How much does the Bystronic BySpeed Pro 4020 cost?
Estimated price range
Our best estimate for a cnc laser cutting machine in this class — not a quote from Bystronic. Configuration moves it a long way.
Overview
The Bystronic BySpeed Pro 4020 is a fiber laser cutting machine with a 4,000 × 2,000 mm working area and linear motors on the X and Y axes. The model is not in Bystronic's current lineup, so the listed figures are mainly of use to someone assessing a machine already in service.
Four power levels are listed: 6 kW, 10 kW, 12 kW and 15 kW. The thickness limits are all quoted for 15 kW: 30 mm in mild steel, 30 mm in stainless steel and 25 mm in aluminium. A machine fitted with one of the three smaller sources will cut less, and the table does not say how much less, so establish which source a particular machine carries before judging it against thick-plate work.
Traverse speed is listed at 170 m/min and cutting speed at up to 50 m/min. The gap between the two shows where the linear motors earn their place: in the moves between contours and on thin sheet, not in plate near the thickness limit. Positioning accuracy is ±0.05 mm. Sheets of up to 1,500 kg can be loaded. A full-format sheet at the thickest listed plate can weigh more than that, so weight needs checking alongside thickness. The control is Bystronic ByVision Cutting and the CAM software is Bystronic BySoft 7.

Strengths & Limitations
Strengths
- 4,000 × 2,000 mm working area takes large-format sheet without repositioning
- Linear motor drives on the X and Y axes with a listed traverse speed of 170 m/min
- At 15 kW the listed limits are 30 mm in mild steel, 30 mm in stainless steel and 25 mm in aluminium
- Listed with a choice of 6 kW, 10 kW, 12 kW or 15 kW fiber sources
- Positioning accuracy listed at ±0.05 mm
Limitations
- Thickness limits are listed for 15 kW only; nothing is given for the 6 kW, 10 kW or 12 kW sources
- Sheet weight is capped at 1,500 kg, which restricts full-format sheets of thick plate
- Cutting speed tops out at 50 m/min against 170 m/min of traverse, so the speed advantage is confined to thin material and positioning moves
- The listed figures give no machine weight, footprint or power consumption for installation planning

Frequently Asked Questions
01
The listed working area is 4,000 × 2,000 mm in X and Y, with a maximum sheet weight of 1,500 kg. A full-format sheet of thick plate can exceed that weight, so check both limits for the heaviest material you plan to load.
02
The listed figures give limits for the 15 kW source only: 30 mm in mild steel, 30 mm in stainless steel and 25 mm in aluminium. The model is also listed with 6 kW, 10 kW and 12 kW sources, for which no thickness is stated.
03
Maximum traverse speed is listed at 170 m/min and maximum cutting speed at 50 m/min, with linear motors on the X and Y axes. Cutting speed falls with material thickness and rises with laser power, so the 50 m/min figure is a ceiling for thin sheet and not a rate for plate.
04
The control is listed as Bystronic ByVision Cutting and the CAM software as Bystronic BySoft 7. When looking at a machine in service, confirm which software version is installed and whether a programming seat comes with it, since the listed figures cover neither.
