Heavy duty lathes, machine tools with a self weight range of 10-30 tons belong to large-scale machine tools, 30-100 tons belong to heavy-duty machine tools, and over 100 tons belong to super heavy-duty machine tools. Heavy duty machine tools refer to metal cutting machine tools that have been included in the catalog of large machine tools.

Generally refers to machine tools with a weight of 10 tons or more and a single machine weight between 100-300kN. CNC machine tools are electromechanical integrated products that integrate multiple technologies such as mechanical, electrical, hydraulic, pneumatic, microelectronics, and information. It is a working mother machine in mechanical manufacturing equipment that has advantages such as high precision, high efficiency, high automation, and high flexibility. It has a wide range of processing properties and can process straight cylinders, oblique cylinders, arcs, and various types of threads. It has various compensation functions such as linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts
