MAXIM SEMI-SYNTHETIC GS4 DATAFILE

PREMIUM CUTTING AND GRINDING FLUID (Printable PDF File)

MAXIM SEMI-SYNTHETIC GS4 is a water extendible, semi-synthetic cutting and grinding fluid formulated to perform exceptionally in a variety of machine operations.

MAXIM SEMI-SYNTHETIC GS4, when mixed with water, forms a water-thin transparent micro-emulsion that exhibits excellent cooling properties for superior finishes and increased tool life. GS4 is recommended for use in operations involving the most difficult to machine alloys including stainless, titanium and high nickel steels. The opaque emulsion is non-foaming, silicon free, and easy to mix in both soft and hard water.

MAXIM SEMI-SYNTHETIC GS4 remains highly transparent to afford the machine operator full view of the work.

The effective biostatic system formulated into the GS4 yields a higher resistance to microbial degradation and rancidity than conventional soluble oils; this allows for longer coolant life in machine sumps and central coolant systems without special maintenance procedures. Unlike many solubles and synthetics, the GS4 remains fluid in and on the surfaces of the machining center allowing slideways, chucks, and tooling to work freely without a hard-to-clean dry or sticky residue.

MAXIM SEMI-SYNTHETIC GS4 incorporates a three part DEA FREE rust inhibitor package that provides complete protection for machine surfaces and parts in process. GS4 also contains a copper brightner as well as an inhibitor to prevent galvanic corrosion between stacked parts. This feature makes GS4 well suited for the machining of copper and its alloys as well as a variety of machine operations on aluminum and most aerospace alloys.

MAXIM SEMI-SYNTHETIC GS4 has met the criterion concerning corrosive characteristics of metalworking fluids on various metals set forth by the major D.O.D. contractors.
