Centauro - produce three different models of machine; the ALFA, ALFA Twin and ALFA Jamb. The hugely successful ALFA model is ideal for the customer looking for a cost-effective solution for machining doors and frames. Simple to set up / program, it is ideal for hinge recessing, lock case slotting, 3-point locking systems and making handle holes and key slots. To date there are over 80 ALFAs installed in the UK and Ireland, 95% of which are working on doors and frames. The ALFA Twin is a through feed machine that can simultaneously machine both sides of a door in just two minutes. The 'new' ALFA Jamb is also equipped with an infeed loading and outfeed unloading system, maximising production output of frames / jambs.
