Metalworking Fluids and Metal Processing Oils

Schaeffer manufactures a complete line of superior quality metalworking fluids for use in a wide variety of applications. Schaeffer's Metalworking Fluids do not contain chlorine, nitrites, phenols or diethanolamine (DEA) of heavy metals. Schaeffer's proprietary micro-emulsion metalworking technology provides a biostatic and bio-resistant, non-staining, semi-synthetic metal removal fluid that is recommended for use in a multitude of machining and grinding operations on both ferrous and non-ferrous metals.

Schaeffer metalworking fluids contain a unique group of surface active ingredients, lubricity, anti-weld and extreme pressure additive systems that work in synergism which enables the products to wet and coat the metal surfaces of the tool and workpiece interface in order to provide a protective film that improves the film lubrication boundary characteristics, chip carrying capabilities and heat dissipation properties of the fluid. These coolants contain a combination of properly balanced wetting agents that allows the penetration of the fluid directly into the cutting zone to form a chemical/metal bond that reduces friction and rapidly cool the part/tool interface through a physical characteristic call inverse solubility.

The combination cooling and extreme pressure/lubricity properties engineered into Schaeffer coolant's inverse solubility properties effectively transfers heat away from the cutting zone, thus reducing friction between the cutting tool and the work-piece. This in turn results in greater dimensional accuracy, higher turning speeds and feeds, prevention of the chips from welding to the cutting tools, improved surface finish and extended tool life.

Schaeffer coolants last longer. All Schaeffer coolants utliize an extremely stable and tight micro emulsion system that allows them to be mixed with water at varying concentrations. The micro emulsion system enhances the rust and corrosion  inhibitors' alkaline reserve during use, resulting in the product's ability to resist rancidity, a drop in pH and provide superior bioresistance and biostability. The micro emulsion system is less susceptible to attack from bacterial growth, resulting is less degradation of the fluid during use. This allows Schaeffer coolants to last longer. The unique formula is less likely to sour and produce odors resulting in longer sump life and fewer worker complaints.

The antifoam additive system in Schaeffer coolants provides rapid foam collapse and a high degree of stability during use. This results in a sufficient amount of the cutting fluid being available to the tool-work-piece interface, greater visibility of the work-piece and a vast reduction in maintenance problems due to coolant overflow.

Schaeffer coolants will reject a very high percentage of tramp oil contamination allowing for easy skimming and removal of the tramp oils from the sumps and reservoirs. This results the elimination of a potential food source for the growth of bacterial and fungus in the sump and greater bioresistance to the growth of bacteria and fungus in the coolant sump.
