PORTABLE MACHINE AND SYSTEM FOR PROCESSING ARTICLES Russian patent published in 2016 - IPC B24B55/00 B24B45/00 B24B23/02 B27B5/32 

FIELD: machine building.

SUBSTANCE: invention relates to design of portable technological machine. Portable machine, primarily hand-held machine, contains at least one spindle (12a; 12b; 12c; 12d; 12e; 12f; 12g; 12h; 12i; 12j; 12k) for installation and driving working tool (14a; 14b; 14k), at least one brake assembly (16a; 16b; 16k) for braking of at least in spindle braking mode (12a; 12b; 12c; 12d; 12e; 12f; 12g; 12h; 12i; 12j; 12k) and/or working tool (14a; 14b; 14k), at least one safety unit (18a; 18b; 18c; 18k) to prevent spontaneous separation of the working tool (14a; 14b; 14k) from spindle (12a; 12b; 12c; 12d; 12e; 12f; 12g; 12h; 12i; 12j; 12k) at least in braking mode and coding unit (20a; 20b; 20c; 20d; 20e; 20f; 20g; 20h; 20i; 20j) for encoding connector at least between spindle (12a; 12b; 12c; 12d; 12e; 12f; 12g; 12h; 12i; 12j; 12k) and safety unit (18a; 18b; 18c; 18k). Coding unit (20b) is made in form of an electronic, electric, optical, magnetic and/or electromagnetic coding unit (20b). Proposed system comprises portable processing machine (10a; 10b; 10k) and at least one replaceable module (40a, 40b; 40k), made in form of brake unit (16a; 16b; 16k).

EFFECT: technical result consists in improvement of safety during operation of machine.
