What kinds of tool handles are there in the machining center?

According to the taper hole of machining center spindle, it is usually divided into two categories, namely, general system with taper of 7:24 and HSK vacuum system with 1: 10. Generally, there are five standards and specifications for general tool rest with 7:24 taper, namely NT (traditional type), DIN6987 1 (German standard), IS07388/ 1 (international standard), MASBT (Japanese standard) and ANSI/ASME (American standard). The German standard of NT tool rest is DIN2080, which is used to fasten the tool rest on the traditional machine tool through the pull rod, also known as ST in China; The other four kinds of tool handles are all pulled at the end of the tool handle and tightened on the machining center. At present, DIN6987 1 (JT) and MASBT are the most widely used tool handles in China. DIN6987 1 tool holder can be installed on DIN6987 1 and ANSI/ASME spindle taper hole machine tools, while IS07388/ 1 tool holder can be installed on DIN6987 1, IS07388/ 1 and ANSI/ASME spindle taper hole machine tools.

1: 10 HSK vacuum tool holder

The German standard of HSK vacuum tool rest is DIN69873, and there are six standards and specifications, namely

Commonly used are HSK-A, HSK-B, HSK-C, HSK-D, HSK-E and HSK-F:

HSK-A (automatic tool changing with internal cooling), HSK-C (manual tool changing with internal cooling) and HSK-E (automatic tool changing with internal cooling, high-speed type).
