Automatic lathes are divided into two categories: single-axis and multi-axis

      According to the number of spindles, automatic lathes are divided into two categories: single-axis and multi-axis. The former mainly has three types: single-axis longitudinal cutting, single-axis turret and single-axis cross-cutting; the latter mainly includes two types of sequential operation and parallel operation, and according to the configuration of the spindle, there are vertical and horizontal types. .

      Machine tools generally use cams and stops to automatically control the movement of the tool post, headstock and other auxiliary movements. The single-axis slitting automatic lathe uses cold drawn bars as blanks. In addition to rotating, it also feeds longitudinally with the spindle box, and the tool post performs transverse cutting and feeding to obtain higher machining accuracy.

      The machine tool is also equipped with accessories for drilling, reaming (see reaming) and thread cutting, and is an important machining equipment for the instrument industry. The single-axis turret automatic lathe has a turret tool post and multiple transverse tool posts, which can be cut in sequence with a variety of tools, and is suitable for processing small workpieces with complex shapes.

      The spindle box and the tool post of the single-axis transverse cutting automatic lathe do not make longitudinal feed movement, but the cutting process is completed by the transverse feed movement of the forming tool. This kind of machine tool is only used for processing simple shape, small size pin and shaft workpiece.

      Multiple spindles (usually 4, 6, 8) of a multi-axis automatic lathe are installed in a spindle drum that can be indexed periodically, and the blanks clamped in the spindle pass through each station to complete different processes. And cut off or unload at the last station.

      This lathe is suitable for processing workpieces with more complex shapes. The parallel operation multi-axis automatic lathe has several fixed position (usually 2 or 4) spindles, and the same process is processed at several stations at the same time, which is suitable for processing simple workpieces.
