Drilling various diameter holes and glass milling is carried out on a special drilling-milling machine delivering water blasts on a cutting tool. Drilling holes on the glass is done through double-sided diamond drills delivering. Upon launching, the lower drill is delivered automatically which cuts the glass from its 20% of thickness, afterwards it moves backwards and the upper drill is delivered automatically; the main drill to carry out the final drilling. Double-sided drills prevent the formation of chips on the glass lower sheet. Diameter diapason of the processing hole is from 3mm to 100mm. Milling of the cuttings for the furniture is done manually by using special diamond mills. All the procession is carried out under a water-blast.
