The GRATA fl oor-type machine tools are designed for precise line-coordinate milling, drilling, boring, milling and thread cutting. They are particularly suitable for machining of box- and plate-type workpieces and complicated workpieces from cast-iron, steel cast-iron, steel and other machinable materials, mainly large as well as the largest sizes and weights. The machines are equipped with an extensible toolholding slide, which can be fi tted with a broad range of additional devices that signifi cantly enhance the machine‘s potentialities. The machines are suitable for series manufacture as well as demanding technological applications. They are continuously controlled in three basic coordinates (X, Y, Z) or other axes according to the used special equipment by the machine‘s control system.
