PURPOSE:To reduce adhesion of washings to a workpiece by injecting washing liquid to a polishing belt and effectively removing ground debris adhering to the polishing belt with use of said injection pressure, while absorbing the washings for recovery by means of a washings absorbing device. CONSTITUTION:Washing liquid is injected to a polishing belt 6 to which ground debris is stuck as grinding is effected from washing liquid injecting device 12 in the direction opposite to the travelling direction of the polishing belt 6. Moreover, with the injection pressure raised, the injected washing liquid removes the ground debris adhering between abrasive grains of the polishing belt 6. In succession, the washings are absorbed for recovery mainly by a washings absorbing device 13 whereby the washings are prevented from adhering on a workpiece W to be polished by the polishing belt 6. |
