Description

Technical Field

[0001] The utility model relates to the technical field of slotting cutters, in particular to a forming slotting cutter with a convenient replacement of the cutter head. Background Art

[0002] Slotting cutters are used to process molds for injection molding resin cases for mobile phones. Currently, these molds are cut while they are still "soft" using a super-hard alloy slotting milling cutter, and then hardened to improve wear resistance.

[0003] A search revealed the existing patent number CN201921024119.7, with the following patent title: A forming slot cutter comprising a cylindrical blade body, the blade body comprising two spaced and symmetrically arranged cutter heads, the cutter heads comprising a primary cutting edge, a secondary cutting edge, and a cutting tip, the intersection of the primary and secondary cutting edges forming the cutting tip, the primary cutting edge being perpendicular to the central axis of the blade body, the secondary cutting edge forming an acute angle with the central axis of the blade body, and the distance from the cutting tip to the central axis of the blade body being greater than half the axial diameter of the blade body. The forming slot cutter provided by the utility model has the advantages of saving processing time and ensuring a consistent width of the inner circular groove.
