1. Rough machining
Use machining methods with larger cutting amounts to remove most of the excess material. For example, rough turning on a lathe or rough milling on a machining center. Rough machining can improve machining efficiency, but it will leave significant machining marks on the surface of the parts. After rough machining, the shape and size of the parts are close to the final requirements, but precision machining is still required to ensure accuracy.
2. Precision machining
Use smaller cutting quantities and high-precision machining equipment for precision machining. If high-precision CNC milling machines, grinders, etc. are used for processing. During the precision machining process, it is necessary to strictly control cutting parameters such as cutting speed, feed rate, and cutting depth to ensure the dimensional accuracy and surface roughness of the parts. For some parts with complex shapes, special machining methods such as electrical discharge machining and wire cutting may be required to complete precision machining.
4、 Testing and Quality Control Stage
1. Dimensional inspection
Use measuring tools such as calipers, micrometers, coordinate measuring instruments, etc. to check the dimensions of parts. Ensure that the dimensions of the parts are within the tolerance range required by the design. For critical dimensions, multiple inspections and records may be necessary to promptly detect dimensional deviations during the machining process.
2. Surface quality inspection
Detect the surface roughness of Mold Parts using equipment such as surface roughness meters. For parts with high surface quality requirements, such as optical mold parts, surface roughness testing is particularly important. Check the surface of the parts for scratches, cracks, and other defects. If there are any defects, they need to be repaired or scrapped.
5、 Assembly and commissioning phase
1. Component assembly
Assemble the processed precision mold parts according to the design requirements. During the assembly process, attention should be paid to the installation sequence and fitting accuracy of the parts. Use appropriate assembly tools and methods, such as press fitting, hot fitting, etc., to assemble parts.
2. Debugging and optimization
Debug the assembled Hardware Mold. Check the working performance of the mold through trial molding and other methods. Based on the debugging results, optimize and adjust the mold, such as adjusting the gap of the mold, modifying the size of the parts, etc., until the mold reaches the optimal working state.
The process flow of precision mold spare parts processing requires close coordination and high-precision operation in each link. Only by strictly following the process flow and strengthening quality control can high-quality precision mold parts be produced.
