method of introduction of polymer-containing lubricant-cooling agent into cutting zone

摘要

A method of introduction of a polymer-containing lubricant-cooling agent into cutting zone, at which polymer melt is put on the workable surface. For working the lubricant-cooling agent is created in the form of a fluidised bed of the powder of polymer in cold gas, into which at putting on the workable surface hot gas flow is introduced with a temperature higher than the melting point of polymer.
