For major manufacturers, the major difficulty is the instrument monitoring and replacement of linear guide rail. Generally, the method we often try is to measure the AC and DC power supply voltage and relevant DC and pulse signals of each group with conventional electrical instruments. Through these troubleshooting, we can find the fault, such as monitoring the power supply with a universal meter, And the related signal status monitoring set on the circuit board, and observe the increase value of the related pulsation signal with an oscilloscope! When monitoring some function programs, the tried method is to program a function experiment program with functions such as G, m, s, t and f together, and store it on the corresponding medium. When fault diagnosis is needed, run this program to quickly determine the cause of the fault!

点:闲置时间较长的数控机床在投入使用前或对数控机床进行定期检修时。直线电机可以认为是旋转电机在结构方面的一种变形,它可以看作是一台旋转电机沿其径向剖开,然后拉平演变而成。近年来,随着自动控制技术和微型计算机的高速发展,对各类自动控制系统的定位精度提出了更高的要求,在这种情况下,传统的旋转电机再加上一套变换机构组成的直线运动驱动装置,已经远不能满足现代控制系统的要求,为此,近年来世界许多国家都在研究、发展和应用直线电机,使得直线电机的应用领域越来越广。

The first point: the CNC machine tool that has been idle for a long time shall be put into use or inspected regularly. Linear motor can be regarded as a structural deformation of rotating motor. It can be regarded as a rotating motor cut along its radial direction and then leveled. In recent years, with the rapid development of automatic control technology and microcomputer, higher requirements are put forward for the positioning accuracy of various automatic control systems. In this case, the traditional rotating motor combined with a set of linear motion driving device composed of transformation mechanism is far from meeting the requirements of modern control system. Therefore, many countries in the world are studying and With the development and application of linear motor, the application field of linear motor is becoming wider and wider.

第二点:机床加工造成废品而一时无法确定是编程操作不当、还是由于数控系统故障引起的。

The second point: it is impossible to determine whether it is due to improper programming operation or NC system failure.

第三点:数控系统出现随机性故障。一时难以区别是外来

The third point: random failure of CNC system. It's hard to distinguish at the moment. It's foreign

当然了虽然这些问题非常的烦人，但是又没有办法去避免，所以在平常的维护中就要非常的注意了~当然在选取配件的时候也要非常的注意，比如直线导轨、滚珠丝杆、直线轴承等

Of course, although these problems are very annoying, there is no way to avoid them, so we should pay great attention to them in normal maintenance ~ of course, we should also pay great attention to selecting accessories, such as linear guide rail, ball screw, linear bearing, etc
