Dongguan’s fully automatic micro drill grinder reaches internationally advanced level: The project “Research and Application of Key Technologies for Fully Automatic Micro Drill Grinder” jointly completed by Dongguan Technician College and Guangdong Dingtai Robot Technology Co., Ltd. has passed the scientific and technological achievement appraisal of Guangdong Mechanical Engineering Society, reaching the international advanced level. This project has solved technical problems in the grinding process of PCB micro drills. The production efficiency has increased by 242% compared with semi-automatic equipment, the grinding yield rate has reached 98.75%, and a number of patents have been applied for, which have been applied in many enterprises.

Jiangxi Zhongzhi Precision Machinery achieves micron-level precision machining: Jiangxi Zhongzhi Precision Machinery Co., Ltd. uses a 1-micron five-axis machining center produced by JST. Through the independently developed intelligent compensation system, the machining error is controlled within 1/40 of the diameter of a hair strand, successfully entering the supply chain of leading enterprises such as Midea and Gree. The intelligent manufacturing array composed of 42 precision processing equipment of the enterprise has compressed the production cycle from 72 hours in traditional manufacturing to 50 hours, and the yield rate has increased to 99.98%.

Huairou Science City builds a high-end precision machining sharing service platform: The high-end precision machining sharing service platform located in the core area of Huairou Science City has provided services such as non-standard customized processing of scientific instruments for many innovative entities, filling the gap in regional precision machining services. The precision of the platform’s equipment reaches the micron level, which can meet the strict requirements of high-end scientific instruments for components. Customers can get finished products in as fast as one day, compared with the previous need to go to other provinces and cities, which took about a month.

Domestic enterprises make breakthroughs in micro-precision machining of medical parts: In the field of medical manufacturing, domestic enterprises such as Jingwei Shida and Mofang Precision have achieved key technological breakthroughs, and some products have surpassed the imported level. The shaft parts processing technology developed by the National University of Defense Technology has a roundness accuracy of 0.1 microns, leading the world. Some enterprises can reduce the surface roughness of artificial joints to Ra0.01μm by optimizing the servo motor control algorithm. They also use machine vision to automatically identify surface scratches and burrs with an accuracy of over 99%.

Jiangmen enterprises introduce precision electrochemical machining technology: Dianke Precision Technology (Jiangmen) Co., Ltd. was officially put into production and reached a strategic cooperation with Germany’s PEMTec to establish the Precision Electrochemical (Asia) Technology Application Center. The center has introduced PECM precision electrochemical machining technology and equipment, with processing efficiency 50% higher than traditional technologies and engraving precision up to 5 microns, which can engrave precision lines a hundred times thinner than hair strands on thumb-sized metal parts.
