Following on from the successful Centauro ALFA CNC milling/slotting machine, of which more than 60 have been installed in the UK to date, Centauro has introduced the all-new ALFA Twin model, which is a dedicated CNC milling machine for internal doors and frames.
The main advantage of the Twin over the standard machine is that a door can be simultaneously machined on both sides at the same time, without having to manually move or turn it. The result is a machined door with three hinge recesses, lock slot, face plate recess and handle/key hole in approximately two minutes. In addition, it is possible to machine two linings/jambs – again, both at the same time.
As standard, the ALFA Twin is equipped with six adjustable vacuum cups to hold the door in position while it is being machined. By utilising this system, both sides of the door can be fully machined without having to take into account the position of mechanical or pneumatic clamps, which, of course, are not needed.
For machining of the lock slot and drilling/slotting for the handle hole/key slot, there is a router head that automatically works in either the vertical or horizontal, and has a travel distance in the X axis of 2800mm and in the Y axis of 150mm (although optionally this can be extended to 600mm).
On the opposite side there is a horizontal milling head that is used for producing the hinge recesses – again with a 2800mm X axis travel. On request it is possible to equip either one or both sides with an additional horizontal milling head that can be used to make the small pilot hole for hinge or lock screws and/or to machine a square corner hinge or lock recess.
When processing linings/jambs, adjustable pneumatic clamps are fitted. Programming is extremely quick and simple, thanks to the latest-generation 10in graphic colour touchscreen controller, with pre-installed electronic macro templates.
Door width working capacity is maximum 950mm and minimum 650mm, but optionally this can be increased to 1100 and 800mm, respectively. Other options include motorised positioning of the door on driven belts, infeed and outfeed roller tables, and an uprated router head motor of 5.6kW.
Exclusive UK agent JJ Smith has an ALFA Twin set up and readily available for demonstration in its Liverpool showroom. The company believes this competitively priced machine will prove ideal for the many companies which need a quick, simple and efficient machine for processing doors and linings. In addition to offering the ALFA and Twin models, JJ Smith also supplies a range of throughfeed, high-volume door production lines from specialist manufacturer Essepegi.
