TECHNOLOGICAL MACHINE Russian patent published in 2021 - IPC B24B45/00 B27B5/32 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a technological machine (211), in particular a hand-held machine, preferably an angle grinder, including a holder (213) mounted with the possibility of performing a rotational movement around the axis (A) of the output shaft and configured to hold the working tool (11) in particular of the replaceable working tool on the technological machine (211) in such a way so that the axis (A) of the output shaft and the axis (a) of rotation of the tool coincide. The holder (213) has at least one driver (215) and a clamping mechanism (217) movable relative to the driver (215). The driver (215) for transmitting the driving force to the working tool (11) has at least one torque transmission region located at a distance from the axis (A) of the output shaft. The driver (215) and the clamping mechanism (217) are provided for penetration through the recess (17) of the working tool (11), in particular, passing through the entire thickness of the material of the working tool (11), and clamping the working tool (11) using the clamping mechanism (217), movable in the radial direction with respect to the axis (A) of the output shaft.

EFFECT: increase in the possible immersion depth of the working tool into the workpiece is provided.
