Abstract:
A system for managing slurry that is used for the machining of workpieces, wherein the slurry includes dispersion liquid and abrasive grains, the managing system comprising:a separator for performing a separation process on slurry that has been used during machining to recover at least recyclable abrasive grains from the slurry, wherein the separator rotates and applies centrifugal force to the slurry to separate components from the slurry;a first detector for detecting a specific gravity of the used slurry before undergoing the separation process in the separator;a second detector for detecting a property of a processed slurry that has undergone the separation process in the separator; anda controller, wherein the controller calculates a rate of recovery of at least the recyclable abrasive grains from the slurry by the separator based on the specific gravity of the used slurry detected by the first detector and the property of the processed slurry detected by the second detector, and wherein the controller controls the rotating speed fo the separator such that the calculated recovery rate reaches a predetermined, appropriate value.
