With the pipe rotating, the grinder will grind the weld down smoothly to the inner wall of the pipe. The oil drilling industry uses long continuous pipe to reach the depths of oil cavities. Short pipes are welded together to achieve the proper length required. For good strength, the welds are large and protrude through the inside pipe wall.
ادامه مطلبA grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool. These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips 0.25 – 0.5 mm.
