When metal goes through machining operations like grinding, milling, or drilling, it can leave surface imperfections called burrs. Unless they’re cleared away, they can cause problems like decreased fracture resistance, shorter fatigue life, and improper fastener seeing. Deburring is the process of cleaning up these small ridges and protrusions so that the final product functions as intended. While there are a variety of deburring tools available to deliver premium-quality, burr-free finishes, the three types mentioned in this article are the most popular for their ease of use and excellent results.
Manual Deburring Tools
According to Engineering 360, manual deburring tools are the most commonly used option. These hand-held devices consist of a tool and deburring blade. Depending on which brand you buy, you may be able to change the blades when they wear down or switch applications. They also have rotating blades that work constantly while deburring and a telescopic handle to support applications with a longer reach.
Advantage & Disadvantages
The biggest advantage to using manual deburring tools is that they’re cost-effective, flexible and easy to customize. You can check your work as you go along and improve as necessary. The biggest downside is that manual deburring takes longer, so it’s less suitable for high-volume work.
Mechanical Deburring Tools
With mechanical deburring tools, you grind off the burr or roll the edges onto itself and flatten it so it doesn’t protrude. Unlike manual deburring, which involves a hand tool, you use a specially designed machine to get the job done.
Advantages & Disadvantages
The advantage of this method is that it offers high-quality finishes in a fraction of the time it takes to deburr manually. This is why mechanical deburring tools are a fixture in most machining operations. Eliminating the need for hand sanding and grinding increases productivity and improves the finished results. On the other hand, mechanical deburring equipment takes up more space, and definitely more costly compared to manual deburring.
Electrochemical Deburring Tools
Many fabricators use electrochemical machining (ECM) for deburring when doing precision work or dealing with difficult materials and hard-to-reach spots. Electrochemical energy is conducted through the burrs using a salt or glycol solution, eliminating them without destroying the surrounding metal. The deburring equipment is a cathode that uses a DC current and the above-mentioned electrolyte fluid to create an anodic reaction that removes burrs quickly and precisely.
Advantages & Disadvantages
Electrochemical deburring yields an excellent surface finish and highly accurate results. The workpieces experience no thermal stresses and the process itself is efficient, which increases plant productivity. The main disadvantages are the skill required and the high initial cost of the equipment. However, the benefits outweigh these concerns.

Sandblasting is an industrial process that is also referred to as abrasive blasting. The sandblasting process dates back to 1870 when Benjamin Chew Tilghman first took out a patent for this newly invented industrial finishing process. Tilghman had taken note of the effect on windows caused by wind-blown sand in the desert. This eventually gave him the idea to refine the process of sandblasting for various industrial applications. In 1877, Tilghman took out a second patent for sharpening industrial files uniquely marketed as “liquid grindstone”. Initially, he has found the process particularly well-suited for sharpening files, cleaning metal surfaces such as boilers, and finishing wooden grain surfaces. Since that time, the sandblasting service has been used worldwide for various industrial applications.
How Are Sandblasting Services Performed?
Sandblasting is performed by forcibly expelling a high-pressure stream of abrasive material called a media against a solid surface. The person conducting the sandblasting service must wear a variety of personal protective equipment (PPE) to protect their eyes, hands, and skin from these high-velocity particles. Typically, compressed air is used in the sandblasting process.
However, some sandblasting machines use a centrifugal wheel to project the media at the target surface. The equipment used for sandblasting includes a machine chamber where the media and compressed air are mixed. The air and particle mixture are then forced into a hose and out through a hand-held nozzle to direct the spray of particles at the work surface. Sandblasting equipment is made from tough and durable materials, such as boron carbide since it must resist the abrasive wear and tear of the process.
Variations of the sandblasting process may use different media, some of which are highly abrasive while others are less abrasive. For instance, sand or metal shots are used as the most abrasive media types, while less abrasive variants of the process might use glass beads, plastic stock (PMB), corncobs, or even walnut shells. Lastly, some blasting processes are barely abrasive, including soda blasting which uses baking soda and dry-ice blasting.
What Are The Benefits Of Sandblasting?
Like many other industrial processes, sandblasting can be used for various industrial applications. Sandblasting is often used to polish and smooth a rough surface, for starters. But you can also use it to rough up a smooth surface, which is usually done to prepare the surface for painting. Alternatively, sandblasting can be used to re-shape a surface, or you can use it to clean and remove particle contaminants from a surface.

Press brakes are advanced fabrication machines that play a vital role in the custom metal fabrication industry. The press brake is essentially used to bend and shape metal into the desired two-dimensional or three-dimensional shape by applying external force. Without the press brake, shaping metal would be nearly impossible. It is the most common method used for industrial metal bending. Press brake forming is used to create metal fabrication pieces for various industries, including aircraft, automotive, construction, housing, and more. However, there are many different types of press brakes and today, we’ll discuss what those are.
Pneumatic Press Brake
A pneumatic press brake essentially bends metal with compressed air or gas. An electric charge kick starts the machine into motion which then feeds compressed air or gas into tubes that are attached to the press mechanism. The tonnage used on the metal piece depends on the air pressure used in the pneumatic press.
One of the safest press brakes
Hydraulic pressers are named after their hydraulic cylinders and work under the principle of Pascal’s Law. It utilizes two hydraulic cylinders that perform in a synchronized manner and rely on gear pumps to push oil side to side. This allows more control and consistent strokes when you are working on metal. It’s extremely powerful and reliable but isn’t as energy-efficient and can be expensive to maintain.
Low initial cost
Easy to use
Mechanical Press Brake
Mechanical press brakes are the oldest type on the market. Typically, an electric motor provides energy to a flywheel. The operator controls the clutch which manipulates the flywheel putting the crank mechanism into action providing the necessary force to bend metal. It’s much more straightforward to use making maintenance and operations easier.
Low maintenance cost
Servo Electric Pressers
Judging from the name, you can assume that this type of press brake uses a servo-electric motor that powers a belt drive to exert pressure on pieces of metal. It’s also been referred to as an electric hydraulic press brake. Although it’s super-fast and efficient, it is limited to work that uses low tonnage. It also provides the highest accuracy compared to most press brakes.
Significant energy saving
Low maintenance cost
High production efficiency
High bending accuracy

