Abstract

A disc cutter body includes a hub (1), a transient portion (2) containing a composite material (CFRP) comprising wound and laid carbon fibres with density of the composite material ranging from 1.5 to 1.9 g/cm3, and a rim (3) provided with multiple connection sockets for connection of cutting inserts (5). The hub (1) and the rim (3) are linked up by a self-supporting composite material only to limit transfer of undesired high-frequency oscillations from the hub (1) to the rim (3), and vice versa. A glued joint is used on the connection surfaces (10) between the hub (1) and the transient portion (2), and between the transient portion (2) and the rim (3). The transient portion (2) includes at least one plate body (8) made of the composite material. The boundary contour (7) of a connection surface (10) between the hub (1) and the transient portion (2) and/or between the transient portion (2) and the rim (3) has regular undulated shape with a defined distance of wave peaks on the circle for torque transfer from the hub (1) to the transient portion (2) and/or from the transient portion (2) to the rim (3).
