TOOL HEAD AND TOOL SYSTEM WITH TOOL HEAD Russian patent published in 2021 - IPC B23C3/12 

FIELD: metal processing.

SUBSTANCE: group of inventions relates to metal processing by cutting; it can be used for processing part edges. Tool head (1) contains first working part (6) with a set of first knives (7) distributed along the perimeter and second working part (8) with a set of second knives (9) distributed along the perimeter. Second knives (9) are located in a circular direction between first knives (7). Second working part (8) is installed with the possibility of reciprocating movement in the direction of longitudinal axis (5) relatively to first working part (6) between a passive position and an active position provided that second knives (9) in the passive position are withdrawn back in the axial direction relatively to first knives (7), and in the active position, they protrude in the axial direction between first knives (7). Switching mechanism (10) below the tool head is made with the possibility of controlling the reciprocating movement of second working part (8) between the passive position and the active position. A tool system contains specified tool head (1) and an actuating element that are installed with the possibility of movement relatively to each other in the axial direction.

EFFECT: rearrangement and fixation of knives are simplified.
