In this department all milling, diamond cutting, and drilling operations are carried out on the balls coming from the turnery. For the above mentioned processes, drilling machines, diamond cutting machines and transfer machines are used. In this department, valve balls with dimensions between 10 mm and 80 mm are processed. The product thus obtained is ready to be shipped, or to be sent for chrome plating if requested by the customer. The machines of the this department are constantly monitored in order to guarantee that the manufacturing process is carried out in compliance with the requested manufacturing standard.

The balls of big diameters are not obtained by brass bars, but by forging. The company has established a department with two completely automated working isles producing end-products from the raw products obtained through forging. These working isles carry out drilling, milling and diamonding operations onto the balls for valves with diameters from 31 to 82 mm.
