Abstract
The introduction of segmented diamond tools has revolutionised the whole stone processing sector by allowing dramatically increased material removal rates. This is especially true for the processing of marble, where the production of modular elements for the building sector has been facilitated by the machine tool and grinding tool developments of the recent years. With circular diamond tools, it is possible to machine grooves of depths similar to the intended workpiece width (300-400 mm) by only one stroke at feed speeds of about 1 m/min. Typically, cutting depths of 1 mm are common in combination with feed speeds of approx. 12 m/min on block cutting machines. Typically in cutting of hard granite cutting depths deeper than 25 mm cannot be realised because of thermal and mechanical overload of the blade. Thus, the productivity when sawing hard granite is only about 4% of the respective one for marble. To overcome this specific problem, under the head of the Brite-EuRam II programme a consortium of well-known companies and research institutes has been working together. Regarding the situation in the stone industry, research work as it was intended in this project has brought a new dimension into this field. An emphasis was placed on overall approaches taking into account technological, economic and environmental considerations only the co-operation of strong partners could have led to successful results of the aim to increase cutting depth up to 300 times.
