Aluminum-based silicon carbide (SiC content 60%) is a high-performance composite material that is widely used in aerospace, electronic packaging and other fields. However, its hard and brittle characteristics make threaded hole processing a difficult problem in the industry, especially the processing of M3 fine thread (depth 4-6mm, wall thickness only 0.5mm). Traditional methods face problems such as low efficiency, poor yield and high cost.
Processing Difficulties
Material Property Limitations: Aluminum-based silicon carbide has high hardness and brittleness, threaded hole processing is easy to break, and thin-walled structures with a wall thickness of 0.5mm are more susceptible to damage.
Traditional Processing Bottlenecks:
Manual tap processing takes >180 seconds/hole, and thread accuracy is difficult to guarantee;
The tap life is extremely low, and 3-5 taps are required to process each hole, which is costly.
MID Solution: Ultrasonic Precision Engraving and Milling
To address the above pain points, MID innovatively adopts ultrasonic machining technology, combined with integral PCD drills and thread milling cutters, to achieve efficient and high-precision machining:
Non-damage machining: Ultrasonic vibration cutting reduces material stress, and the wall thickness is 0.5mm without cracks or broken edges;
Tool life leap: A single tool can process 200 holes, which is 800 times higher than that of traditional taps (life is only 1/4 hole), greatly reducing costs.
Industry Value
MID's solution not only solves the accuracy and efficiency problems of aluminum-based silicon carbide threaded hole machining, but also provides reliable technical support for high-end manufacturing fields such as semiconductors and military industry, and promotes the iterative upgrade of hard and brittle material processing technology.
