Manufacturing technology has advanced significantly over the past few decades, and precision tube cutting and deburring services have become a necessity for demanding applications in components within the electronics, semiconductor, and aerospace industries.
Deburring Metal Parts | Precision Tube Cutting Unfortunately, during the cutting and forming process, burrs, tiny nodes, particulate residue, and sharp edges are created on metal surfaces that are not only dangerous to operators, but can also affect the durability of the finished product if not removed. These burrs may not even be noticeable or visible to the naked eye, so they can easily go unnoticed. However, they do exist and must be removed. If not removed, burrs left on metal surfaces can seriously affect the performance of a component over time. They can cause problems during processing, lead to measurement errors, additional friction and wear, and even cause the component to break.
What is Deburring?
Removing burrs from metal surfaces is critical to product performance. In manufacturing, deburring is a cleaning process that uses specialized tools or machinery to remove unwanted material remaining on the metal surface. Deburring is necessary to keep stainless steel components functioning efficiently.
Metals go through a variety of manufacturing processes before they are formed into usable components. Materials need to go through various mechanical processes such as grinding, milling, cutting, drilling or turning. All of these machining operations leave three types of burrs on the metal surface: Poisson burrs, flip burrs and chipping burrs. These unwanted defects must be removed by deburring.
Reasons for Deburring
The necessity of deburring is related to the following factors:
Performance
Functionality
Effectiveness
Safety
Durability of the part
If metal objects are not deburred after forming, they may cause a series of problems in subsequent production. Problems such as improper fasteners and assembly, reduced stress cycles, shortened fatigue life, increased stress that reduces resistance to fracture and cracking, increased risk of corrosion, increased friction and heat, static discharge, poor lubrication and various unsafe operations.
Deburring eliminates the risks that parts face during the manufacturing process. By cleaning and grinding metal edges after forming, you can prevent hazards and accidents, improve product performance, enhance the product’s ability to work properly, and enhance the appearance of attractive appearance.
Deburring Technology
There are a variety of technologies that can ensure that parts receive a high-quality, burr-free surface finish. Deburring methods include:
Manual Deburring
Manual deburring is the most common method. It is flexible, relatively simple, and inexpensive. However, it is time-consuming and should be performed by experienced craftsmen who can make modifications as needed.
Mechanical Deburring
Mechanical deburring effectively removes burrs by grinding off the burr or rolling the burr edge inward. The method is known for its high-quality surface finish and takes only a fraction of the time of manual deburring.
Electrochemical Deburring
Electrochemical machining (ECM) is used to deburr parts for high-volume production of extremely difficult materials, precision machining, and hard-to-reach areas. The process works through a combination of electric current and ethylene glycol solution, which dissolves the burr without affecting the material itself.
Thermal Deburring
Thermal deburring, also known as the Thermal Energy Method (TEM), is a rapid deburring method that requires an explosive gas mixture to generate enough heat to burn off the burr. The process can deburr multiple surfaces and remove hard-to-reach burrs.
After cutting and deburring, formed parts may require secondary processing. Welding, brazing, and assembly are typical processes for finishing products. CNC (computer numerical control) machining is another option. CNC is used in conjunction with pre-programmed computer software to control the movement of factory tools and machinery during the manufacturing process. It is known for its precision, high output, and high efficiency.
