Abstract
Sales of multi-task machine have increased rapidly in recent year. However, the interface between the machine spindle and the tool holder does not exist as a common standard. Therefore, the committee (Interface Committee for Turning Mills, ICTM) was organized to make a new opened standard. As a result of this activity, ICTM-HSK standard based on ISO-HSK was established in October 2002. This standard has been proposed to ISO as the HSK-T type in 2005. The condition of HSK-T in ISO will be reported here.
