Industrial, Commercial, Custom, and Aerospace Metal Polishing, Line Graining and Metal Buffing Services

Available metal finishing and metal polishing for all industrial & commercial requirements including aerospace and medical finishing and manufacturing.

We polish all metal alloys, including stainless steel, aluminum, titanium, and copper alloys, as well as plastic.

Our dedicated staff with state-of-the-art equipment allow us to offer you an extensive variety of metal finishes:

  • Grinding: basic stock removal using either stone or coated abrasives.
  • Metal Polishing: mirror finishing
  • Jitterbug Finish, orbital sanding, and DA sanding finishes
  • Line Graining: a directional scratch pattern using coated abrasives.
  • Stroke Sanding: a means of flat sanding for large, long, or heavy items.
  • Brush Finishes: a semi-directional pattern using coated or woven abrasives.
  • Buffing: an operation accomplished by working the substrate with cotton or sisal wheels with an application of cutting compound. This usually follows a belting (or polishing) operation.
  • Color Buffing: a final cleaning and brightening operation that uses soft cotton wheels with an application of rouge. This usually follows the operations mentioned above.
  • Burr Bench: any number of detailing operations (performed either by hand or with a bench tool). Examples include light grinding, filing, fine detail buffing, de-burring, and I.D. metal finishing.
  • Special Finishes: unique finishes ranging from a simple jitterbug finish to an intricate, custom patterns on most metals. Stainless steel, steel, and, aluminum finishing.
  • Ra. Testing: testing the surface roughness or texture of an item, using a tool that scans the surface of said item and reports the Ra. (roughness average) in micro-inches or micro-meters as described in note #4 on most blue prints. Ra.=AA=CLA Ra. finishing, #4, #6, #8 finish

Tube Polishing Service

the capability for industrial and commercial tube polishing of all types of metal tubes in any size, shape, and material to virtually any finish internal and external tube polishing. Low to High volume, extra large tubes to small sizes.

Tubes Polished to various grits or/and finishes ID or OD (inner and outer diameter polishing)

  • Polishing of satin finishing- #3, #4, #5, #6 and #7 finish
  • Polishing of Bright finishing- #8 finish or mirror finish
  • Polishing of Ra finishing- Roughness average measured with a profilometer

Satin finish on metal tubes, both round or square, can be polished in either linear/ long grain and we can polish grit lines in the short grain, circular, or annual grain

Tubes of various shapes and sizes (square, round, rectangular tube polishing) can be polished on the ID or inner diameter, to virtually any finish and can polish to any Ra (roughness average) as needed. We have the ability to polish the ID of just about any size diameter, up to but not limited to, 23′ in length!

We provide metal tube polishing with semi-automatic tube-spinner, polishing and grinding machine. This machine can help achieve more consistent finishes, with less man power, while accommodating sizes up to 8″ inch diameter and around 20′ lengths.

Ultrasonic Parts Cleaning Service & Metal Finishing

Ultrasonic parts Cleaning service before metal finishing: a process in which items are immersed in an environmentally safe aqueous solution that has been excited by sound imitating transducers. The sound waves in liquid provide the cleaning. Our clients are thrilled with the results!

Commercial and industrial precision parts cleaning with Ultrasonic parts cleaning systems perform best in cleaning parts that are intricate and easily damaged by other cleaning methods. For example, a small part or assembly is ideally suited for ultrasonic cleaning before the metal polishing or metal buffing project starts. Intricate parts can be easily cleaned without damage. Also, cleaning of parts that require high cleanliness for a long life. Any parts or components that require

a high cleanliness standards for optimum performance, and will not tolerate any dirt residue.

Ultrasonic Parts Cleaning Service Process

The ultrasonic process is well suited to aqueous cleaners. As such, ultrasonic cleaning provides an environmentally friendly alternative to mineral spirit cleaners and chlorinated hydrocarbons.

Our knowledgeable staff is dedicated to giving you superior ultrasonic cleaning for buffing and metal finishing services from start to finish. We look for opportunities to go beyond the normal scope of metal polishing.

Line Graining, Satin Finishing, Metal Brush Finishing, Time Saver Finishing

A line grain finish is a scratch or sanded, linear pattern, used to remove or minimize scratches, material defects, mill scale and porosity. Then a pass to leave a uniform finish. Buds Polishing has the ability to apply satin finishes, brush finishes, and/or line grain finishes, on various metals and even plastics! We can achieve these brush finishes or line grain finishes by our 9′ sand stroker, 2 time savers (25″ AND 52″), our semi-automatic tube-spinner, and even manually by hand. These finishes are suitable for jobs large or small; custom or production.


Grits used can be anywhere from 36 grit up to, but not limited to, 600 grit. Though, 80-220 grits are most commonly used. Abrasives used range from aluminum oxide, zirconia, scotch bright/non-woven, and silicon carbide. Line graining is usually used on and best suited for flat/sheet type shapes. However; line grain, satin or brushed finishes can also be applied to castings, billet/machined, and small or large parts.

These finishes are great for hardware, fabricated parts, aerospace components, automotive pieces, food processing or sanitary surfaces, appliances, hand rails and elevators. Line graining on cylindrical, tube or round pieces can be achieved with the grit lines going in annual/short direction, longitudinal or long direction; in the inner and outer diameter as well. See our Tube Page Please ask for details on specific sizes or shapes.

Buds Polishing can also touch up and blend items that have been welded to hide effects of weld discoloration, and blend direction of grain lines. We can also show grain lines in a “miter” to showcase designs on corners or 90 degree angles.

Special note how to: most items that are to be welded or fabricated should be polished or line grained BEFORE fabrication, then touched up after. This usually cuts cost, improves quality of finished product.

Also, a line grain, satin, or brush finish is usually 1/2 the cost of a bright or mirror finish if you are on a budget.

List of the Unique Metal Line Grain Finishes offered at Buds Polishing

Also known as grinding, roughing or rough grinding. These finishes are coarse in nature and usually are a preliminary finish applied before manufacturing. An example would be grinding gates off of castings, deburring or removing excess weld material. It is coarse in appearance and applied by using 36–100 grit abrasive.

When the finish is specified as #3, the material is polished to a uniform 60–80 grit.

Also known as brushed, directional or satin finish. A #4 architectural finish is characterized by fine polishing grit lines that are uniform and directional in appearance. It is produced by polishing the metal with a 120–180 grit belt or wheel finish and then softened with an 80–120 grit greaseless compound or a medium non woven abrasive belt or pad.

This finish is commonly used for the medical and food industry and almost exclusively used on stainless steel. This finish is much finer than a #4 architectural finish. One takes great care to remove any surface defects in the metal, like pits, that could allow bacteria to grow. A #4 dairy or sanitary finish is produced by polishing with a 180–240 grit belt or wheel finish softened with 120–240 grit greaseless compound or a fine non woven abrasive belt or pad.

Also known as a fine satin finish. This finish is produced by polishing with a 220–280 grit belt or wheel softened with a 220–230 greaseless compound or very fine non woven abrasive belt or pad. Polishing lines will be soft and less reflective than a #4 architectural finish.
