Went deep into CNC machine tools

The functions of milling machines and double-headed lathes are very similar; both are used for the double-ended processing of round bar workpieces.

CNC lathes are one of the most widely used CNC machine tools. They are mainly used for the cutting processing of inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads of shaft-type or disk-type parts. They can also perform operations such as grooving, drilling, reaming, boring, and tapping. CNC machine tools automatically process workpieces according to pre-programmed processing procedures. We write the workpiece's processing route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool, record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool to control the machine tool to process the workpiece.

The functions of milling and tapping machines and double-head lathes are very similar; both perform double-ended processing of round bar workpieces. Milling and tapping machines mill surfaces, drill center holes, tap threads, and perform turning operations. Double-head lathes use a centrally driven spindle; because the spindle passes through the center, the coaxiality is better.

The range of applications for milling and tapping machines is far greater than that of double-head lathes; double-head lathes fall under the category of lathes. In terms of trends, if automation can be incorporated, the overall trend for double-head lathes is still very good.
