Abstract:
A surgical device comprising: a handle assembly; a locking collar and a set of replaceable bits that load along an axis into the handle assembly; wherein the locking collar is fully removable from the handle assembly, the locking collar loads axially to a first position, and the locking collar rotates between the first position and a second position; wherein, in the first position, the locking collar is free to be axially removed from the handle assembly and the replaceable bits are free to be loaded or unloaded from the handle assembly; wherein in the second position, the locking collar is prevented from axial movement relative to the handle assembly and the replaceable bits are prevented from being received within, or removed from, the handle assembly.
Abstract:
An apparatus (200) for pneumatically amplifying the force acting upon a lock rod (95) to retain a toolholder (10) within a toolholder receiving member (65) has a spindle (205) extending from the toolholder receiving member and at least two in-line dual acting piston/cylinder modules (215) within a cavity within the bore (207) of the spindle. Each module (215) has a piston (220) within an associated cylinder (225) and wherein the lock rod (95), through a drawbar (230), is attached to the piston (220) of each module (215) such that when each module is pressurized, the combined force of all of the pistons is applied to the lock rod. The invention is also directed to a method for achieving this task.
Abstract:
Die Erfindung betrifft eine Wendeschneidplatte mit einer ersten und einer zweiten Plattenfläche (10a, 1 Ob), drei Seitenflächen (11 , 12, 13) und einem Schneidvorsprung (2), wobei der Schneidvorsprung (2) mindes- tens einen ersten und einen zweiten Schneidzahn (21 , 22) umfasst, an den Schneidzähnen (21 , 22) an einem Übergangsbereich zu der ersten bzw. der zweiten Plattenfläche (10a, 10b) Schneidkanten (31 , 32) ausgeformt sind, eine erste, der ersten Schneidkante (31 ) zugeordnete Span-Ablaufrichtung (A1 ) mit einer zweiten, der zweiten Schneidkan- te (32) zugeordneten Span-Ablaufrichtung einen Winkel bildet, der ersten und der zweiten Schneidkante (31 , 32) eine erste bzw. eine zweite Spanleitfläche (41 , 42) in Span-Ablaufrichtung zugeordnet sind, die Spanleitflächen (41 , 42) mindestens eine erste bzw. eine zweite Nut auf der ersten bzw. der zweiten Plattenfläche (10a, 10b) umfassen, die sich im Wesentlichen senkrecht zu der jeweiligen Span-Ablaufrichtung (A1 ) erstrecken. Die Erfindung betrifft weiter ein Werkzeug umfassend eine Wendeschneidplatte und ein Verfahren zur Herstellung derselben.
Abstract:
The disclosure is directed to a cutting tool assembly used for creating grooves in a microreplication tool. The cutting tool assembly includes a mounting structure and multiple diamonds aligned in the mounting structure to a tolerance of less than 10 microns. For example, first and second tool shanks having first and second diamond tips can be positioned in the mounting structure such that a cutting location of the first diamond tip is identical to a cutting location of the second diamond tip. However, the second diamond tip may be a defined distance further away from the mounting structure than the first diamond tip, or the second diamond tip may have a different shape than the first diamond tip. In this manner, the first diamond tip may cut a groove into a work piece and the second diamond tip may cut a sub-feature into the groove to create a multi-featured groove.
Abstract:
Es wird eine Werkzeugmaschine (1) und ein Verfahren zur Feinbearbeitung von Lagerbohrungen (6) einer Lagergasse (5) an mindestens einem Werkstück (4) gezeigt, bei dem ein von einem Werkstückhalter (2) gehaltenes Werkstück (4) und mindestens ein spanendes Werkzeug (7) relativ zueinander positioniert werden und dabei das Werkzeug (7) in das Werkstück (4) einfährt, und in einem weiteren Schritt simultan mehrere Lagerbohrungen (6) durch eine Relativbewegung zwischen mindestens diesem Werkzeug (7) und dem Werkstück (4) in Längsrichtung (9) der Lagergasse (5) feinbearbeitet werden. Um reproduzierbar eine hohe Feinbearbeitungsqualität samt kurzer Taktzeiten zu erreichen, wird vorgeschlagen, dass beim Positionieren mehrere in ihrer Lage zueinander und im Winkel fixierte Winkelköpfe (10) mit je einem spanenden Werkzeug (7) in das Werkstück (4) geneigt zur Längsrichtung (9) der Lagergasse (5) einfahren, welche Werkzeuge (7) in fliegender Lagerung in einem weiteren Schritt simultan mehrere Lagerbohrungen (6) durch die Relativbewegung zwischen ihnen und dem Werkstück (4) in Längsrichtung (9) der Lagergasse (5) feinbearbeiten.
Abstract:
The invention relates to a cutting insert kit in the form of a body (1) that is integrally manufactured from a brittle and wear-resistant material and comprises a plurality of cutting insert blanks (3), which individually include a chip removing cutting edge (8, 9) and are separable one by one from the kit via indications of fracture (4). According to the invention, the body (1) includes a base part (2) common to all cutting insert blanks (3) and to which the different cutting insert blanks are individually united via an indication of fracture in the form of a weakened connection member (4), which extends between the base part and a rear end of each cutting insert blank.
Abstract:
The invention is directed to a cutting tool assembly that include multiple diamonds to define multiple cutting tips. A first diamond is positioned in the cutting tool assembly to create a first groove in a microreplication tool and a second diamond is positioned in the cutting tool assembly to create a second groove the microreplication tool, wherein the first and second grooves define integer pitch spacing of a microreplication structure to be created using the microreplication tool. In addition, a third diamond is positioned in the cutting tool assembly between the first and second diamonds to create a land feature in the microreplication tool between the first and second grooves. The invention can improve land feature creation by using a third diamond tip, rather than leaving the land features untooled and defined by the original untooled surface of micro-replication tool.
Abstract:
The invention relates to a cutting insert (1) which is constituted of a plurality of coherent individual cutting inserts (2) which are disposed one after the other. Said insert can be used one after the other using an intermediary weakened point and detaching the preceding individual cutting insert (2) which was previously used for cutting. According to the invention, the cutting insert (1) is configured as a blade and has a lower (13) and an upper contact surface (14) to be received in an elongate recess (5) having a lower (15) and an upper mating surface (16) in the tool base (4) of a burring tool or disk milling cutter. Every individual cutting insert (2) is provided with a positioning means (3) which interacts with a complementary positioning means (9) of the tool base (4).
