One of the most customary processes to deburr and/or precision-grind the surfaces of loose bulk items and machine components is vibratory grinding.
Here the parts to be processed move in spiral fashion in a mixture of abrasives and patented watery abrasive solutions in round machines (s. fig.) or rotate in vats (depending on the size). A large number of different abrasives offer a wide range of applications. The processing times vary here from approx. 1-8 hrs. or more depending on the requirement and material.
