Abstract
A process for treating cutting tools to extend the useful duty cycles of the tools by immersing the tools to be treated in a bath of a solvent in sufficient amounts and at a temperature to remove contamination from the surface of the tools and to coat the tool surfaces with perfluoroethylene. The solvent and perfluoroethylene resin are circulated throughout the immersed tools for a time sufficient to coat the surfaces with polyfluoroethylene resin.
Claims9
A process for treating a cutting tool, comprising the steps of:
- a) placing the tool to be treated into a first bath of solvent;
- b) heating the bath of solvent to remove contaminant from the surfaces of the tool within the bath of solvent;
- c) placing the tool in a second bath of a perfluoroethylene resin;
- d) circulating the second bath of perfluoroethylene resin for a time sufficient to coat the surfaces of the tool with perfluoroethylene resin;
- and
- e) removing the tool from the second bath to permit the tool to return to ambient temperature.
