When a certain electronic component manufacturer was producing micro connectors, due to the extremely small thread specifications (M0.7*0.175), traditional taps were easy to break and had a short lifespan, and the internal thread accuracy was difficult to meet the requirements, resulting in low yield and high costs. The technical team of Sichuan Chuanhao Seiko Machinery Co., Ltd. customized a high-precision cobalt-containing high-speed steel tap based on the workpiece characteristics, processing parameters and other conditions. Combined with unique precision grinding technology, the tap life was increased by 3 times and the processing efficiency was increased by 40%. It not only solved the problem of easy tap breakage for customers, but also greatly reduced the frequency of tool replacement, saving more than 500,000 yuan in annual costs. The two parties reached a long-term strategic cooperation.
