The Innovations of Powdered Metal Deburring

The importance of sustainability and the reduction of unnecessary waste is an important topic to manufacturers and the customers they serve. As a result, smart manufacturers are continually on the lookout for ways to make processes more efficient for everyone involved. One method that continues to show its usefulness is the process of powdered metal (PM) deburring on PM parts. The powdered metallurgy process uses compacted metal powders from some the strongest elemental metals to form parts. Heat applied just below the melting point joins the metal powders into a strong mass.

Versatile Applications

There are many reasons manufacturers prefer PM, including little scrap metal waste, its sustainability and design versatility. The flexibility in applications for powdered metal parts can create an issue of its own. Because of the low profile of the powdered metal parts, each part requires deburring on both faces to remove burrs. In the past, powdered metal deburring employed nylon disc brushes. This method relied on operators to hand flip the deburring to the opposite side. As with any human-based operation, errors can occur, resulting in broken parts and a loss of important time and resources.

The Powdered Metal Deburring Solution

In response, Cleveland Deburring Machine Company created the Mag 4×2 inline deburring machine for powdered metal deburring. The deburring machine has two production platforms and incorporates three magnetic conveyors. Powdered metal parts receive deburring from two nylon brush heads that rotate in opposite directions. A second conveyor deburrs on the opposite face from below. The third conveyor passes each powdered metal part through a demagnetizer below conveyance to a sintering furnace. Repeatable deburring results translates into reduced downtime, improved optimization and better consistency.

What is the Deburring Process?

deburring process

At the Cleveland Deburring Machine Company (CDMC), we’re regularly speaking to members of the manufacturing industry about their processes, their product outcomes, and their needs. Many of them are refining their processes to reach greater quality standards, some are trying to improve their processes to re-attain a quality level they’ve enjoyed in the past. But, for almost all of these clients, we’re hearing about a need for deburring along the manufacturing line. Fortunately, here at CDMC, that’s exactly what we do.

The deburring process, for those who aren’t familiar, is a process that removes built-up burrs and other imperfections from a finished surface. A burr is a ridge or area of roughness produced during the cutting of metal parts or materials. In some cases, burrs are created in cutting plastic parts or materials as well. The problem that burrs create stems from their build up. When a machine part becomes “impacted” by a build-up of burrs, the end-product coming off that machine can suffer quality issues. As anyone in the manufacturing industry can imagine, rough edges on a piece of metal that is meant to be combined or joined with another piece of metal is going to negatively impact the seal or the edge or corner of the finished product. In short, rough edges don’t form a perfect joint when fitted together. Burrs can also create a plating build-up on edges, or, in some cases, edge fractures in certain kinds of materials. This, of course, can be a serious issue when the end product is meant to hold up well under stress, strain, or pressure. Fortunately, much can be done to eliminate the presence of burrs in manufacturing, saving product quality, reducing waste, and improving finished product numbers. Deburring is one of the solutions.

Some have asked about the deburring process, how it’s accomplished. We’ve engineered and built deburring solutions to meet the needs of numerous manufacturers in a wide variety of industries and markets. And, although each solution is often tailored to the needs of the client, the deburring process is much the same.

We have a number of deburring machines on hand to perform a wide variety of different processes on common types of gears, sprockets, and similar machine parts. In developing a solution, we know that certain variables – such as cycle times, part sizes, loading, and other specific limitations – must be considered. The processes developed by CDMC often allow for brushing and deburring on both sides of each part as it passes through the machine. In some cases, the parts are fed to the machine manually. In others, robotic loading is employed. Some machines make use of a magnetic conveyor belt (each part can be subsequently demagnetized as it exits the machine when needed). In the end, the process offers a consistent, reliable, and repeatable deburring to the part that is fed to the machine.

Unique Deburring Applications

As a company of highly-experienced designers, engineers, and manufacturers of deburring equipment, the Cleveland Deburring Machine Company (CDMC) has enjoyed a long history of working with clients in all areas of manufacturing and creating some of the best deburring solutions for nearly any application.

Over the years, we’ve designed and developed a number of deburring and metal finishing methods and created a line of truly competent deburring machines. Never satisfied with the status quo, we’re always redesigning and improving our work. Through the use of robotic loading, our deburring machines are able to take a large amount of work off the hands of employees who, in the past, had to manually feed and flip each part before the nylon brushes could do their work.

Another benefit to working closely with our clients and listening to their needs, is that we’ve learned to use our talents and our deburring know-how to create a number of unique deburring applications for a wide range of markets. To address material removal and stripping, CDMC has designed and built equipment that can strip friction material from steel backing plates. We built an operator-loaded deburring machine that makes use of a single wire brush to remove 1/16″ thick material (in a one inch width strip) from a 12″ disc in about sixty seconds. The internal coolant for this specialized machine keeps the brush and the parts from overheating during the material removal and stripping process. The machine can be easily integrated with auto-loaders if the need is present.

One of our unique deburring applications came from a request by a client in the semiconductor manufacturing industry who required a process that would create a precision-honed and highly-polished surface on fluid fittings. Each of these fittings would be used to transport gases in potentially-volatile atmospheres. Leakage was a primary safety concern. CDMC was able to deliver a solution to the client that made use of a variety of media. The resulting process was one in which each fluid fitting was honed and polished on multiple surfaces. The process required six stages but worked beautifully.

Another unique deburring application developed by the team at CDMC is for the aluminum finishing market. One of our clients asked us to design and develop a process that would expertly apply a brushed finish to aluminum sheets. The brushed aluminum sheets were subsequently punched and stamped to make front-load washing machine doors. Even though the output requirements set forth by the client were fairly small in scale, the process had to be exact and uniform from one piece to the next. CDMC developed a solution for this client that involved a brush platen fitted with six 4″ nylon disc brushes. Each aluminum sheet is loaded by hand. Afterward, the sheet is advanced to a position where it is secured by a vacuum table. When the sheet is in position, the brush platen lowers, and a brushed finish is produced inside of a four-second cycle time.

At CDMC, we strive to provide the most cost-effective deburring solutions, and the best customer service in the industry – whatever your unique application need may be. Contact us today with your deburring application needs and we’ll show you what we can do.
