Description

Technical Field

[0001] The utility model relates to the technical field of mechanical cutters, in particular to a boring cutter. Background Art

[0002] The inner hole surface is also one of the main surfaces on the parts. According to the different relative connection relationships between the hole and other parts, it can be divided into matching holes and non-matching holes; according to its different geometric characteristics, it can be divided into through holes, blind holes, stepped holes, tapered holes, etc.; according to its different geometric shapes, it can be divided into round holes, non-round holes, etc. Hole processing tools are mostly fixed-size tools, such as drill bits, reamers, etc. During the processing process, the changes in shape and size caused by tool wear will directly affect the accuracy of the processed holes. In the prior art, when the drill bit is processing the hole, the debris is usually brought up with the rotation of the drill bit, and the generated debris will splash everywhere, making it difficult for the staff to clean up, and the vertically falling debris will fall on the edge of the hole, affecting the processing of the drilling hole;

[0003] The existing Chinese patent CN215998820U discloses a hole processing tool, which can control the height of the debris flying during the drilling process by setting an annular arc piece, thereby reducing the phenomenon of debris flying around, reducing the difficulty of cleaning the debris for the staff, and improving the work efficiency. In addition, the curvature of the annular arc piece can change the movement angle of the vertically rising debris, so that the debris is scattered at a designated appropriate position, reducing the impact on the hole rotation;

[0004] However, when drilling a workpiece, it is often necessary to drill multiple holes continuously. The above-mentioned hole processing tool relies on the arc-shaped piece to guide the debris, but the fallen debris will still fall on the workpiece. When switching the drilling position, the debris dropped from the drilling position still needs to be cleaned up. Utility Model Content
