Power Chuck

1. Remove the water from water cup of the 
    air unit periodically, in order to prevent the
    transformation or abnormal abrasion of 
    0-rings in cylinder, and then shorten the 
    service life.

2. Fill in lubricant (ISO: VG 32) to oil cup of 
    the air unit periodically, to ensure the 
    lubricant is sufficient.

3. Adjust the flow rate valve above the
    rotating oil cup to normal feeding amount, 
    the normal feeding amount is 2~3 drops 
    per chuck movement.

4. Adjust air pressure at least within 
    2~2.5kgf/cm

2

 (0.2-0.25Mpa) and confirm 

    the operation of electromagnetic 
    valve(manual valve) is normal.

5. Adjust the air pressure to 7kgf/cm

2

    (0.7Mpa) then check if there is leakage.

 (0.2Mpa) 

for test run, then check with following
checking steps.

- Check the operation of the chuck if it is 
   smooth.
- Check the direction of the operation if it is 
   correct.
- Check the stroke of the operation if it is 
   enough.(stroke of the chuck)
- Check every tubes if there are leaking.

Check the steps above correctly, then adjust 
the required pressure and re-check again.

1. 에어유니트의 워터 컵에서 주기적으로 물을 
    제거해 실린더의 오링 변형이나 과도한 마모
    를 방지하고, 그에 따라 사용수명 단축을
    방지합니다.

2. 주기적으로 에어유니트의 오일 컵에 윤활유
    (ISO: VG 32)를 채워 윤활유를 항상 충분
    하게 유지합니다.

3. 회전 오일 컵 위의 유속 밸브를 정상 공급량
    으로 조정합니다. 정상 공급량은 척 움직
    임당 2~3방울입니다.

4. 공기 압력을 최소한 2~2.5kgf/cm2 (0.2-
    0.25Mpa) 이내로 조정하고, 전자기 밸브
    (수동 밸브)가 정상적으로 작동하는지
    확인합니다.

5. 공기 압력을 7kgf/cm2 (0.7Mpa)로 조정한 
    후 누출 여부를 확인합니다. 

시운전 중 공기 압력을 2kgf/cm2 (0.2Mpa)
로 조정한 후 다음과 같은 점검 단계로 검사
합니다.

- 척의 작동이 원활하게 이루어지는지 점검
  합니다.
- 작동방향이 정확한지 점검합니다.
- 작동 스트로크가 충분한지 점검합니다.
  (척의 스트로크)
- 모든 튜브를 점검해 누출 여부를 확인합니다.

위의 단계를 정확히 점검한 후 요구되는 압력을 
조정하고 다시 점검합니다.

1. 要定期从 Air Unit 的 Water Cap 清
   除水,以防止气缸O形环变形或过度磨
   损,及因此而导致的使用寿命的缩短。

2. 定期补充 Air Unit 的 Oil Cup 的润
   滑油(ISO: VG 32),以始终充分保持
   润滑油。

3. 将回转 Oil Cup 上的流速阀调节成正
   常供给量。正常供给量是卡盘每移动
   为2~3滴。

4. 空气压力要至少调节成2~2.5kgf/cm2 
   (0.2- 0.25Mpa)以内,检查电磁阀(手
   动阀)是否正常工作。

5. 将空气压力调节为7kgf/cm2 (0.7Mpa)
   后,检查有无泄露。

在试运转中将空气压力调节为2kgf/cm2 
(0.2Mpa)后按如下检查程序进行检查。

- 检查卡盘动作是否正常。
- 检查动作方向是否正确。
- 检查动作行程是否充分。
  (卡盘行程)
- 检查所有管子是否有泄露。

按如上程序进行正确检查后,调节所需压
力,重新检查。
