摘要:
The present invention discloses a wheel (100) for grinding edge of a glass substrate and method of manufacturing of the same that does not require profiling work and improves grinding speeds by stabilizing quality of processed edge with uniformly arranged abrasive particles (21) and adjusting exposure degree of abrasive particles (21). A metal binder (23) is applied to a groove (12) along the centre part of the grinding face forming the circumference of the disk and the abrasive particles are partially buried into the metal binder (23). The plurality of abrasive particles (21) are arranged at the crossing points of columns and rows with regular intervals. For this, a pattern plate (30) with holes (31) is used at the crossing points of columns and rows with regular intervals on the metal binder (23).

An interior rearview mirror assembly includes a mirror casing and a prismatic reflective element. The mirror casing is a unitarily molded mirror casing having at least one attachment surface. The prismatic reflective element includes a glass substrate having a front surface and a rear surface and a perimeter edge about a periphery of the glass substrate. A mirror reflector is established at the rear surface of the glass substrate. The perimeter edge of said glass substrate has a generally rounded surface disposed between the front surface and the mirror casing. The prismatic reflective element is attached at the attachment surface of the mirror casing. The perimeter edge of the glass substrate is exposed to and is viewable by the driver of the vehicle when the interior rearview mirror assembly is normally mounted in the vehicle.
摘要:
Die Erfindung betrifft ein Verfahren zur Reparatur von sichtbaren Fehlern in der Oberfläche von Glasscheiben, insbesondere in Frontscheiben von Kraftfahrzeugen und eine dazugehörige Anordnung. Sie ist besonders geeignet, Fehler in Glasscheiben, insbesondere in Frontscheiben von Kraftfahrzeugen, die durch Steinschlag entstanden sind, wirkungsvoll zu beheben. Die Aufgabe der Erfindung ist es daher, ein Verfahren zur Reparatur von sichtbaren Fehlern in der Oberfläche von Glasscheiben, insbesondere in Frontscheiben von Kraftfahrzeugen vorzuschlagen, mit dem es möglich ist, diesen Fehler so zu beseitigen, dass nach der Reparatur weder optische noch mechanische Mängel nachweisbar sindwird gelöst, indem im Bereich um die Schadstelle so viel Glasmaterial abgetragen, dass eine Ausnehmung mit einer regelmäßig geformten geometrischen Struktur entsteht. In die entstandene Ausnehmung wird ein Glaskörper mit mindestens einer planen Oberfläche, der in seiner geometrischen Struktur mit dieser Ausnehmung identisch, ist eingesetzt.
摘要:
The machine (1) for grinding plate-shaped elements, particularly tiles and slabs of ceramic material, natural stones, glass or the like, comprises: a base frame (2); forward movement means (3) for at least a plate-shaped element (4) having at least a first side (5) to be ground and at least a second side (6) transversal to the first side (5), the forward movement means (3) being fitted on the base frame (2) and being suitable for moving the plate-shaped element (4) on a movement surface (8) along a direction of forward movement (A); machining means (20, 21) for the first side (5), which are arranged in proximity of the movement surface (8) and are suitable for intercepting the plate-shaped element (4) in its movement along the direction of forward movement (A), the machining means (20, 21) comprising at least one between a side grinding wheel (20) and a chamfering wheel (21); and square positioning means (32, 33, 34, 35) of the plate-shaped element (4) on the movement surface (8), which comprise: - a first pusher (32) and a second pusher (33) moving alternately along the direction of forward movement (A) and are suitable for pushing the second side (6) to place it in a squared-up position substantially at right angles to the direction of forward movement (A); a first linear actuator (34) suitable for operating the first pusher (32) and a second linear actuator (35) suitable for operating the second pusher (33), the linear actuators (34, 35) being separated and independent the one from the other and electronically connected to a processing and control unit (16) suitable for controlling their relative movement.
