摘要:
A machine tool (1) equipped with a supporting body (5) and at least one tool-holder spindle (6), rotatable about a respective axis (A1), also has a built-in dust extraction device (8) comprising an extractor hood (9) located in close proximity to the spindle (6) and presenting a suction port (10) positionable near to a machining area (11), so as to extract chips and dust generated in the course of machining operations; the hood (9) is capable of movement along a direction (D1) parallel to the axis (A1) of rotation, extended and retracted by the action of respective translating members (19) operating in conjunction with sensors (34) able to read the profile of a workpiece (7), in such a way that the suction port (10) can be positioned to best advantage.
摘要:
A machine tool having a cutting unit moved longitudinally, characterized by comprising a bed (1) having right and left side-parts (4) on which longitudinal guide rails (7) are formed, respectively, a cutting unit (2) which is installed supportedly across the guide rails, moved longitudinally, and forms a cutting part (11) on its front side, and a work fixing table (3) installed fixedly integrally with a bed, wherein a cover device (14), which has cover surfaces for surrounding the upper and right and left side surfaces of the cutting part and forms a machining space opened only downward due to a relation between the cover surface, and the work fixing table and cutting unit, is provided between the cutting unit and the work fixing table, and the right and left side surface parts of the cover surfaces of the cover device are suspended to a position lower than the guide rails inside the right and left side parts of the bed, whereby cutting chips can be prevented from scattering onto the right and left guide rails by the cover device.
摘要:
2.1 Die in einem Mauerwerk einzusetzenden Spreizdübel können in Bohrlöcher mit Hinterschneidung formschlüssig eingesetzt werden. Zur Herstellung einer solchen Hinterschneidung wird ein Bohrer (1) verwendet, dessen Bohrplättchen (15) über den Bohrschaft übersteht, so daß durch eine Schwenkbewegung des Bohrers (1) die Hinterschneidung entsteht. 2.2 Um einen definierten Schwenkbereich und damit definierte Hinterschneidungen zu erhalten, ist eine dem Bohrschaft umschließende Führungshülse (2) vorgesehen, welche vorzugsweise eine konische Innenfläche (10) besitzt. Die konische Innenfläche begrenzt den Schwenkbereich des Bohrers (1).
摘要:
To connect electrical supply leads (19) to an electrical distribution track (1-6) a hole (16) is formed in a rear wall (2) by drilling a series of intersecting holes using a guide block (7) engageable in the track channel and including at a locking plate (19) to secure it therein, inserting an insulating bushing (8) into the hole (16) and feeding the supply connectors (19) through the bushing for connection to a supply connector (21) which is inserted into the track through the channel mouth.

摘要:
A drill guide for use with an orthopaedic drilling device includes a base and a sleeve movably coupled to the base. The base can be coupled to a surgically-prepared surface of a patient's bone and includes cylindrical body defining a passageway through it and a pin coupled to the body. The sleeve includes a slot and the pin of the base is received through the slot of the sleeve.
