Jewelry polishing machine adopts the principle of eddy current flow and polishes the products through high speed rotation. When the rotating disc begins to rotate, the tumbling polishing abrasives and the products in the grinding disc move upward along the wall of the cylinder by centrifugal force. Then relying on the weight of the products and abrasives, they fall from the height of the grinding disc back to the middle of the rotating disc. This repetition causes the products and abrasives to move continuously in a spiral shape, resulting in a highly efficient grinding.
Vibratory polishing machine operates on the principle of generating three-dimensional high-frequency vibrations within a ring chamber, where the grinding media and parts are contained. These vibrations cause the parts and the tumbling polishing media to move in one direction, resulting in friction that facilitates surface finishing. After polishing, the original shape and dimensional accuracy of the parts are not damaged, the internal stress of the parts can be eliminated, thereby achieving a certain level of finishing, smoothness, and brightness on the surface of the part.
Centrifugal polishing machine from Norden is suitable for small and medium-sized products, especially for the heat treatment of shaped cavity holes. The polishing and deburring efficiency is increased by 10 to 20 times. It can effectively remove burrs, edges, rust and oil stains on the surface of your products, so that the surface can reach a certain finishing effect. Jewelry, hardware, ultra-thin parts, electronic components and other precision accessories can be polished with this machine.
Tumbling machine is also called rotating barrel polishing machine. It adopts the roller structure. The polishing abrasive and the products are placed inside of the roller. Through the rotation of the roller and the friction of the abrasive to achieve the polishing of the product surface. Tumbling machine from Norden machinery has high polishing efficiency and the polishing effect is uniform.
