Document Type and Number:
WIPO Patent Application WO/2022/199602
Kind Code:
A1
Abstract:
A cutting blade (1), having an upper surface (11) and a lower surface (13) that are opposite in the vertical direction, an outer peripheral surface (16) located between the upper and lower surfaces, an upper cutting edge (12) located at the outer edge of the upper surface (11), a lower cutting edge (14) located at the outer edge of the lower surface (13), and a central axis (L5) running through the upper and lower surfaces. The upper cutting edge (12) comprises an upper corner edge (121), an upper main cutting edge (122), and an upper secondary cutting edge (123); the lower cutting edge (14) comprises a lower corner edge (141), a lower main cutting edge (142), and a lower secondary cutting edge (143); the outer peripheral surface (16) comprises a corner side surface (161), a first side surface (162), a second side surface (163), a third side surface (164), and a fourth side surface (165); the first side surface (162) is connected to the main cutting edge (122); the second side surface (163) is connected to the lower main cutting edge (142); the first side surface (162) and the second side surface (163) are parallel to the central axis (L5); the third side surface (164) is connected to the lower secondary cutting edge (143) and is inclined away from the central axis (L5) as extending away from the lower secondary cutting edge (143); and the fourth side surface (165) is connected to the upper secondary cutting edge (123) and is inclined away from the central axis (L5) as extending away from the upper secondary cutting edge (123). The cutting blade can improve the quality of surfaces machined by the double-sided cutting blade. Also provided is a cutting tool.
