Since the metalworking industry has a wide variety of finishing requirements and an equally wide range of products to be finished, the efforts necessary to accomplish the desired results demand increasing degrees of specialization. Equipment that meets your precise operating needs is crucial to satisfying the specific output standards for the final product.
The spindle concept is sometimes referred to as a Slurry Deburring Machine or Flowing Abrasive Machine. The equipment generally includes a circular rotating tub holding loose media/abrasive, a rotary spindle to hold parts and fixturing.
The principle of this process is to use slurry deburring to finish a workpiece mounted on the rotary spindle by immersing it into a rapidly moving abrasive slurry. The velocity of the abrasive is generated by the rotating tub speed suitable for the process requirements. The abrasive slurry particles swiftly flow over and through holes and rough edges, removing sharpness and burrs.
If you’re new to doing your own surface finishing, you may be confused about the different types of media available, particularly the role of plastic tumbling media. In what situation would you use a plastic rather than something like steel or ceramic media?
Plastic media came about to finish softer metals/alloys. Processing softer metals (i.e. aluminum, brass, bronze, etc.) The other media are heavier per cubic foot, then the concern is rolling over the burr and peening against the surface. Much harder and longer cycle times are needed to remove a peened down burr. If the burr is a parent metal it would not be a burr as identified with vibratory finishing/deburring.
If your industrial products are mostly tough steel, cast iron, and stainless products, you may want to try using a ceramic bond. However, plastic tumbling media can be just as aggressive as ceramic and even faster with cutting. The issue then is the attrition rate or rate that the media wears away. It is more costly, wears faster, and has more residue to deal with, but can provide a very nice surface profile and RA/RMS. There can be safe scrubbing action to remove deposits and build upon a plastic part surface. Deflashing or deburring plastic is a different story. All pre-made tumbling media is manufactured to wear away at a certain rate (attrition rate/how long is going to last in the machine?). The faster it wears away to more waste is generated from the process.
What Are the Benefits of Using Plastic Media Blasting for Your Parts Finishing?
The main advantage of using plastic abrasive blasting media is that it’s easier on your more sensitive surfaces and does not change the original metal surface profile under the paint.
Benefit: Not having to refinish the metal substrate prior to repainting. The finer the surface substrate with the finish the better the paint quality/appearance with the end result. The four types of plastic blasting media. Acrylic, melamine, polyester, and urea. All have their advantages and applications. The plastic media blasting process is a dry process, meaning no warping, pitting or flash rust. Dust collection is so very important today. The right collectors are needed for any blasting process. Plastic media blasting does have some special features over a standard blast unit to be able to move abrasive through the system without them clogging up. Plastic media blasting is very susceptible to moisture build-up.
Ultrasonic cleaning systems rely on transducers to vibrate a submersion tank, creating ultrasonic waves so small they’re difficult to see. The ultrasonic waves create microscopic cavitation bubbles that implode, creating latent heat and energy. The energy removes buildup, ensuring a quick, thorough clean every time – even for thread roots and other complicated contours.
Ultrasonic deburring is using the same technology to accomplish a slightly different goal. Here, the ultrasonic waves round off and remove rough edges, known as burrs, left behind by machining processes to make the pieces look and feel smoother. Ultrasonic cleaning and deburring may be accomplished simultaneously.
How Ultrasonic Cleaning Differs From Other Methods
An ultrasonic cleaning system can combat some universal production problems. Here are just a few:
Cleaning by hand is time-consuming, and the level of accuracy varies from person to person.
If the item is being coated, bubbling and flaking can occur after application if the surface wasn’t cleaned thoroughly.
When an item isn’t up to cleaning standards, it can hold up an entire production line.
Ultrasonic cleaners require no harsh chemicals, making them efficient and environmentally safe alternatives to scrubbing items with abrasive and potentially harmful cleaners. Often, a simple, mild, or ultrasonic detergent will do. You can adjust the ultrasonic cleaning system to the water temperature and frequency needed for the parts you’re cleaning and use various cleaning agents.
What Are the Benefits of Ultrasonic Cleaning?
There are several ways an ultrasonic cleaner can improve workflow and maximize production, including:
Reduced time spent cleaning parts: Cleaning with an ultrasonic system typically takes 10 minutes to an hour, depending on the item’s size and whether it needs to go through a multistage process.
A longer-lasting, near–perfect finish: Reducing surface debris acts like a first line of defense for a long-lasting topcoat. Ultrasonic cleaners can reach holes and cracks that manual cleaning processes may not touch. You can add ultrasonic detergents or other cleaning agents to remove tough greases and other contaminants, too.
Cost-savings and return on investment: Fast, efficient cleaning processes make for productive production lines. Ultimately, this system can help your team increase output, improving your company’s bottom line.

Accuracy, precision and reliable consistency are essential when manufacturing quality metal parts. Burrs, which include sharp edges and imperfections, affect the functionality, lifespan and aesthetics of metal components. With the right equipment, deburring metal can be relatively simple and effectively remove burrs from manufactured or welded metal parts. This critical step adds the finishing touches needed to smooth irregularities and deliver repeatable parts and products your clients can rely on.
Why Is Deburring Important When Manufacturing Metal Parts?
Sharp edges and irregularities affect overall functionality and compromise the quality of metal components. However, the implications of neglecting deburring during manufacturing run far deeper.
Failing to remove burrs from metal parts affects:
Product safety: Unexpected sharp edges pose risks to workers during production and end-users.
Machinery longevity: Metal burrs cause additional friction and wear and tear on machinery resulting in higher manufacturing equipment maintenance costs and shorter equipment lifecycles.
Cost efficiency: Nonuniform components are often rejected or relegated to scrap, which negatively impacts profit margins.
Consistency and precision: Unintended ridges and protrusions affect the overall uniformity of metal parts and impact specifications and tolerances. Burrs can also affect the accuracy of measurements, which can lead to production errors.
Product performance: Imperfect parts interfere with fit and affect the reliability of metal components.
Legal compliance: Irregular metal parts detected in heavily regulated industries, such as health care, where strict quality control of parts is critical, can result in legal repercussions.
Understanding the 5 Types of Metal Burrs
Not all metal burrs are the same. Depending on the types of metal finishing being used, which can include bending, cutting, piercing or shearing, burrs of various shapes and sizes may occur. These common metal imperfections have been categorized into the following five distinct types:
Poisson burrs: Excess metal at the end of parts that extend sideways
Rollover burrs: Slithers of curled metal projecting from the part
Tear burrs: Swelled shapes in the metal also called breakout burrs
Cut-off burrs: Positive or negative burrs that occur at sites where metal is cut
Thermal burrs: Bits of cooled molten metal that adhere to parts, usually as the result of welding, plasma or laser cutting
The Advantages of Automated Metal Deburring
Although it is possible to deburr metal parts manually, the process is time-consuming and prone to human error. Automating the process provides manufacturers with reliable processes, enhanced speed and accurate results while eliminating potential safety risks to workers.
