"Swordsman" meet
It is understood that the "NC swordsman" competition with a total of four, 3 days. Among them, the first "limit thin", asked the players according to the drawing parameter programming and finish making ultra-thin aluminum glass; second "manual polishing", requiring players in the shortest possible time will be a bronze mirror blank polished maximum brightness; third, "cutting cans, cans of paint requires players to polish and to ensure the smooth, and not be broken; Fourth" knife ", requiring players blindfolded, cutting special size of workpiece. The implementation of the knockout system, respectively, into 4, 4 into the 3, 3 into the 2, 2 into the 1, the final winner will win the China Great Master of the crown, and selected the Chinese team to participate in the world skills competition in the world. Through the national auditions produced 10 players from all over the country, institutions.
April 6th at 10 in the morning, the first race officially started. The main players of the game on the accuracy of CNC machine tools to control the ability to program and process level, as well as good psychological quality. At half past three, the game is over. After the expert jury on-site inspection, Xiangyang Technician College Pan Zhiqiang, China Academy of Engineering Physics, Guangdong, technician technician college, Huang Jialong, Chengde technician college, the smooth clearance of the success of the promotion of the, the.
On hero in April 7th ten o'clock in the morning, "NC unit second swordsman finals competition began.
A member of the expert group will be unified lathe tool position, exciting moment to -- Huang Jialong, Shi Fengwu, Meng Qingjin, Pan Zhiqiang and other 4 players blindfolded. They will be in the dark, only by hearing, touch, to determine the extent of cutting tool, rough grinding mirror finish. 4 players carefully shake the hands of the handle, carefully listen to the cutter contact and the mirror blank sound, shake speed adjustment. I saw Huang Jialong carefully shook the handle; stone Fengwu sideways to listen to the voice of Meng Qingjin is cutting; both her hands, right hand left hand rotation button, a rocking handle; while Pan Zhiqiang shook his head with a handle, while the amount of feed...... The atmosphere is very tense, the audience on the sidelines are holding their breath, for fear of affecting the player's operation.
"This is a major test of the player's sense of vision, hearing, touch, as well as the knowledge of metal cutting, especially the cutting principle, metal materials, cutting tools, such as the overall grasp of the overall knowledge. Blindfolded, sensitive hearing is very important in the operation, the player to listen to the tool and workpiece contact to determine the degree of cutting tool. Touch, that is, the player must have a good grip on the handle. Only smooth operation, the cutting line is uniform, as far as possible to ensure the brightness. All of this requires the player must have a solid theoretical knowledge and solid basic skills, but also on the performance of the machine has a comprehensive understanding and a strong ability to adapt." Xiangyang Institute of technology, "China great expert" training team coach Liao Jian explained.
Two hours later, Huang Jialong took the lead in finishing the race. The expert group with roughness measuring instrument of the 4 players were polished to a mirror data measurement, Meng Qingjin, Shi Fengwu, Huang lung eventually progress into the third "on Hero: cutting cans" part of the competition.
A higher requirement on the ability to judge ability, players control CNC lathe accuracy and operation experience. Players have to spray the surface of the red, yellow, blue paint 3 cans for cutting, the cans outside the surface of the paint off, and can not be broken tank. As the top of the wall itself is only the thickness of 0.1mm, and the outer edge is irregular, brush a layer of film, still very thin. Using a very sharp tool, very easy to break the operation very difficult. Players can only through careful observation, listening to the cutter head cutting material surface sound intensity control tool, using the relationship between the workpiece and tool installation position to fast car out of film, and to ensure the integrity of the tank. This design is a great challenge for the players.
Shi Fengwu, Meng Qingjin finally got a victory, the success of the last fourth.
Ultimate challenge
The morning of April 8th 11, Shi Fengwu, Meng Qingjin's top master -- the two "the big three" the stage again, fourth off -- "a knife" ups. Their task is to pass a length of 200mm, diameter of 30mm cylindrical workpiece into a thin rod as thin as possible. As the saying goes, "Turner fears the car pole", but this problem is not inverted "NC swordsman". At 12 in the afternoon, the two finished their work one after another. The expert group on-site measurement, Shi Fengwu, Meng Qingjin's results were the diameter of 4.61mm and 4.75mm, only a difference of 0.14mm.
Shi Fengwu with superb skills, experience rich and good psychological quality, won the "NC 2 unit title, won the" big Chinese experts "title. The picture shows the NC unit 2 champion Shi Fengwu. Ren Dandan photo player Pan Zhiqiang in the game.
