Zhao Cunyu character makes Shangong machinery tough equipment

Able to lift 6 tons of goods Shangong machinery 660D loader, which is equivalent to an adult male African elephant weight, so much of the power of the loader's legs and feet is also a test, and Zhao Cunyu's "SEM Machinery Engineer checks differential" is equivalent to the loader's ankle.

Zhao Cunyu is the last product SEM Machinery brand improvement engineer, working in a tiny bit is not a mistake. You know, in the construction machinery precision world, hair one percent width crack may be in bad environment and heavy load conditions lead to gear broken, differential damage, even the machine rollover, break down.

0.15mm is the grinding allowance of the inner hole of the differential gear, which determines the smoothness of the inner wall of the gear.

5 degrees Celsius is the gear tempering temperature allowed error, too high or too low will have an impact on the hardness of the gear.

The beginning of a project, he has done a lot of homework, after repeated tests for several weeks, he found the most matching analysis tool -- fishbone model of Six Sigma "".

The use of fishbone models requires multidisciplinary knowledge, such as material science, mechanical processing, heat treatment, chemistry, and so on.

Fishbone model is actually more like a cross over the root, if the fault is of grass root, the potential cause of the failure is that causes potential causes of lateral root, root is the root. For a veteran engineer, in the range of possibilities in unraveling also need a solid professional knowledge and keen insight.

Zhao Master said: "this fishbone finally analyzed, there are 14 potential reasons, and ultimately through the experiment, instrument testing, you can lock the grinding allowance and tempering temperature is the root cause."

Master Zhao mentioned six sigma is a leading international quality management tools, had to learn English Six Sigma courses, Zhao no less hard.

Looking at the learning materials of the Six Sigma Black Belt, master Zhao said, "you see, this is all the notes I wrote at that time, and a large pile of piles, most of which are in English."."

A English dictionary, a record packed notebook, plus countless times before repeatedly in the mind of a review, English foundation General Zhao just simply relying on a shaft strength to the Six Sigma bite down, a few companies in the black belt expert.

"He is a silier who has a never give up does not solve the problem of the spirit." Zhao Leadership Manager Li Yougang said of him.

A load on the body there are tens of thousands of parts, each part is like Zhao Cunyu engineers to test, check, we can know that only have a tough character to make tough devices such as SEM machinery.
