Abrading aid containing paraffin and an inhibitor
Abstract
Abstract A direct externally applied grinding, abrading and cutting aid for tools which includes a vehicle or carrier of a suitable matrix softer than the cutting material and which will readily adhere thereto without chipping while the tool is in motion. Dispersed within the matrix is a halogen salt or the like which includes hydrocarbons, chlorides, fluoborates, fluorides and various sulfides. These materials were selected on the basis that they sublime or decompose at temperatures below those that would metallurgically damage the metal workpiece. This aid is applied directly to the tool, as for example, to a coated abrasive and may be reapplied as often as is necessary, thus increasing both the life of the tool, its cutting rate, total metal removal, and its efficiency in addition to lowering the temperature of the material being cut. In addition, there is disclosed an automated system for maintaining the workpiece at a selected temperature through the controlled application of the aid.
