Plate Deburring Machine - Simultaneously Handling Multiple Types of Edge Defects, Breaking the "Efficiency Bottleneck" in Large-Size Plate Processing

For enterprises producing stainless steel decorative plates and home appliance shell plates (such as refrigerator side plates and washing machine shells), problems such as burrs, flash, and uneven cuts on the edges of plates after processing are extremely common. These defects seem minor but have a huge impact on product quality and production efficiency. If manual tools such as hand-held angle grinders and sandpaper are used for processing, workers need to grind repeatedly to barely eliminate edge defects, which is not only time-consuming and labor-intensive but also prone to uneven edge height differences (errors often reaching 0.5-1mm) due to uneven hand force, thereby affecting the sealing and aesthetics of subsequent plate splicing. Some home appliance shell plates even cannot be accurately assembled with other components due to excessive edge height differences and can only be scrapped. However, most traditional plate deburring equipment adopts a single-station operation mode, which can only process one edge of the plate at a time. For large-size plates with a length of more than 3 meters and a width of more than 1.5 meters, it often takes 15-20 minutes to process one plate, which is far from meeting the efficiency needs of enterprises' mass production. As a result, plates often pile up in the production workshop waiting for processing, seriously restricting the overall production progress.
Our plate deburring machine innovatively adopts the "multi-station linkage + profile grinding" design, fundamentally solving the efficiency and quality problems in large-size plate processing. The equipment is equipped with a heavy-duty conveying workbench that can stably accommodate plates with a length of 6 meters and a width of 2 meters. The surface of the workbench is made of non-slip and wear-resistant material, which can effectively prevent the plates from sliding and shifting during transportation. Three sets of independent grinding units are respectively arranged on both sides and the front end of the workbench. These three sets of units can realize synchronous linkage operation, and simultaneously perform deburring treatment on the two long edges and one short edge of the plate, greatly shortening the processing time of a single 3-meter-long plate to less than 5 minutes, with an efficiency increase of more than 3 times. At the same time, each set of grinding units is equipped with a highly adaptable profile grinding wheel. The shape of the grinding wheel can be flexibly changed according to the type of plate edge cut (such as right-angle cut, arc cut, and bevel cut). During the processing, the profile grinding wheel can automatically fit the contour of the plate edge to adjust the grinding trajectory. Whether it is sharp metal burrs, raised stamping flash, or rough cutting surface, it can be ground flat at one time, ensuring that the edge of the processed plate is smooth and flawless. The gap error during subsequent splicing is strictly controlled within 0.1mm, fully meeting the assembly precision requirements of high-end decorative and home appliance shells.
In addition, the equipment also has a flexible parameter adjustment function. Operators can accurately adjust the grinding speed (which can be freely switched between 800-2500r/min) through the knobs on the equipment control panel according to the thickness of the plate (applicable range 0.5-10mm) and material characteristics (such as high hardness of stainless steel, soft texture of aluminum alloy, and easy scratching of galvanized plate surface). For stainless steel plates, the speed can be appropriately increased to enhance the grinding force and ensure complete burr removal; for aluminum alloy and galvanized plates, the speed is reduced and matched with fine-grained grinding wheels to avoid scratches or excessive grinding on the plate surface caused by too high speed. After a large home appliance shell manufacturer introduced this equipment, the daily processing capacity of plates quickly increased from 30 to 120. The deburring process that originally required 8 workers can now be completed by only 3 workers operating the equipment, directly reducing labor costs by 50%. At the same time, due to the improved precision of the plate edges, the rework rate of the subsequent splicing process has dropped significantly from 12% to 1.5%, saving the enterprise more than one million yuan in rework materials and labor costs every year.
