- Several different milling blanks are fixed on a rotating metal disc. A transport mechanism grips a blank and feeds it into a CNC milling machine. A robot arm in the CNC machining centre moves into an extensive tool magazine with various milling spindles and picks up the programmed tool. The CNC-controlled milling process on the metal blank begins.Laro NC-Technik uses pallet changing systems to produce both series and individual items fully automatically. Around the clock and at weekends. This enables us to achieve maximum production quantities in the shortest possible time at favourable conditions.
