And the subject innovation is driving unit equipped with a drive motor, and a tool box section is connected to the drive unit to transmit power portion polishing, polishing by using the rotation of the polishing pad by a power transmitted from the tool box unit for performing a polishing operation in the polishing machine, the tool box part, is formed to surround the main rotating shaft connected to the drive motor, the upper tools are installed to be rotated in accordance with the free rotation of the lower tool comprising a; And forcibly rotating the polishing pad by receiving power of the main axis of rotation and, wherein the polishing pad and which is free to rotate the lower tool by the centrifugal force generated by the friction of the bottom surface and the upper tool and the lower tool is a housing cover contained therein including, but, the lower tool is provided with four primary pulley inside, four secondary pulley are installed one by one between the primary pulley, a drive belt wound around said main rotational shaft and the primary pulley and the secondary pulley such that in connection with each other jidoe, so as to have a different direction of rotation between the primary pulley adjacent to each other to provide a polishing machine having a drive belt tool box characterized in that the drive belt is installed.
According to the present invention, since the drive belt in the same manner the center distance of the belt and, in the interior of the tool box is adjacent to the main pulley to each other to rotate in the other direction, the shock is dispersed during polishing operation, and can offset the thrust force, the polishing was ever, vibration or shaking of the machines, which results is prevented from sagging or slip of the belt, as well as to increase the operation efficiency and durability, when grinding work to install additional control belt tool box is free to rotate or its rotation is control can be thereby efficiently control the polishing operation as well, there is an effect of improving the durability to polishing dust emissions by shielding and the rotary blades of the oil seal, published in the bearing.
