Description

Technical Field

[0001] The utility model relates to the field of tool grinding, in particular to a tool through-hole grinding wheel facilitating replacement of a kit. Background Technique

[0002] The grinding wheel for grinding the through-hole of a tool is an important tool for precision repair and grinding of the through-hole of a tool in grinding processing.

[0003] After retrieval, a tool through-hole grinding wheel facilitating replacement of a kit, disclosed in Chinese Patent No. CN 207448255 U, includes a grinding wheel body. A cavity is arranged inside the grinding wheel body. A bracket is arranged inside the cavity. A small blower is arranged on the surface of the bracket. An air inlet pipe connecting to the surface of the grinding wheel body is arranged on the surface of the small blower. An air delivery pipe is further arranged on one side of the small blower.
