The device (10) has shaft (30) that is connected to motor and motor flange (14) for bearing shaft. A grinding surface of housing (16) is arranged facing motor and driving motor is provided to drive grinding surface with shaft such that grinding surface rotates in housing about rotational axis. The housing is releasably fixed to motor flange and grinding surface is arranged on side of motor flange. The motor flange is formed by sleeve (21), which is adapted to be fixed to housing such that opening formed in housing extends from housing circumference towards grinding surface facing motor. |
