The preface uses a variety of object-oriented methods to design a high-precision manufacturing and automation system from Northeastern University. It is known as the Stewat*Gough mechanism 112 parallel machine representative product tire pressure tester, three-bar six-degree-of-freedom flight training simulator 131. In the manufacturing industry, this type of machine based on the Stewat? Gough mechanism is called a virtual axis machine. Because it has the advantages of high rigidity, stable structure, high processing precision, and easy inversion of kinematics, it is 6! Shi Jiashun, Li Bo, Sun Wei and so on.

Shoe Cleaner

The shoes we wear every day need maintenance, which can extend the service life of the shoes and keep our shoes clean, comfortable and sanitary. Leather Shoe Care refers to a series of care work such as cleaning, sterilization, maintenance, polishing, coloring and mildew prevention of leather shoes, so as to restore the beautiful and bright new appearance of leather products and extend the service life of leather. The pH value of the detergent should be between 5 and 7.5. Otherwise, if the pH value of the detergent is greater than 7.5 or less than 5, the internal structure of the leather will be damaged and the service life of the leather will be shortened.
