Workpieces welded from aluminum plates and steel plates commonly have prominent defects such as weld beads, welding slag, flash and burrs on weld seams. Typical applications include new energy battery housings and precision sheet metal components that require strict dimensional accuracy and ultra-smooth surface finish. High-quality weld grinding is critical to ensuring reliable sealing performance, precise assembly and strong coating adhesion. However, welded workpieces usually produce minor deformation after thermal processing, bringing great challenges to traditional weld finishing procedures.
Conventional weld treatment relies entirely on manual handheld grinding tools. Finishing quality heavily depends on worker proficiency, often resulting in substrate damage caused by over-grinding, incomplete burr removal and poor product consistency. High rework and scrap rates severely restrict production efficiency. Meanwhile, metal dust generated during manual polishing endangers operator health, making traditional processes unable to meet the high-standard mass production requirements of the new energy and sheet metal manufacturing industries.
To solve universal finishing pain points of welded components, Truman has independently developed the intelligent automatic weld seam grinding workstation. As professional Truman grinding equipment, it achieves full-automatic removal of weld seams, burrs, flashes and excess welding allowance, smoothing workpiece surfaces to fully meet subsequent assembly and spraying process standards.
Centered on an industrial grinding robot and equipped with a high-precision servo positioning platform, the grinding workstation performs stable and accurate automatic finishing. After precise workpiece clamping and positioning, the robot carries professional abrasive tools to complete grinding along preset trajectories. The built-in force control system compensates for positional deviations caused by welding deformation and dynamically adjusts grinding pressure in real time. It effectively avoids over-grinding and under-grinding defects and ensures uniform finishing on weld seams and sharp edges.
The customized abrasive materials are compatible with multiple materials including aluminum and steel. The highly adaptable tooling system supports rapid switching and simple commissioning for workpieces of various specifications, greatly improving production flexibility. Realizing unmanned automatic operation, the equipment reduces manual exposure to dusty working environments.
This intelligent welding finishing solution effectively improves production efficiency and product yield while reducing workpiece scrap loss. It provides stable, standardized and high-precision weld scar grinding and surface treatment for new energy battery housings and various sheet metal welded parts.
