Description

Technical Field

[0002] Drills with a diameter less than 3.175 mm are usually called micro drills, or micro drills for short. The first few turns of any drill are crucial because the drill is subjected to eccentric forces when it starts cutting. In addition, irregular shapes on the workpiece surface can cause lateral sliding, resulting in tool bending, breaking, or at least increased hole deviation.

Manual sorting can only sort one length at a time, and the sorting accuracy is not high. Although the sorting equipment available on the market has problems such as poor sorting accuracy, low efficiency, high misjudgment rate, and frequent failures. Summary of the invention
