The method has the following defects: 1. the quality of the rounding finish of the workpiece is too dependent on the operator. Slight action negligence in actual production can cause grinding out of tolerance, and the consistency and the efficiency are poor in maintaining the edge rounding precision. 2. The efficiency is very low. For example, a 600 mm diameter turbine disk (slot radius R0.5mm, upper tolerance 0.2, lower tolerance 0.2 mm) would require approximately 5 working days to complete the rounding. For example, a turbine disk of an aviation gas turbine is extremely expensive, mostly between 20 to 200 million RMB, and once one out of tolerance exists according to the acceptance standard, the whole workpiece is scrapped.

The other automatic rounding and finishing equipment is mainly in a robot or five-axis structure, and is provided with various functional tool libraries and a tool library in principle. After chamfering the edges by using a main shaft holding rotary file with a radial floating function and the like with large R angle requirements, using a small-diameter plastic wheel containing abrasive materials, wherein the edge of the abrasive wheel is provided with unconnected feather wings, and the plastic wheel rotates at high speed to round and round along the edge track. The method has the following defects: 1. when the tooth spacing of the palm-tree tooth-shaped mortises or the blade palm-tree tooth-shaped tenons of the turbine disc is smaller than the thickness of the grinding wheel, the rounding and finishing work of the workpiece cannot be finished. 2. The efficiency is not high. 3. Rounded and smoothed abrasives are generally stable, and the hair fins of abrasive wheels with smaller diameters (e.g., 20 mm diameter) are subject to very high forces of breakage.
