d unit and r unit Technology
Remove burrs from your sheet metal parts and grain with ease with the D Unit and R Unit technology.





Introduction to Deburring and Graining
In the world of metal fabrication, achieving a smooth and aesthetically pleasing finish is crucial. Two essential processes that play a significant role in this are deburring and graining. Mid Atlantic Global’s FINISHLINE Machine with the D Unit and R Unit is designed to excel in these areas, offering unmatched efficiency and precision for a variety of metal finishing needs.
What is Deburring?
Deburring is the process of removing unwanted edges, burrs, or protrusions from a workpiece after it has been machined. Burrs are tiny, often sharp imperfections that are left on the edges of metal parts after processes such as cutting, grinding, drilling, milling, or stamping. These burrs can not only affect the appearance of the product but also its functionality and safety.
Why Deburring is Important
- Safety: Sharp burrs can pose a risk to workers handling the parts.
- Functionality: Burrs can interfere with the assembly of parts and affect the mechanical operation of a product.
- Aesthetics: Removing burrs enhances the visual appeal of the metal surface.
- Quality Control: Deburring is essential for meeting industry standards and ensuring customer satisfaction.

What is Graining?
Graining refers to the process of creating a uniform surface finish on a metal part, often characterized by fine, parallel lines or patterns. This technique not only improves the appearance of the metal but also prepares it for further finishing processes like painting or coating.
Benefits of Graining
- Aesthetic Appeal: Creates a consistent and visually pleasing finish.
- Surface Preparation: Ideal for preparing surfaces for subsequent coating or painting.
- Corrosion Resistance: Helps in enhancing the protective properties of the surface.
