Centrifugal Barrel Finishing Machine, Centrifugal Barrel Finisher Manufacturer

Centrifugal Barrel Machine

Centrifugal Barrel Finishing Machine is high-energy tumble finishing equipment, often called “tumblers”, harperizers or Centrifugal Barrel Finishers. The machine performs mass finishing and polishing work using a rotating barrel or a drum containing media, parts, and finishing compound. The barrel finishing machine is used in manufacturing processes that require centrifugal force to perform high power, high precision, and mass-energy finishing.

Unlike other rotary barrel finishing machines that can only handle forces of 1G, the centrifugal barrel finishing Machine can be used on pieces capable of absorbing 5G power. It employs a force almost equivalent to 30 times worth of gravity. This machine has an exceptionally high speed and power. The power allows it to perform all the mass finishing processes like deburring, polishing, de-rusting, degreasing, and cleaning.

Various industries and applications rely on centrifugal barrel finishing machines to perform batch work. The manufacturers that use this machine achieve more finishing work than they would if they relied on manual labor.

How a Centrifugal Barrel Finishing Machine Works?

Centrifugal Barrel Finishing Machine works on a Ferris Wheel principle. This is where wheels rotate on a central axis. In the case of the barrel finishing machine, four barrels are mounted on the center turret. The turret wheel then turns, making a complete rotation of every barrel.

Every barrel in the machine contains about 60% to 80% of media, compound, and workpieces. Whenever the central turret rotates, there’s a centrifugal force that the machine generates on the workpieces and media. The force, together with the movement, causes the media and the workpieces inside to rub against each other. You will then end up with precise and effective finishing work.

Applications of the Centrifugal Barrel Finishing Machine

The Centrifugal Barrel Finishing Machine is a versatile equipment used in various applications such as:

Defence and Aerospace

The defense and aerospace industries need top-notch precision and accuracy in their finishing work. The Centrifugal Barrel Finishing Machine does great work in ensuring the industry achieves that and more. It offers excellent precision in its work within the shortest time possible while ensuring zero damage. This level of accuracy is exactly what’s needed to finish turbine blades and jet engine parts, among others.

Medical Device

Making medical device parts is a challenging process. The devices come in complex shapes and tiny sizes that are hard to achieve. Most of them are made of stainless steel, titanium, and cobalt, which are not easy to process.

In addition, you can’t afford to damage these high-end materials. Using a centrifugal barrel machine gives durable and strong medical devices. The accuracy and precision that the machine provides when making medical devices is something you can’t achieve working by hand.

Automotive Industry

Making vehicle parts needs a lot of polishing, cleaning, and finishing of the metals used. For every part to function effectively, it should have a smooth and accurate finish. You can use the barrel machine for polishing the fasteners, gear, and engine heads.

Jewelry Industry

Achieving fine jewelry needs accuracy and precision. The centrifugal barrel finishing machine is used to polish and deburr metal parts to produce smooth and beautiful jewelry pieces.

Advantages of the Centrifugal Barrel Finishing Machine

Time efficiency

Centrifugal barrel finishing ensures you can achieve batch processing within the shortest time possible. The machine generates the centrifugal force and speed needed for fast-finishing work. Additionally, you get to work on different parts at a go which makes batch finishing easy.

Consistent quality

Using the barrel finishing machine gives you consistency, accuracy, and precision in your work. If you do the job manually, you’ll likely get up to an 80% acceptance rate. The centrifugal barrel can give you up to a 100% acceptance rate on the first trial. You are sure to achieve isotropic and consistent tumbling in all directions.

Reduced risk of injury

Manual finishing and deburring work exposes the workers to repetitive motion injuries, which can have lifelong effects on their health. Using the machine reduces exposure to such injuries.

Improved surface finish

This method of barrel finishing allows you to obtain a fine mirror-polished surface. The machine applies the same amount of force and moves all the parts at once. Consequently, you achieve a seamless and smooth surface finish. The advantage is that metal or plastic work will produce the same quality surface finish.

Cost-effectiveness

It does save money when you use the barrel finishing machine instead of doing manual labor. The machine can take 95% of the workload. It is a substitute for human labor and assists in increasing production. These characteristics make accuracy and precision more affordable, productive, and worthwhile.

Centrifugal Barrel Finishing Machine Operation

Here is a step-by-step guide to using the centrifugal barrel finishing machine:

Preparation:Proceed to clear the area by washing all the components to eliminate rubbish and foreign materials. Left-over debris might affect the finishing work.
Media selection:Use the appropriate tumbling media if you want to achieve efficient finishing. Consider the size and shape of your media because these factors highly affect the outcome.
Loading the barrel:Load the parts into the barrel of your machine and distribute them evenly.
Add the media: Add the tumbling media to cover all the parts correctly.
Start the machine:Once everything is set and ready to go, run the machine until the finishing process is complete.
Remove and inspect:Turn off the machine and remove the parts from the barrel. Inspect to ensure they are uniform and have no defects.
Repeat: If the outcome has defects or doesn’t match your desired specifications, return it to the machine and run it again.

Tips and best practices for optimal results

Keep the cycle time between 5-15 minutes. Longer cycles may lead to a significant amount of heat generation.
Overloading may cause damage due to part-on-part contact.
Balance the machine well to avoid being too hard on the bearing.

What Media Used in the Centrifugal Barrelishing Process?

This type of centrifugal barrel finishing machine is versatile and works with different materials and media. The common materials include:

Metals: Stainless Steel, Brass, Copper, Titanium or Steel.
Ceramic: Ceramic silicon nitride, zirconia, or aluminum oxide.
Plastic: ABS, Acrylics, polyclymers, polycarbonate, and polyethylene.
Composite: The Fiberglass-reinforced plastics (FRP) or Carbon fiber-reinforced polymers (CFRP).

Picking the correct media guarantees that your finishing and polishing are done correctly. The centrifugal barrel finishing machine needs the following media to give a consistent finish:

Ceramic media
Porcelain media
Plastic tumbling media
Steel media
Organic media
