Deburring is the process by which edges or ridges of machined parts and other objects are neatened or smoothed. All sorts of materials, including metal, wood and plastic, need this this treatment; it’s a common stage in industrial manufacturing, as well as in electronics, building construction, automotive, aviation and medical device production. Generally, deburring machinery is required after processes like molding, forging, stamping, drilling or machining. There are various types of automatic and manual deburring machinery on the market, as well as deburring media, which are abrasive materials that help deburr a surface without harming the a non-targeted area.
The two main categories into which automated deburring machinery fall are rotational tumblers and vibratory tumblers. Tumblers are barrels within which parts and materials are deburred, polished or otherwise cleaned from friction created between deburring media and some kind of movement. In the case of rotational deburring, barrels are spun or rotated in such a way as to mimic natural erosion, while in vibratory deburring, vibrations polish and grind away burrs. Vibratory deburring is also called vibratory finishing and mass finishing. Similar to these is the parts tumbler, which is usually much larger and is specifically designed to deburr mechanical parts only. Other automatic deburring machinery includes flat surface finishers, polishing lathes and abrasive belts. A vibratory finisher, for example, provides similar polishing and imperfection removal as vibratory tumblers, but unlike tumblers. However, vibratory tumblers, which often feature vibrating sections and conveyor systems, are far more complex than their tumbler cousins In addition to automatic deburring, manufacturers may also choose to employ manual deburring techniques. Manual deburring involves the application of abrasive compounds to a surface via rubber wheels or nylon filament cloth and brushes. Read More…
In addition to these, a relatively new technique is also making headway in the manufacturing world. This technique, called electrochemical deburring (ECD), utilizes controllable electrical energy to deburr selected areas, rather than entire parts, then wash away the deburred material using pressured electrolytes. This allows technicians to deburr only the areas that need deburring, rather than an entire part or material. Also, with ECD, the tool and workpiece do not have to come in contact, which means that the workpiece is not subject to any thermal or mechanical stress. ECD deburring, which must be done on clean, conductive surfaces, allows the deburring of materials that cannot be scratched or altered otherwise. Also, some deburring machinery uses robotic technology to achieve precision deburring and polishing. Large parts may require a large, robotic deburring machine like this, such as, for example a cabinet or desktop polisher.
The aforementioned deburring media may be wet media or dry media. Common media materials include silica ceramic, synthetic plastics and natural materials like corn cob and walnut shells. The most frequently used of these is ceramic media, which is quite abrasive and is good for use on hard metals like stainless steel. Ceramic media are available in pre-formed shapes like triangles, cylinders, cones, ellipses and wedges. Synthetic plastic media, such as polycarbonate, acrylics and polyester, is less abrasive than ceramic and thus used on softer materials such as aluminum. Plastic media, also called plastic grits, is additionally available as wet media, perfect for tumbling. Finally, corn cob media is a clean, effective and environmentally-friendly alternative that is great for fine finishes and absorbing hard to remove liquids and particles like dirt, grease and oils, from soft metals.
Deburring machinery is a valuable investment for nearly any manufacturer. Equipment that deburring machinery serve includes, but is not limited to: molds, dies, chemical components, pharmaceutical components and both large and small industrial parts and machinery. Because so many processes can leave behind sharp edges, bumps, raised edges, burrs or seams that interfere with an overall task, most products cannot be used or sent to retail before deburring. A failure to deburr could lead to operational damage, ineffectiveness and accidents or injury, as well as poor aesthetics and quality. In addition, the smooth surface achieved by deburring prevents areas of stress and weakness from going unnoticed and allows for accurate mathematical and/or scientific performance analysis. To acquire the most effective deburring machinery for your application, speak to a professional or a deburring machinery manufacturer. They can guide you to the right equipment, whether it be a large industrial machine or handheld tool.
The Importance of Deburring Machinery in Industrial Processes
In the simplest definition, deburring machinery helps businesses to carry out the deburring process. Deburring is a method of giving a finishing touch to the material. The engineers, using specifically-purposed machines, remove the unwanted parts from the surface of the materials. Industrial procedures such as welding, molding, cutting, slitting, and casting.often render an uneven surface, which is modified and smoothened using suitable deburring machinery.
