1. The core insert pin introduces 2D and 3D type surface rough machining, non-installation, and non-working plane machining (including safety platform surface, buffer mounting surface, pressure plate plane, side datum surface). Before semi-finishing machining, the side datum surface is corrected to ensure accuracy.
2. Before finishing, correct the reference plane of the process reference hole; at the same time, check the allowance of the insert and check the machining accuracy. Finishing type surface 2D, 3D, side punch type surface and hole position, finishing process reference hole and height reference, finishing guide surface, and guide hole.
3. Processing should emphasize necessary and complex places, and the need for combined processing is clearly expressed. Process preparation concise, detailed expression, processing content as much as possible numerical expression. Inserts need to be processed separately, pay attention to the processing accuracy of the process requirements are indicated.
4. Precision Mold Accessories processing notes: after combined processing, the need for separate processing of the inset parts, combined processing when the process installation of separate processing of the benchmark requirements. Mold processing in the spring is easy to damage, so choose a long fatigue life of the mold spring.
