Crawler Type High-Speed Shot Blasting Deburring Machine (Automatic Flash Removal Equipment)

This crawler type high-speed deburring machine is a highly efficient automated equipment specifically designed for removing burrs (flashes) from thermosetting plastic products such as bakelite frames, BMC, LCP, PPS, and small metal castings. Unlike traditional sandblasting machines that use compressed air to propel abrasives, this machine operates on the high-speed rotating impeller projection principle: projection materials are flung at high speed by a rapidly rotating impeller (thrower motor speed up to 2880r/min), creating a high-velocity stream of abrasive particles that randomly impact the continuously tumbling workpieces inside the rubber-lined crawler belt chamber. Workpieces are loaded into the cleaning chamber consisting of a rubber crawler belt; as the crawler rotates forward, it continuously tumbles and stirs the workpieces while the high-speed projected abrasives impact them from all directions, effectively removing sheet-like burrs and burrs in recesses or holes within a short time. The projection force can be adjusted via a frequency inverter on the control panel to suit different workpiece materials and burr conditions. This working principle means the crawler type high-speed deburring machine requires no compressed air to operate, significantly reducing energy consumption and operating costs.

In terms of manufacturing quality and structural integrity, this crawler type high-speed deburring machine features a main frame welded from 3mm~8mm high-quality cold-rolled steel plates, offering robust and durable construction. The equipment integrates a self-feeding projection device, machine cabinet, crawler (tumble belt) conveyor, dust collector, vibrating screen, and static elimination device into a single compact unit. The entire cleaning chamber is lined with wear-resistant rubber to protect workpieces from damage during tumbling. An ingenious abrasive circulation system continuously recycles projected abrasives; powdery burrs and fine particles are captured by the dust collector, while larger burr fragments are filtered out by the screen. A humidifying nozzle is installed in the suction pipe—the appropriate amount of moisture enhances the blasting effect, prevents dust adhesion, and extends the service life of the projection media. The machine integrates the deburrer and dust collector into one unit, saving floor space and reducing dust pollution. High-end models are equipped with a fully computerized control system and LCD touch screen, allowing adjustment of various parameters and one-touch fully automatic operation.

The performance advantages of this crawler type high-speed deburring machine are exceptional. First, extremely high efficiency – each machine can replace 10~15 workers, making it the ideal choice for cost reduction and labour savings. Second, uniform processing quality – the crawler continuously tumbles workpieces while high-speed projected abrasives randomly impact them, ensuring burrs on all surfaces (including recesses and holes) are uniformly removed. Third, high automation – features timed automatic operation; after setting the processing time, the machine runs automatically and stops upon completion without requiring operator attendance. Fourth, no workpiece surface damage – precise control of projection force and processing time removes only burrs without damaging the workpiece surface. Fifth, low maintenance cost – the machine can operate continuously for extended periods without frequent part replacement, with minimal maintenance expenses. Sixth, environmentally friendly and dust-free – equipped with a built-in dust collection system with zero dust emission, fully compliant with environmental requirements.

In terms of application scope, this crawler type high-speed deburring machine is widely used for: Bakelite (frame) products – thermocompression or injection-moulded bakelite frames, transformer bobbins, etc.; Thermosetting plastic products – ABS, DAP, LCP, PPS, PET, PA9T, PA6T, BMC and other glass-fiber-containing brittle plastics; Alloy die-cast parts – zinc alloy and aluminium alloy die-castings; Small hardware parts – gears, saw blades, shaft-type workpieces; Metal castings – surface rust removal for ferrous parts, burr rounding of stampings, surface treatment for forgings and heat-treated components. With its comprehensive advantages of high efficiency, uniform processing, automation, and non-damaging operation, this crawler type high-speed deburring machine has become the preferred choice for burr removal on bakelite products, plastic parts, and small metal components.
