What is Chamfering and How Does it Differ from Deburring?
Tuesday, October 23, 2018

Chamfering


A chamfer is known as a 45 degree beveled edge that is built into a number of designs, such as architectural and technological products. For instance, chamfering may be employed in circuit board technologies, particularly where a 45 degree edge provides the right result.

A pertinent example of chamfering in the design aspect of major hardware is in the construction phase of Apple devices. Certain editions of Apple’s hardware are comprised of a chamfered edge on the perimeter of the gadget. This deliberate edge adds to the aesthetics of the device.

The Difference

Chamfering and deburring are two terms that are used in the fabrication process. They describe procedures for finishing machine parts specifically. Chamfering includes creating a bevel, groove and furrow.

Furthermore, deburring entails removing any and all rough ridges and edges in the aftermath of the shaping process. While manual finishing remains a popular technique, manufacturers are inclined to use automation since the use of machinery diminishes costs and the outcome is generally more consistent as well.

Objective

The purpose of both chamfering and deburring pertains to the finishing process specifically. This is when the excess material that is still attached to the metal after its fabrication is complete. Naturally, finishing represents an important phase overall.

It ensures that the parts are as per the specifications of the product. Deburring separates pieces of metal and the imperfections that may impede the functionality of a particular part. This is imperative since such parts may unfasten during operation and cause detriment to other parts and even incite injuries to users. Moreover, the process of chamfering is used for enacting symmetrical and uniform grooves in the teeth of the specific gear.

Finishing

Like we alluded to earlier, finishing by hand using oscillating equipment or a spindle grinder and the filing and brushing process are frequently used. Since both chamfering and deburring can become labor intensive, they may augment the total cost of labor. This means that the final cost of the product also goes up.

However, a caveat attached to hand finishing is that it does not guarantee precision in terms of the finished article. Accuracy and consistency may be hard to achieve, until and unless users are extremely careful. Also, if the parts of the product are not in accordance with the specifications of the project, then modification by hand can be a tiresome experience.

Edge Finishing

The degree of finishing varies on a case-by-case basis and it is left to the manufacturers to decide what degree of finish is required. For instance, edge finishing is comprised of seven levels that include the removal of sharp edges, unfastening of burrs that are clearly noticeable and calculated chamfering as well, among others. In this case, a chamfer is measured as a dimension and an angle also. This is determined by the specifications of the project.
