Machining unit used for producing material connections, especially wood connections, comprises a first machining tool used in a stable diameter in an initial step

摘要

Machining unit comprises at least two rotating or oscillating machining tools (8, 11). A first machining tool (8) is used in an initial step in a stable diameter (9) accordingly adapted to the machining. At least one second machining tool (11) with a very small diameter (12) is used in a finishing step to remove the remaining radius of the first machining tool. Preferred Features: The machining tools are each fixed at both ends in a tool holder (20).
