The dry high-speed polishing machine adopts a high-speed operation design, horizontal rotation and planetary tumbling grinding, so that the abrasive medium and the product can be polished and polished in all directions without dead angles. The surface consistency of the product is good after polishing. It is applicable to all kinds of special-shaped products, and the product does not collapse, has no bumps, and has no dead angles to achieve a mirror effect. The equipment is safe and convenient to operate, the output quantity is stable, the consumables loss is small, and the machine power consumption is low. One person can operate three machines, saving labor costs. The equipment has high production capacity. One machine can produce 300 to 500 products at a time, and the quantity can be flexibly adjusted according to quality requirements. The equipment is green and environmentally friendly, the machine operation noise is small, and there is no wastewater or exhaust gas emissions, which promotes the green environmental protection of the entire industrial chain and is conducive to the surface process. The equipment fluid polishing is physical polishing, easy to clean, reduces waterless emissions, saves cleaning costs, and reduces pollution to the environment. The dry high-speed polishing machine can handle the surface polishing of stainless steel, zinc, aluminum, copper, and titanium alloys.
