The “group drill†with independent intellectual property rights and awarded the gold medal by the United Nations World Intellectual Property Organization in 1986 can improve the processing efficiency by 3 to 5 times under the premise of almost zero cost of the bit sharpening process. However, there are very few people who are skilled in this technology among domestic machining technicians and vocational technical school graduates.
To this end, the Suzhou Labor and Social Security Department and other leaders took the initiative to promote the “group drilling and sharpening skills†in the city since 2007. From February of this year, Suzhou City will first train teachers of mechanics schools such as lathes, fitters, CNC machine tools, and machining centers. From September onwards, the course will be included in the compulsory courses for machining majors in technical schools.
