The invention discloses a polishing machine for bearing processing. The polishing machine for bearing processing structurally comprises a machine base, fixed foot plates, an operation handle bar, a polishing scrap collecting device, a protection machine cover, a polishing table, a bearing fixing groove, a control panel, a roller shutter door, a movable machine case, a polishing electromotor, a transmission case, a transmission wheel, a transmission belt, a grinding wheel frame and a polishing grinding wheel. The fixed food plates are arranged on four ends under the machine base and are connected with the machine base through electric welding; the operation handle bar is inlaid to the right upper part of a front surface of the machine base and is movably connected with the machine base; andthe polishing scrap collecting device is arranged in the machine base. The polishing machine for bearing processing has the beneficial effects that the polishing scrap collecting device is arranged,so that a bearing can be polished, meanwhile, scraps produced by polishing are collected so as to be prevented from being accumulated in the machine body, and the equipment is ensured to normally operate; and meanwhile, the collected polishing scraps can be reutilized, so that the resources are saved, the polishing machine for bearing processing is effectively protected, the service life is prolonged, meanwhile, an environmental protection performance is improved, and the cleanliness of a working environment is kept.
