外圆磨床、端面外圆磨床、曲轴磨床等加工轴类零件的磨床,在机床结构、加工方法上比较相近,本文统称为外圆类磨床。在数控系统的应用方法上,这些磨床也有相似之处。在加工过程中,砂轮和工件之间的相对运动,主要是砂轮沿工件轴向和径向的运动。前者一般由工作台的运动实现,在数控磨床 Cylindrical grinding machines, face cylindrical grinding machines, grinding machines and other crankshaft shaft grinding machine parts, in the machine structure, processing methods are relatively similar, this article collectively referred to as cylindrical grinding machines. In the numerical control system application method, these grinders also has the similarities. In the process of machining, the relative movement between the grinding wheel and the workpiece is mainly the movement of the grinding wheel along the axial and radial direction of the workpiece. The former is generally achieved by the movement of the table in the CNC grinding machine
