    Automatic roller processing


       

            Baoke Machinery takes the German advanced roller manufacturing technology and process, and the production process of"Direct Fitting, Locating datum", The roller equipments are characterized by"One point positioning, multi-point maching", from the tube processing, shaft processing to bearing processing all take this mehtod. The whole process is automatically finished on the same position. Which differs much from the other domestic manufactuer. As a result, the risk of inner stress and deformation caused by welding is reduced. And it avoids big deviation out of repeated fixation. The global error of coaxiality, cylindricity and concentricity always stay at greater than 0.10 MM, Finally to ensure that the products are precision requirement, and make the product rotation resistance, dustproof, waterproof properties are higher than the national standard. The service life of roller up to S0,000 hrs. On the average, the replacement  scrape rate for our operating rollers are lower than 10%, and rotation drag coefficient reaches 0.018。
