Abstract:
Die Erfindung betrifft einen scheibenförmiges Werkzeug (100), insbesondere ein Werkzeug, zur spanenden Bearbeitung von Kurbelwellen oder Nockenwellen mit einem eine Rotationsachse definierenden und um diese drehbaren, Scheiben- bzw. ringförmigen Grundkörper (1) und einer Mehrzahl von segmentartigen Schneidenträgern (2), die an der Peripherie des Grundkörpers (1) befestigbar sind, und mit mindestens einer Spannvorrichtung (10) zur Befestigung der Schneidenträger (2) an dem Grundkörper. Um einen scheibenförmigen Werkzeug zu schaffen, der an seiner Peripherie mit einer Mehrzahl von Segmenten bestückt ist, die in vergleichsweise einfacher und schneller Weise montierbar und befestigbar sind, wobei die Montage vorzugsweise auch maschinell durchführbar sein soll, ohne dass man zusätzliches Werkzeug und getrennt zu habende Spannelemente benötigt, wird erfindungsgemäß vorgeschlagen, dass die Spannvorrichtung (10) für die Befestigung und das Spannen eines Schneidenträger (2) jeweils einen am Grundkörper (1) beweglich gelagerten Spannkeil (3) aufweist, dessen eine Spannfläche (4) aufweisendes Abtriebsende (13) mit einer Aussparung (8) an einem Scheidenträger (2) und dessen Antriebsende (23) mit einem ebenfalls beweglich am Grundkörper (1) angeordneten Stößel (5) in Eingriff steht, wobei der Stößel (5) auf einem am Grundkörper maschinell verschiebbar montierten Schlitten (9) in Bewegungsrichtung des Schlittens federnd nachgiebig gelagert ist.
Abstract:
Die vorliegende Erfindung offenbart einen Scheibenfräser (1), der einen Scheibenkörper (11) mit einer zentralen Nabe (12) zur Aufnahme in einem Fräsantrieb und an seinem Außenumfang eine Mehrzahl Schneiden (21) aufweist. In dem Scheibenkörper (11) verläuft eine Mehrzahl innen liegender Kühlschmiermittelkanäle (3), die im Bereich jeder Schneide (21) zwei oder mehr Austrittsöffnungen (31) haben. Die Austrittsöffnungen (31) sind so ausgerichtet, dass ein Kühlschmiermittelstrahl (K), der aus dem Kühlschmiermittelkanal (3) austritt, auf die Schneide (21) richtbar ist. Darüber hinaus wird noch ein Herstellverfahren für den Scheibenfräser (1) beansprucht.
Abstract:
The invention relates to machine tool (10) machining units (7, 9) that are used as actuators for tensioning and releasing tools or tool parts. Said machining units (7, 10) can optionally also be used as sensors, i.e. as sensing devices for checking that the tools are sitting correctly. The invention allows tool-changing times to be reduced and process safety to be increased when releasing and tensioning the tools.
Abstract:
A rotary slitter (10) includes a disc-shaped rotary slitter body (12) having a rotation axis (AR), opposing first and second surfaces (20A, 20B), a circumferential surface (20C) connecting the first and second side surfaces (20a, 20B), and a cutting portion (14). The cutting portion (14) includes an insert seating construction (24B), a groove (26B) formed in the first surface (20A) and surrounding the insert seating construction (24B), in a view of the first surface (20A) along the rotation axis (AR), and a positioning hole (30B). The rotary slitter (10) further includes a positioning screw (32) mounted to the positioning hole (30B) and configured to adjust a position of a cutting edge of a cutting insert (22A, 22B) mounted to the insert seating construction (24B).
Abstract:
A cutting insert has parallel first upper and lower faces, parallel second upper and lower faces, first and second side faces, first and second cutting portions, and first and second mounting grooves. The second upper and lower faces are perpendicular to the first upper and lower faces, respectively. The first and second side faces are located at respective ends of the cutting insert. The first cutting portion has a major cutting edge at an edge between the first upper face and the first side face, while the second cutting portion has a major cutting edge at an edge between the second upper face and the second side face. The first mounting groove curvedly or linearly extends from the first cutting portion oppositely to the second cutting portion, while the second mounting groove curvedly or linearly extends from the second cutting portion oppositely to the first cutting portion.
Abstract:
A cutting tool and cutter body assembly (20,20'), including a disk-shaped cutter body (22) and a plurality of support pads (24,24') removably retained therein, the cutter body (22) having- an axis of rotation (R), two opposing end surfaces (26a,26b) and a body peripheral surface (28) extending therebetween. Each support pad (24,24') intersects one of two annular-shaped planes (P1) equidistantly offset from opposite sides of a median plane (M) perpendicular to the axis of rotation (R), and the cutter body (22) intersects neither of the two annular-shaped planes (P1). Each support pad (24,24') is configured to make operative contact with a machined surface of a workpiece perpendicular to the axis of rotation (R). Each support pad (24,24') has opposing upper and lower surfaces (44,46) and a pad peripheral surface (48) extending therebetween, the pad peripheral surface (48) having an upper portion (50) intersecting the upper surface (44), and the upper portion (50) exhibiting N-fold rotational symmetry about a pad axis (A2) non-perpendicular to the lower surface (46).
Abstract:
A cutting body (12) for a metal-working machine tool includes a cutting portion (16) extending from a body portion (14). The body portion (14) is configured to fine-tune the position of the cutting portion (16). The body portion (14) includes an inner sub-portion (39) and an outer sub-portion (40) disposed between the inner sub-portion (39) and the cutting portion (16). The outer sub-portion (40) includes adjacent first and second sections (40A,40B). The first section (40A) is configured to elastically bend, extends between the inner sub-portion (39) and the cutting portion (16), and comprises a face adjacent the second section (40B). The second section (40B) includes a biasing surface (35) and a biasing sub-portion (36A) configured to hold a biasing member (17). When the biasing sub-portion (36A) is moved due to biasing of the biasing member (17) against the biasing surface (35), the first section (40A) is configured to bend and thereby change position of the cutting portion (16) extending therefrom and allow fine-tuning thereof.
