Fast Turnaround on Metal Buffing Services

Halo Metal Prep specializes in all facets of buffing, benchwork and diamond finishing. We pay special attention to flatness, radius detail and final surface finish requirements. Whether it’s new tooling or reconditioning of existing tooling, our highly qualified bench men can get the job done quickly without the loss of precious production time.

Let’s break down what our Buffing services can do for you.

What is Metal Buffing?

Buffing uses a cotton, felt or sisal wheel with an added compound to achieve the desired finish: a shine or reflective surface. This process is usually performed last.

Diamond Finishing

Diamond abrasives are used for the hardest materials. Some examples of applications where diamond abrasives are applied are on tool steels, super-alloys and carbides. These are used in stamping dies, forge dies, plastic injection molds and optical tooling. These are amongst the most common industries that need diamond abrasives.


When a part cannot be held and manipulated to an abrasive wheel or belt, benchwork may be required with use of but not limited to handheld die-grinders, files and stones.

When preparing Dies for production you need the smoothest surfaces with the least amount of friction possible. We are some of the most experienced in the business in bringing these qualities out of your production dies. For this we will employ our years of benchwork experience to make the determination of what finish is required of the end-product, or follow the specifications lined out in your production drawings — Benchwork may be required to bring that last bit of desired mirror-like shine that machining cannot create on its own.

Examples of components that may require manual benchwork are: Molds, Dies, Aircraft Landing Gear, Castings, or heavy components that cannot be held by hand. Ready to get started? Request a quote below.

Applications of Our Buffing Services

We have specialist experience in servicing aircraft landing gear, metal faucets, Military Tank Components, Naval Components, Non-Ferrous Parts and more. Whether finishing is required to bring a product to market or whether prototypes are required for testing, Halo Metal Prep’s Metal Buffing Service will provide you with what you need.

Halo Metal Prep can work with Steel, Titanium, Magnesium, Brass, Bronze, Aluminum, Copper, Nickel, Inconel®, Monel® and more. If you do not have a callout specified, or need one applied, we can assist in producing a certified callout for your specific part.

Our ISO-certified buffing services can be applied to a wide variety of applications for your business that you may not know about. Examples include:

  • Anvil Resurfacing: In order to make sure your die cutting machine works properly, it is important to take care of the anvil as well as the dies. We can resurface the flats and radii of well-used and worn dies & anvil’s to get more use out of the part.
  • Machine Tooling: A machine shop’s ability to thrive is in part based on how well they care for their investments. The biggest investments a shop makes are in its people, tools and machines. To make sure your capital invested equipment lasts as long as it should, it is important to take care of all accessories and parts. We can help deburr and clean different parts of your machines in order to keep them running at maximum effectiveness and efficiency. Whether you’re looking for a reduced coefficient of friction on a piece of metal or a tighter tolerance overall finish we can provide for your needs.

Metal Buffing is a dying art. We are a pillar in the local industry and intend to keep the practice and tradition alive. Through 30+ years of experience we strive to differentiate ourselves not only through the quality of work but also through our customer service. Our ISO-certification signifies our work meets and exceeds industry standards and that we are dedicated to staying on time and on budget.

Precision Deburring

A manual process performed by trained and highly skilled operators on parts that require deburring only in specified areas and to close tolerances.

A common term used for this is benching. A mechanical process is usually performed using hand-held die grinders and a variety of special abrasives for both interior and exterior finishing on ferrous and nonferrous components.

Benefits to Precision Deburring include:

  • Edge radiusing for handling purposes or to meet the customers requirements

  • Exclusively addresses the area specified without affecting adjoining surface finishes or disturbing critical dimensions
  • Stress-relieving qualities are realized by removing stress risers that can cause cracks and lead to component failure
  • Not limited by the geometry of the part
  • Improves aesthetics
  • Helps with the functionality and smooth operation of working parts
  • Tolerances held within .001
  • Microfinishes held to customers specification
