The combined machine tool has the advantages of low cost and high efficiency, is widely used in mass production and mass production, and can be used to form an Automatic Production Line.
Combination machine is based on common parts, together with the specific shape of the workpiece and processing technology designed by the special components and fixtures, composed of semi-automatic or Automatic Machine.
It is generally multi-axis, multi-knife, multi-process, multi-faceted or multi-station at the same time processing, production efficiency several times higher than the universal machine to several times. As the common parts have been standardized and serialized, can be flexibly configured as needed, which can shorten the design and manufacturing cycle.
Combination machine tools are generally used for processing box type or extraordinary shape of the parts. During machining, the workpiece is generally not rotated, the drilling tool, reaming, counterbore, reaming, boring, milling plane, internal and external thread cutting and machining of the external circle are realized by the rotary motion of the tool and the relative feed movement of the tool and the workpiece And face and so on.
Some combination machine a workpiece using the turning head clamp to be rotated by the feeding movement for the tool can also be realized rotating parts for certain (e.g., flywheel, rear axle half shaft, etc.) and the outer face machining.
Special machine tools are developed with the rise of the automotive industry. In the special machine parts due to repeated use, and gradually developed into a common component, resulting in a combination of machine tools.
In order to make the combination machine tool can be used in small and medium-sized batch production, often need to apply group technology, the structure and process similar parts concentrated in a combination of machine processing, in order to improve machine utilization.
There are two common types of machines of this type, which are interchangeable headstock box-type machines and turret-type machine tools.
