If the screwing depth for T-nut of the 

top jaw mounting bolt is shallow, T-

nut may be damaged. Also, the jaw 

or workpiece discharges thus result-

ing 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 top 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.

The following table describes the pro-

gripping, internal gripping and high 

accuracy gripping.

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。

请按照如下方法进行软爪的成型工作。(

外径或內徑夹  及  需要高夹持精密度时

請參照以下方 法)
