Four barrels are mounted at the periphery of a
large turret. Each barrel is loaded with media, parts,
and water to approximately 50% to 90% full. During
operation, rotation of the large turret creates a centrifugal
force on the media and parts inside each barrel.
This force compacts the load into a tight mass, causing
the media and parts to slide against each other, removing
burrs and creating superior finishes.This action also
reduces the cycle time needed to complete the finishing
of the parts by up to a factor of 30 over conventional
vibratory and barrel equipment.

High intensity mass finishing methods can eliminate positively skewed machined surfaces and replace them with plateaued negatively skewed surface profiles
After high energy centrifugal finishing the surfaces are far more functional for the bearing application. More isotropic, more plateaued, more negatively skewed and have imparted a beneficial compressive stress. All of these attributes improving the load bearing and tribological properties of the part.
