How much does the Bystronic ByJet Flex cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from Bystronic. Configuration moves it a long way.
Overview
The Bystronic ByJet Flex is an abrasive waterjet cutting system listed in three table sizes, 3015 / 3020 / 4020, with an intensifier pump at a maximum pressure of 60,000 PSI (4,137 bar). The model is absent from Bystronic's current lineup and the listed figures are unconfirmed, so use them as a starting point when assessing a used system.
Only one size has a cutting area in the table: the 3020, at 3,000 x 2,000 mm (9.8 x 6.6 ft). Z-axis travel is 200 mm (7.9 in), which has to cover the material, the fixturing under it and the clearance above.
The pump is the row to pin down first. Pump power is 37 kW / 55 kW (50 / 75 HP), two different ratings, and the table allows up to 3 cutting heads running simultaneously. Several heads share one pump's output, so which pump a system carries decides how many heads it can feed usefully.
Motion is by linear guides with ball screw drives. Positioning accuracy is ±0.05 mm (±0.002 in), repeatability is ±0.03 mm (±0.0012 in) and maximum traverse speed is 20,000 mm/min (787 ipm). Traverse speed is the rate between cuts, not a cutting rate. Software is BySoft 7, the abrasive is garnet with 80 mesh as standard, and the weight is approx. 6,500 kg (14,330 lbs).

Strengths & Limitations
Strengths
- Three table sizes, 3015 / 3020 / 4020, with the 3020 cutting 3,000 x 2,000 mm (9.8 x 6.6 ft)
- Up to 3 cutting heads running simultaneously for repeated parts
- Intensifier pump at up to 60,000 PSI (4,137 bar), in 37 kW / 55 kW (50 / 75 HP) ratings
- Positioning accuracy of ±0.05 mm (±0.002 in) and repeatability of ±0.03 mm (±0.0012 in)
Limitations
- Not in Bystronic's current lineup; the listed figures need checking on the individual system
- Z-axis travel is 200 mm (7.9 in), which caps the height of material plus fixturing
- Two pump ratings are listed, and the 37 kW (50 HP) pump has less output to share between heads
- A cutting area is listed only for the 3020 table

Frequently Asked Questions
01
The listed table sizes are 3015 / 3020 / 4020. A cutting area is given only for the 3020: 3,000 x 2,000 mm (9.8 x 6.6 ft). Z-axis travel is 200 mm (7.9 in).
02
An intensifier pump with a maximum pressure of 60,000 PSI (4,137 bar). Pump power is listed as 37 kW / 55 kW (50 / 75 HP), so check which rating is fitted to the system on offer.
03
Up to 3 simultaneously. All heads draw on the same pump, so the number that can cut well at once depends on whether the system has the 37 kW (50 HP) or the 55 kW (75 HP) pump.
04
The listed positioning accuracy is ±0.05 mm (±0.002 in) and repeatability is ±0.03 mm (±0.0012 in), on linear guides with ball screw drives. Those describe the motion system; the cut edge also depends on speed, abrasive and material thickness.
