PRODUCTION OF BALLS FOR VALVES
In this department are carried out all milling, diamonding and drilling operations on the balls for valves coming from the turnery. For the above mentioned operations the company uses drilling and diamonding machines as well as transfer machines. In this department are processed balls for valves of dimentions between 10 mm and 30 mm. The product here obtained is ready to be delivered to the customer, or can be sent to the chroming department upon request by the customer. The many machines of the department are constantly monitored in order to garantee that the manufacturing process is carried out in compliance with the requested manufacturing standard.
The balls of big diamters are not obtnained by brass bars but by forging. The company has established a department with two completely automated working isles producing end-products from the row 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. The creation of the two working isles has enormously reduced the time of manufacturing and has improved the quality of the final products. In order to optimize manufacturing costs for the end-product price, balls for bigger valves are lightened for what non-essential parts concerns, according to their specific use.
