Abstract

The present invention is directed to a method for machine optical quality finishes and contour accuracies of workpieces of carbon-containing metals such as steel with diamond tooling. The wear rate of the diamond tooling is significantly reduced by saturating the atmosphere at the interface of the workpiece and the diamond tool with a gaseous hydrocarbon during the machining operation. The presence of the gaseous hydrocarbon effectively eliminates the deterioration of the diamond tool by inhibiting or preventing the conversion of the diamond carbon to graphite carbon at the point of contact between the cutting tool and the workpiece.

Method for machining steel with diamond tools

Patent Casstevens, J.M.

This patent describes a method for decreasing the wear rate of a diamond cutting tool used in machining a steel workpiece. This method consists of providing a gaseous hydrocarbon atmosphere at the interface between the cutting tool and the workpiece during the machining of the latter with the concentration of gaseous hydrocarbons being adequate to inhibit the conversion of diamond carbon to graphite carbon at the point of contact of the diamond tool with the workpiece.
Method for machining steel with diamond tools

Patent Casstevens, John M. (Greenville, TX)

The present invention is directed to a method for machining optical quality inishes and contour accuracies of workpieces of carbon-containing metals such as steel with diamond tooling. The wear rate of the diamond tooling is significantly reduced by saturating the atmosphere at the interface of the workpiece and the diamond tool with a gaseous hydrocarbon during the machining operation. The presence of the gaseous hydrocarbon effectively eliminates the deterioration of the diamond tool by inhibiting or preventing the conversion of the diamond carbon to graphite carbon at the point of contact between the cutting tool and the workpiece.

Diamond tool machining of materials which react with diamond

Patent Application Lundin, R.L.; Stewart, D.D.; Evans, C.J.

This invention is comprised of an apparatus for the diamond machining of materials which detrimentally react with diamond cutting tools in which the cutting tool and the workpiece are chilled to very low temperatures. This chilling halts or retards the chemical reaction between the workpiece and the diamond cutting tool so that wear rates of the diamond tool on previously detrimental materials are comparable with the diamond turning of materials which do not react with diamond.
