However, when processed in this manner, the following drawbacks are present: 1: the positioning surface and the clamping surface are inconsistent in the machining process of the first machine tool, the positioning is based on the tooth shape of the tooth, but the planes on two sides of the tooth shape are clamped during machining, and the tooth shape surface cannot bear too large clamping force and cannot be used as a clamping stress surface during machining, so that positioning deviation always exists, and the relative position degree of the existing product cannot meet the drawing requirement; 2: the piston blank is manually placed on the clamp of the first machine tool, and whether the tooth shape is in place or not is greatly related to the operation of operators, so that machining errors are easily caused by the fact that the operation is not in place; 3: the outer diameter of the piston (the special-shaped through groove and the tooth-shaped groove) is machined twice, and the outer diameter inevitably has about 0.02mm of size deviation.
