机床床身

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。
