소프트 죠 는 공작물의 형상, 치수, 재질, 면조
도, 절삭 조건등을 고려해서 최적의 것을 사용
해 주십시오.

使用软爪时,应参考加工产品的外形、尺
寸、材料 表面粗度和切割条件等,选择最
佳的软爪.

Fit a suitable soft jaw according to the 
shape, size, material, surface roughness and 
cutting conditons of the workpiece.

若顶爪安装螺检和四爪钉的拧紧深度较
浅,四爪钉会损坏,且加工产品存在着飞
散出去的危险.另外,若四爪钉的底面有螺
检露出来,由于无法固定顶爪,加工产品
也有飞散出去的危险.因此, 应使顶爪梓
紧螺检的长度比四爪钉的底面短0~1mm左
右.(Fig.9)
最好不要使用我公司以外的其它拧紧螺
检.(若使用不是我公司生产的其它螺
检,请务必使用强度为 12.9(M22以上时
为 10.9)以上的螺检,并特别注意螺检的
长度.
 若四爪钉没拧紧,主轴启动时,顶爪有轴
启动时,顶爪有甩出去的危险.

If the screwing depth for T-nut of the top jaw 
mounting bolt is shallow, T-nut may be dam-
aged. Also, the jaw or workpiece discharges 
thus resulting in danger. If the bolt protrudes 
from the T-nut bottom, the top jaw is not 
fixed even if the mounting bolt is tightened. 
Also, the jaw or workpiece discharges thus 
resulting in danger, consequently, the overall 
length of the op jaw mounting bolts should 
be 0~1mm from the T-nut bottom.(Fig.9)
Be sure to use the attached T-nut and 
mounting bolt.In an unavoidable case, use 
the bolt and nut of strength 12.9(M22 or 
more 10.9) or more and sufficient length.
Never start the spindle with T-nut still loose. 
The top jaw will discharge.

탑 죠 부착볼트와 T-너트의 체결 깊이가 짧을 
경우에는 T-너트가 파손되고 공작물이 비산될 
위험이 있습니다. 또, T-너트 밑면에 돌출되게
체결 볼트를 조립하면 탑 죠가 고정되지 않아 
공작물 비산의 위험이 있습니다. 따라서 탑 죠 
체결 볼트의 길이는 소프트죠 체결시 T-너트의 
밑면보다 0~1mm정도 짧게 하십시오.(Fig.9)
삼천리 부속의 T-너트 및 체결볼트 외에는 사용
을 금해 주십시오. 만약에 삼천리 이외에 체결 
볼트를 사용하실 때에는 강도 구분 12.9(M22 
이상은 10.9)이상과 길이에 특히 주의 하십
시오.
T-너트가 느슨하게 체결되면 주축 회전시에 탑 
죠의 비산 위험이 있습니다.
