PROCESS FOR COOLING THE CUTTING ZONE OF MATERIALS BEING MACHINED AND A DEVICE FOR CARRYING OUT THE SAME

摘要

The process and device in question are used to cool the cutting zone of materials undergoing machining. In a process for cooling the cutting zone of a material being machined, a gaseous lubricating and cooling medium, treated in an ionizer in a corona discharge field, is directed onto the cutting zone at a rate equal to or greater than the rate of cutting. The corona discharge is produced using an adjustable stabilized electrical current which varies with the rate of feed of the gaseous lubricant/coolant. The device for carrying out this process comprises an ionizer (1) with a housing (7) which has an outlet nozzle (8) connected by the main line (9) to the source (3) of the gaseous lubricant/coolant, a corona electrode (2) mounted within the housing (7) and a power source (4) electrically connected to the corona electrode (2), and is provided with a regulator (5) connected to the main line (9) for the delivery of the gaseous lubricant/coolant, and a controllable stabilizer (6) for the output current which is incorporated into the power circuit of the corona electrode (2).
