Servo system is an important part of CNC machine tools and is used to realize feed servo control and spindle servo control of CNC machine tools. The function of the servo system is to convert the command information received from the numerical control device into the linear displacement or angular displacement of the machine tool execution part after power amplification and shaping. Since the servo system is the last link of the CNC machine tool, its performance will directly affect the technical indicators such as the precision and speed of the CNC machine tool. Therefore, the servo drive device of the CNC machine tool is required to have good rapid response performance and accurately and sensitively track the CNC device. The digital command signal sent out, and can faithfully execute the command from the numerical control device, improve the system's dynamic following characteristics and static tracking accuracy.
Servo tizim ikkita qismni o'z ichiga oladi: qo'zg'alish moslamasi va aktuator. Haydash moslamasi shpindelli qo'zg'aluvchi blokdan, oziqlantiruvchi vositadan, shpindelli servo dvigateldan va besleme servo dvigatelidan iborat. Step motorlar, DC servo motorlar va AC servo motorlar tez-tez ishlatiladigan drayvlardir.
O'lchov elementi CNC dastgohining har bir koordinata o'qining haqiqiy siljish qiymatini aniqlaydi va uni qayta aloqa tizimi orqali dastgoh asbobining CNC qurilmasiga kiritadi. CNC qurilmasi berilgan qiymatni buyruq qiymati bilan taqqoslaydi va o'rnatilgan qiymatni servo tizimga chiqaradi. Kerakli o'zgartirish buyrug'i.
