Abstract
Processing, such as grinding or cutting, in a cold air blast is performed at low temperature with higher precision and higher efficiency in a pollution-less situation, wherein a conventional processing fluid is not applied. A compressed dry cold air of a temperature of minus 30.degree. C. or lower is blasted to a processing spot during processing, while a pollution-less fine mist of an oil, such as Accu-Lube, is supplied to the surface of a grinding stone in a small amount, or with a processing tool which has been treated in a fixed lubrication treatment. The apparatus includes a cooler for cooling a temperature of a filtered, compressed, dry air to minus 1.degree. C. or lowers a cold air blasting unit for supplying the cooled dry air to a processing spot, and a device which supplies a mist of a pollution-less oil, such as a vegetable oil or the like, to the processing spot directly or indirectly by the help of the processing tool.
