Every six months, the ball screw and linear guide of each axis are re-greased. When operating, be sure to use the grease product specified by FANUC. Faults caused by the use of greases other than specified products are not covered by warranty.

　　1.重新潤滑 XY 軸的滾珠絲杠和線性導軌

　　1. Re-lubrication of ball screw and linear guide of XY axis⑴ 將 X 軸移動到機械坐標 X=0的位置（ Y 軸在明顯位置都無妨），拆除機械左側面的滑脂槍噴嘴口金屬板（ 2 塊）。

　　(1) Move the X-axis to the position of the mechanical coordinate X=0 (the Y-axis may be in any position), and remove the metal plate of the grease gun nozzle (2 pieces) on the left side of the machine.

　　這樣，就可以看到金屬板孔內的 XY 軸滾珠絲桿用滑脂槍噴嘴，從這里抽入滑脂槍．補充潤滑脂。

　　In this way, it can be seen that the XY axis ball screw in the hole of the metal plate is injected with a grease gun nozzle, from which a grease gun is drawn to supplement the grease.

　　每次向 XY軸滾珠絲桿補充的潤滑脂量為 2g 。等潤滑脂涂敷結束后，將滑脂槍噴嘴口 金屬板（ 2 塊）原樣裝好。

　　The amount of grease added to the XY axis ball screw is 2G each time. After the grease coating is finished, the metal plate (2 pieces) of the nozzle nozzle of the grease gun is packed as it is.

　　⑵ 接著，將 X,Y軸移動到行程的中心附近，切斷電源。如下圖所示，拆下左右的金屬板。此外，掀開左右的折皺保護罩。

　　(2) Next, move the X and Y axes near the center of the trip and cut off the power supply. As shown in the figure below, remove the left and right metal plates. In addition, lift the wrinkle shield around.

　　⑶ 用布塊擦掉粘附在下圖中所示的墊塊和滑軌部分上用舊的潤滑脂。等擦拭結束后，在滑軌部分涂上新的潤滑脂。

　　(3) Use cloth blocks to erase the old grease attached to the pads and slides shown in the figure below. After wiping, apply new grease on the sliding track.

　　⑷ 潤滑脂涂敷結束后，安裝剛才掀開的左右的折皺保護罩和左右的金屬板。

　　(5) After finishing the grease coating, install the wrinkle protective cover and the metal plate just lifted.

　　2、重新潤滑UV軸的導軌和滾珠絲杠

　　2. Re-lubricating the guide and ball screw of the UV shaft⑴ 將 U 軸移動到機械坐標為 C400IB : U ＝-60 ,C600IB ,C800IB :U＝-100 的位置(V軸在明顯位置都無妨），拆下機械的左側面的滑脂槍噴嘴口金屬板（ 2 塊）。這樣，就可以看到金屬板孔內的 U V軸滾珠絲桿用滑脂槍噴嘴，從這里插入滑脂槍，補充潤滑脂．每次補充給 U V 軸滾珠效杠的潤滑脂量為 2g 。等潤滑脂涂敷結束后，將滑脂槍噴嘴口金屬板（ 2 塊）原樣裝好。

　　(1) Move the U-axis to the mechanical coordinates of C400IB: U=-60, C600IB, C800IB: U=-100 (V-axis may be in any position). Remove the metal plate of the grease gun nozzle nozzle on the left side of the machine (2 pieces). In this way, we can see that the U V axis ball screw in the hole of the metal plate is injected with a grease gun nozzle, from which a grease gun is inserted to supplement the grease. The grease amount supplemented to the U V axis ball rod is 2G each time. After the grease coating is finished, the metal plate (2 pieces) of the nozzle nozzle of the grease gun is packed as it is.
                              

　　⑵ 然后切斷電源，如下圖所示拆下下面、左側面、背面（ C600IB,C800IB）的金屬板。

　　(2) Then cut off the power supply. Remove the metal plates below, on the left and on the back (C600IB, C800IB) as shown in the figure below.

