The vertical numerical control for glass are machines just proposed on the market. They arrive from 2 directions:
-The traditionnal driling machines suppliers who started from a vertical drilling machines and added other options( milling, edging, polishing..)
-New suppliers comming directly on the market with this machine ( sometimes from stone market)
The main advantages are:
-Area spare
-On line working ( washing..), with less operator interventions, less scratches and productivity improving
-Double spindle drilling
But now these machines offer less options than the horizontal traditionnal ones.
The glass pieces drops ( milling) are to be study carefully.
