FIELD: material processing.

SUBSTANCE: invention relates to material processing by cutting and can be used in processing surfaces with electric tools. The milling machine contains a base, a housing, a motor for rotating the shaft, at the free end of which a tool holder and a cutting tool are installed. The base is made with a hole for the passage of the cutting tool attached to the tool holder during the processing of the workpiece and is connected to the body by means of one or more support nodes. A sleeve is placed on the base, limiting the area in which the cutting tool, the tool holder and the hole in the base are located. The sleeve contains a side wall extending from the base to the housing, and guides for moving dust and waste to the outlet in the form of a part of the connector, which is configured to automatically move to a set position from the first and second positions of the cutting tool relative to the specified outlet and contains an annular assembly, the ring of which is made with the possibility of rotation relative to the connector to accommodate the channel end of the dust and waste removal device.

EFFECT: effective removal of dust and waste is secured, and the tool visibility is improved.
