BRETON Contourbreton NC 260 K23 stone machining center was built in
2010 in Italy by Breton S.p.A.. The machine is used for the efficient
machining of natural stone slabs and blocks with a maximum weight of
4000 kg. It enables a number of advanced operations to be performed,
such as milling, profiling, bevelling and hole drilling. All these
machining processes are performed fully automatically, while
maintaining the high repeatability and quality of the manufactured
parts. The reliable spindle, operating at a maximum speed of 9000 rpm,
moves in three numerically-controlled axes. This enables precise
positioning of the tool relative to the workpiece during the
machining. All axes, driven by powerful motors, achieve a high feed
rate and dynamics, which in turn translates into increased production
efficiency. All of this makes the offered Contourbreton NC 260 K23 CNC
machining center for marble and granite an excellent choice for the
production of kitchen worktops, stairs, window sills and other
elements made of marble and granite. The total weight of the machine
is 8000 kg.
