On the failure of modern CNC machine tools

Modern CNC machine malfunction causes of many , by their nature discouraged , notices can be divided into fragmented and random interdiction ; diagnostic and non- diagnostic performance flash obstruction ; destructive and non -destructive fault ; flow quality character fault ; obstruction , such as hardware and software .

Due to the single category of CNC machine tools , CNC machine tools on the site to discourage the occurrence of pedicle foundation in :

1 , a small portion of the machine overcast obstacle . Such as feed drive chain obstacles blocking spindle components , ATP failure, and other matching accessories discouraged .

2, the electrical machine locally on the body and strong electric control local obstruction. As mobile hardware overtravel axis overcast hinder , impede the magazine can not find the knife , spindle , regardless of the degree of dissuasion, tools, fixtures holding overcast barriers, various motor does not work to discourage , creamy device failure.

3 , feed servo crushing hinder indoor lifting machine . Such as servo feed trivial slip , slip detection , overheat alarm, high current, high voltage, low voltage , overload , disconnection response rate , switching action alarm concern , machine control , vibration , noise overshoot is too large , cylindrical tolerance obstruction and so on.

4 , the spindle servo trivial fault . If the spindle electromechanical vibration , mechanical and electrical type implement noise, speed or over the exceptionally large value of ills , electrical overheating, excessive current , Enron blown regeneration circuit failure .

5 , NC crushing overcast hinder . 手轮见效阻挠等。">If no CRT luminance , no picture , NOTREADY emerge , PROGRAMSTOP performance , MDI effective , HOME is not normal , and so frustrate effective electric hand wheel .
