DEBURRING:

The Devil’s in the Details

A significant amount of the exchange that takes place between machined part manufacturers and their customers relies on trust. We trust that the parts we purchase will function as advertised, and at the very least not harm our existing equipment. However, subtle yet essential finishing processes can make or break your productivity, and not every machine shop or parts manufacturer operates under the quality control standards necessary to keep your technicians safe and your equipment functional. When it comes to deburring the sharp edges and irregularities in machined parts, settling for subpar can have serious consequences.

DO YOUR DEBURRING HOMEWORK Whether you run your own in-house parts machining operation, or order your parts from another manufacturer, there are steps you can take and questions you can ask in order to ensure the proper deburring of the parts you use and sell. According to Erik Atkinson of P.D. Peterka & Associates, a machine shop based in Saukville, WI, deburring is usually done by hand, but there are a growing number of automated deburring machines out there. Though sanding down sharp edges seems like a simple process on face value, manual deburring requires significant skill and technique in order to remove just the right amount of material without damaging the part itself.

Here are a few of the deburring proecsses that keep parts appropriately smooth: • cutting processes • power brushing • bonded abrasive finishing • abrasive blasting • abrasive flow deburring

Cutting processes and power brushing, also known as sanding, are some of the most common deburring methods, while methods like abrasive blasting are considered precision and allow for part tolerance to be maintained. Automated deburring, or mass finishing, is sometimes offered by machine shops and is accomplished via barrel tumbling, vibratory finishing, or spindle finishing. Before finalizing an order, it’s generally good practice to inquire with the parts manufacturer on what kinds of deburring methods are used there, and whether or not they are ideal for your application.
