The broaching tool 110 is a shaped tool for broaching and has a plurality of rows of teeth on its surface, the rows of teeth increasing and varying in size and shape from the cutting end to the cutting end. As the broaching tool 110 makes the broaching motion, each tooth cuts a thickness of metal from the workpiece to a desired size and shape.

The broach 110 is often used to machine round holes, splined holes, keyways, flats, contoured surfaces, etc. in batch and mass production, which have a relatively high requirement for the quality of the machined surface and, therefore, the broaching of the broach 110. When the machined surface roughness basically meets the requirement, but a local scratch defect exists, the broach 110 is checked in time, whether the cutting edge of the cutter tooth has a damaged notch or not is observed, whether the attached chips on the cutter tooth, particularly a finishing tooth are not cleaned up or not is observed, and whether the shape of a chip containing groove after the broach 110 is sharpened for many times causes unsmooth step shape or not, so that the chips are not curled smoothly, and the like.

Therefore, the chips remained on the broach 110 are one of the important reasons for scratching the machined surface, and in the actual broaching, the chips can easily fall off only when the broach 110 is sharp enough, and after the broach 110 is sharpened, the chips can smoothly fall off only when the first few chips are machined, and most of the chips are difficult to automatically fall off.

The chips which do not fall off are remained in the chip grooves, so that the curling and the formation of the chips can be hindered in the next broaching, the chip resistance is increased, the processing efficiency is influenced, the surface quality of the processing is reduced, and the processing surface of the workpiece can be scratched more seriously; when chips are continuously accumulated to form built-up edges, the cutting edges burn edges, so that the broach 110 is damaged, the damage of the broach 110 caused by the built-up edges is irreparable damage, and the broach 110 is often manufactured at a high cost, so that the machining cost is increased.
