Chattering suppression apparatus (10) comprises multiple bolt members (24a through 24d) for mounting boring bar (20) in the spindle (18). Inside the main body configuring bolt members (24a through 24d), a damper chamber (34) is formed and, inside the damper chamber (34), a friction damper section (36) that suppresses the vibration energy that can cause chatters during machining operation of workpiece W, through sliding friction, is housed in the movable state.

A method and apparatus for automated loading and unloading of a cylinder (14) in an engraver (10). The method and apparatus permit the engraver (10) to accommodate cylinders (14) of differing geometries, including a range of lengths, diameters and mounting configurations. The engraver (10) comprises a headstock (16) and a tailstock (18) which cooperate to rotatably support a cylinder (14) at an engraving station (15) in the engraver (10). The engraver (10) also comprises a cylinder handling system having at least one cylinder support (30) for supporting the cylinder (14) between the headstock (16) and tailstock (18) during loading and unloading of the cylinder (14). The cylinder handling system comprises a driver (32) for driving the cylinder support (30) towards and away from the engraving station until the headstock (16) and tailstock (18) engage and rotatably support the cylinder (14). Once the cylinder (14) is rotatably supported between the headstock (16) and tailstock (18), then the cylinder support (30) is retracted. Each cylinder support (30) comprises a telescoping support member (34) having a support nest (36) for engaging and supporting the cylinder (14) at the engraving station (15).

Le procédé de fraisage, assisté par laser consiste, en cours de fraisage d'une pièce mécanique, à diriger au moins un faisceau laser sur la pièce juste en amont de l'outil de fraisage de manière à chauffer au moins une zone de la pièce parallèle à un profil de coupe prédéterminé, puis à déplacer le faisceau laser longitudinalement sur la pièce dans le même sens et à la même vitesse Vf que la vitesse d'avance de l'outil de fraisage sur la pièce. La zone chauffée peut être une première étape et/ou une deuxième zone critique (12, 13) située juste en amont respectivement des points d'entrée et de sortie de l'arête de coupe de l'outil de fraisage dans la pièce. La zone chauffée peut également être une zone (14) de largeur égale à la largeur de la zone de coupe.
摘要:
The suction device described comprises an enclosure, which surrounds the workpiece (3) to form a suction chamber (10), and a suction unit connected via a channel (7) to the suction chamber (10). In order to produce in the suction chamber (10) a suction-air stream which is as constant as possible and which covers the whole area in which residues arise, the suction channel (7) is annular in design, surrounds the suction chamber (10) and is attached to the frame of the machining equipment.
摘要:
The vibration level (A) is measured and applied to a controllable filter (F). The filter (F) is a band pass filter that only passes a narrow band around a certain frequency that is determined by the frequency (f) of the machining cycle. The output signal of the filter is then compared to one or several reference levels (7) and an alarm signal is outputted in case of unacceptable deviation from the reference level.
摘要:
A cutting tool includes a shaft extending along a rotation axis and having a first end portion and a second end portion, and a sensor device disposed in such a manner as to surround a portion of the shaft in a longitudinal direction of the shaft. The cutting tool is configured to cut a workpiece by rotating around the rotation axis of the shaft. The sensor device includes a sensor module including a plurality of first sensors configured to detect a first physical quantity of the shaft, a substrate electrically connected to the first sensors, and a wireless communication unit electrically connected to the substrate and configured to transmit a signal including information of the first physical quantity detected by the first sensors to outside and a housing accommodating the sensor module. A region of the shaft surrounded by the sensor device includes a first region having a shape of a 4n-sided polygon when viewed from a direction in which the rotation axis extends. The n is a natural number of two or more. When viewed from the direction in which the rotation axis extends, the plurality of first sensors are arranged on at least two of outer peripheral surfaces of the first region, each of the outer peripheral surfaces of the first region corresponding to one of sides of the 4n-sided polygon, perpendicular lines of the at least two outer peripheral surfaces passing through the rotation axis and intersecting each other at 90 degrees.
摘要:
Die Erfindung betrifft eine Vorrichtung (1) zur Führung und Auslenkung eines Bohrfräsers (2) zur Herstellung eines hinterschnittenen Bohrlochs. Durch Drehung eines Exzenters (10) in einer Exzenteraufnahme (9) lässt sich der Bohrfräser (2) auslenken und durch Drehung der Exzenteraufnahme (9) mit ausgelenktem Bohrfräser (2) eine Hinterschneidung in dem Bohrloch herstellen. Eine Drehwinkelbegrenzung (24) begrenzt einen Drehwinkel des Exzenters (10) in der Exzenteraufnahme (9) derart, dass bei einem Drehantrieb des Exzenters (10) zunächst der Bohrfräser (2) ausgelenkt und anschließend die Exzenteraufnahme (9) mit dem Exzenter (10) gedreht wird.
摘要:
A cutting tool is rotatable about an axis line, and includes a main body portion, a cutting insert, and a plurality of anti-vibration members. The main body portion has an inner circumferential surface and an outer circumferential surface opposite to the inner circumferential surface. The cutting insert is attached to at least one of the inner circumferential surface and the outer circumferential surface. Each of the plurality of anti-vibration members is provided at the main body portion. Each of the plurality of anti-vibration members includes a weight member composed of a material having a specific gravity larger than a specific gravity of a material of the main body portion.
