Abstract

PURPOSE:To make phase adjustment automatically and with good accuracy by providing arithmetic means for obtaining injection timing for injecting a balance weight fluid into a fluid pocket at a distance of 180 deg. from unbalance mass according to a change rate of each vibration displacement. CONSTITUTION:A plurality of fluid pockets 3 are arranged ring-shaped round a rotary shaft 2 of a grindstone 1, and a balance weight fluid is injected plural limes into the fluid pocket 3 near at a distance of 180 deg. from unbalance mass of the grindstone through an injection nozzle 50 to correct unbalance of the grindstone 1. At this time, in order to inject balance weight fluid into the fluid pocket 3 near at a distance of 180 deg. from the unbalance mass, the balance weight fluid is injected plural times while the injection timing is changed so as to find out the injection timing which can minimize the required time.
