The Advantages of High-Energy Finishing Machines

The term high-energy or high-speed finishing refers to industrial finishing methods where parts and media are subjected to pressure greater than the force of gravity through centrifugal force. 

The advantages of high-energy finishing over vibratory finishing are numerous. MFI Centrifugal Barrel Tumblers and Disc Finishers can reach upwards to 12 times the force of gravity (12G), making them much more aggressive and efficient than vibratory finishing. Rather than relying on vibration to wear away at the part surface, high-energy finishing uses the pressure and friction placed on parts and media to quickly remove material, polish surfaces, and create a uniform finish. This means that high-energy finishing can achieve a smoother surface finish in a fraction of the time, resulting in shorter processing times and consistent results.

In addition to being faster and more aggressive, high-energy finishing is also more precise than vibratory tumbling. It can achieve a higher level of surface finish, making it the preferred method for industries with precision parts. At MFI, we understand the importance of delivering a quality finish, which is why we offer a range of finishing equipment to meet your specific needs.

“The (Centrifugal Barrel Finishing) process produces results that can achieve hundreds of thousands of dollars in realized savings each year, and also eliminate the need for buffing and specialty wax bars to buff our products. There is always skepticism when a new process is introduced and claims to obtain results just as good as the “time honored” manual processes, but I’m very impressed with this process and I’d definitely recommend it.”

Perry Richards

Director of Engineering an Operational Excellence, Conn-Selmer, Inc.

“Our customers immediately noticed a difference when we started using the HZ-CBF. They asked, ‘Wow, are these 3D parts? This is incredible, these parts are amazing. What did you do?’ Mass Finishing gives us a leg up on the competition and we’re happy to partner with them. Anyone seriously looking at barrel finishers should take a close look at Mass Finishing. They’d be in good hands.”

Sterling Logan
