導軌絲杠出現故障問題都是很常見的問題，但也是可以避免的，關鍵是要看導軌的保養工作，有時還建議考慮到導軌的組成元件，例如保持架的材質、形式印設計與工藝因素，也與導軌內部的滑動摩擦，潤滑劑的貯存與維持，滾動體運轉的穩定性等息息相關。

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、電動機過熱報警的修補

1. Repair of motor overheat alarm

缺陷現象：X軸電動機過熱報警剖析及處理進程：電動機過熱報警，發生的原因有多種，除伺服單元本身的問題外，或許是切削參數不合理，亦或許是傳動鏈上有問題。而該機床的缺陷原因是由于直線導軌鑲條與導軌空位太小，調得太緊。松開鑲條防松螺釘，調整鑲條螺栓，使運動部件運動活絡，確保0.03mm的塞尺不得塞入，然后鎖緊防松螺釘。缺陷清掃。

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、行程終端發生顯著的機械振動缺陷修補

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

缺陷現象：某加工作業時，作業臺X軸方向位移挨近行程終端進程中發生顯著的機械振動缺陷，缺陷發生時體系不報警。

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.

剖析及處理進程：因缺陷發生時體系不報警，但缺陷顯著，故經過交換法查看，供認缺陷部位應在X軸伺服電動機與絲杠傳動鏈一側。為差異電動機缺陷，可折卸電動機與滾珠絲杠之間的彈性聯軸器，獨自通電查看電動機。

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.

查看結果表明，電動機作業時無振動現象，顯著缺陷部位在機械傳動部分。脫開彈性聯軸器，用扳手翻滾滾珠絲杠進行手感查看;經過手感查看，發現作業臺X軸方向位移挨近行程終端時，感覺到阻力顯著增加。拆下作業臺查看，發現滾珠絲杠與導軌不平行，故而引起機械翻滾進程中的振動現象。經過細心修補、調整后，從頭裝好，缺陷清掃。

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、滾珠絲杠螺母松動引起的缺陷修補

3. Defect repair caused by loose ball screw nut

缺陷現象：機床Z軸作業(方滑枕為Z軸)哆嗦，瞬間即呈現123號報警;機床間斷作業。剖析及處理進程：呈現123號報警的原因是盯梢過失超出了機床數TEN345/N346中所規則的值導致此種現象有三個或許：

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方位測量體系的檢測器材與機械位移部分聯接不良。

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

②傳動部分呈現空位。

② The transmission part is empty.

③方位閉環放大系數KV不匹配。

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

注意，使用前后要細心擦凈導軌和絲杠表面的油污，非常是溝槽里的油污，要注意導軌安裝孔內的油污。用油脂槍嘴在注油油嘴往傳動腔內部加油，直至內部污油全部被擠出。清除被擠出的污油。更多相關內容就來我們網站http://www.2b4g.com咨詢吧！

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.
