Embodiment Construction
[0022] Fig. 4, Fig. 5 and Fig. 6 have shown the process of processing a kind of product part (fixed mold core shown in Fig. 2) according to the method of the present invention.
[0023] When processing the fixed die core in Figure 2, first process the fixed die core blank into the shape shown in Figure 4, and reserve a boss along the right edge of the surface 5 when milling the surface 5 (first surface) 8. The height of the boss 8 is 0.3 mm, and the width of the boss 8 in the direction extending from the right edge to the center of the surface 5 (the first surface) is 3.0 mm.
[0024] Then the semicircular concave surface 6 (second surface) of the fixed mold core shown in Fig. 4 is polished until its surface finish meets the requirements. As shown in FIG. 5 , at this time, a chamfer R is formed at the edge position of the upper right corner of the boss 8 due to polishing.
[0025] Then the boss 8 is milled away, and the chamfer R will not appear at the edge position where the...
