Large numbers of parts can be uniformly edge and surface finished in centrifugal mass finishing equipment. Process development in recent years has facilitated the creation of very refined surface and edge effects by processing parts in a series of successively finer processes in high-energy centrifugal equipment

Nearly all manufactured and fabricated components require some edge and surface finish preparation prior to final assembly. Although many parts today are still individually handled and processed with hand tools or hand-held power tools, it has become almost universally accepted that utilization of mass finishing techniques is far to be preferred on both their economic and technical merits, whenever possible. Utilizing energy developed from motion imparted to the containers or vessels in mass finishing equipment, loose abrasive or polishing media can produce a wide range of desirable edge and surface effects.


The information below discusses a variety of important applications for Centrifugal iso-Finishing. Contact me at ddavidson@deburring-tech-group.com for help in making arrangements for sample part finishing your parts.


SLIDE PRESENTATION, Centrifugal Iso-Finishing Equipment, Processes, Media and Before and After Part Finishing Examples


 

Centrifugal Iso-Finishing Machine and Application Videos.

See the comparative chart below which illustrates the various models of Centrifugal Finishing machines.that are among the machines shown in the videos below. Equipment overall dimensions as well as that of the hexagonal work chambers are also given below. Parts can be processed in bulk or processed in individual compartments. See the illustration of the Model HZ-85 showing how dividers are used in a barrel to facilitate separate part processing.


SAMPLE PART PROCESSING PROGRAM. An essential step in determining the right equipment for your part is running samples in our process laboratory. Once we have your parts in-house, we’ll determine what type of media and processing times it will take to get your desired finish and return the parts to you for you evaluation. FEEDBACK IS IMPORTANT. You need to get back to us with information about the part finish results so we can make modifications to the process if necessary.

Discussion on MFI. History, process development, manufacturing operations and process development capabilities.


Mass Finishing, Inc's Technology director, Tommy Mathisen gives a demonstration of a three-step process in an HZ-60 Centrifugal Barrel Finishing machine Three step processing is used to develop highly polished finishes similar to what you would expect from jewelry. (1) Deburring and soothing (2) Fine smoothing and (3) Final Polishing.

This Model HZ-40 machine is popular among manufacturers of small arts in the jewelry, dental, medical and other small part industries. In this video barrels with plastic barrel liners is shown. This is useful for applications where there is a need to avoid part-on-part contact during the processing.

In this video an HZ-40 machine is used in a two-step process to first deburr and smooth and then burnish (brighten) parts. The burnishing process can be used in many part applications to strengthen parts against premature metal fatigue failure with centrifugally induced compressive stress.

This Model HZ-85 is being used to run a 3 step finishing process on machined orthopedic medical bone plate parts to first deburr, then smooth and highly polish these medical implant parts. Often times machines like this Model HZ-85 are used with barrel dividers to keep parts separate from each other during the process. In this particular process, the parts are being run in bulk.

In this video, an HZ-85 Model machine is being used in a single step to deburr and deflash clear plastic dental aligners. prior to the adoption of this centrifugal finishing procedure that type of edge finishing was being performed by hand in a tedious manual oeration.

This Centrifugal Barrel Finishing machine is typical of larger diameter machines. The largest machine available is an MFI HZ-330 machine with hexagonal processing barrels that are 12 inches in diameter and are 42 inches in length.
