How much does the Flow Mach 300 cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from Flow International. Configuration moves it a long way.
Overview
The Flow Mach 300 is a 60,000 PSI (4,137 bar) waterjet cutting table with 12 in (305 mm) of Z travel on a 1.5 m wide bed. Two sizes are listed: 2015, with a 6'-6" × 5' (2 m × 1.5 m) work envelope, and 3015, with 10' × 5' (3 m × 1.5 m).
The tall Z is what separates it from the tables numbered below it. The Mach 150 and Mach 200c both stop at 8 in (203 mm). Maximum cutting thickness here is 150 mm (6 in), so the 12 in is not there for thicker plate. It is clearance: room for fixtures, for formed or boxed parts, and for retracting over clamps.
Accuracy matches the Mach 200c. Positioning accuracy and repeatability are both ± 0.001 in (± 0.025 mm), and ballbar circularity is ± 0.003 in (± 0.0762 mm). Rapid traverse is 472 in/min (11.9 m/min) with 0.075 g of acceleration, midway between the 0.05 g of the Mach 150 and the 0.1 g of the Mach 500.
Bed width is the limit to check. At 1.5 m, neither size takes the 2 m wide plate that the 3020 and 4020 sizes of the Mach 200c accept. Flow's table also names no pump for the Mach 300, so the pump model and its power belong in the quotation.

Strengths & Limitations
Strengths
- 12 in (305 mm) of Z travel, against 8 in (203 mm) on the Mach 150 and Mach 200c
- ± 0.001 in (± 0.025 mm) positioning accuracy and repeatability
- 0.075 g acceleration, above the 0.05 g of the Mach 150
- ± 0.003 in (± 0.0762 mm) ballbar circularity
Limitations
- Both sizes are 1.5 m (5') wide, so 2 m plate does not fit
- Only two sizes, 2015 and 3015; the Mach 500 runs to 4 m × 8 m
- Maximum cutting thickness is 150 mm (6 in), half the 12 in (305 mm) Z travel
- Rapid traverse of 472 in/min (11.9 m/min) is below the 500 in/min (12.7 m/min) of the Mach 200c

Frequently Asked Questions
01
Two. The 2015 has a 6'-6" × 5' (2 m × 1.5 m) work envelope and the 3015 has 10' × 5' (3 m × 1.5 m). Z travel is 12 in (305 mm).
02
Maximum cutting thickness is 150 mm (6 in) and Z travel is 12 in (305 mm). The difference is working height above the material: space for fixtures and clamps, and for parts that are tall without being thick, such as formed sections.
03
Accuracy figures are the same: ± 0.001 in (± 0.025 mm) positioning and repeatability and ± 0.003 in (± 0.0762 mm) ballbar circularity on both. The Mach 300 has 12 in (305 mm) of Z where the Mach 200c has 8 in (203 mm). The Mach 200c is slightly quicker at 500 in/min (12.7 m/min) against 472 in/min (11.9 m/min), and its 3020 and 4020 sizes are 2 m wide where the Mach 300 is 1.5 m.
04
Rapid traverse is 472 in/min (11.9 m/min) and acceleration is 0.075 g. Acceleration governs how quickly the head recovers speed after corners, so it matters most on parts with many short segments.
