本发明中公开的一种卧式加工机床具体工作过程如下：
首先工作台5通过配备的自动化工装夹具安装上待加工工件，外力驱动承托部13沿X轴导轨19滑动，使得B轴回转组件1沿X轴导轨19滑动靠近或远离A轴回转组件6，调整B轴回转组件1与A轴回转组件6的位置，然后驱动B轴转台11转动，B轴转台11驱动工件C轴箱体16绕B轴转动，C轴箱体上刀库面3随之转动，即刀库4随之转动，刀库4转动至与A轴回转组件6的主轴61相匹配的方向，然后沿Z轴方向调整立柱9的位置，沿Y轴方向调整滑鞍10的位置，将主轴61调节至与刀库4的刀具匹配的位置，主轴61转动将刀具取下，再次驱动B轴转台11和工件C轴箱体16转动，将工作台5转动至朝向主轴61的方向，调整立柱9和滑鞍10位置，同时调整B轴回转组件1的位置，使工作台5与主轴61位置对应，最后，C轴箱体16内的C轴动力组件驱动工作台5转动，工作台5驱动工件转动，主轴61上的刀具绕A轴转动对工件进行加工。
