CGS Srl has included a Sunnen automatic lapping machine in its Reprocessing Department: with this choice, the company once again confirms its firm desire to establish itself and specialise more and more in the hydraulics sector, since, thanks to this investment, it is now able to produce coupled valves internally, both jackets and spools, with tolerance ranges even in the order of 0.002- 0.003 and low roughness below Ra 0.15.
