In metalworking, any rotating part that can be clamped on a conventional lathe can be machined on a CNC lathe. However, CNC lathes offer advantages such as high machining accuracy, the ability to perform linear and circular interpolation, and automatic speed changes during machining, resulting in a much wider processing range than conventional machine tools.
CNC lathes possess high rigidity, manufacturing and tool setting precision, and can easily and accurately incorporate manual and automatic compensation, enabling the machining of parts with high dimensional accuracy requirements. Furthermore, the tool movement in CNC turning is achieved through high-precision interpolation and servo drives. Combined with the machine tool's high rigidity and manufacturing precision, it can machine parts with high requirements for shape accuracy, such as straightness, roundness, and cylindricity. For arcs and other curved contours, the machined shape closely approximates the geometry required on the drawing compared to using a copying lathe.
CNC lathes have a constant surface speed cutting function, allowing the selection of the optimal surface speed for cutting conical surfaces and end faces, resulting in a small and consistent surface roughness value, producing parts with a small and uniform surface roughness. CNC lathes can not only machine straight, tapered, and face threads of any constant lead, but also threads with smooth transitions between different leads. Unlike conventional lathes, CNC lathes do not require alternating spindle rotation during thread cutting; they can continuously cycle through the threads until completion, resulting in high thread cutting efficiency.
