It is of no importance whether a milling cutter with high-speed spindle or a simple scraper are used. In most cases only a suitable compensation mechanism will bring the required process safety for automation of a trimming operation. Our trimming experts are able to make statements on the feasibility of automation tasks already in an early experimental stage.
