eduardajdini Апр. 12

Heavy-duty lathe, the machine tool with the weight of 10 ~ 30 tons belongs to large machine tool, 30 ~ 100 tons belong to heavy machine tool, and more than 100 tons belongs to super heavy machine tool. Heavy machine tools refer to the metal cutting machine tools listed in the catalog of large machine tools.


CNC machine tool is a mechatronics product that integrates mechanical, electrical, hydraulic, pneumatic, microelectronics and information technology. It is a machine tool with the advantages of high precision, high efficiency, high automation and high flexibility in mechanical manufacturing equipment. It has a wide range of processing performance, can process CNC turned parts such as straight cylinders, oblique cylinders, arcs, and various threads. It has various compensation functions of linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts.


Heavy-duty CNC lathe is divided into large-scale CNC vertical lathe and large-scale CNC horizontal lathe. Turning the rotating workpiece with a turning tool can automatically complete the processing of cylindrical surface, conical surface, spherical surface and thread, and can also process some complex rotary surface and curved surface. Large CNC lathe is mainly used for processing large and extra-large parts. It is used for national defense and military industry, aerospace, shipbuilding, energy (thermal power, hydropower, nuclear power, wind power), transportation (railway, automobile), metallurgy, engineering machinery and other major industrial pillar industries as well as national key engineering projects.


There are two trends in the development of heavy machine tools. On the one hand, machining center or large flexible machining unit and large combined compound machining machine are the development direction, among which horizontal boring and milling machine will be gradually replaced by high-speed machining center and flexible machining unit; floor type milling and boring machine is mainly to develop large combined compound machining center, that is, two or more main machines will be combined into compound machining machine to adapt to large machining Because of the characteristics of small batch production, complex process, long auxiliary time and processing cycle, it is often difficult to complete all the processing procedures by one machine tool, but it can be completely realized by two combined machining centers. For example: two CNC gantry boring and milling machines form a composite machining center, and share the bed and guide rail, respectively with a rectangular worktable and a rotary worktable (indexing), which can carry out boring and milling; a floor type milling and boring machine and a CNC single column vertical lathe form a large composite machining center, which share the bed guide rail, with a floor platform and a rotary table, which can complete turning and boring , milling, drilling and other processing, rotary table can be divided. There are also two large floor milling and boring machines sharing bed guide rail and other combination forms. In this way, the floor area is saved, the cost is reduced, and the processing efficiency is improved. Another development trend is to pursue fine manufacturing, improve the process content of equipment manufacturing, and embody the characteristics of safety, environmental protection and humanization of machine tools.
