This equipment is "Wheel Finishing & Polishing" is a product designed for the purpose. Within the four principles of abrasive grinding wheel is one trillion Media is a structure that rotates between the surface of each wheel is partially submerged in media, media formed due to collisions between the wheel Wheels - polished surface that is the way. Traditional way by hand, hand grinding wheel and the wheel surface, a worker as a final step of polishing the surface of the wheel to make a worker has worked scrubbing with abrasive materials. Approach this task as very godoel shall manah, time, labor, and expensive, but it was inefficient. The wheel-grinder of the mass-grinding efficiency, as well as improving the quality of processed product and the existing labor-saving in labor-intensive industries, mass production, and wheel-surface, were able to achieve a more perfect gloss. To provide an aesthetic appearance brilliant chrome-plated wheel surface before the coating and the coating must be. If the wheel surface is smooth, chrome-plated wheels, and then remained on the surface grooves and defects on the surface of a larger wheel and will damage the surface of the whole wheel is displayed. Therefore, to the extent necessary to wheel the surface coating on the surface of the wheel to smooth the rough parts of any home and for the purposes of effectively complete removal of this equipment is recommended.
