Punching device for rotary processing of to-be-processed material, has engagement portion whose pivot axis is provided in tool axis direction and/or perpendicular to tool axis direction based on theoretical center of engagement portion

摘要

The device (1) has tools (4,5) that rotate in tool axes (x,y) in an engagement portion of tooth flanks engaged with synchronization gears in predetermined circumferential orientation to each other. The tool (4) is pivoted relative to the tool (5) about a pivot axis (z) without the intervention of the synchronization gears suspended to one another. The pivot axis of the engagement portion is provided in the tool axis direction and/or perpendicular to the tool axis direction based on theoretical center of the engagement portion.
