要把长方形工件加工成两端尖角的形状 ,可把工件夹在立式仿形铣床的虎钳上 ,并在该铣床工作台上夹一曲面规或类似模板 ,划针及其磁性底座与机床的连接如图所示。加工时 ,定位铣刀在工件的起始点 ,划针指在模板曲面的相应位置 ,由划针沿着模板移动 ,从而带动铣头加工出需要的曲 The rectangular workpiece to be processed into sharp-edged shapes at both ends, the workpiece can be clamped in the vertical profile milling machine vise, and in the milling table clamp a surface gauge or similar template, the needle and its magnetic base and Machine connection as shown. Processing, the positioning cutter at the starting point of the workpiece, the needle refers to the corresponding position in the template surface, by the needle along the movement of the template, which drives the milling head to produce the required song
