  • A Rubber O Ring Plastic Finishing System -- Centrifugal Disc Polishing Machines

    A Centrifugal Disc Finishing Machine is a specialized machine that is used to polish and finish small metal parts, such as jewelry, coins, and other metal items. As the disc rotates, the parts are subjected to centrifugal force, which causes them to rub against the polishing medium and remove any imperfections or roughness from the surface. Rubber O-ring plastic centrifugal disc polishing machines are commonly used in industries such as automotive, aerospace, and electronics for finishing small rubber and plastic parts. They are a popular choice because they can produce a high-quality finish in a short amount of time.

    Manufacturing processes


    Mechanical Design

    CAD Drawing Planning

    CNC Machining

    The journey begins with the creative minds at Mass Polishing conceptualizing and refining the mechanical design of our mass-finishing machines. Through years of expertise and industry knowledge, our engineers meticulously craft designs that optimize functionality, durability, and efficiency.

    Once the mechanical design is finalized, Mass Polishing's team of skilled CAD designers transforms the concept into precise and detailed 3D computer-aided design (CAD) drawings. These drawings serve as the blueprint for every component, ensuring accurate manufacturing and assembly processes.

    With the CAD drawings in hand, the manufacturing process shifts gears to Mass Polishing's state-of-the-art CNC (Computer Numerical Control) machining center. This cutting-edge technology enables the precise fabrication of intricate parts and components with unparalleled accuracy, consistency, and repeatability.

    PU Casting

    Electric Control Box

    Mass Polishing harnesses the power of laser cutting to shape and refine various metal components. By utilizing high-powered lasers, we achieve clean and precise cuts, resulting in components that seamlessly integrate into the overall machine structure.

    To enhance the performance and durability of their machines, we employ polyurethane (PU) casting techniques. This process involves pouring liquid PU material into molds, which, when cured, form robust and wear-resistant parts. The PU casting method ensures optimal noise reduction, extended machine lifespan, and superior finishing results. An integral aspect of every mass finishing machine, the electric control box is meticulously assembled and wired by Mass Polishing's skilled technicians. The control box houses advanced electronic components, allowing for precise control and customization of the machine's parameters, such as speed, and time.
