Abstract
A grinding machine tool with random eccentric orbital motion speed detection, the grinding machine tool comprises a body and a grinding disc, the body comprises a driving shaft and a tool holder connecting the grinding disc and having an eccentric distance relative to the driving shaft, and the grinding disc performs grinding in a random eccentric orbital motion when the driving shaft rotates. The grinding disc comprises at least one detected member on a side of the grinding disc facing the body for detecting a speed of the random eccentric orbital motion, and the at least one detected member defines a detection area with a range greater than or equal to twice the eccentric distance. Thereby, an accurate speed of the grinding disc performing the random eccentric orbital motion is obtained, so that the grinding operation of precision grinding which is gradually performed by automation is more precisely controlled.
