FIELD: mechanics.
SUBSTANCE: fretsaw comprises drive, made as a coupled flexible transmission; lead, connected to a link, is attached to both flexible elements of the transmission; at that the link performs reciprocal movements on the guides and it is coupled with an executing tool. Executing tool is installed so that it transfers the vertical force onto a roller, and two leading rollers, installed in the link on the lead, rotate in opposite directions.
EFFECT: reduction of tool vibration and increase of tool durability.
