一、综述内圆磨削工艺性比其他磨削差,其磨削系统动静刚性低,冷却和测量较困难,砂轮线速度不易提高,砂轮磨损快,循环动作又复杂。因此,新技术应用和产品更新换代比其他磨床缓慢。但是,自七十年代初,世界各国内圆磨床制造厂都努力研制模块化、电子化、一机多能、适应控制和数字控制内圆磨床。七十年代末到八十年代初期,内圆磨床已进入电子计算机数控(CNC)时代, First, a summary of the internal grinding technology than other grinding poor, the grinding system static and dynamic rigidity is low, cooling and measuring more difficult, the wheel speed is not easy to improve, wear fast wheel, the cycle of action is complicated. As a result, new technology applications and product updates are slower than other grinders. However, since the early 1970s, all of the world’s internal grinder manufacturers have struggled to develop modular, electronic, multi-function machines, adaptive control and digital control of internal grinder. The late seventies to early eighties, internal grinder has entered the era of computer numerical control (CNC)
