. The cement concrete ground which worked through the ground polishing machine is fiat, smooth, high-coagulability, high-intensity. The result which worked by the traditional artificial polishing can not compare to of it; . Enhanced the working efficiency greatly, reduced the labor intension, It raised the work efficiency 10 times compared to the traditional burnish working procedure; . The extracting slurry disk can be installed on the spatula without any tools, it can be used for compaction, extracting slurry in the concrete making early time; (The extracting slurry disk for to buy in addition) . The high quality absorption eliminated the trembling of the spatula thoroughly caused by the guard ring shaking, guaranteed the project quality; . It has the safe compelling switch, if the machine is out of hand accidentally, the safe switch will shut off the engine rapidly, it will protect builders safety and prevent the machine from damage; . Main technical parameter: 1, Engine Robin EX-17 6HP 2, Speed reducer Twpx80 1:20 3. V belt B660 4. Spatula 350×150×2mm 5, Principal axis rotational speed 120-140/min 6, Size 1850x920x600 (length ×width× height) 7, Weight 74Kg
