导轨丝杠出现故障问题都是很常见的问题，但也是可以避免的，关键是要看导轨的保养工作，有时还必须考虑到导轨的组成元件，例如保持架的材质、形式印设计与工艺因素，也与导轨内部的滑动摩擦，润滑剂的贮存与维持，滚动体运转的稳定性等息息相关。

The failure of the guide rail lead screw is a common problem, but it can also be avoided. The key is to see the maintenance of the guide rail. Sometimes, it is also necessary to consider the components of the guide rail, such as the material of the cage, the design of the form print and the process factors, and it is also closely related to the sliding friction inside the guide rail, the storage and maintenance of the lubricant, and the stability of the rolling element operation.

1、电动机过热报警的修补

1. Repair of motor overheat alarm

缺陷现象：X轴电动机过热报警剖析及处理进程：电动机过热报警，发生的原因有多种，除伺服单元本身的问题外，或许是切削参数不合理，亦或许是传动链上有问题。而该机床的缺陷原因是由于直线导轨镶条与导轨空位太小，调得太紧。松开镶条防松螺钉，调整镶条螺栓，使运动部件运动活络，确保0.03mm的塞尺不得塞入，然后锁紧防松螺钉。缺陷清扫。

Defect phenomenon: X-axis motor overheat alarm analysis and processing process: The motor overheat alarm occurs for a variety of reasons. In addition to the problem of the servo unit itself, it may be that the cutting parameters are unreasonable, or there may be a problem on the transmission chain. The reason for the defect of the machine tool is that the gap between the linear guide rail insert and the guide rail is too small and too tight. Loosen the insert lock screw, adjust the insert bolt, make the moving parts move flexibly, ensure that the 0.03mm feeler gauge cannot be inserted, and then lock the lock screw. Defect cleaning.

2、行程终端发生显着的机械振动缺陷修补

2. Repair of significant mechanical vibration defects at the end of travel

缺陷现象：某加工作业时，作业台X轴方向位移挨近行程终端进程中发生显着的机械振动缺陷，缺陷发生时体系不报警。

Defect phenomenon: during the operation of a machining center, the X-axis displacement of the worktable is close to the end of the stroke, and a significant mechanical vibration defect occurs. When the defect occurs, the system will not alarm.

剖析及处理进程：因缺陷发生时体系不报警，但缺陷显着，故经过交换法查看，供认缺陷部位应在X轴伺服电动机与丝杠传动链一侧。为差异电动机缺陷，可折卸电动机与滚珠丝杠之间的弹性联轴器，独自通电查看电动机。

Analysis and processing process: because the system does not alarm when the defect occurs, but the defect is significant, so through the exchange method, the admitted defect position should be at the side of the X-axis servo motor and the lead screw drive chain. In order to distinguish the defects of the motor, the elastic coupling between the motor and the ball screw can be removed, and the motor can be checked by powering on alone.

查看结果表明，电动机作业时无振动现象，显着缺陷部位在机械传动部分。脱开弹性联轴器，用扳手翻滚滚珠丝杠进行手感查看;经过手感查看，发现作业台X轴方向位移挨近行程终端时，感觉到阻力显着增加。拆下作业台查看，发现滚珠丝杠与导轨不平行，故而引起机械翻滚进程中的振动现象。经过细心修补、调整后，从头装好，缺陷清扫。

The inspection results show that there is no vibration during the operation of the motor, and the obvious defect is in the mechanical transmission part. Disengage the elastic coupling and roll the ball screw with a wrench to check the handle; Through hand feeling inspection, it is found that the resistance increases significantly when the displacement of the X-axis direction of the workbench approaches the end of the stroke. Dismantle the worktable and check it. It is found that the ball screw is not parallel to the guide rail, which causes vibration in the process of mechanical rolling. After careful repair and adjustment, install from the beginning and clean the defects.

3、滚珠丝杠螺母松动引起的缺陷修补

3. Defect repair caused by loose ball screw nut

缺陷现象：机床Z轴作业(方滑枕为Z轴)哆嗦，瞬间即呈现123号报警;机床间断作业。剖析及处理进程：呈现123号报警的原因是盯梢过失超出了机床数TEN345/N346中所规则的值导致此种现象有三个或许：

Defect phenomenon: the machine tool Z axis operation (the square ram is Z axis) trembles, and the 123 alarm will appear immediately; The machine tool operates intermittently. Analysis and processing process: The reason for the 123 alarm is that the tracking error exceeds the value specified in the machine tool number TEN345/N346, which leads to three possible reasons:

①方位测量体系的检测器材与机械位移部分联接不良。

① The detection equipment of the azimuth measurement system is not well connected with the mechanical displacement part.

②传动部分呈现空位。

② The transmission part is empty.

③方位闭环放大系数KV不匹配。

③ The azimuth closed-loop amplification factor KV does not match.

注意，使用前后要细心擦净导轨和丝杠表面的油污，特别是沟槽里的油污，要注意导轨安装孔内的油污。用油脂枪嘴在注油油嘴往传动腔内部加油，直内部污油全部被挤出。被挤出的污油。更多相关内容就来我们网站http://www.jngongrun.com咨询吧！

Attention: before and after use, carefully clean the oil stain on the guide rail and the lead screw surface, especially the oil stain in the groove, and pay attention to the oil stain in the guide rail installation hole. Use the grease gun nozzle to add oil to the inside of the transmission cavity at the oil nozzle until all the dirty oil inside is squeezed out. Remove the squeezed dirty oil.
