SSGP 868 is a fully synthetic chemical solution specially designed for a wide range of cutting applications for most of the materials including steels, cast iron, cuprous metals and aluminium and their alloys. Cast iron is very difficult to machine because there are finest chips floating on the coolant and it will darken the coolant, dirty the machine and cause rust. Thanks to the great effort of investigation by Locks’ R&D, SSGP 868 can effectively settle down the chips and eliminate this problem.
