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.
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.
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.
Square vibratory polishing machine can be applied to the surface polishing, chamfering, deburring, polishing and brightening of small or big size parts. It does not affect the original dimensional accuracy of the product after grinding treatment. It lays a good foundation for some products subsequent electroplating, spraying and other surface treatment.
