Poly(alkylene glycol)s are also used as lubricity additives ia water-based synthetic cutting and grinding fluids (36), and ia aqueous metalworking fluids. Under the high frictional heating at the tool or die contact with the workpiece, the polyalkylene glycol comes out of solution ia fine droplets which coat the hot metal surfaces. 

Uses Lubricant, antiwear agent for metalworking fluids, sol. oils, semisynthetics, synthetics, syn. cutting and grinding fluids, boundary lubrication, metal removal corrosion inhibitor for ferrous and nonferrous metals wetting agent Features Stable in hard water Properties COF 0.047 Maxiube LA-61 [PCC Chemax]... 

Drift and Mist Control. The pseudoplastic properties of PEO solutions reduce mist formation during spraying of aqueous solutions that contain PEO. This property is used in metal-working fluids to lower worker exposure to mists from the cutting and grinding aids. PEO may also be used to focus the spraying area of herbicides and water-based coatings. 

Uses Surfactant, film-former in metalworking applies., esp. for aluminum cutting and grinding and in fiber and plastic lubrication Features Reacts readily with alkalinity sources, making it easily incorporated into water-based fluids when exposed to temps, common in metal-forming operations, its film-forming props, reduce heat and improve tool life Properties SI. yel. cl. liq. sp.gr. 1.018 vise. 510 cp pH 2.4 (10%) 3.79% P UseLevei 1-15%... 

The highest G-ratios are obtained when grinding with straight oil coolants. Such oils reduce power, increase maximum depth of cut, and produce smoother finishes. Disadvantages include inabiUty to remove heat from the work, oil mist in the work area, fire hazard, and tendency to hold grinding swarf (fine metal chips and abrasive particles produced in the grinding process) in suspension. Reference 51 is an excellent survey article for grinding fluids. 

Uses Oil emulsifier for conventional and heavy-duty sol. cutting fluids Features Highly cone. blended 15% with a base oil to produce an emulsifiable oil for general machining and grinding of ferrous and nonferrous metals compat.
