摘要:
Die Erfindung betrifft einen Kühlkörper aus Metall, vorzugsweise aus einem massiven Metallblock, insbesondere aus Aluminium, sowie ein Verfahren und ein Werkzeug zur Herstellung desselben. Der Kühlkörper weist eine Mehrzahl von durch zwischen ihnen angeordnete Kühlkörperrippen (26) voneinander getrennten, nebeneinander angeordneten sowie parallel verlaufenden Fluidleitungen (32) zum Durchleiten von Kühlfluid auf. Er ist dadurch gekennzeichnet, dass die Fluidleitungen (32) durch Nuten (24) gebildet sind, die in das Metall eingefräst sind.

Provided is a router guide (100) that comprises: a guide part that has a first through-hole (11) and a guide surface (12) that guides a cutting tool attachment part (220) of a router device (200) along the first through-hole (11); a maintaining part (20) that maintains the position of the guide surface (12); and a positioning part that positions the guide part. The guide surface (12) is formed such that, in a state where the maintaining part (20) is in contact with a surface (300a) of a composite material (300), the distance from the surface (300a) becomes smaller as the guide surface approaches a second through-hole (31). The guide part is formed so as to be elastically deformable. In a case where the guide part is caused to elastically deform along the surface shape of the composite material (300), the maintaining part (20) maintains the position of the guide surface (12) with respect to the surface (300a) at a position that corresponds to the surface shape.

Die Erfindung betrifft ein Verfahren zum Aufrauen einer, insbesondere planen und/oder gehärteten, Stirnseitenfläche eines im Wesentlichen rotationssymmetrischen Bauteils, insbesondere einer Stirnseitenfläche eines Zahnrads, wobei eine erste Halte- und Antriebseinrichtung (55) vorgesehen ist, mittels der das Bauteil (5) um seine zentrale Bauteil-Symmetrieachse (Az) drehbar gehaltert und mit einer definierten Drehzahl drehangetrieben wird, wobei eine zweite Halte- und Antriebseinrichtung (57) vorgesehen ist, mittels der ein Schneidwerkzeug (59) um eine Werkzeug-Drehachse (A w ) drehbar gehaltert und mit einer definierten Drehzahl drehangetrieben wird, wobei das Schneidwerkzeug (59) derart relativ zu dem Bauteil (5) angeordnet wird, dass die Werkzeug-Drehachse (Aw) und die Bauteil-Symmetrieachse (A z ) im Wesentlichen parallel zueinander angeordnet sind, insbesondere mit einem definierten Abstand voneinander beabstandet sind, und mittels des drehangetriebenen Schneidwerkzeugs (59) eine Aufraustruktur (43) in einen die aufzurauende Stirnseitenfläche (23, 27) bildenden, insbesondere radial äußeren und/oder exzentrischen, Wandbereich (39, 41) des ebenfalls drehangetriebenen Bauteils (5) eingeschnitten und/oder eingefräst wird.
摘要:
A reverse acting rupture disc and methods of forming the same are provided. Generally, the rupture disc comprises a bulged portion and a circumscribing flange area surrounding the bulged portion. The bulged portion includes a mechanically formed line-of-opening recess comprising a singular channel. In certain embodiments, the mechanical process by which the recess is formed utilizes a high-speed mill which removes a portion of metal from the bulged portion of the disc without disrupting the substantially uniform metallic grain structure of the metal adjacent the channel.

The invention relates to a groove cutting tool (10) comprising a body (12) and a holder (13 wherein the holder (13) is slidably mounted in the body (12). The, holder (13) having a first end at which a blade (16) is mounted and a second end, distal in a slidable direction (15) of the holder (13), from the first end. A drive pinion (20), located towards the second end, is configured to be in rotational communication with the blade (16).
摘要:
A fluting method for forming a flute in a workpiece while the workpiece is moved relative to a rotating tool by the combination of a rotating feed shaft with other feed shafts, the method comprising a machining process of relatively moving the rotating tool on a tool path that runs along the direction in which the flute extends and machining the workpiece using a rotating tool with a diameter that is smaller than the width of the flute. The machining process changes the relative position of the rotating tool with respect to the workpiece and performs machining multiple times so that the rotating tool makes internal contact with a circle that has the width of the flute being formed in the workpiece as the diameter.
摘要:
A control device for a machine tool for machining a workpiece while orbital movement is performed for causing an auto-rotating rotary tool to move in a circular manner, the control device comprising: a reading and interpreting unit for reading a machining program containing input information; and a computing unit for combining a first tool pathway along which a rotary tool travels and which has been set on the basis of input information about the travel of the rotary tool, and a second tool pathway along which the rotary tool orbits and which has been set on the basis of input information about the orbital movement, and for setting a third tool pathway along which the rotary tool travels in a machining shape while moving in an orbital manner.
