摘要:
Eine Vorrichtung mit einem Bearbeitungswerkzeug (52) zur Bearbeitung von Rollen (40) mit starker Krümmung, die sich während der Bearbeitung drehen, enthält zwei Führungsscheiben (12, 38) und eine Stützscheibe (18), die drehbar gelagert sind. Die Führungsscheiben (12, 38) umgeben die Rolle (40) in einer Bearbeitungsposition (A) beiderseits und symmetrisch zu einer durch die Mitte (43) der Rolle (40) verlaufenden Querachse (43). Jede Führungsscheibe (12, 38) besteht aus zwei Teilscheiben (46), die die Rolle (40) außermittig mit ihren Mantelflächen (48) berühren, die an die Rolle (40) angepaßt sind. Die Stützscheibe (18) ragt in die Lücke zwischen den Teilscheiben (46) hinein und läßt sich in eine dem Bearbeitungswerkzeug (52) abgewandte Stellung verschieben.

Vorrichtung zur Endbearbeitung einer Umfangsfläche (2) eines wellenförmigen Werkstückes (1), umfassend eine Antriebseinrichtung zur Erzeugung einer Rotationsbewegung des Werkstückes (2) und eine Andrückeinrichtung (3) zum Andrücken eines Werkzeuges (4) an die Umfangsfläche (2) des rotierenden Werkstückes (2), wobei das Werkzeug (4) mit einer Bearbeitungsfläche (5) an der Umfangsfläche (2) anliegt und die Umfangsfläche (2) eine erste Profilform aufweist, dadurch gekennzeichnet, dass die Bearbeitungsfläche (5) Bereiche (6, 7) unterschiedlicher Schnittigkeit aufweist, wobei eine räumliche Verteilung der Schnittigkeit eine nach der Endbearbeitung beabsichtigte zweite, von der ersten Profilform unterschiedliche Profilform der Umfangsfläche (2) vorgibt.
摘要:
Tools and methods for machining a dovetail 12 are disclosed. The dovetail 12 includes a plurality of tangs 15. In one embodiment, the tool 10 includes a body 20 and a plurality of mount brackets 30, each of the plurality of mount brackets connected to the body 20 and positionable in contact with a crush surface 32 of the dovetail 12. The tool 10 further includes an engagement member 60 connected to the body 20 and adjustable such that contact by the engagement member 60 with the dovetail 12 forces each of the plurality of mount brackets 30 against the associated crush surface 32. The tool 10 further includes a machining assembly 80 for machining one of the plurality of tangs 15 of the dovetail 12, the machining assembly 80 connected to the body 20.
摘要:
A method forthe manufacture of ceramic parts comprises using a centerless grinder has a cylindrical cutting grindstone (7) with a plurality of grooves (7a) formed on the cutting surface thereof, a cylindrical adjusting grindstone (8) disposed substantially parallelly to the cutting grindstone (7), and a blade (9) disposed between the cutting grindstone (7) and the adjusting grindstone (8), infeeding a round ceramic bar (10) to the centerless grinder, rotating the cutting grindstone (7) and the adjusting grindstone (8) in the direction of the round ceramic bar, thereby causing the grooves (7a) on the surface of the cutting grindstone (7) to grind the round ceramic bar (10).
摘要:
The invention concerns a method for machining a workpiece (1) by a grinding machine, comprising the step of rotating and translating the workpiece along a first axis (4) toward the first abrasive wheel; rotating an abrasive wheel (6) around a second axis (61) and translating it along a third axis (62) such that the abrasive wheel grinds a peripheral portion (103) of the workpiece; the abrasive wheel being positioned in a position in translation along the third axis; and wherein the position in translation is determined as a function of a position and of an angular position of the workpiece around the first axis. The invention further related to a grinding machine for carrying out such method.
摘要:
A broach or other tool having a plurality of cutting teeth along its length is produced by simultaneously grinding a plurality of preformed cutting teeth having oversize dimensions, such as oversize outer diameters, using a rotating dressed generally cylindrical grinding wheel engaging the oversize teeth along a length of the broach preform to impart reduced final print dimensions such as final outer diameters to the oversize teeth. Outer diameters which increase from one tooth to the next and outer diameters which remain constant for several adjacent teeth can be simultaneously ground. Different clearance angles can also be imparted during the grinding operation.
