DEMO | V303: Chain Cutting

The V303 boosts performance in high‑volume production with its powerful chain cutting capability, designed to link contours intelligently and reduce non‑cutting time across large nests. Chain cutting allows the machine to cut multiple connected parts in a single continuous motion, significantly reducing pierce counts, shortening cycle times, and improving consumable life. For manufacturers handling repetitive shapes, thick plates, or large batches of identical parts, chain cutting delivers a major productivity advantage without sacrificing accuracy.

By eliminating unnecessary torch lifts and minimizing rapid traverses between parts, the V303 keeps the torch engaged longer, maintains stable cutting conditions, and improves overall workflow efficiency.

Continuous cutting for maximum speed and consistency

Chain cutting groups parts together through shared edges or linked contours, enabling the V303 to move smoothly from one part to the next. This continuous cutting action reduces the number of pierces per nest, which is especially valuable in thick‑plate oxyfuel applications where pierce time is significant.

The rigid gantry structure, helical rack and pinion drive, and precision linear guides ensure that the machine maintains straight, consistent motion throughout long sequences of chained cuts. This results in uniform edges, reduced heat distortion, and reliable dimensional accuracy across every part in the chain.

Because the motion between contours is uninterrupted, the torch maintains stable arc behavior and heat flow, supporting consistent quality even during extended production runs.

Automation that streamlines nested production

Chain cutting integrates seamlessly into the V303’s automated workflow. The machine control software automatically identifies opportunities for contour linking based on part geometry, nesting strategy, and material thickness. Operators simply load the nest and activate the feature. The V303 handles the sequencing of linked cuts, transitions between contours, and the required path adjustments automatically.

The dashboard displays upcoming chained cuts, expected runtimes, and required operator input, helping operators manage their time efficiently across the workshop. The scheduling view provides a clear overview of job order and required tools, allowing work preparation teams to optimize nests for chain cutting and reduce plate change frequency.

Combined with Plate Verification, the machine ensures that chained sequences are positioned correctly before cutting begins. When nesting into remnants, chain cutting ensures that every part is produced within the remaining usable area, maximizing material utilization.

Improved cut quality during long chained sequences

Chain cutting benefits directly from the V303’s advanced cutting technologies. With plasma, TrueVolt height control maintains the correct stand‑off distance during long continuous cuts, ensuring smooth edges and extended consumable life. When working with thick plate, the oxyfuel dross inhibitor prevents slag buildup during repeated piercings and transitions, keeping edges clean throughout the entire chain.

The magnetic torch mount ensures fast recovery and minimal downtime should a collision occur during a chained sequence. Since both plasma and oxyfuel torches use the same mount, operators can switch easily between technologies when nests require different cutting processes.

The improved resume function strengthens chain cutting reliability by allowing the V303 to resume cleanly anywhere in the linked sequence. Whether restarting directly on a contour or piercing in scrap, the system ensures the chain remains accurate and the final parts meet quality expectations.

Designed for scalable, continuous plate processing

As production needs grow, chain cutting becomes even more powerful. The modular design of the V303 allows the X‑rail and table length to be extended to accommodate larger nests or longer multi‑part sequences. For high throughput operations, the addition of a second gantry enables two machines to process chained nests simultaneously on the same table, doubling output within the same floor space.

Integration with SigmaNEST Load Manager helps distribute linked cutting jobs across multiple machines while maintaining balanced workloads. This ensures that chain cutting is used effectively throughout the entire production environment.
