Embodiment Construction

[0010] Referring now to FIGS. 1 and 2, there is illustrated the diamond stone assembly, generally designated by reference numeral 2, having base assembly 2 made in accordance with the process of the invention. The base assembly 2 includes a lower plastic base on which a plate 6 is bonded in accordance with the invention. The plastic base 4 includes an upper wall 8 (FIG. 3) and four opposed upright longitudinal walls 10 and opposed upright lateral walls 12 to form cavity 14. A longitudinal rib 16 extends within the cavity and connects with a plurality of lateral rib segments 18.

[0011] The upper steel plate 6 is manufactured with oval holes 22 with conventional progressive punching equipment. The holes 22 are punched through the steel plate in lateral rows 22 in the pattern shown in FIG. 1 across a substantial portion of the steel plate except for the unpunched area 24. After the steel plate 6 is punched, it is de-burred and nickel-plated on its bottom to prevent any rust or oxidatio...

Abstract

A process for manufacturing the base of a diamond abrasive stone wherein a steel plate having a plurality of oval holes is bonded to a plastic base in a casting process so that plastic material is forced through the holes. Layers of nickel diamond material is applied to the surface of the steel plate.

Description

[0001] This application is a continuation of non-provisional application Ser. No. 10 / 686,032 filed Oct. 16, 2003.BACKGROUND OF THE INVENTION [0002] This invention relates to the fabrication of plastic members and more particularly to a process to manufacture the base for a diamond abrasive stone. SUMMARY OF THE PRIOR ART [0003] Abrasive stones are often affixed to a plate that is attached to a base such as formed from plastic. Many molding processes are employed in the prior art to fabricate the base supporting abrasives. It is known to apply abrasive stones through a metal plate affixed to the base, such as formed from plastic. Prior techniques, however, have been defective in providing optimum bonding between the plate and base, and do not provide a suitable low shrink rate. SUMMARY OF THE INVENTION [0004][0005] It is therefore, an objective of the invention to provide a process for fabricating the base of a diamond bench abrasive stone for sharpening knives and the like The proce...
