Overview

The Flow Mach 300 is a performance-class waterjet cutting system that bridges the gap between Flow's entry-level Mach 150/200 series and the premium Mach 500 and NX Pro platforms. Available in two table configurations — 2015 (2 x 1.5 m) and 3015 (3 x 1.5 m) — the Mach 300 targets shops that need precise waterjet cutting in a compact footprint. Its 1.5-meter table depth makes it particularly well-suited for shops with limited floor space where a full 2-meter-deep table would not fit.

The Mach 300 supports multiple pump technologies ranging from 60,000 PSI (4,150 bar) with HyPlex Prime and MotoJet pumps up to 94,000 PSI (6,500 bar) with the HyperJet pump. This HyperJet compatibility sets the Mach 300 apart from the entry-level models, enabling 30-50% faster cutting speeds that significantly improve productivity on harder materials and thicker stock. Positioning accuracy and repeatability are both +/- 0.025 mm (+/- 0.001 in), matching higher-end Flow platforms.

The machine features 305 mm (12 in) Z-axis travel for cutting thicker materials, rapid traverse of 11.9 m/min (472 in/min), and both FlowMaster and FlowXpert software suites. The Mach 300 supports Dynamic Waterjet and Dynamic Waterjet XD cutting head options for taper compensation and 3D bevel cutting, adding capability that entry-level models cannot match.

The Mach 300 competes with the OMAX 55100, WardJet Z-Series, and Bystronic ByJet Smart in the mid-performance waterjet segment. New systems price between $150,000 and $300,000 depending on table size, pump selection, and cutting head options. With HyperJet pump compatibility and tight positioning accuracy, the Mach 300 is the entry point to high-performance waterjet cutting in Flow's lineup.

Strengths & Limitations

Strengths

HyperJet 94,000 PSI pump compatibility enables 30-50% faster cutting speeds than 60,000 PSI systems on hard materials
Compact 1.5-meter table depth fits into shops where full 2-meter-deep machines would not fit, without sacrificing cutting area length
Positioning accuracy and repeatability of +/- 0.025 mm match premium platforms at a mid-range price point
12-inch Z-axis travel handles thicker materials than the 8-inch travel on entry-level Mach 150 and 200 models
Dynamic Waterjet XD head option adds 3D bevel cutting and taper compensation for advanced applications
Flow's global service network ensures parts availability and technical support worldwide

Limitations

1.5-meter table depth limits maximum part width compared to 2-meter-deep tables on the Mach 500 and NX Pro
Two table size options (2015 and 3015) provide less flexibility than the Mach 500's five configurations
HyperJet 94,000 PSI pump adds $50,000-$80,000 to system cost and increases maintenance complexity and consumable costs
Abrasive consumption of $15-$25/hour in garnet costs remains a significant ongoing expense

Best For

Shops needing high-performance waterjet cutting in a compact footprint where 2-meter table depth is too large Fabricators ready to step up from entry-level waterjet to HyperJet 94,000 PSI cutting speeds for improved productivity Aerospace and defense shops cutting titanium, Inconel, and hardened alloys where 94K PSI dramatically reduces cut time Precision fabricators requiring +/- 0.025 mm accuracy on waterjet-cut parts for assembly-critical applications Job shops seeking a versatile mid-range waterjet that can grow from 60K to 94K PSI pump as production demands increase

Frequently Asked Questions

01 What does a Flow Mach 300 cost?

New Mach 300 systems price between $150,000 and $300,000. A 2015 table with HyPlex Prime 60K PSI pump starts around $150,000. The 3015 table with HyperJet 94K PSI pump and Dynamic Waterjet XD head reaches $300,000. Operating costs run $20-$40/hour depending on pump pressure and abrasive consumption.

02 Why does the Mach 300 have a 1.5-meter table depth?

The 1.5-meter depth is designed for shops with limited floor space where a full 2-meter-deep table would not fit. Many shops have existing equipment layouts that constrain available depth. The narrower table still provides 2 or 3 meters of cutting length, which handles most standard sheet sizes.

03 How does 94,000 PSI compare to 60,000 PSI?

HyperJet 94,000 PSI cutting is 30-50% faster than standard 60,000 PSI on most materials. The higher pressure produces a more focused cutting stream with less kerf width and better edge quality. The trade-off is higher pump cost, more frequent seal changes, and slightly higher consumable expenses. For shops cutting hard or thick materials regularly, the productivity gain justifies the cost.

04 What is Dynamic Waterjet XD?

Dynamic Waterjet XD is Flow's 5-axis cutting head that tilts the nozzle to compensate for the natural taper that waterjet cutting produces. Standard waterjet cuts have a slight V-shape; the XD head corrects this to produce square edges. It also enables bevel cutting up to 60 degrees for weld prep and angled features.
