Abstract: PURPOSE: To provide a milling cutter which can be tightened/fixed on/to a cutter main body by inserting a shoe carrying each pair of cutting inserts into each recessed portion of the cutter main body providing narrow gaps on an outer periphery of the cutter main body as much as possible. CONSTITUTION: An insert 11 is fixed to each shoe 12 with a screw, the shoe 12 abuts a pin 15 built in this shoe 12 on one side surface of each recessed portion of a cutter main body 10 in a projecting state from the shoe 12 by the pin 15 and a tightening screw 16 and thereby the shoe 12 is pressed on the other side surface of the recessed portion. As a result, the insert 11 can be disposed on an outer peripheral surface of the cutter main body with high density.

Abstract: PURPOSE: To reduce the friction between chips and an insert and thus prolong the lift of its cutting edges by extending a number of depressions to form an angle of 5 to 45 degrees with a line perpendicular to the cutting edges. CONSTITUTION: On use of a cutting insert 10, the chips that are released from a workpiece slide along a chip upsetting face 17. During this, a group of depressions 21 upset the chips and form runners in the transition part made by the chip upsetting face 17 and a chip forming face 19. This type of deforming action raises the chip temperature to reduce the friction between the chips and the insert 10. The curved form of the chip forming face 19 also suppresses the contact of the chips and the insert 10 to lower the heat conduction from the chips to the insert 10. Further suppression of the contact of the chips and the insert 10 needs the angle α in the range of 5 to 45 degrees these depressions 21 form with a line perpendicular to cutting edges 18 of the insert 10.

Abstract: PURPOSE: To attain operations of roughing and finishing, finishing and polishing, or roughing, finishing and polishing simultaneously with turning conducted in the lengthwise direction by disposing an additional cutting edge behind a main cutting edge when viewed from the feed direction of an insert. CONSTITUTION: This insert involves at least one cutting corner having a main cutting edge 13 and a secondary cutting edge 14, and is provided with the linear portion of the main cutting edge 13 formed at a set angle (α), such as 90 degrees, a relief angle (δ) variable over a wide range, and a nose radius R ranging from 0.2 to 3.2 mm. The cutting depth h2 of the secondary cutting edge 14 is less than 0.5 mm, and its setting angle (β) is a specific angle, such as 3 degrees. The relief angle (ε) is set at less than 2 degrees, and a distance between both points 16 and 17 on a straight line 15 coming into contact with the cutting corner at a point 16 and passing through an endpoint 17 on the secondary cutting edge 14 placed at a distance from the main cutting edge 13 is set at 0.5 to 2 mm. The production of a chip 18 is attained with the main cutting edge 13 by means of lengthwise turning, a very thin chip 19 is produced with the secondary cutting edge 14, thus it is possible to improve surface finishing positively.

Abstract: PROBLEM TO BE SOLVED: To provide a coated cutting tool insert used in metal machining, and to provide a texture-cured α-AlOlayer.SOLUTION: The alumina layer is characterized in improved toughness and adheres to a substrate covering its all functional part. A coated film is constituted of one or more heat resistance layers including at least one layer to be texture-cured α-AlOformed of columnar particles having a length/width ratio of 2 to 12 and having a 2 to 20 μm thickness. The α-AlOhas a strong (0006) diffraction peak. Improved wear resistance and toughness are obtained when a texture coefficient (TC) in a (0006) reflection is larger than 1.33 ln h+2 (h denotes the thickness of the α-AlOlayer) and when the surface of the α-AlOlayer is subjected to wet blast until an Ra value lower than 1 μm. An alumina layer having a strong (0001) texture is applied to a bonding phase enrichment cemented carbide substrate. This combination contributes to an increase of wear resistance and toughness.
