Deburring machines are used in a variety of industries where metal parts are created. Often, these metal parts are created by mold or blanking systems that can leave sharp corners and edges. This ends up being a potential danger to workers that may be handling the parts later on in the production line. A quick solution to this is by using a metal deburring machine. Not only can this help reduce the overall production time and costs, but it can remove those potential liabilities from excessively sharp or dangerous components. Burrs can be formed of metal parts and components after they have been extruded and cut from a forming machine, punched or dye cut, or during laser or plasma cutting processes. Leaving these imperfections on the part can cause some issues during the construction and production process, as well as leave a poor looking product that consumers may not find appealing.
How Good is Good Enough?
Since there is no industry standard that says how much deburring is required on certain parts, it is up to the manufacturing plant as well as the finishing facility to make an educated guess. Burr-free parts can include those who have just been “dulled” around the edges and corners, to parts that have been completely smoothed or softened. Deburring machines make use of both belts and brushes to scrape away imperfections and reduce the knife-like edge of the metals. Additionally, you can find both wet and dry deburring processes. One of the positive sides of a wet machine is that there will be little to no dust produced. This eliminates the need for such strict eye protection and ventilation safety equipment. However, wet systems also require much higher maintenance and monitoring of the coolant mixes and lubricants. Dry systems are most common. However aluminum parts deburred on the machine may cause a potential fire hazard from the metal dust left behind. In the end, many manufacturing companies simply choose to send their parts to a company that specializes in finishing and deburring instead of investing in the machines themselves.
The Final Verdict
While metal deburring is ultimately the decision of the manufacturing company, the benefits it provides are many. Not only does it remove dangerously sharp edges and produce a smooth finish, but it also allows paint to adhere easier, reduces personal liability from worker injuries, and provides a shine that shows your consumers you care about the products you are offering.
