Description

PCBN blade grooving cutter Technical Field The utility model relates to the technical field of PCBN blades, in particular to a PCBN blade grooving cutter. Background The grooving cutter is a cutter specially used for machining grooves or notches on workpieces, can perform precise grooving operation, and can provide excellent machining effect under the condition of higher hardness requirement, and compared with the traditional cutter material, the PCBN blade has higher wear resistance, and can remarkably improve machining precision and cutter service life. The Chinese patent with the application number of 202323384732.9 discloses a diamond cutter convenient for rapid clamping, which comprises a cutter seat, a cutter body and a connecting part, wherein the cutter seat comprises a supporting block, a clamping groove, a movable hole and a sliding groove, the front end of the supporting block is provided with the clamping groove, the bottom of the clamping groove is provided with the movable hole, both sides below the movable hole are provided with the sliding groove, the cutter body is arranged in the clamping groove, the cutter body is provided with a cutter hole corresponding to the movable hole, the connecting part is arranged on the sliding groove, the cutter body is downwards pressed and installed on the clamping groove of the cutter seat, a inserted bar and a stop block of the connecting part are clamped on the cutter hole under the supporting effect of a spring after the cutter body is installed, the cutter hole is limited, the sliding block is extruded inwards, the spring is contracted, the inserted bar is mutually close at the moment, the inserted bar is separated from the cutter hole, the limit of the cutter hole is eliminated, the cutter body is convenient to take out, the cutter body is simple in structure, and the cutter body is convenient and rapid to operate and quick to detach and use. The technical scheme has the following defects that the insert rod is driven by the spring to move to quickly disassemble and assemble the cutter in the actual use process, but the cutter and a workpiece relatively move to generate vibration due to the cutting force applied to the cutter in the machining process, the vibration easily causes the spring to shrink, so that the insert rod moves to influence the stability of the cutter after being installed, and the cutting precision is reduced.
