八、位置检测系统简介 数控机床对位置检测系统的基本要求是:高可靠性与抗干扰性,满足精度要求,成本低且便于维护。 位置检测系统中主要是检测元件。数控机床中常用的位置检测元件分回转型和直线型两大类。在回转型中包括脉冲编码器、旋转变压器、圆感应同变器及圆光栅或圆磁栅等。而直线型中包括直线感应同步器、计 Eight, the position detection system Introduction CNC machine tool position detection system for the basic requirements are: high reliability and anti-interference, to meet the accuracy requirements, low cost and easy to maintain. Position detection system is the main test components. CNC machine tools commonly used in the position detection device sub-return type and linear two categories. In the rotary type, including pulse encoder, resolver, inductors with circular induction and circular grating or circular magnetic grid and so on. The linear type includes a linear induction synchronizer, meter
