Hand deburring and manual polishing are the bane of many machine shop’s and machining department’s existence.  What can be done to minimize the need for these tedious, time-consuming, labor-intensive production bottlenecks?  In many cases, the need for hand-deburring operations can be reduced greatly with high-energy and high-intensity isotropic finishing operations.  See below several examples below where laborious deburring procedures have been reduced or eliminated.

Precision Isotropic
Stainless steel castings often require substantial amounts of hand grinding work to smooth and polish surfaces.  In this case, all of the hand-work was eliminated by processing the parts with centrifugal isotropic finishing.

After Isotropic Micro-Finishing parts exhibit low micro-inch surface profiles.  The ultra-smooth surfaces improve bearing load, reduce friction, improve lubrication distribution, reduce operating temperatures and extend the service life of components. This type of processing is used extensively throughout the motorsports racing industry [Photo: Mark Ripley, BV Products]

brass coupling
Centrifugal Isotropic Finishing is used to smooth and polish these brass coupling components obviating the need for hand polishing operations.
Centrifugal Isotropic Finishing has been used to minimize hand smoothing and polishing for AM and 3D printed part applications.
Prior to the adoption of centrifugal isotropic finishing techniques small parts such as this required considerable hand-deburring or hand polishing to meet customer requirements.
Prior to using centrifugal isotropic finishing the machine shop making these parts had to handle each one individually through a series of hand deburring and hand-smoothing steps to eliminate machining marks on these medical parts that are used as a medical device inside body cavities
DENTALpart polished-cbf machine
Dental devices such as this one often required many hours of hand-work to make surfaces acceptable for patient use.  Much of that has been automated with the used of centrifugal isotropic polishing techniques.
316 ss casting
Prior to adopting centrifugal isotropic polishing techniques these stainless steel cast ornamental parts required substantial hand grinding and polishing

Prior to adopting high-intensity isotropic finishing methods parts such as these would be edge-finished, smoothed and polished by hand or manual procedures

architectural brass rails
Brass ornamental parts such as these were commonly hand-finished before isotropic micro-finishing processes permitted automation or mechanization of the smoothing and polishing requirements.
Prior to utilizing a fixtured isotropic micro-finishing process these types of musical instrument parts required substantial buffing operations.
milled pocket-001
Smoothing the machining/milling marks and step-overs in the pockets of this veterinary pharmaceutical molding plate posed several challenges.  When the machine shop used hand-smoothing methods to do this the surface tolerances were taken out of spec and parts were rejected.  A hands-free isotropic finishing method was devised that removed machining marks and left completely uniform smooth surfaces.

Parts with intricate geometries often require substantial handwork to access fine features and details, high-intensity isotropic micro-finishing makes it possible to use very finely divided abrasive and polishing materials for accessing intricate details.

Again, high-intensity micro-finishing permits fine edge and surface finish work to be developed for parts that might otherwise require manual methods for finishing.

Aerospace rotating hardware such as these parts can require enormous amounts of hand deburring operations which can be alleviated with high intensity dry isotropic spindle finishing methods.

Non-metallic parts such as these are often hand-finished and hand-polished unless isotropic finishing methods are adopted to automate the processing

These titanium orthodontic wire-forms are polished in special dry process media to produce highly refined and polished surfaces to go against the tender tissues to be found in the mouth.

Much hand-work has been replaced on the final surfacing of these acrylic and alloy dental components with centrifugal isotropic finishing

SS castings spoons
Isotropic micro-finishing was used to produce ultra-smooth polished surfaces on these stainless steel castings with a minimum of hand-work

Rough ground and sharp edged rotating components such as this can be deburred and finished with high-intensity dry spindle finish processing eliminating hand work that can produce significant reject and rework problems

Cast and Machined Alloy Steel Handgun Slides

Centrifugal isotropic finishing makes it possible to produce refined ultra-smooth surfaces in a hands-free environment.  An added plus is that these processes can produce surfaces that are particularly useful as substrates for a wide variety of coatings.


High-speed and high-intensity isotropic micro-finishing equipment makes it possible to add value to many manufactured components by producing high-quality surfaces often in entirely hands-free automated operations.
