NC-C110H vs NC-C128H vs NC-C158H — Choosing the Right Helical Cut-Off Capacity Selecting the right cut-off model comes down to matching production capacity to the line's actual demands, and Hsieh Hsu's N.C. Helical Cut-Off series offers three tiers built for exactly that purpose. The NC-C110H, positioned as the entry configuration, runs at a maximum mechanical speed of 250 m/min with an order change speed of 120 m/min, powered by 2 × 55 kW servo motors — suited to production lines with moderate throughput requirements. The NC-C128H and NC-C158H both step up to a maximum mechanical speed of 350 m/min and an order change speed of 300 m/min, with servo motor ratings of 2 × 64 kW and 2 × 78 kW respectively. This makes the NC-C158H the highest-capacity option in the series, intended for manufacturers running higher-volume or more demanding production schedules. Despite these differences in speed and power, all three models share the same ±1.0 mm cutting accuracy, 500–9999 mm cutting length range, 99-order memory capacity, and dual measuring wheel system. That consistency means manufacturers can select based on throughput and power requirements alone, without trading off cutting precision or control functionality between models. https://www.hsiehhsumachinery.com/n-c-helical-cut-offdouble-drivenc-c158h
