| Message: | Features of RollsWe can supply the rolls (together with the spacers,Website:http://www.tubemills-reliantt.com, clamps, and sample plate) for the tube mills or for roll forming machines for the customers if get the drawings of the rolls. With our abundant experience and mature technology, we can also make the drawing according to some parameter information of the machine.Machining Process of Rolls1. Raw material preparation – forge piece: inconel2. Semi-finishing; Numerical control cutting machining3. Numerical control finishing machining4. Product inspection – dimensions, form and position tolerance5. Product inspection – hardness6. Customer inspection7. Finished-parts storage – shipshape8.
