Gonvauto Asturias invests in antirust and advanced tube saw blade lubrication system

we don’t wash off the oil applied prior to cutting. This has greatly reduced our oil consumption whilst improving the protection on our products.” The Dietronic saw blade lubrication system has the control system and oil tank remotely mounted from the saw carriage to reduce weight load. A specially designed spray nozzle with three outlets ensures precise application of cutting oil on all areas of the blade teeth. An additional low temperature cold gun spraying air at -20°C reduces the cutting temperature and increases saw blade life. The combination of the Antirust system together with the minimum quantity lubrication of the saw blade ensures that the tubes and profiles exit the mill fully protected against corrosion during storage and transportation.

IN May 2024 Gonvauto Asturias, part of the Gonvarri group, with headquarters in Spain, ordered a new Dietronic Antirust 08 system for one of its precision tube mills located in Corvera, Northern Spain. The order follows the previous installation of a Dietronic advanced saw blade lubrication system on the same tube mill in February 2024. The MQL saw blade system is installed on a tube mill producing precision tubes for automotive applications in the range 40mm to 130mm in diameter and equivalent profiles. Adrián Fernández, production manager at the Asturias plant, said: “We chose Dietronic for the Antirust and saw blade system to improve the quality and control of oiling on our products. It was extremely important to accurately apply the amount of rust prevention oil to the tubes and consequently maintain the protection during the cutting phase so
