Embodiment

[0082] 1. Cutting disc with 110 grooves and sharp cutting edges using finely ground cobalt bonded sintered diamond

[0083]Cutting disc blanks shaped according to the prior art with continuous peripheral ridges were prepared using finely ground, cobalt-bonded sintered diamond. The size of the diamond particles used is substantially less than 1 micron. A plate of this material was first ground to a thickness of 0.6 mm, then EDM was used to cut a cylinder with a central hole, then, on each of these cylinders, at the intersection of the peripheral ridges Tapered or inclined tapered areas with a total included angle of 125° are ground on both sides of the surface. The radius of curvature at the intersection is substantially less than 1 micron. The cutting disc blank had a center hole of 0.8 mm and a diameter of 2.0 + / - 0.02 mm. Five of these disks, formed according to the prior art, were cleaned to remove adhering dust and contaminants and were subsequently mounted on shafts ha...

Abstract

A cutting disk is provided for. forming a scribed line on a surface of a body or object. The cutting disk comprises a disk shaped body (10) having a peripheral portion having first and second circumferentially extending tapered surfaces (18,20) that converge radially outwardly. The peripheral portion defines a scribing edge (22) with adjacent raised (30) and recessed (26) circumferentially extending cutting elements. A plurality of outwardly extending grooves (24) are formed in the first and second tapered surfaces (18, 20), and the outer ends of opposed- grooves (24) in the respective tapered surfaces (18, 20) being aligned to define between them the recessed (26) cutting elements. As a result, the scribing edge (22) defined by the cutting disk is a continuous sharp edge having alternating raised (30) and recessed (26) cutting elements, aligned circumferentially with one another. The cutting disk can be manufactured ' from sintered or cemented diamond grit, or other hard materials. Apparatus and a method for manufacturing the cutting disks' are also disclosed.

Description

Background technique [0001] The present invention relates to a scoring wheel or cutting disc which can be used to score lines on the surface of bodies or objects such as glass bodies, semiconductors, gemstones, crystalline material bodies or ceramic bodies . [0002] The cutting or scoring disk is typically supported by a spindle or shaft rotatably mounted to one end of a handle or another support member. Bringing the edge of the disc into contact with and moving relative to the surface to be scribed causes the cutting disc to roll over the surface, leaving a scribe line on the surface along which the object or body can be trimmed ground fracture. [0003] The cutting edge or edge of the scribe disk is urged to create cracks or grooves in the surface by applying a suitable force through the handle or support device. [0004] Such cutting discs can be used for glass products such as flat glass, window panes, bottles or jars. A particular application of this type of cutting ...
