How to reliably remove large burrs from thick plates

Characteristics of thick plate: the thicker the plate, the less ideal the quality after cutting. If you use suitable deburring equipment, you can easily remove all kinds of burrs produced by cutting. At the same time, it ensures high process safety and low product cost for you.

When the thickness of sheet metal reaches 10mm or even thicker, the widely used laser cutting process has reached the functional limit. At this time, OEM enterprises usually use other processes, such as plasma cutting or flame cutting. In the process of plasma cutting, the gas jet with temperature up to 30000 ° C melts the material in plasma state to complete the cutting; Flame cutting is cutting by raising the ignition point of the material to at least 1150 ° C (for non alloy steel) along the cutting seam.

The high temperature generated by cutting will leave traces on the workpiece and form burrs. The higher the material temperature, the more obvious the burr is. Burr with thickness of 3mm or more is not uncommon. Other factors such as sheet metal thickness, material quality and composition, surface and cutting temperature will also lead to burr formation. In addition, the processing parameter setting of the equipment is also an influencing factor: the greater the deviation between personnel operation and the optimal cutting setting, the more burrs will be generated during cutting. In the process of plasma cutting, if the cutting speed is too slow, it will also aggravate the formation of burr. To sum up, under the action of various factors, the surface of the workpiece will produce more or less, large or small burrs. Compared with small parts with many internal cuts or holes, large parts with simple external contour will form fewer burrs during cutting.

Easy removal of large burrs

In some cases, burrs of special shapes can be easily eliminated: let the flame cutting part cool first, and then place it on the ground, on the pallet or in the container. However, this operation does not have any process safety. Relevant personnel or operators need to wear appropriate protective clothing to prevent the hazards caused by the above operations. On the other hand, this manual grinding and deburring is time-consuming and time-consuming. The continuous load caused by the vibration of tools during operation will endanger the health of employees.

For this heavy processing task, deburring machining is a better choice in a relatively harsh industrial environment. Deburring machine can handle sheet metal parts that cannot be processed manually due to too heavy burrs. Practice has proved that the deburring roller is the best tool to remove the coarse burr of thick plate. It can safely and reliably remove the coarse burr on plasma or flame cutting parts. The deburring roller is flexibly attached to the edge of the workpiece and applies gravity to deburr it. It can even successfully remove several millimeters of thermal deformation burrs on the sheet metal during the cutting process. Then, the upper and lower edges are rounded by grinding the brush unit, and the secondary burrs generated in the grinding process can also be removed.
