Abstract:
The present invention is directed to a cutting tool, comprising: at least one cutting insert; a tool body including a pocket portion to which the cutting insert is mounted; a means for fixing the cutting insert to the pocket portion of the tool body; and a screw for finely adjusting the position of the cutting insert fixed to the pocket portion of the tool body. The screw has a head portion, a threaded portion and a portion for connecting the head portion to the threaded portion. The pocket portion has a bottom surface with a screw hole formed thereon into which the threaded portion is fastened. It also has a side wall comprising a surface for closely contacting the head portion of the screw. The head portion of the screw closely contacts and resiliently pressurizes the close contact surface of the pocket portion when the threaded portion is fastened into the screw hole.
Abstract:
The screw has two or three non-circular super-imposed recesses. The depth of each recess is less than 1.2 mm and there is a less than 1° of draw in each recess. The screw head recess is formed using a punch (10) in a cold-heading process. The punch is formed in a profilating CNC machine, cutting the profiles (12, 14, 16) of the punch to a tolerance of better than ± 0.025 mm. A method of manufacture of a cold-forming punch for such a screw comprises providing a profilating head as one of the tools one a turret mounted adjacent the chuck in the CNC machine. The profilating head has several cutting elements, each being adjustable with respect to one another: axially, radially and angularly.
Abstract:
The invention relates to a milling cutter with a basic body (2) and an annular support (20, 20a, 120), in which the basic body (2) has chip spaces (3) around its periphery (4) and suitable recesses (9) to take cassettes (7) with cutters (5), in which the annular support (20, 20a, 120) is fitted on a face (17) of the basic body (2) away from the cutters (5) and the annular support (20, 20a, 120) is designed to support the cassettes (7) axially. The essence of the invention lies in the channel-like recesses (9) for the cassettes (7) which are open towards the chip spaces (3) each of which has a base (12) and walls (10, 11) which are smooth as far as the front (17) of the basic body (2) and have no projections and/or undercuts at all.
Abstract:
The present invention relates to a milling cutter (10) having a cutter body (12) and a plurality of replaceable tool cartridges (16) circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits adjustment of the tool cartridges (16) in the direction parallel to the axis of rotation of the cutter body (12). The adjustment mechanism includes an adjustment screw (52) threaded into a corresponding bore (54) in the cutter body (12). The head (56) of the adjustment screw (52) projects into an inclined throughbore (60) in the tool cartridge (16). When the adjustment screw (52) is turned, the head (56) of the screw bears against the inner surface of the throughbore (60) causing the tool cartridge (16) to be axially displaced. A locking screw (62) is tightened to secure the tool cartridge (16) in place after it has been adjusted.
Abstract:
A cutting tool (10) has an adjustment mechanism for adjusting the location of a cutting insert (15) seated therein. The cutting tool (10) has a tool body (11) provided with an adjustment bore (50) and an abutment member bore (32) intersecting the adjustment bore (50), and also has an abutment member (30) and a worm screw (40). The abutment member (30) is located in the abutment member bore (32) and the worm screw (40) is located in the adjustment bore (50) and screw threaded into the worm screw bore (56). The abutment member (30) is located in a first location along the abutment member bore (32) when the worm screw (40) is in a first screw rotated position and the abutment member (30) is located in a second location along the abutment member bore (32) when the worm screw (40) is in a second screw rotated position.
Abstract:
Die Erfindung betrifft einen Schneidenträger (11) zur Befestigung an einem Fräsmesserkopf, bestehend aus einem schaftförmigen Stift (11) und einem Kopf, mit eingelöteter Schneide (12) mit einer von einer Spanfläche (27) und einer Freifläche (28) gebildeten Nebenschneidkante. Erfindungsgemäß weist die Nebenschneidkante eine Verrundung (25) auf, deren Radius von einem Nebenschneidkantenende (25a) zumindest bis zur Schneidkantenmitte oder bis zu dem anderen Nebenschneidkantenende (25b) kontinuierlich ansteigt.

Abstract:
Die Erfindung betrifft ein Verfahren zum Erzeugen von Hinterlegungen an den Zahnflanken (2', 2'') der Zähne (2) eines verzahnten Werkrades (3), wobei das Werkrad (3) von einer Werkstückspindel im Wesentlichen kontinuierlich drehangetrieben wird und ein von einer ersten Werkzeugspindel in einem festen Drehzahlverhältnis zur Werkstückspindel drehangetriebenes erstes Schneidkantenwerkzeug (6) zufolge einer der Drehbewegung überlagerten Vorschubbewegung jeweils erste Zahnflanken (2') der Zähne (2) bearbeitet und nach einer Drehrichtungsumkehr ein zweites Schneidkantenwerkzeug (6) zweite Zahnflanken (2'') der Zähne (2) bearbeitet. Um die gattungsgemäße Vorrichtung, das gattungsgemäße Verfahren sowie den gattungsgemäßen Messerkopf gebrauchsvorteilhaft weiterzubilden, wird vorgeschlagen, dass das zweite Schneidkantenwerkzeug (6) von einer zweiten Werkzeugspindel drehangetrieben wird, welche im Zuge der Drehrichtungsumkehr an die Stelle der ersten Werkzeugspindel in eine Arbeitsposition zum Werkrad gebracht wird.
Abstract:
A tool for use in machine-tools with a cutting head (14) has at least one interchangeable cartridge (24) which can be releasably fastened to the cutting head and which carries an interchangeable insert. The interchangeable cartridge can be adjusted on the cutting head in the advance direction of the insert by the action of an adjustment mechanism. The adjustment mechanism has a tapered ram (46) which can move along a guide (42) of the cutting head (14) arranged parallel to the plane of the insert and essentially perpendicular to the advance direction of the cutting head (14). The tapered ram has a tapered surface (44) which is inclined at an acute angle to the direction of sliding and which is contiguous with an inclined shoulder (54) of the interchangeable cartridge which makes a right angle, in the direction of the inclined tapered surface, with the advance direction. In order to transfer the torsional stresses produced by the cutting force on the blade of the tool to the cutting head (14) without stressing the means for securing the interchangeable cartridge (24), the inclined shoulder (54) and the facing tapered surface (44) also have an inclined undercut perpendicular to the inclined tapered surface and transverse to the advance direction, which enables the interchangeable cartridge (24) to interlock with the conical ram (46).
