Additional Services

Dearborn offers a large range of custom production capabilities to meet all your project requirements.

Dearborn can handle a variety of secondary precision machining services so you don’t have to manage multiple companies for a single project.

Our large range of custom production capabilities and partnerships allows us to meet all your product specifications and project requirements and eliminate the logistical headaches. No matter what precision machining service you need, Dearborn can provide it.

Dearborn, Inc. offers other services such as centerless grinding, passivation, anodizing, titanium anodization, chrome plating, dye penetrant inspection, splining, shot peening, laser etching, sawing and cadmium plating.

Centerless Grinding

Centerless grinding is an OD grinding process with the workpiece being supported on its own outer diameter by a rest, or stop, located between a high speed grinding wheel and a slower, smaller regulating wheel. Centerless grinding creates precise roundness and is able to improve out-of-round workpieces.


Passivation is the process where a material becoming passive, or less affected by environmental factors like air and water. In precision machining, passivation involves a shielding skin of base material, which creates an outer layer to protect against corrosion.


Anodizing is an electrochemical process that converts the metal surface into a corrosion-resistant finish. Aluminum is frequently anodized, as are other nonferrous metals such as magnesium and titanium. Anodizing is accomplished by immersing the material into an acid electrolyte bath and passing an electric current through it.

Titanium Anodization

Anodizing titanium creates a strong titanium oxide layer and is often used in the medical device and aerospace industries.

Chrome Plating

Chrome plating is a technique of electroplating a thin layer of chromium onto a metal or plastic surface, providing corrosion resistance, easy cleaning, or to increase surface hardness.

Dye Penetrant Inspection

Dye penetrant inspection is a inexpensive inspection method used to locate surface defects in non-ferrous and ferrous materials. DPI can detect casting, forging and welding surface defects, like hairline cracks, porosity, and fatigue cracks.


Splines are ridges (or teeth) on a shaft that interlock with grooves in a mating piece to transfer torque and maintain an angular connection between them.

Shot Peening

Machining can produce tensile stresses on workpieces that can lead to cracking or stress corrosion. Shot peening projects round media at the surface of a part, creating miniscule “dents” and compressive stress, which stops the fatigue cracks and stress corrosion that typically begin at the surface of the part.

Laser Etching

Laser etching permanently cuts an image or pattern into metal and can be used for logos, tracking codes, lot ID, manufacturing dates, and part numbers.


Dearborn can saw workpieces to create slots or grooves or to separate the workpiece into multiple pieces.

Cadmium Plating

A coating of cadmium metal applied over a base metal, usually for corrosion protection.
