Technical advantages and future development trend of combined lathe

The earliest combination machine was made in the United States in 1911 for the machining of automotive parts. Initially, each machine tool manufacturer has its own common component standards. In order to improve the interchangeability of common parts of different manufacturers and facilitate user use and maintenance, in 1953, Ford Motor Company and General Motors and US machine tool manufacturers negotiated the principle of standardization of common parts of combined machine tools, that is, strict regulations The size of the contact between the components, but the structure of the components is not specified.


The future development of combined machine tools will use more speed-regulating motors and ball screws to simplify the structure and shorten the production cycle; use digital control system and spindle box, fixture automatic replacement system to improve process adjustability; Flexible manufacturing systems, etc.


Combination machine tools are generally used to machine parts of boxes or special shapes. During machining, the workpiece generally does not rotate. The rotary motion of the tool and the relative feed motion of the tool and the workpiece realize drilling, reaming, boring, reaming, boring, milling plane, cutting internal and external threads, and machining the outer circle. And end faces, etc. Some combination machine tools use a turning head to hold the workpiece to rotate, and the tool can be used for feeding motion, and also can realize the outer circle and end surface processing of some rotary body parts (such as flywheel, automobile rear axle half shaft, etc.).


The combined machine tool generally adopts multi-axis, multi-knife, multi-sequence, multi-face or multi-station simultaneous processing, and the production efficiency is several times to several tens of times higher than that of the general machine tool. Since the common components 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 and mass production, and can be used to form an automatic production line. Special machine tools have evolved with the rise of the automotive industry. In the special machine tool, some components are gradually developed into common parts due to repeated use, thus producing a combined machine tool.


The future CNC combination machine tool will bring more choices and more impact to the field of metal cutting machine tools.
