4. After completion polished floor clean, begin to make fine hardening process, first the right amount of fine powder sprinkled on hard ground, then sprinkle sprays, natural fiber mats with a refurbished machine polishing to mix dry state, on if the fiber filled with a mixture of dry and hard, it must additionally for a piece (3-4 square meters each fine hardening process) Qingpu stone renovation, until after the completion of polishing pad put on clean stainless steel wire, spray a small amount of spray , once again full of polishing. After polishing mop net floor space of residual powder, the stone surface should immediately showing hard and bright surface. 10, the weight of the foot, disc pressure to bear: the machine weighs 250kg, the corresponding pressure on the disc up to 180kg or more. High hardness (such as granite, tiles, quartz sand epoxy terrazzo, epoxy floor, cement) and low hardness (marble, artificial marble) floor at the same time for the machine. 11, user-friendly design: Front electric lifting devices (removable disc more humane). Rear vertical force (more ergonomic mechanical requirements) machine leveling device, so that each point on the disc even force Baoshan refurbished stone grinding, grinding (block) level of loss. Removable movable armrests, easy easy to operate. 12, buffer damping device: output rotary compression spring mounted between the shaft and the Huangpu refurbished stone disc, disc grinding encounter large notches or rugged machine will be a great shock, then, spring will play buffer damping effect can keep the machine steady grinding, thereby reducing operating mechanic's labor intensity.
