Dab tsi yog qhov tseeb theem ntawm cov yuam sij locking inserts?

The accuracy level of key locking insert is usually classified according to international standards or national standards. The accuracy level usually covers the dimensional accuracy of the inner hole of the thread insert and the quality of the thread. Here are some common accuracy classes for key locking thread inserts:

1. 4H/5H/6H grade:

These grades are mainly used for the dimensional accuracy of the inner hole of the thread insert. The smaller the number, the higher the accuracy. Typically, 4H is used for high-precision applications, while 6H is used for general engineering applications.

2. 4G/5G/6G grade:

These grades are typically used for thread quality in threaded inserts. 4G is typically used for high-precision applications, while 6G is used for general engineering applications.

Cov ntsiab lus tshwj xeeb thiab cov kev xav tau ntawm cov qib no yuav txawv raws li cov qauv thoob ntiaj teb sib txawv (zoo li ISO, Los ntawm) los yog lub teb chaws tus qauv. Xaiv cov qib raug tsim nyog ntawm qhov tseem ceeb locking insert yuav tsum tau txiav txim siab raws li qhov tshwj xeeb engineering xav tau thiab cov qauv. Typically, cov qhab-nees raug siab yog haum rau cov ntawv thov uas xav tau qhov tseeb dua, thaum cov qhab-nees qis dua tuaj yeem siv rau kev siv engineering.
