Ball screw is an ideal construction which can transform rotational motion into linear motion. The other components are very simple. Bearings, screw nuts and all three are integrated into one. Its manufacturing materials are generally stainless steel iron, or steel with low purity as the main component. Its manufacture is the same as that of linear guideway. It can not be used to show the mechanical damage caused by clamping, falling, or excessive friction.

从运用的范围上，滚珠丝杆与直线导轨的基本相同，都是运用在大型的机床更或是一些精细的仪器上拥有广泛的运用。

From the scope of application, ball screw and linear guide are basically the same, are used in large machine tools or some fine instruments have a wide range of applications.

直线导轨在大型机床上的运用大多是带动机床运动，而且在某些特定的环节上需要做到可以作为支撑点着力点，而滚珠丝杆所做的就是让机床的某些部件做到往复运动。

Linear guides are mostly used in large machine tools to drive the movement of the machine, and in some specific links need to be able to act as a support point, and what the ball screw does is to make some parts of the machine to achieve reciprocating motion.

不要小瞧这种往复运动，许多机械的循环出产假如没有它，将很难进行，而且想要做到自动化几乎成为了不可能，都需要人工推力，或是特定的某些辅助的装置来辅助出产，假如是这样那么数控机床的产值将大幅度下滑，盈利天然更不用说了。

Don't underestimate this reciprocating motion. If there is no reciprocating motion, it will be very difficult to produce many machines. Moreover, it is almost impossible to achieve automation. Manual thrust or some specific auxiliary devices are needed to assist the production. If so, the output value of CNC machine tools will decline dramatically, not to mention the profits.

机器零件老化，呈现毛病是一件再平常不过的事情了，就连较精细的滚珠丝杠也不破例。滚珠丝杠在日常运用中呈现的毛病是千变万化的，每次都不相同，所以没有固定的修补办法。

It is common for machine parts to aging and show defects, even the most sophisticated ball screw is not exceptional. Ball screw in daily use presents a variety of defects, each time is different, so there is no fixed repair method.

有些毛病可能是小毛病，也有可能是渐发性毛病，一开始不会引起留意，但是跟着零件的不断老化，运用的时间的慢慢加长，慢慢地毛病会越来越严重。所以，只有正确的判别出毛病的原因才能准确的修补。

Some faults may be minor or gradual. They won't be noticed at first. However, with the aging of parts, the use of time will be slowly lengthened and the faults will become more and more serious. Therefore, only by correctly identifying the cause of the defect can it be correctly repaired.

1.假如在运用中机床发生较大的噪音并伴跟着不断轰动，仔细查看传动部分没有问题后，应该考虑到是不是因为润滑剂不良的问题导致的。

1. If there is a big noise in the machine tool in operation and it is accompanied by a constant sensation, after carefully examining the transmission part, we should first consider whether it is caused by the bad lubricant problem.

由于工作量较大，机器运用时间较长，丝杆螺母的自动润滑体系就会阻塞，不能润滑，这时在轴承和螺母中参加润滑剂就可以解决了。

Because of the heavy workload and the long working time of the machine, the automatic lubrication system of the screw and nut will be blocked and can not be lubricated. At this time, the lubricant can be added to the bearing and nut to solve the problem.

2.假如机床在工作中轰动并不断匍匐，这时应该考虑查看伺服电机驱动，可能是因为伺服电机驱动增益参数不符导致的，只需调节合适了，就会轰动匍匐的情况了。

2. If the machine tool is stirring and crawling constantly in the work, we should consider looking at the servo motor drive at this time. It may be caused by the inconsistency of the servo motor drive gain parameters. Only by adjusting properly, the situation of stirring and crawling will be eliminated.

在日常运用中只需呈现不正常的声响或者是行为，这就是机器为咱们传递的信号，咱们要及时检测，找的问题的根源好准确的维修，保持机器正常工作。

In daily use, we only need to present abnormal sound or behavior. This is the signal that the machine transmits to us. We need to detect in time, find the root of the problem and maintain the machine working properly.
