SG‑900 Automatic Grooving Machine is high‑speed V‑grooving equipment for cardboard processing. It adopts belt‑rubbing automatic feeding and side‑transport design to eliminate instability caused by manual feeding. The belt‑pressing structure holds cardboard firmly against rollers to guarantee consistent grooving precision and speed. It completes auto‑feeding, correction, V‑groove cutting, chip removal and finished‑board collecting in one automatic workflow. Producing clean, burr‑free V‑grooves for sharp‑corner folding of rigid boxes and book covers.
