Laser cutting
The workpiece is heated by a high-energy-density laser beam so that the temperature rises rapidly and reaches the boiling point of the material in a very short time. The material begins to vaporize and forms steam. The ejection speed of these steam is very high, and at the same time, a cut is formed on the material.
What are the burrs?
It is one of the common phenomena produced in the processing of fiber laser cutting machines. Various sharp corners, burrs and other irregular parts that sometimes appear at the transition of the workpiece surface during laser cutting are burrs.
Many companies find that the cut workpieces have a lot of burrs and the quality is very unsatisfactory when using laser cutting machines for cutting, so they suspect that there is a problem with the quality of this cutting machine. Is this really the reason? In fact, it is not necessarily. In most cases, the generation of burrs is not due to the quality problems of the laser cutting machine itself, but due to the operator's incorrect operation method or the inadequate maintenance and maintenance of the cutting machine. In addition, there is another main reason for the generation of burrs, that is, the auxiliary gas problem. When laser cutting is performed, the laser beam irradiates the surface of the workpiece to generate extremely high temperatures, causing the surface of the workpiece to vaporize and evaporate rapidly, thereby achieving the purpose of cutting metal. The function of the auxiliary gas is to blow away the slag remaining on the surface of the workpiece after the workpiece is vaporized by the laser beam. If this is not done, a layer of attached burrs will form on the cut surface of the workpiece when the slag cools.
Below, let's summarize the methods of dealing with burrs to help you solve the problem of laser cutting burrs
5 common methods for deburring laser cut parts
1) Manual deburring
This is also a common method used by general companies, using files, sandpaper, angle grinders, polishing wheels, etc. as auxiliary tools. The labor cost is expensive, the efficiency is not very high, and it is difficult to remove complex cross holes. The technical requirements for workers are not very high, and it is suitable for products with small burrs and simple product structures.
2) Die deburring
The die is made and the punch press is used for deburring. A certain die (rough die + fine die) production fee is required, and a shaping die may also be required. It is suitable for products with simple parting surfaces, and the efficiency and deburring effect are better than manual.
3) Laser Deburring
Laser deburring is an emerging deburring method that uses a high-energy laser beam to instantly heat the metal surface, melt it, and evaporate the burrs. This method is characterized by high precision, non-destructiveness, and high efficiency, and is suitable for various metal materials and workpieces with complex shapes. However, laser deburring equipment is expensive, requires professional technicians to operate, and has limited removal effects on deeper and smaller areas.
4) Barrel Deburring Machine
This is mainly suitable for smaller parts. After the sheet metal to be processed is placed in a drum with abrasives and mixed and rolled for a certain period of time, the burrs can be removed and the originally sharp edges will be blunted. However, the disadvantage is that it is not suitable for large parts, and some workpieces cannot be rounded.
5) Automatic Deburring Machine
ADV Grinding specializes in the field of deburring. Modern deburring machines can quickly adapt to changes in processing tasks by enabling or disabling processing units, or quickly shutting down abrasives. We have developed a special equipment for deburring flat sheet metal. The universal rotating brush rotates alternately at high speed, and the abrasive scrapes the corner of the workpiece to remove the burrs evenly and achieves a high-end precision processing effect. It mainly cuts the edge rounding part, with little friction on the plane. It has automatic transmission and high efficiency, and is suitable for batch processing.
