Use of Water-Soluble Cutting Fluids

Use of water-soluble cutting fluids throughout the machining process... 

Some of the recently developed high-performance EP soluble oils have a cutting performance that almost matches that of additive-type neat oils, and they are particularly suitable for demanding operations in machine tools whose design allows the use of water-based fluids. 

Use A water-soluble antimicrobial agent for use in cutting fluids and other aqueous alkaline systems formaldehyde donor with controlled rate of release and minimum odor. 

Tool overhang should be kept to a minimum. Tools must be kept sharp to avoid buildup that can cause failure of the tool or the workpiece. A tool geometry similar to that used for cast iron is generally suitable. Liberal rake and clearance angles can be used. Cutting fluids are required to control the tool-tip temperature. Water-soluble cutting oils work well. 

Long or extended period batch treatments are occasionally performed on wells producing low water cut fluids (0 to 25% water). Oil-soluble or nearly oil-soluble inhibitors may be batched into the annulus. Usually half to one drum of chemical is used. The well fluids are circulated for two to four hours to mix the inhibitor into the annulus oil. The wells are then produced for a period of time (one month), when 37.8 to 56.7 liters (10 to 15 gallons) are again batched and the well circulated for two to four hours. With high fluid level wells this treatment has lasted for up to three months per batch. This procedure is a general guideline and the exact procedure should be supplied by tbe manufacturer.
