A Centrifugal Disc Finishing Machine, also named Eddy Current Polishing Machine or Vortex Surface Finishing Machine, is an equipment designed to remove burrs and grind and polish surfaces of small to mid-sized metals, plastics, and other materials. It looks like a blender, only bigger. It contains a rotating disc instead of blades in a blender, and a bowl structure that holds finishing products, abrasive media, and the item/s being worked on. The machine’s primary function is to perfect workpieces by removing sharp edges and burrs and smoothening surfaces. Centrifugal disc finishing machines can also achieve specific surface roughness. It achieves results by rotating a disc at the base at high speed, allowing workpieces, abrasive media, and finishing compounds to rotate within the chamber.
Centrifugal disc finishing machines can be used in various industries including, aerospace, jewelry, automotive, and medical. The machine possesses various advantages, including edge quality, improved surfaces, faster processing, and repeatable results. Centrifugal disc finishing machine features an easy-to-clean design, overload protection, speed control, and vibrational and soundproofing functions.

What is the Function of a Centrifugal Disc Finishing Machine?
To understand the function of the centrifugal disc finishing machine, start by taking a look at the picture above. One item looks polished and perfect while the other needs some more work. This is where the Centrifugal disc finishing machine comes in.
From the picture, the first item needs polishing to achieve the shine on the second item. The centrifugal disc finishing machine achieved the result by rotating abrasive media at a high speed. The finishing process may involve one or many functions depending on the expected results. For instance, the process can involve descaling, radiusing, deburring, removing defects, cleaning, polishing, and brightening.
How Does Centrifugal Disc Finishing Machine Work?
Centrifugal disc finishing machine relies on an electric motor and centrifugal force to produce the desired results. The machine uses centrifugal force to fling the part/s and tumble the finishing components against the machine’s drum wall.
To use the machine, load the items you need the machine to work on. Add abrasive media and finishing components into the bowl too.
Each centrifugal disc finishing machine has its working capacity. These include a 20liters, 42liters, 85liters, 169liters, and 342liter. Suppose your machine has a working capacity of 42 liters. You can fill it with your parts, finishing components, dry compound, and or water/liquid up to its capacity.
The finishing process begins when you turn on the machine allowing the disc at the base to start rotating. This moves all items in the chamber upwards and outwards against the chamber’s wall. The walls on the upper part of the chamber slow the components and force them to move downwards and inwards towards the rotating disc to restart the finishing process over and over until the process is complete.
The process is aggressive thanks to the high speed of between 60 rpm to over 400 rpm. Most centrifugal disc finishing machines have variable speeds, allowing the operator to adjust the speed based on the parts being worked on. The machine operator also sets the rotating speed and processing time. Once the process is complete, you can tilt the chamber to remove the finished parts from the machine.
Where to Use Centrifugal Disc Finishing Machine?
Centrifugal disc finishing machine is a versatile equipment useful in many industries. Here are some of the areas you can use the machine.
Metalworks: The machine is used to deburr and polish metal parts made from brass, aluminum, steel, and copper. The machine removes excess material resulting in high-quality polished parts. Manufacturers making jewelry, medical equipment, automotive and aerospace parts can benefit from this equipment.
Ceramics and composites: manufacturers using ceramic and composites in producing products can use a centrifugal disc machine to remove excess material, achieving a smooth surface on parts.
Plastic parts: centrifugal disc machine can also be used to remove flashing, burrs, and excessive material of plastic parts.
Advantages of Centrifugal Disc Finishing Machine
There are several advantages to using a centrifugal disc machine. These include:
Versatility: the machine can be used to process various materials, including metal, plastic, ceramic, and composite parts.
Customization of parts: the machine operator can adjust the vibratory action to fit specific part specifications.
Cost-effective: the machine can process many parts in a short time, leading to efficiency and cost-effectiveness.
Suitable for delicate parts: the machine is gentle on fragile and delicate parts.
Step-by-step Guide on How to Use Centrifugal Disc Finishing Machine
New to using a centrifugal disc finishing machine? A qualified or trained operator should run the machine. Fortunately, learning and using the machine is easy. Here is a step-by-step guide on how to use the machine.
Prepare the machine and Parts
The first step is ensuring the machine is set up correctly. You might need a professional to complete this process. Also, ensure you have the part you need the machine to work on ready for processing.
Load the Machine with Parts
Add the part or parts for processing in the bowl alongside other components such as water/liquid, media, and finishing components to help in the finishing process.
Make Adjustments to the Control Panel
The control panel is visible. It might be a touchscreen panel where you can set up the rotation speed, processing time, and other parameters.
Switch on the machine
Turn on the machine to begin the finishing process.
Unload your finished parts
Turn off the machine and tilt your chamber to separate media from your parts.
Clean the machine
Once you are done using the machine, clean it and perform the maintenance routine as required.
Types of Media to Use in a Centrifugal Disc Machine
Choosing abrasive media is crucial to the quality of the processed parts. Therefore, it is important to choose the right media depending on the results you are looking for. Here are the media you can use in a centrifugal disc finishing machine.
Plastic media
Plastic media come in two forms, cones and cylinders. Cone plastic media are gentle, thus ideal for processing soft materials like plastic and aluminum. They are ideal for light polishing, deburring, and radiusing. Meanwhile, cylindrical plastic media is good for burnishing and polishing softer materials.
Ceramic media
These come in various forms, including cylindrical, spheres, and cones. Cone ceramic media is used to achieve satin finishes on parts. Sphere ceramic media is used to polish while cylindrical ceramic media is used on delicate and intricately shaped parts.
Natural media
This could be walnut shells, corn cobs, and other natural stones. The media is ideal for cleaning and polishing delicate parts.
