摘要： 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.

摘要： [Problem]
To improve the discharge of chips generated when performing high-feed processing on a thin-walled material such as an impeller using a multi-flute endmill.
[Resolution Means]
A multi-flute endmill 1 comprising a cutting edge part 3 having multiple cutting edges and flutes 8 formed between adjacent cutting edges in a rotation direction around the tool axis O, wherein a rake face of each cutting edge is formed from a rake face 6a of an end cutting edge 6 from the tool axis O side to the outer peripheral side of a shank 2, an 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 an 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. A gash 7 that forms a space that is continuous with the flute 8 is formed between the rake face 6a of the end cutting edge 6 and a flank 6b of an end cutting edge 6 that is adjacent on a forward side thereof in the rotation direction R, and the rake face 6a of the end cutting edge 6 also serves as one surface that constitutes the gash 7.

摘要： The invention relates to a milling cutting tool (1) having a length l
total and a diameter d
total and two cutting edges (2) for the milling cutting of mostly metal workpieces. In order to avoid an uncontrolled failure of the milling cutting tool, the cutting edges (2) consist partially or completely of polycrystalline cubic boron nitride (PcBN) or polycrystalline diamond (PCD) and the diameter d
total of the milling cutting tool is between 7 mm and 40 mm.

摘要： 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).
