Powdered Metal Parts Deburring

powdered metal deburring

At the beginning of 2020, sustainability showed up on the trends lists of almost every major industry. But sustainability isn’t just a New Year’s buzzword. Increasingly, sustainability is becoming an achievable goal for a growing number of consumers and companies. Never one-size-fits-all, sustainability is incorporated into multiple elements, from the food we eat to the clothing we wear. Sustainability is also a continuing commitment in the manufacturing industry.

Working toward such a goal is easier when looking at the bottom line and there is a natural reason to emphasize the reduction of unnecessary waste. Therefore, manufacturers are always looking for ways to make their processes more efficient throughout the supply chain. One tried-and-true aspect of sustainability includes the use of powdered metal deburring on powdered metal parts.

Adaptable and Versatile

Powdered metal parts are an important part of the manufacturing landscape and because of varying levels of strength of greenware used, some options may be sturdier than others. When part strength is critical, consider the use of powdered metal deburring. The reliable process uses compacted metal powder that’s sourced from some of the sturdiest elemental metals. Heat at just below the point of melting joins the metal powders into a cohesion of strength. The use of powdered metal is preferred by manufacturers because it produces very little scrap metal waste. The reduction of waste supports comprehensive sustainability measures and offers versatility of design.

Although the use of powdered metals offers versatility, there are some issues in the process that CDMC set out to improve. The low profile of powdered metal parts requires deburring to remove burrs on both faces. Machines of the past employed nylon disc brushes, a method that required operators to use their hands to flip the object to its opposite side. With such a method came human error, which resulted in a loss of time and resources.

A Better Way

CDMC understood there was a safer and more efficient way to deburr these critical pieces. In response, the company created the Mag Series and the 4000 Series deburring machines to reduce downtime, boost optimization and improve consistency of operations.

Mag Series – Through-feed, in-line deburring machines are ready to tackle the high production of flat parts in need of deburring on both sides. Parts are conveyed using a series of magnetic conveyors and are available in 2-, 4- or 6-head platforms and in Mag T versions.

4000 Series Green Powder Deburring Machine – Adaptable through-feed deburring machines deburr parts on opposing sides and brushes offer simultaneous two-side deburring to accommodate almost any infeed/outfeed orientation, also available with OLS’s exclusive Auto Amp Compensation system.

Why the Pharmaceutical Industry Should Have a Deburring Process


Accuracy is critical in many industries but in the pharmaceutical industry, accuracy or lack thereof can easily be a matter of life or death. As a result, manufacturers in the industry must have machines and parts that are accurate and dependable. Anything that’s produced on these lines must be predictable and repeatable. Those in the industry know that even the smallest alteration being off spec has the potential to produce disastrous results. As the scale of the operation grows, these tenets become even more important.

The resulting margin for error is often small. A change in calibration or quantity, a small burr or an irregularity in a part, gasket or fitting could all spell trouble. Any one of these things might be the cause of a leak, mismeasurement or an even larger problem that could completely stop production on the line. While a production stop is not good in any industry, it’s downright dangerous when experienced in the pharmaceutical industry.

Many of the pharmaceutical products produced are time-sensitive and an unexpected delay could mean an entire batch needs to be thrown away, an unfortunate waste of time and money. Not to mention how a leak or mix that’s not kept sterile could endanger workers in the process. Therefore, quality deburring machinery is an important asset to all manufacturing processes. Having reliable deburring equipment in place can add an additional layer of safety for the pharmaceutical manufacturers as more and more take on the work of medical-grade components.

A Reliable Deburring Solution is Important to Manufacturers

When looked at in isolation, a thin raised ridge or a spot of roughness might seem like no big problem. With caution, these areas could be worked around and those dealing with the product could be extra cautious. What’s not considered is how a raised edge or rough area has the potential to compromise the productivity of a manufacturing line as well as jeopardize the safety of those working the line.

Deburring Solution

Therefore, finding a reliable deburring solution is so important to manufacturers. Deburring is a proven process to eliminate thin ridges from a variety of metal materials as well as eliminate rough spots and burrs that can cause damage to a machine and a human. Cleveland Deburring Machine Company (CDMC) offers several deburring solutions to manufacturers and markets.

Deburring Needs

With the ability to build and configure deburring machine solutions for next to any application, CDMC recommends beginning your needs assessment by looking at some of the standard deburring practices such as gears, sprockets, powdered materials and fluid power parts. Once initial needs are determined, CDMC can help tailor a deburring solution to the exacting requirements of each customer.

Standard Deburring Practices

Fluid Power Parts are available in many sizes and shapes. These components include gearmotors, pump housings and pump gears. When considering a deburring practice, it’s important to consider the parts from many angles. To meet these varying angles, the deburring process must apply consistent brush pressure. This ensures the multi-faceted parts receive adequate preparation on all sides as well as above and below.

Gears are an essential element of machines. The use which dates back into the third century with applications by Greek mechanics. Consistent usage of gears creates burrs. This is true for several gears including a parallel axis gear, a ring gear, bevel gear or a pump gear. Use creates wear and a deburring process, used consistently, can keep gears functioning effectively for the long-term.

Powdered metals are metal parts not yet exposed to the sintering process. As a result, this fragile greenware demands care in handling and deburring. Powdered metals also cannot be magnetized during any part of the pre-sintering process. Do not fear! CDMC is here to help with special needs. We have deburring solutions ready to accommodate any special handling requirements and output needs.

Sprocket is a loose definition for any wheel form possessing radial projections. These offshoots help engage passing chain, track and tread. Applications for sprockets are large and small, from massive tanks on the battlefield to luminous film passing through a projector. CDMC can meet demands for sprocket deburring throughout the automation and manufacturing industries, offering solutions for sprockets on both faces and multi-row sprockets, too.
