Abstract:
A cutting tool for cutting a material is provided with a cylindrical body (500) having a cross-sectional diameter and a longitudinal rotating axis, (506) and a plurality of teeth disposed on a circumference of the body, each tooth having a cutting edge (514) and separated by a flute (512). The number of teeth is selected such that a ratio of the number of teeth to the diameter in millimeter (mm) is at least 0.75:1, that the cylindrical body (502) is rotated with a tooth pass frequency of at least 400 teeth-per-second, and that the tool (500, 501) is used for machining in a way that all the material is removed at a rate of rough machining and in a manner to eliminate finishing pass.
Abstract:
The present invention provides a beveling cutter including: a body with a shaft hole formed through the center; a plurality of 10 cutter blades (20) arranged at predetermined distances on the circumferential surface of the body, each having a radial primary blade (14) with a radial primary relief angle (a) ranging from 5 to 15 degrees and a radial secondary blade (16) with a radial secondary relief angle (b) ranging from 16 to 30 degrees; discharge grooves formed longitudinally between the cutter blades (20) to discharge chips produced in beveling; and a key groove formed at a portion inside the body, in which the helix angle (d) of the cutter blades (20) ranges from 5 to 45 degrees. With the beveling cutter of the present invention, it is possible to smoothly discharge chips produced in beveling and to prevent damage to the cutter blades (20).
Abstract:
A cutting tool having a plurality of cutting insets mounted about the periphery of a cutter body. The insert has radially extending projections each including a front cutting edge and rear cutting edge. Front and rear cutting edges from different adjacent projections together define an individual cutting side of the insert. The cutter body has a pocket for each insert. The insert engages the pocket side wall at multiple locations using only the front teeth from two or more projections. This permits a single cutter body and pocket design to be used with different insets and allows the inserts’ radial rake angle to be varied from one insert to the next by varying the front tooth height.
Abstract:
A method for cutting metal includes providing a rotating cutting tool and making a first cut in the material using a first tooth of the cutting tool, such that an amount of heat is conducted into the material. A second cut is made in the material using a second tooth of the cutting tool, before the heat dissipates from the material. The time between the first cut and the second cut is such that the heat softens the material and allows the second tooth to more easily cut the material. A cutting tool has a cylindrical body with a longitudinal axis. The cutting tool has multiple teeth spaced equally or unequally along the circumference of the cutter. The cutting edges are formed along the flutes throughout the length of the cutter by these teeth.
Abstract:
[Problem] To improve removal of chips generated when performing high feed processing of thin-walled materials such as impellers using a multi-edge endmill. [Solution] In a multi-edge endmill (1) having a cutting edge part (3) provided with multiple cutting edges and flutes (8) formed between cutting edges that are adjacent in the direction of rotation around the tool axis (O), the rake face of the cutting edge is configured from: the rake face (6a) of an end cutting edge (6) from the tool axis (O) to the outer circumference of the shank (2); the adjacent rake face (5a) of a corner R edge (5) that forms a surface different from the rake face (6a) of the end cutting edge (6); and the adjacent rake face (4a) of a peripheral cutting edge (4) that forms a surface different from the rake face (5a) of the corner R edge (5). Between the rake face (6a) of an end cutting edge (6) and the flank (6b) of the end cutting edge (6) that is adjacent on the forward side thereof in the direction of rotation (R), a gash (7), which configures a space that is continuous with the flute (8), is formed, and one surface that configures the gash (7) also serves as the rake face (6a) of the end cutting edge (6).
Abstract:
Die Erfindung betrifft ein Fräswerkzeug (1) mit einer Länge l gesamt und einem Durchmesser d gesamt und mit Schneiden (2) für die Fräsbearbeitung von zumeist metallischen Werkstücken. Um ein unkontrolliertes Versagen des Fräswerkzeugs zu vermeiden wird erfindungsgemäß vorgeschlagen, dass die Schneiden (2) teilweise oder vollständig aus polykristallinen kubischen Bornitrid (PcBN) oder polykristallinen Diamant (PKD) bestehen und der Durchmesser d gesamt des Fräswerkzeugs zwischen 7 mm und 40 mm beträgt.
