SUMEC TOUCH WORLD

This production line primarily consists of two sets of robotic automatic longitudinal seam welding systems, one automatic grinding system, a complete RGV automated conveying system, and an integrated line control system.
The robotic longitudinal seam welding system includes a welding robot, a welding machine system, a positioner, a laser line automatic positioning, scanning, and tracking system, as well as a welding fume extraction device.
The automatic grinding system comprises a grinding robot, a laser automatic height positioning and recognition system, a force control sensor, a grinding head, an abrasive collection system, a soundproof grinding enclosure, and related accessories. It is designed for both grinding workpiece reinforcement and correcting roundness after sizing (two workstations).
The line features two loading stations, one buffer station (for intermediate storage between welding and grinding processes), and two unloading stations (one of which can also serve as a secondary grinding loading station). Each station utilizes RGV automated workpiece transport and positioner automatic positioning to locate welding and grinding positions, with no manual intervention required throughout the process.

After-Sales Service Terms:
The machine comes with a 1-year warranty (excluding wear-and-tear parts), and lifetime technical support is provided. During the warranty period, the buyer must perform regular inspections and maintenance as outlined in the user manual or the seller's self-check requirements. If any issues arise (excluding wear-and-tear parts or programming-related problems), the seller will respond within 2 hours. However, the warranty does not cover problems caused by tooling or workpieces. If on-site debugging or after-sales assistance is required, the seller may charge a fee, and the buyer shall cover all travel and accommodation expenses.
