring, reaming, boring, milling, cutting, internal and external threading, and machining the external circle are performed by the rotary motion of the tool and the relative feed motion of the tool and the workpiece. And face and so on.
Some combined machine tools use a turning head to hold the workpiece and make it rotate. The tool can perform feed motion, and can also realize the machining of the outer circle and the end surface of certain rotary body parts (such as flywheel, axle of automobile rear axle, etc.).
Special machine tools developed with the rise of the automotive industry. In the special machine tool, some parts are gradually developed into general parts due to repeated use, resulting in a combined machine tool.
In order to make the combined machine tool able to be used in small and medium batch production, it is often necessary to apply group technology to concentrate the parts with similar structures and processes on one combined machine tool to improve the utilization of the machine tool.
There are two common types of such machine tools, which can be interchangeable spindle box type machine tools and turret type combination machine tools.
