introduction： After loading and adjusting﹐Can automatically complete the work cycle according to certain procedures﹐A lathe that repeatedly processes a batch of workpieces。Lathes that can automatically complete the work cycle except for loading and unloading parts are called semi-automatic lathes。Automatic lathe can reduce the manual labor intensity of workers﹐Reduce auxiliary time﹐Multiple machine tools can be supervised by one person﹐Higher productivity。 By number of spindle﹐Automatic lathes are divided into single-axis and multi-axis two categories。The former mainly has a uniaxial longitudinal cutting﹑Single axis turret and single axis crosscut3Species type﹔The latter mainly has two kinds of sequential operation and parallel operation﹐And according to the configuration of the spindle there are vertical and horizontal points。Machine tools generally use cams and stops
