ABRASIVE TOOL AND USE OF SUCH ABRASIVE TOOL Russian patent published in 2020 - IPC A45D29/05 A45D29/14 B24D3/00 B24D7/00 B24D3/34 B24D9/00 

FIELD: machine building.

SUBSTANCE: invention relates to abrasive tool, including abrasive agent carrier (1), which has shaft (2) for connection of carrier (1) of abrasive means with a drive to rotate carrier (1) of abrasive means around longitudinal axis (X) and core (3), which is connected to axial end (4) of shaft (2), and abrasive means (15) with closed in circumferential direction around longitudinal axis (X) surface (16), which surrounds hollow space (17) passing along longitudinal axis (X). At that, core (3) is at least partially arranged in hollow space (17), and wherein core (3) consists of mixture of materials, which has plastic with heat conducting filler, wherein plastic is made foamed, and filler has thermal conductivity of more than 35 Watt per meter and on Kelvin.

EFFECT: technical result is improved characteristics of the carrier of the abrasive agent, which is easier to handle and reliably prevents heat-related damages on the abrasive agent carrier or on the treated object, even during longer grinding cycles.