Stainless steel finishes play a vital role in any design specifications. Not only is it for practicality but it’s used for enhancing the appearance of the final product as well. There are a variety of options when it comes to steel finishes. With some exceptions, most finishes are usually classified by number. Every finish is used to achieve different visual effects that are specific to the industry and the final product. For example, a mirror finish is more commonly used for ornamental trim or columns seen in luxury hotels whereas a brushed finish is used commonly in automotive design. The textures, grain orientation, patterns, and other features should be discussed thoroughly with your fabricator. This guide will help you distinguish between some of the most commonly used stainless steel finishes.
No. 2B – Matte Finish
Judging from the name, you can assume the results. A matte finish will appear dull and non-reflective similar to a cloudy mirror, which makes it a good choice when aesthetics isn’t a priority. No. 2B is usually the least expensive compared to the other options and it also happens to be one of the most popular finishes. It’s most commonly used for equipment in a variety of industries including pharmaceutical, chemical, laundry, and even household appliances like parts for refrigerators and kitchen tools.
No. 3 – Brush Finish
Produced through extended brushing, this process creates a moderately reflective finish with one-directional and somewhat coarse polishing lines that extends along the length of the product. It can be achieved using either mechanical or gradual finer polishing techniques. Depending on the product and the application requirements, the grit can determine how reflective the finish is. The higher the grit number the finer the polishing lines are. This type of finish is usually reserved for manufacturing, and food processing equipment such as brewing equipment, and kitchen equipment.
No. 7 – Polished Finish
This type of finish is known for its reflective, very bright, mirror-like appearance. It’s achieved through polishing a No. 4 finish with a 320 grit and up to 10 minutes of extended buffing which produces a higher degree of reflectivity. It has minimal grit lines that can still be seen when you’re standing a few feet away. A common finish that prepares your stainless steel for chrome plating, powder coating, and more. The polished finish is used for architectural designs such as column covers, ornament trim, and wall panels.
No. 8 – Mirror Finish
Similar to No. 7, the mirror finish appearance is highly reflective. No. 8 is actually the most reflective compared to all the other options. The mirror finish can be accomplished through extended buffing (5-10 more minutes than No.7). The extensive buffing essentially gets rid of the grit lines but they’re still visible up close, hence why it’s not the perfect mirror. This stainless-steel finish is typically used for interior architectural designs such as panels, columns, and ornamental applications seen in museums, luxurious office buildings, and more.

It has been around for more than 150 years and is used for a wide range of applications. This includes construction, residential use, rail, road, agriculture, etc. Galvanized steel is steel that has been coated in a protective layer of zinc. There are many benefits to using this material that we will discuss further. The fact is that it’s a tough and versatile metal. Most importantly, it’s corrosion-resistant. To learn more about galvanized steel, keep reading.
Galvanized Steel – What Is It?
We know that steel itself is a strong durable metal, but galvanized steel can be even better. The zinc galvanized steel is coated in prevents corrosion. Normal steel, despite being strong and tough is susceptible to rust and corrosion. This can be caused by rain or constant contact with other liquids as well as humidity in the air. Corrosion is the main enemy of steel, and the process of galvanizing prevents the onset of this issue.
Why Is Zinc Used?
While other metals can also help in this regard, zinc is affordable, easy to apply, and extremely effective. The addition of zinc, in the process of galvanization, improves the steel and minimizes the risk of corrosion. The process was established in England and France as far back as 1837. At that time, the steel was dipped into molten zinc and the process was known as hot-dip galvanization, a process still used to this day.
The Process of Galvanizing Steel
There are various ways to galvanize steel. When molten zinc is added to steel, a chemical reaction causes it to adhere to the steel providing the protective coat. Hot dipping is the most common way to do this but there are other methods. These include zinc, electroplating, mechanical plating, and sherardizing. Zinc metal spray and continuous strip galvanizing are additional methods. The ideal method will depend on the application and the applicator, hence why it’s important to work with companies you can rely on.
The Benefits of Galvanized Steel
The main benefits of galvanized steel are that it is tough, durable, and corrosion-resistant. This makes it a relatively sustainable material to use in structures. Despite the higher initial costs, the strength and durability make it an economical choice over time. Little to no maintenance will be needed for many decades. The galvanizing process is effective and delivers complete coverage. The bond that is formed when zinc is added is extremely strong and reliable. It has proved itself over time, making it predictable. You can measure the lifespan according to the coating thickness with a high rate of accuracy. It also helps during transport, handling, and storage. It makes the project easier to complete and ensures the integrity of the result with minimal hassle and fuss.
What Industries Use Galvanized Steel?
It is used extensively in various industries wherever strong corrosion-resistant metal is needed. This includes:
