When the steps are too many, the cutter can shake due to the increase of cutting resistance, so that the problems of diameter out-of-tolerance, finish out-of-tolerance and the like are caused;

4. some cutters have excessive steps and insufficient cutter rigidity, and the cutter can generate bending or fatigue fracture phenomena after the cutting time is too long.

5. The cutter is processed at a cutting speed during cutting, a workpiece needs to be withdrawn quickly when the cutter needs to be withdrawn after cutting is finished, the cutter is withdrawn from a processed surface during cutter withdrawal, the machining efficiency is influenced due to slow withdrawal, the processed surface is easily scratched due to quick withdrawal, and the problem is difficult to solve.

6. Some integral alloy forming cutters are made, and the whole cutter is scrapped due to cutter breakage or abrasion, so that the cutter cost is high, and the manufacturing cost of the machined part is overhigh. Many problems can not reach the requirements of efficiency, processing precision and smooth finish, and high-speed, high-efficiency and stable production is difficult to realize.

7. The use cost of multitool cooperation processing to the cutter is high, same one is by the processing hole, need the cutter to get into processing repetitive processing many times, not only caused the waste of cost in processing man-hour, also caused very big waste to the use cost of cutter, the use cost of enterprise is too high, it is low excessively to produce the profit, and multitool cooperation processing, precision and size and smooth finish all have the problem to be difficult to solve, even use shaping cutter, because preparation problem and design problem and use control problem, also have a lot of technical problem to control cost and quality to be difficult to solve, and shaping cutter is because the cutter uses excessively, the shape is very complicated, damage the coping to the later stage and all have the difficulty and the problem of certain degree.
