Method for grinding side portion of stacked hard, brittle material substrate

An elastic abrasive with abrasive grains dispersed in or adhered to an elastic base material is ejected toward a side portion of a substrate together with compressed air. The elastic abrasive is ejected toward a predetermined processing area centered on a processing point in an ejection direction that intersects a widthwise line at the processing point and that forms a predetermined inclination angle selected from a range of 2° to 60° relative to a contact line. Moreover, an ejection nozzle and the workpiece are moved relatively to each other so that the processing area is moved at a fixed speed in a circumferential direction of the workpiece and so that the ejection direction is maintained at each processing point after moving. If multiple stacked substrates are to be processed, the processing area is moved at a fixed speed also in a widthwise direction of the substrates.

Orifice for a waterjet cutter

An orifice for a high-pressure waterjet cutter includes a first surface defining an inlet plane, a second surface defining an outlet plane, and an inner bore aligned along a flow axis and extending from the first surface to the second surface. The orifice also includes a first layer of polycrystalline diamond extending from the first surface to a plane between the inlet plane and the outlet plane, and a second, separate layer of polycrystalline diamond extending from the plane to the second surface. The first layer and the second layer are coupled to one another to define a single component. The second layer has material properties different than the first layer.

METHOD FOR PRODUCING A GLASS SUBSTRATE WITH AN EMBOSSED SURFACE FINISH AND GLASS SUBSTRATE OBTAINED USING SAID METHOD
20210387308 · 2021-12-16 ·

The invention relates to a method comprising the steps of: Abrasion, preferably but non-limited by means of sandblasting which produces mechanical roughing on the surface of the glass substrate, optionally applying a primer on the roughed surface, and applying an ink on this primer by means of screen printing which may be digital inkjet screen printing, drying the injected ink deposited by means of digital screen printing, and performing a tempering process. A glass substrate with an embossed surface finish is achieved which simulates the aesthetic and surface texture of different construction materials, such as stone, wood, granite, marble or porcelain, among others.
