一、主軸箱主軸制動機構失靈

1、 Spindle box spindle brake mechanism malfunction

1、制動電磁閥產生故障。采取措施：檢查電磁鐵YT6是否通電吸合，若不通電應檢查電氣線路；若電磁閥閥芯被卡住，應拆下清洗電磁閥，檢查閥芯是否被拉毛或閥孔有毛刺，若有需修光閥芯外圓和閥孔，必須使閥芯在閥孔內滑動靈活無阻滯現(xiàn)象；要求主軸制動時間約為3s。

1. The brake solenoid valve has malfunctioned. Measures taken: Check if the electromagnet YT6 is powered on and engaged, and if it is not powered on, check the electrical circuit; If the solenoid valve core is stuck, it should be removed and cleaned. Check if the valve core is roughened or if there are burrs in the valve hole. If there is a need to polish the outer circle of the valve core and the valve hole, it is necessary to make the valve core slide flexibly and without blockage in the valve hole; The spindle braking time is required to be approximately 3 seconds.

2、制動摩擦片產生磨損、表面太光滑、太薄或已經碎裂。采取措施：更換新的摩擦片，并調整使摩擦片之間留有適當間隙。

2. The brake friction plate is worn, the surface is too smooth, too thin, or has already broken. Measures taken: Replace the friction plates with new ones and adjust them to leave appropriate gaps between them.

3、制動壓力太低，摩擦片之間的摩擦力太小。采取措施：檢查壓力閥Y一10B的工作壓力，根據要求將其壓力調0.6MPa。

3. The braking pressure is too low, and the friction between the friction plates is too small. Measures taken: Check the working pressure of pressure valve Y-10B and adjust its pressure to 0.6MPa as required.

4、導軌絲杠廠家提醒，主軸箱內潤滑油太多，影響摩擦片之間的制動摩擦力。采取措施：調節(jié)主軸箱潤滑油節(jié)流閥，觀察主軸箱油標只有少量潤滑油滴下即可，若潤滑油太多來不及回油，使摩擦片之間存在潤滑油，會影響制動摩擦力。

4. The manufacturer of the guide screw reminds that there is too much lubricating oil in the spindle box, which affects the braking friction between the friction plates. Measures taken: Adjust the lubricating oil throttle valve of the spindle box and observe that only a small amount of lubricating oil drops from the spindle box oil level. If there is too much lubricating oil and there is no time to return it, there will be lubricating oil between the friction plates, which will affect the braking friction force.

二、主軸箱主軸自動變速不平穩(wěn)產生沖擊

2、 Impact caused by unstable automatic transmission of spindle box and spindle

1、控制主軸箱主軸自動變速電磁鐵斷電和通電的時間繼電器失靈。采取措施：檢查控制電磁鐵YT6、YR、YT9、YT10和YT11的時間繼電器調整是否正確，應使需斷電的電磁鐵先斷電，再使應通電的電磁鐵稍遲通電，使摩擦片脫開和結合平穩(wěn)。

1. The time relay that controls the automatic speed change electromagnet of the spindle box to power off and on is malfunctioning. Measures taken: Check whether the time relays for controlling electromagnets YT6, YR, YT9, YT10, and YT11 are adjusted correctly. The electromagnets that need to be powered off should be powered off first, and then the electromagnets that should be powered on should be powered on slightly later to ensure smooth detachment and bonding of the friction plates.

2、主軸箱變速進油路中節(jié)流閥未調整好。采取措施：適當調整針狀調速閥，以便實現(xiàn)離合器的斷開、吸合有過渡時間，使得主軸變速制動時的慣性沖擊能量被，以達到主軸變速時平穩(wěn)無沖擊。

2. The throttle valve in the transmission oil inlet of the spindle box is not adjusted properly. Measures taken: Adjust the needle shaped speed control valve appropriately to achieve a transition time for clutch disconnection and engagement, so that the inertia impact energy during the spindle speed change braking is eliminated, in order to achieve a smooth and impactless spindle speed change.

三、主軸箱不能移動的故障

3、 Fault of spindle box not moving

1、機床坐標軸上的聯(lián)軸器松動，應擰緊緊固螺釘。

1. The coupling on the coordinate axis of the machine tool is loose and the fastening screws should be tightened.

2、卸下壓板，觀察其是否研傷，調整壓板與導軌的間隙，保證間隙為0.02—0.03mm。

2. Remove the pressure plate, observe if it is scratched, adjust the gap between the pressure plate and the guide rail to ensure a gap of 0.02-0.03mm.

3、檢查主軸箱鑲條，松開鑲條上的止退螺釘，順時針旋鑲條螺栓，在使坐標軸能靈活移動、塞尺不能進入后，鎖緊止退螺釘。

3. Check the spindle box insert, loosen the stop screw on the insert, turn the insert bolt clockwise, and lock the stop screw after allowing the coordinate axis to move flexibly and the feeler gauge to not enter.
