Ready to Send Your Sample Parts?

Running samples in our lab is the best first step in determining the right equipment and process for your part. We process most samples within a week, depending on the number of samples we’re currently working on.

Recommended Aerospace Finishing Equipment: HZ-Series

Most customers in the aerospace industry choose our High-Energy HZ-Series Centrifugal Barrel Finishing machines for their aerospace finishing and polishing applications. Our HZ-series machines are ideal for finishing critical parts like turbine blades in a one or two-step process. After tumbling, the blades are stress relieved and completely free of burrs and imperfections.

With our equipment, handwork is eliminated, allowing aerospace manufacturers to implement an aerospace surface finishing process that is efficient and repeatable.


  • Eliminate handwork
  • Reduced labor costs and production time
  • Remove machine lines and break sharp edges
  • Stress-relieve parts, ensuring part longevity and durability
  • Achieve a mirror-like finish on delicate parts
  • Ensure consistent aerospace surface finishing
  • Polish multiple parts simultaneously

Enhance Your Mass Finishing Process with the Right Media Selection

Media is an essential component in the finishing process and is required for the proper operation of any Mass Finishing equipment. Finishing media is carefully selected based on its composition, shape, size, and performance to optimize the efficiency and effectiveness of the finishing process.

In addition to the wide variety of media and liquid and powder compounds in our Media Store, we also manufacture our own corn cob blends at our manufacturing facility in Howard Lake, MN.
