The metal finishing experts guide to Cross hole deburring

What is cross hole deburring?

Cross-hole deburring refers to the process of removing burrs or sharp edges from holes that intersect or cross each other within a workpiece. These holes are commonly found in machined parts or components and can be challenging to deburr due to their intersecting nature.

Cross-hole deburring is essential for several reasons:

Functionality: Burrs within cross holes can obstruct the flow of fluids, interfere with the insertion of pins, or affect the proper seating of mating components. Removing these burrs ensures smooth operation and functionality of the finished part. This is especially true in industries such as oil and gas.

Safety: Burrs within cross holes can pose safety risks, especially in applications where the workpiece is in contact with human skin or other materials. Removing the burrs helps eliminate sharp edges and reduces the potential for injury or damage.

Quality and aesthetics: Deburring cross holes enhances the overall quality and appearance of the finished part. It eliminates unsightly imperfections. Furthermore it ensures that the part meets the required specifications and standards.

There are several techniques used for cross-hole deburring, including:

Manual deburring

Manual deburring: This involves using handheld deburring tools such as deburring blades, brushes, or abrasive stones to carefully remove the burrs from the cross holes. It requires skill and precision to ensure proper deburring without damaging the surrounding areas.

Machine-assisted deburring

Machine-assisted deburring: Specialised deburring machines or equipment can be used to automate the cross-hole deburring process. These machines may employ various methods such as rotary filing, abrasive blasting, or brushing to remove the burrs efficiently and consistently. Therefore, choosing the best method for your requirement is wise, in order to save time and achieve the best finish in the future.

Mass Finishing

In some cases you may have several parts in which you need to get into the cross holes. Therefore, it might be worth exploring mass finishing. Our customers have used magnetic deburring machines or vibro bowls. We can organise trials and samples for you.
