Overview
The Bystronic BySpeed Pro 4020 is Bystronic's high-speed, large-format fiber laser cutting system, purpose-built for fabricators who need to maximize throughput on large sheets in high-volume production environments. With a 4,000 × 2,000 mm working area and fiber laser power up to 15 kW or higher, the BySpeed Pro 4020 targets steel service centers, heavy fabricators, and high-volume contract manufacturers who cannot afford cycle time losses on large structural or decorative panels.
The machine's dynamic linear drive system is engineered for extremely high acceleration and traverse speeds, enabling fast repositioning between cuts that directly translates to more parts per shift on thin-to-medium gauge material. Bystronic's ByCut fiber intelligent cutting process manages cutting parameters in real time, automatically adjusting speed, power, and focus position as the cut geometry changes — maintaining optimal edge quality at maximum achievable speed without operator intervention.
At the 4020 format, the BySpeed Pro handles 4 × 2 m sheets in a single setup, eliminating the need to reposition or stage large blanks. This is particularly valuable for structural components, large enclosure panels, and architectural metalwork where full-sheet utilization and cut-to-cut time are critical to profitability. Bystronic's ByTower automation and ByLoader integration options extend the machine's unattended production capability across multi-shift operations.
The BySpeed Pro 4020 competes with TRUMPF's TruLaser 5040 and 5060 series and Amada's large-format ENSIS systems. Bystronic's Swiss engineering heritage, strong global service network, and the BySpeed Pro's proven track record in demanding production environments make it a leading choice for high-volume steel and aluminum cutting operations at the 4020 sheet format.

Strengths & Limitations
Strengths
- Large 4,000 × 2,000 mm working area handles full-size structural sheets without repositioning, maximizing material utilization
- High traverse speed up to 170 m/min with linear motor drives minimizes non-cutting time and increases parts per shift
- 15 kW fiber laser cuts mild and stainless steel to 30 mm, covering the full thickness range of most heavy fabrication applications
- ByCut intelligent process control maintains optimal cut quality at maximum speed without manual parameter adjustment
- Proven platform with Bystronic's global service infrastructure and ByTower automation integration for multi-shift unattended operation
Limitations
- High capital cost of $600,000–$1.1M requires high machine utilization and volume to justify investment
- Large footprint of a 4020-format machine demands significant floor space and facility infrastructure planning
- More complex to program and operate efficiently than smaller 3015-format machines — requires experienced laser operators and programmers

Frequently Asked Questions
01
The BySpeed Pro 4020 is available with fiber laser sources up to 15 kW, enabling cutting of mild steel and stainless steel up to 30 mm and aluminum up to 25 mm. Higher power options may be available depending on regional configuration — contact Bystronic for the latest available power levels.
02
The BySpeed Pro 4020 is a higher-tier, larger-format machine designed for maximum throughput in high-volume production. It offers a larger working area (4020 vs. 3015), faster traverse speeds driven by linear motors, and higher maximum laser power. The BySmart Fiber 3015 is a mid-range machine better suited to lower-volume mixed work on standard sheet sizes.
03
Yes. The BySpeed Pro 4020 is designed for full automation integration with Bystronic's ByLoader sheet feeding system and ByTower storage towers. BySoft 7 manages production scheduling across the automation cell, enabling extended unattended operation across multiple shifts.
04
ByCut fiber is Bystronic's intelligent cutting process that automatically selects and adjusts cutting parameters — laser power, speed, focus position, and assist gas — in real time based on material type, thickness, and cut geometry. It eliminates the need for manual parameter optimization and maintains consistent cut quality at maximum achievable speed.
05
Yes. The BySpeed Pro 4020 cuts aluminum up to 25 mm at 15 kW, as well as copper and brass in thinner gauges. The fiber laser source is highly efficient on reflective metals that would damage CO2 laser optics. Nitrogen assist gas is recommended for clean, oxide-free cuts on aluminum and stainless.
