Step drills can form pipe holes, small blocked holes, and chamfer at the same time in a single processing process. The shape of the drill tip depends on the material being processed. In addition to the drill tip shape, it measures the diameter of each step, core run out, taper, step length, and step angle. Depending on the drill's usage, the vehicle requires a range of 5 μm to 20 μm, with very low level measurement inaccuracies. Considering the measurement time, the priority is relatively low. Combining rotation and optical-base sensor can be used to assess the cutting profile and multi-stage latitude as rotation scanning.
