FIELD: drilling of soil or rock.
SUBSTANCE: group of inventions relates to cutting machines for the destruction of the surface of the rock. Cutting unit for the cutting machine comprises a shaft that is mounted on the machine and one end of which extends from the machine, and a cutting device located in connection with said end of the shaft. In this case, the cutting device is connected to the shaft with the possibility of detachment and preventing rotation with respect to the shaft by means of a locking assembly. Locking node contains the first locking device located and configured to transfer essentially axial loads, and a second locking device disposed and configured to transfer substantially radial loads.
EFFECT: facilitating the installation and maintenance of the cutting device.
