Abstract
A method of fabricating articles, such as an oxide ceramic article, is disclosed. The method includes cutting an oxide ceramic workpiece in a cutting zone and applying a cutting fluid to the cutting zone. The cutting fluid includes an aqueous solution which contains a sufficient amount of a boron compound to effectively provide lubrication. The boron compound is selected from the group consisting of boric acid, alkali metal borates, aluminum borate, and mixtures thereof. A method of fabricating articles, which includes cutting a workpiece in a cutting zone with an oxide ceramic cutting point and applying a cutting fluid to the cutting zone is also disclosed.
Claims27
A method of fabricating an oxide ceramic article comprising cutting an oxide ceramic workpiece in a cutting zone, and applying a cutting fluid which includes an aqueous solution containing a sufficient amount of a boron compound to effectively provide lubrication to the cutting zone, wherein the boron compound is selected from the group consisting of boric acid, boric oxide, alkali metal borates, alkaline earth metal borates, aluminum borate, and mixtures thereof, wherein said aqueous solution is substantially free of organic compounds.
A method of fabricating a ceramic workpiece comprising:
- turning, milling, or drilling an oxide ceramic workpiece with at least one cutting point;
- and
- applying a cutting fluid, which is an aqueous solution of boric acid, said solution being substantially free of organic compounds, to the workpiece and the cutting point.
A method of fabricating a steel article comprising cutting a steel workpiece in a cutting zone with at least one oxide ceramic cutting point, and applying a cutting fluid which includes an aqueous solution containing a sufficient amount of a boron compound to effectively provide lubrication to the cutting zone, wherein the boron compound is selected from the group consisting of boric acid, boric oxide, alkali metal borates, alkaline earth metal borates, and mixtures thereof, wherein said aqueous solution is substantially free of organic compounds.
A method of fabricating an oxide ceramic article comprising cutting an oxide ceramic workpiece in a cutting zone, and applying a cutting fluid consisting essentially of water and a sufficient amount of a boron compound to effectively provide lubrication to the cutting zone, wherein said boron compound is selected from the group consisting of boric acid, boric oxide, alkali metal borates, alkaline earth metal borates, aluminum borate, and mixtures thereof.
A method of fabricating a ceramic workpiece comprising:
- turning, milling, or drilling a ceramic workpiece with at least one cutting point;
- and
- applying a cutting fluid consisting essentially of water and boric acid to the workpiece and the cutting point.
A method of fabricating a steel article comprising cutting a steel workpiece in a cutting zone with at least one oxide ceramic cutting point, and applying a cutting fluid consisting essentially of water and a sufficient amount of a boron compound to effectively provide lubrication to the cutting zone, wherein the boron compound is selected from the group consisting of boric acid, boric oxide, alkali metal borates, alkaline earth metal borates, and mixtures thereof.
