摘要： Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung einer Sägezahnstruktur (2), bei dem die Sägezahnstruktur (2) mit einem von einem Laser (3) emittierten Laserstrahl in ein Werkstück (6) geschnitten wird. Der Laserstrahl wirkt in einem Schnittpunkt (8) auf das Werkstück (6) ein. Das Werkstück (6) wird zumindest in einem Bereich um den Schnittpunkt (8) durch Bereitstellen eines Kühlmittels gekühlt. Nach dem Schneiden wird zumindest die Sägezahnstruktur (2) des Werkstücks (6) durch ein chemisches Verfahren bearbeitet, wodurch eine Oberflächenschicht zumindest der Sägezahnstruktur (2) des Werkstücks (6) abgetragen wird.
Die vorliegende Erfindung erlaubt es, die beim Laserstrahlschneiden entstehende Änderung des Gefüges eines Werkstücks auf eine Tiefe zu reduzieren, die mit einer chemischen Nachbehandlung entfernt werden kann. Der Herstellungsprozess von Sägezahnstrukturen kann somit erheblich verkürzt werden.

摘要： The invention relates to a machine tool holding device, comprising a carrier device (12, 14, 16, 300) by which means a tool being used can be actively connected to a drive shaft (54). The tool being used is actively connected to said carrier device (14, 16, 300) by at least one snap-in element (24, 26, 302), which is mounted in such a way that it can move against a spring element (20, 22). Said snap-in element engages when the tool being used is in the operating position and fixes said tool being used with a form fit. According to the invention, the tool being used is a circular saw blade (18, 32).

摘要： This invention concerns a saw blade (S) including at least one part with fine teeth (6) and at least one part with grouped teeth (7). The part of the blade with grouped teeth (7) includes a number of groups (4) of, for example, V-shaped indentations (10) in the blade (S), each pair of indentations defining a saw tooth (1). Each group (4) comprises an even number of indentations. In an arbitrary group (e.g. indentations one, three, five, etc.) a first imaginary line (A), drawn between alternate tips (11) or bases, is a straight line which forms a small angle (a) in relation to the longitudinal direction of the saw blade, the tips or bases being evenly distributed along the line. The invention also concerns a method and a device for producing a saw blade with grouped teeth by means of a tool comprising a punch and a punch die. The punch for cutting out the saw teeth is completely symmetrical and has substantially V-shaped tips. A saw blade blank is fed through the tool and cut in at least two stages. In order to form a group in a group-toothed part, in a first step, either the blank is tilted from a starting position at an angle (a) to the tool, or vice versa.

摘要： The invention proposes a tipped circular saw blade (10) comprising a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12), and a plurality of tips (13) made of a second material, each tip (13) fixed to a respective slot (12) to form a saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), each saw tooth (14) having a cutting edge (141). In accordance with the invention, each saw tooth (14) has a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material. The invention further proposes a method of manufacturing a tipped circular saw blade (10), the method comprising a step of forming a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12); a step of joining a plurality of prefabricated tips (13a), made of a second material, to the respective slots (12) of the peripheral region of the saw body (11), obtaining a preliminary tipped circular saw blade (10a); and a step of grinding the preliminary tipped circular saw blade (10a) to form a plurality of saw teeth (14), each saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), and having a cutting edge (141) and a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material.
