Method of producing brushes, and brush-production machine

The method involves reducing a measuring-throughput at a working position when rotation speed of a machining tool (7) e.g. drilling tool (5) and tamping tool (6), exceeds a maximum value at the working position. The measuring-throughput is increased at the working position when the rotation speed falls below the maximum value. The modified rotation speed values are stored at the individual working positions such that production-throughputs are carried-out during the measuring-throughput based on the determined and stored rotation speed values. An independent claim is also included for a brush manufacture machine.