　　⑶ 用布塊等擦掉粘附在下圖標記的墊塊部分和滑軌上的用舊的潤滑脂。等擦拭結束后在滑軌部分涂上新的潤滑。潤滑脂的涂敷結束后，安裝剛才拆除的下面、左側面、背面（ C600IB,C800IB ）的金屬板3、重新潤滑 Z 軸的滾珠絲杠⑴ C800IB 的Z500 選項機以外的情形(3) Use cloth blocks to wipe off the old grease attached to the pad part of the following icon and the slide rail. After wiping, new lubrication is applied to the slideway. After the grease coating is finished, install the metal plate on the lower side, left side and back side (C600IB, C800IB) which has just been removed. 3. Re-lubricated Z-axis ball screw (C800IB) other than Z500 selector.

　　將 Z 軸移動到機械坐標為 C400IB時： Z = -255 ，C600IB, C800IB時： Z = -310 ( C600iB 的 Z400 選項機時 Z = -410 的位置，拆除滑脂槍噴嘴口金屬板（ 1 塊）。這樣，就可以看到金屬板孔內的 Z 軸滾珠絲杠用滑脂槍噴嘴，從這里插入滑脂槍，補充潤滑脂．每次補充給 Z軸滾珠絲杠的潤滑脂量為2g。等潤滑脂涂敷結束后，將滑脂槍噴嘴口金屬板原樣裝好。

　　When the Z axis is moved to the mechanical coordinates of C400IB: Z = 255, C600IB, C800IB: Z = 310 (the position of Z = 410 when the Z400 machine of C600iB is selected), the metal plate of the nozzle of the grease gun (1 piece) is removed. In this way, we can see that the Z-axis ball screw in the hole of the metal plate is injected with a grease gun nozzle, from which a grease gun is inserted to supplement the grease. The grease amount supplemented to the Z-axis ball screw is 2G each time. After the grease coating is finished, the metal plate of the nozzle nozzle of the grease gun is packed as it is.

　　C800IB 的 Z500 選項機的情形將 Z 軸移動到機械坐標為 Z ＝-510 的位置。拆除滑脂槍噴嘴口金屬板（ l 塊）。在金屬板孔內．可以看到 Z 軸滾珠絲杠用的滑脂槍噴嘴，從這里插入滑脂槍，補充潤滑脂。每次補充給 Z軸滾珠絲杠的潤滑脂較為 2g 。等潤滑脂涂敬結束后，將滑脂槍噴嘴口金屬板原樣裝好。

　　In the case of C800IB's Z500 selector, the Z axis is moved to the position where the mechanical coordinate is Z=-510. Remove the metal plate (l block) of the nozzle of the grease gun. In the hole of the metal plate, you can see the grease gun nozzle for Z-axis ball screw. Insert the grease gun here to supplement the grease. The grease supplemented to Z-axis ball screw is up to 2G each time. After the grease coating is finished, the metal plate of the nozzle nozzle of the grease gun is packed as it is.

　　⑵ 然后， C400iB 的情形下將 Z軸調到較底下處（機械坐標 Z =-255）。C600iB C800iB的情形下將 Z 軸提升到較高處（機械坐標Z=0）。切斷電源，拆除下圖所示金屬板。

　　(2) Then, in the case of C400iB, adjust the Z axis to the bottom (mechanical coordinate Z = 255). In the case of C600iB C800iB, the Z axis is elevated to the highest position (mechanical coordinate Z = 0). Cut off the power supply and remove the metal plate shown below.

　　⑶ 用布塊等擦掉粘附在下圖標記的墊塊部分和滑軌上的用舊的潤滑脂。等擦拭結束后，在滑軌部分涂上新的潤滑脂．潤滑脂涂敷結束后，安裝剛才拆除的金屬板。

　　(3) Use cloth blocks to wipe off the old grease attached to the pad part of the following icon and the slide rail. After wiping, new grease is applied to the slideway. After the grease is applied, the metal plate just removed is installed.

　　對各軸的潤滑結束后，為使潤滑脂滲透進去，使軸在全行程下大約運轉 10 分鐘。

　　After the lubrication of each shaft is finished, in order to make grease penetrate into the shaft, the shaft will run for about 10 minutes under the whole stroke.
