The principle of double roller pair units results in a low speed difference between roller and grinding table and thus in lower wear. The ability of the grinding rollers to move verti-cally enables them to automati-cally compensate for wear and maintain an optimum contact between the grinding element and the material being ground.Chapters 11 & 17 Flashcards | Quizlet20. Place one piece of metal flat on the table and hold or brace the other piece of metal horizontally on it. Then, tack weld both ends together. After that, set up the plates and add two or three more tack welds on the joint as required. Finally, starting at one end, make a uniform weld, add filler metal as required.
