Metal Finishing For Manufacturing

OEM Custom Metal Surface Finishing

General Aviation, Commercial Aircraft, Aerospace Defense, Aircraft Engines

Manufacturers, machinists and fabricators send us their injection molded, stamped, machined, cast or welded parts and we remove existing burrs, residue, flash and rough particles from the parts. Our centrifugal barrel finishing machines work the parts by applying up to 30 G’s of force against the selected media and parts. By adjusting the speed and duration, as well as the abrasives, polishing compounds and other additives, we can accurately and repeatedly control the level of material removal.

We are experts in developing customized finishing programs for all your parts or components. From simple deburring services to high-end titanium finishing, our combination of specialized tumbling media and centrifugal polishing expertise fill the finishing gaps in your overall part production process.

What We Do

From simple deburring and deflashing to complex multi-step polishing and micro-surface finishing, we have the finishing process to complete your project. Our short lead times, versatile processing experience, repeatability and attention to detail ensure the on-time, high quality parts our customers demand.

Custom Development Strategy

There is no magic here—it’s precision. We customize each finishing process to fit our clients’ needs from start to finish. At the end of the day, we specialize in you. Our centrifugal barrel services are ideal for parts from 3mm³ to up to 9” x 9” x 41” and are custom tailored for each specific component.

Samples & Quality

We formulate a process for each product and provide our clients with finished samples at no charge. Collaboration with the customer is key. If something needs improvement, we’ll use the client feedback to adjust the process—not the standard. The result is a customized, consistent, and repeatable set of specifications for finishing your unique product.

Advanced technology

We continue to add state-of-the-art machinery, media and inspection equipment to adapt to the industry’s latest advances. Our methods have exceeded expectations by providing a better polishing quality and faster turnaround times than are typically possible in-house or as an outsourced operation.

OEM Custom Metal Finishing

Original equipment manufacturers, or OEM’s as they are called, manufacture and supply individual parts, services or assemblies used in their own or another companies finished products. The speed, diversity and logistics of today’s manufacturing environment has made OEM’s a vital link in the supply chain especially for unique, specialty or custom work.

Many OEM’s may be experts in a specific field of manufacturing, like laser cutting or engraving, but may contract out other items like welding, painting or custom metal finishing. Ultimately, if the OEM agrees to supply the finished assembly, it is their responsibility to make sure the contracted outside processes being done, meet all detailed specifications set forth by the end customer.

ISO Finishing has worked in tandem with many different and diverse OEM’s in matching the type of finishing services best suited for their specific application, including custom metal finishing.

Custom Metal Finishing to Exact Specifications

At ISO Finishing we pride ourselves on offering certified precision custom metal finishing services to our OEMs. The manufacturing industry demands short lead times while providing accurate and precise finishing solutions. We offer the shortest lead times in the industry. Our fast turnaround times and reliable customer service make us a leader in the surface finishing industry. Our experienced on-site engineering and customer service teams will ensure ISO Finishing delivers a product we are proud of every time.

Our Services

Centrifugal Barrel Finishing

Barrel tumblers work well for jobs requiring heavy burr removal. Centrifugal barrel finishing machines are also good for burnishing, rapid radiusing of edges, and heavy deburring. Removing excess material or polishing parts, remove burrs, improve surface appearance, polish and clean are all possible using centrifugal barrel finishing equipment.


In the manufacturing world, deburring refers to various methods used to remove burrs, the residual rough edges or protrusions left behind after a part is produced. Burrs can affect the surface quality of manufactured parts produced where performance, safety, and appearance of a part is concerned.


Deflashing is the process of removing residual aluminum, titanium, or stainless material used in the manufacturing process. The deposition of small bits of residual material called “flashing” may appear in each part. The particles can be removed using a centrifugal barrel machine for a fast and cost-effective method of removing any residual particles.


Our passivation of stainless steel system has been designed to offer our customers a one-stop solution tailored to meet the stringent ASTM a967 specification for the cleaning, testing, and passivation of stainless steel, titanium, and other metallic parts. Our relationships with local and national medical manufacturers and our expertise allow us to be a true value-added solution in passivation services to our customers finishing needs.


The presence of burrs, parting lines from castings or other surface imperfections affects the adherence, continuity, and general durability of plated materials. Metal surfaces often require polishing and buffing prior to decorative plating. ISO Finishing understands the importance of pre-plate finishing. Polishing is not only used to enhance the appearance of a part, but it also helps prevent contamination of instruments, remove oxidation, create a reflective surface, optimizes performance and can prevent corrosion in pipes. When it comes to machined parts, smoother is better for reducing heat and friction.


Radiusing is a type of deburring that entails the removal or rounding of sharp part edges formed during the medical manufacturing process. Parts with sharp edges can be radiused to pre-defined specifications using centrifugal barrels, vibratory bowls and centrifugal disc machines.

Ultrasonic Cleaning

Ultrasonic cleaning is an environmentally friendly alternative to the solvent based cleaners previously used. Ultrasonic cleaning uses high frequency sounds waves, those beyond the range of normal human hearing (18 kHz), and an appropriate cleaning solvent to remove contaminants from parts. The ultrasound can be used with just water or be combined with surfactants to gently remove residual cutting oils and microscopic chips.
