How to reliably remove large burrs from thick inserts


Characteristics of thick plate: the thicker the plate, the less ideal will be the quality after cutting. All types of cutting burrs can be easily removed if the correct deburring equipment is used. At the same time, you are guaranteed high process safety and low production costs.

The widely used laser cutting process reaches its functional limit when the sheet thickness reaches ten millimeters or more. Nowadays, OEMs typically use other processes instead, such as plasma cutting or flame cutting. In plasma cutting, a gas jet with a temperature of up to 30,000°C melts the material in the plasma state until the cut is completed; in oxy-fuel cutting, the material is cut along the kerf by increasing the ignition temperature of the material to at least 1150°C (for unalloyed steel).

The high temperature generated during cutting leaves marks and burrs on the workpiece. The hotter the material, the more pronounced the burrs, burrs 3 mm thick or more are not uncommon. Other factors such as sheet metal thickness, material quality and composition, surface and temperature of workpieces can also lead to burr formation. In addition, the settings of the processing parameters of the equipment are an influencing factor: the greater the deviation from the optimal cutting parameters during the work of personnel, the more burrs will be formed during cutting. During plasma cutting, if the cutting speed is too slow, burr formation will also increase. Summing up, under the influence of various factors, more or less large or small burrs will appear on the surface of the workpiece. Large parts with simple outer contours will produce less burr when cut than small parts with many internal cuts or holes.

Easily remove large burrs

In some cases, some special shaped burrs can be easily removed by allowing the flame cut part to cool before placing it on the floor, on a pallet or in a container. However, this operation does not have any technological safety. Relevant personnel or operators must wear suitable protective clothing to prevent the hazards associated with the above operations. On the other hand, this manual grinding and deburring is time-consuming and hassle-free. The constant load generated by the vibration of the tool during operation can be hazardous to the health of workers.

For such a complex machining task in a relatively harsh industrial environment, it is better to use a deburring machine. The deburring machine can process sheet metal parts that cannot be processed by hand due to the burr being too thick. Experience has shown that the deburring roller is the best tool for removing coarse burrs on thick sheets, and it can safely and reliably remove large burrs on parts cut by plasma or flame. The deburring roller is flexibly attached to the edge of the workpiece and acts on it with gravity to remove the burrs. It can even successfully remove several millimeters of thermal deformation burrs formed on sheet metal during the cutting process. The upper and lower edges are then rounded off with a block of sanding brushes, and secondary burrs can also be removed from the sanding process.

Easy descaling of flame cut parts

In addition to burrs, the flame cutting process also produces dross and oxide layers on the underside of the workpiece. These stubborn molecules can be removed with hammer pins in a deburring machine. The ARKU EdgeBreaker deburring machine effectively removes large burrs and slag: the hammer pin strikes the workpiece from below until the slag isthe child is securely removed. The advantage over manual processing is that there is no need to turn over the heavy billet, and the operator only needs to send the cut billet directly to the slag removal equipment. This not only reduces the workload and potential risks, but also simplifies the entire processing process. With deburring equipment, the speed and reliability of slag removal is much faster than manual operation, and the processing is comprehensive, which ensures the safety of the whole deburring process.