A rugged, bumpy, rough surface can declassify the look of the machine and also make the manufacturing business look bad. Furthermore, an irregular surface and edges increase the risk of improper machinery performance and accidents. Uneven bits on the surface and edges of the materials are referred to as burrs. The job of deburring machines is to remove the burrs from the surface of the material. Before the invention of these machines, burrs were removed manually. However, there are still many processes and materials for which we cannot use these machines.
Various deburring machines are used by industries to add a fine finish to different materials. Different machines work with different methods and in different environments. Which type of deburring machinery will be used by engineers majorly depends on which material they are working on.
Some deburring machines can also apply a coating on the material surface to create a smoother and shinier finish. Sometimes, tiny and soft bits are distanced by rubbing two surfaces of the same material together.
At times, sanding is also performed by the deburring machine to remove all the unwanted bits and pieces from the material. Besides sanding, additional deburring processes such as painting or coating can sometimes be used to achieve the desired finishing.
Importance of Deburring
If you are expecting quality in your production, then you will need to ensure that your products are not only strong, but also have a superior finish. In addition, materials with superior finish are also an important factor that determines the final quality of the goods produced by a business.
The following descriptions underline a few points that explain the importance of using deburring machinery.
Smooth functionality – By removing the burrs from the material surface, you can ensure that your machines and processes run smoothly. Smooth functioning means that your processes are meeting your production demands.
Cost savings –Uneven and irregular quality material can hamper the production cycle, which will add to the cost of production. Additionally, the poor quality of the material will lead to poor quality products, which will be denied by consumers. Deburring machines help you remove burrs from the material surface and increase the quality of the material. This way, nothing will bar your production process, and you will save plenty while gaining better margins on your sales.
Put an end to wearing and corrosion – A number of deburring machineries apply a coating on the surface of the material. This coating acts as a protective layer that increases the resistance of the material against wearing, tearing and corrosion.
Terms Associated with Deburring Machinery
Deburring is an important industrial procedure in which engineers make use of modern-day machines to remove debris and burrs from the materials and machine parts. There are numerous deburring machines used for various materials and parts washing purposes.
Parts washers are also a kind of deburring machinery that help eliminate unwanted burrs from the material. However, an advanced deburring machine is not just limited to cleaning the parts. Some deburring machines also perform the job of a polishing machine. These utilities are taken in routine to fill up the flaws and spots on the materials or parts. A deburring polishing machine helps engineers ensure that their machine parts and materials are ready for smooth functioning.
Deburring machines have a crucial role to play. However, for businesses that are new to this machine, or are looking to buy deburring machinery for the first time, the following points describe a few frequently used terms associated with deburring machines.
Understand different types of burrs: If you are familiar with metal fabrication, specifically, steel sheets and plates, then you would encounter two types of burrs. The two types of burrs that metal sheets or plates catch are: mechanical burrs and thermal burrs. Mechanical burrs are a result of mechanical processes, such as drilling, cutting, shearing, sawing, etc. On the other hands, a metal sheet gets thermal burrs when it is cut using a powerful source of heat – such as a laser. Laser cutting, which typically is considered a method of cutting metals easily and finely–causes thermal burrs on the steel sheet.
There are many other types of burrs, for example – scallops, nibbles, and marks – that occur during the machine operation.
Parts of deburring machines: These machines are an amalgamation of robust mechanisms such as a brush and belt, the two most significant parts of a deburring machine. Many suppliers give you options to customize your deburring machine as per your application needs. Nowadays, you can also source multimedia deburring machinery as well. These machines are engineered to perform multiple jobs, helping the business to save money on their investments in numerous machines. Some machines of today have three to four heads that can complete the burr removal process in less time.
Contact Drum: A contact drum is a drum of rubber material that has an abrasive belt around it. In many designs, it is designed as an ideal drum that rotates along with the belt and brush of the machine. The material from which the contact drum is made is soft, smooth and flexible. Because of this, the contact drum ensures smooth and efficient cleaning.
Wet Deburring Machine: Wet deburring machines strategically use a coolant through a filter that catches and removes dirt and particles from the parts. Some machines have their own filtering system, while others will require you to get one separately.
Dry Deburring Machine: Dry machines are low on maintenance and have a long life. However, they will most likely leave particles on the surface of the machine. This way, this piece of machine must be used carefully under the supervision of experts.
