A problem that manufacturers have faced for many years is the common burr that appears on products after they have been cut, drilled, pressed, or molded. The presence of burrs requires that the workpiece be finished by being deburred, which includes some form of grinding, polishing, or sanding. Read More…

Burrs are also common place in the production of tubing and appear on both the inner diameter (ID) and the outer diameter (OD). With most deburring, burrs are removed from the surface of the workpiece to give it a smooth even finish. This is also true of tubing with the additional need to remove burrs from the interior as well as the exterior of the tubing.
What is Tube Deburring Machinery?
For many years, deburring of tubing was performed by hand using some form of an abrasive tool such as a wire brush or file. The hand method resulted in uneven, rough surfaces that required significant after processing adjustments. With the advent of motor driven grinding machines, a new form of deburring took shape in the form of tube deburring machinery.
Most tube deburring machinery has the workpiece inserted into the machine where it is ground and smoothed. The advantage of tube deburring machinery is the evenness of the deburring and the smoothness of the finish. Both the ID and OD are deburred leaving a flake free uncontaminated surface.
The process used by tube deburring machinery is similar to having hundreds of tiny pieces of sandpaper pummeling the burrs. The process can be completed using automated machinery or manually operated ones. Either method is widely used.
Types of Tube Deburring Machinery
All tubing has to be cut to lengths that meet the needs of an application. In some cases, tubing may need to be cut several times to be properly shaped. One issue with tube cutting are burrs, which appear as tiny sharp flakes on the inside and outside of the tubing. Before the tubing can be fabricated by bending, beading, or swaging, the flakes, or burrs, must be removed.
Tube deburring machinery removes the burrs from the ID and OD and smooths the end of the tubing, giving it a fine even finish. Once deburred, it is ready to be bent, flared, or reduced.
The tools used for deburring tubes varies according to the density of the bristles and the type of tubing to be deburred. Plastics require a gentler approach while tubing made of steel, or stainless steel, necessitates a more aggressive approach. In either case, once the deburring machine has completed its processing, the tubing is ready for further fabrication.
