摘要:
A remote controlled actuator includes an elongated spindle guide section (3) and a distal end member (2) fitted to a distal end thereof for alteration in attitude. The distal end member rotatably supports a spindle (13) for holding a tool (1). The spindle guide section includes a rotary shaft (22) for transmitting rotation of a tool rotation drive source (41) to the spindle. An attitude altering member (31) inserted in a guide hole (30a) is selectively advanced or retracted by an attitude control drive source (42). An initial attitude hold control unit (53a) controls the attitude control drive source so that an initial attitude holding force (F0) necessary to maintain the distal end member in the initial attitude can be applied to the attitude altering member. An attitude alteration control unit (53b) controls the attitude control drive source so that the attitude of the distal end member can be altered by a force (F5) larger than the initial attitude holding force.

A tool holder and rotating spindle of a milling machine is provided. A dampening member may be disposed on an outer surface of the tool holder or spindle or between the tool and tool holder or tool holder and spindle to mitigate harmonic resonance attributable to the use of the tool holder with the cutting tool.
摘要:
The angular transfer device (1) with pivoting support (2) with two or four wheels (3), is a universal accessory for numerically controlled machines having at least four controlled axes, x, y, z, c. It finds its major use in those processing fields concerning milling and engraving on materials having a flat surface slab, such as slabs of glasses, mirrors, marble, granite, metals and the like. It allows the execution of millings and engravings in their different finishing stages (raw, satin-finished, semi-polished, polished), with no need of interrupting the processing to change the tool, as opposed to what happens today. Unlike the angular transfers of the prior art, which have only one wheel, this device is able to house in the same angular transfer even two or four differently grained wheels (3) on a pivoting support (2), each one of which, at the proper time, is operated by a little piston (10) which, causing the pivoting movement of the support (2), causes the wheel to process for the specific finishing stage it has been choosen for. Thanks to this, it is no longer necessary to change the tool for each finishing stage that is intended to obtain, since the programmed impulse of the piston (10) is sufficient to select immediately the wheel (3) which is already available in the angular transfer (1). The device subject of this application is also provided with a special tracer point (4) with truncated pyramid gaps in plastic scratch-resistant material, able to execute uniform engravings even on irregular surfaces, ensuring the same depth on the whole engraved length. Depth is adjustable.

Die Erfindung betrifft ein einwechselbares Werkzeugaggregat (1) zum Bearbeiten von Werkstücken, die bevorzugt zumindest abschnittsweise aus Holz, Holzwerkstoffen, Kunststoff oder dergleichen bestehen, mit einer Werkzeugaufnahme (2) mit einem Hohlraum (2') zum Aufnehmen von Bearbeitungswerkzeugen (4) bzw. Werkzeugadaptern (6), wobei die Werkzeugaufnahme (2) in Bezug auf einen Grundkörper (8) des Werkzeugaggregats um eine erste Achse (C) drehend antreibbar und bevorzugt um eine hiervon abweichende, zweite Achse (A) verschwenkbar ist, einer Schnittstelle (10) zum Einwechseln des Werkzeugaggregats in eine Schnittstelle einer Spindeleinheit, und mindestens einem bewegbar, insbesondere verschiebbar gelagerten Halteelement (12) zum Halten von Bearbeitungswerkzeugen (4) bzw. Werkzeugadaptern (6) in der Werkzeugaufnahme (2). Das erfindungsgemäße Werkzeugaggregat ist dadurch gekennzeichnet, dass das Werkzeugaggregat einen ersten Druckfluidkanal (20) aufweist, der mit dem Hohlraum (2') der Werkzeugaufnahme (2) in Verbindung steht und in dem Hohlraum (2') in einem Anlagebereich (22) mündet, in welchem ein Bearbeitungswerkzeug (4) bzw. Werkzeugadapter (6) im gespannten Zustand anliegt.
摘要:
A cutting tool device for a machine tool having a cutting tool (2) for cutting a plane fixed to the tip end of a rotating shaft (1) and provided with a suction cover (10) covering airtightly the surrounding portions except for a tip face (a), of the cutting tool (2), wherein a hood (19) is attached to the tip opening edge of the suction cover (10) so as to further extend forward therefrom and to be displaceable longitudinally within a limited range, and an urging means (24) for urging the hood (19) forward is provided, whereby chips (w1) produced by the cutting tool (2) can be positively sucked and discharged when the tool is used in any of a roughing step and a finishing step.
摘要:
A tool holder (10) for use in a rotating spindle (12) of a milling machine. The tool holder (10) comprises a conically tapered shank portion (14) for insertion into the spindle (12) and a cutting tool mounting portion (18). Disposed between the shank (14) and mounting portions (18) is a flange portion (34). Additionally, extending about the shank portion (14) is a dampening member (38). The dampening member (38) is compressible between the flange portion (34) and the spindle (12) when the tool holder (10) is inserted into the spindle (12), and is adapted to eliminate harmonic resonance attributable to the use of the tool holder (10) with an extended shank cutting tool (30).
摘要:
An apparatus and method for balancing a high speed rotary tool assembly (1) is provided. The apparatus includes a rotary tool holder (3) having an axis of rotation (11), a cutting tool retainer (13) in the rotary tool holder (3) having a lockring (23) that circumscribes the axis of rotation (11) of the holder (3), and a pair of axially spaced balancing rings (35a, 35b) for balancing the entire rotary tool assembly (1) which are rotatably mounted around bearing surfaces (37) circumscribing the lockring (23) so as to be angularly positionable around the axis of rotation (11) of the tool holder (3). In the method of the invention, the unbalance of the tool holder (3) and cutting tool (17) is determined, and then the rings (35a, 35b) are rotatably adjusted about the bearing surface (11) on lockring (23) to create an unbalance which cancels out the determined unbalance of the tool holder (3) assembly.

A milling machine 10 comprises a machine body 12 having a lower limb 14. The lower limb 14 is provided with four bearing blocks 16 which engage two slide rails 18 fixed vertically to the machine body, and is also provided with a pair of slide rails 20 fixed adjacent the top edge thereof. A cross-slide 22 slides on rails 20 by means of similar bearing blocks, and a work table 24 is located above the cross-slide 22 and is slidable therealong by means of rails 26 fixed to the underneath of the table, which rails 26 are slidable on bearing blocks 28 fixed to the cross-slide.
