- An Automatic Disc Finishing System — Centrifugal Disk Finishing MachinesA centrifugal disc finishing machine with an automatic tilting disc for discharge is a specialized type of finishing equipment used to deburr, and polish a wide range of parts and components. The automatic tilting disc is mounted on the bottom of the machine and is designed to pivot or tilt when the finishing process is complete. This tilting motion allows the finished parts to be easily discharged from the machine, without the need for manual handling or additional equipment. The machines can be highly automated and may include features such as programmable control panels, sensors, and other advanced technologies to optimize the finishing process and improve efficiency.“I don’t know how to choose the Centrifugal Disk Finishing Machine and Mass Polishing Media.”Contact us here for more information and a free quote!

Manufacturing processes



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.



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.
