    Steel roller roll process steps
    1. Cutting: use seamless steel tube for roller body, 45 round steel for shaft, Q235 steel plate for end plate, cut material with
    8mm machining allowance according to drawing size.
    2. Turning processing: Turning the joint surface of the mating parts of the roller body, end plate and shaft, etc., according to the H9/f9 matching accuracy.
    3. Weld the reinforcement ribs and shafts at both ends of the combined roller body, pay attention to correct the coaxiality of the shafts at both ends and the inner sleeve, and only weld the inner end plate on the shaft.
    4. Put the complete inner sleeve of the combined welding into the roller body, and the mating junction of the inner end plate of the combined welding and the roller body.
    5. Install the outer end plate on the shaft at both ends, and weld the junction of the outer end plate and the joint surface of
    the shaft and the roller body.
    6. Anneal the welded roll blanks to eliminate internal stress.
    7. One end of the steel roller is flattened and a standard center hole is drilled.
    8. Turning processing: Divide rough and fine turning steel roller body parts to the size required by the drawings. The working surface roughness of the roll body should not be greater than 1.6μm; the working surface of the roll has a radial runout tolerance of 0.025mm on the shaft support surfaces (rolling bearing installation parts) at both ends; the roundness of the working surface of the roll body is 0.036mm; bearing coordination The circle is processed with k6 precision. Then set the center frame, the end face of the car, and drill to size.
    9. Process the pattern according to the pattern requirements of the pattern steel roller. Then a hard chrome layer is plated with a thickness of 0.03~0. 05mm.
    10 Correct the static balance of the steel roller.

    Step 1 :Hot charging technicals
    Adopt hot charging technicals to install the shaft head, and then weld after contraction to ensure the quality of shaft installation.While other supplier are welding the shaft head directly.
    Step 2 :Dynamic balancing
    We will do 3 times of dynamic balancing test in the process of production of each rubber roller,which will ensure the using effect.

    In general,if it can be displayed within 10g on the dynamic balancing device, it is called dynamic balancing. But we can do less than 2g
    Step 3:Testing by making small sample before mass production
    We will make a small sample before the official production, after vulcanization, 24 hours later we will check the hardness, color,and Impurity situation. We will control the hardness tolerance within 3degree.

    If it is not qualified we will change the formulated immediately and to make the sample again till all the data reach the customer’s request
    Step 4:Quality control department
    Using all-imported laser tester to ensure that the geometric size and the accuracy of the roller can reach 0.01 mm
