Overview
The Flow Mach 500 1020 is a compact, high-precision CNC abrasive waterjet cutting system from Flow International, featuring a 1,000 mm x 2,000 mm cutting envelope designed for precision job shops, aerospace suppliers, and manufacturers working with tight-tolerance parts in demanding materials. The Mach 500 series represents Flow's highest-accuracy waterjet platform, and the 1020 table size is the entry point into that product line — bringing Mach 500 technology to shops that prioritize accuracy over table area.
Flow International, based in Kent, Washington, is one of the pioneers and global market leaders in industrial waterjet cutting technology, having developed and commercialized abrasive waterjet cutting over several decades. The Mach 500 series embodies Flow's engineering focus on cutting precision: the machine uses a heavily reinforced bridge structure and precision ground linear guide rails with preloaded carriages to achieve positional accuracy that meets the demands of aerospace and medical parts with tight geometric tolerances. The machine's Dynamic Waterjet XD cutting head — Flow's proprietary 5-axis head technology — is available as an option on the 1020, allowing bevel cutting and taper compensation for the most demanding applications.
The Mach 500 1020 is compatible with Flow's HyperPressure pump technology, operating at up to 94,000 psi (6,480 bar) — higher than most competitor waterjet systems. This ultra-high operating pressure produces a faster, more focused abrasive jet that cuts significantly more quickly than conventional 60,000 psi (4,100 bar) systems, particularly in thin-to-medium-gauge material. The higher pressure also reduces abrasive consumption per unit of cut length, lowering operating costs on production runs. Flow's Intelligent Boost Technology automatically manages pump pressure to optimize cutting speed and operating efficiency across different material types and thicknesses.
The control system on the Mach 500 1020 is Flow's proprietary FlowMaster controller, widely regarded in the industry for its ease of use, integrated CAM capability, and advanced features including Precision Waterjet Nesting for sheet optimization, automatic tool path generation from DXF/DWG files, and real-time machine monitoring. FlowMaster includes taper compensation algorithms that use the machine's speed and material parameters to predict and correct for jet taper, producing square cut faces without slowing down excessively.
The Mach 500 1020 is ideally suited for precision aerospace suppliers, defense contractors, medical device manufacturers, and high-end job shops producing parts that must meet engineering drawings with tight dimensional and geometric tolerances. Its compact 1 m x 2 m table size makes it practical for smaller facilities that cannot accommodate a full-size waterjet but need the accuracy and material versatility that only waterjet can deliver. The Mach 500's combination of HyperPressure capability and precision mechanical construction puts it in a class above standard-pressure entry-level waterjet systems.

Strengths & Limitations
Strengths
- HyperPressure at 94,000 psi cuts faster and uses less abrasive than standard-pressure systems
- Industry-leading ±0.025 mm positioning accuracy for tight-tolerance precision parts
- FlowMaster controller is intuitive, feature-rich, and widely respected in the industry
- Compact 1x2 m envelope fits in smaller facilities without sacrificing Mach 500 precision
- Optional Dynamic Waterjet XD 5-axis head available for bevel cutting and taper correction
Limitations
- Small cutting area limits part size and sheet utilization compared to larger-format waterjets
- HyperPressure pump seals require more frequent replacement than standard-pressure pumps
- Premium pricing reflects Mach 500 technology — not the most economical entry-level waterjet

Frequently Asked Questions
01
HyperPressure refers to Flow's ultra-high-pressure pump technology operating at up to 94,000 psi (6,480 bar), compared to the 60,000 psi standard for most waterjet systems. At higher pressure, the waterjet stream is faster, more focused, and more energetic — cutting up to 50% faster in some materials, using 40% less abrasive per cut, and producing a smoother cut surface finish. The benefits are most significant in thin-to-medium thickness hard materials.
02
The Mach 500 1020 achieves positioning accuracy of ±0.025 mm (±0.001"), which is among the best available in production waterjet systems. This is achieved through precision ground linear guide rails, preloaded carriages, and a rigid bridge structure. Comparable standard-pressure waterjet systems typically achieve ±0.05 mm — the Mach 500 cuts this tolerance in half, which matters significantly in aerospace and precision parts applications.
03
The Mach 500 1020 cuts all standard waterjet-compatible materials: steel, stainless steel, aluminum, titanium, inconel and other nickel alloys, copper, brass, glass, ceramic, stone, carbon fiber composites, and plastics. Its HyperPressure capability makes it particularly effective on hard, dense materials like titanium, tool steel, and thick stainless where standard-pressure systems are slower.
04
Yes, Flow's Dynamic Waterjet XD 5-axis cutting head is available as an option on the Mach 500 1020. The Dynamic Waterjet XD adds A and B axis rotation to the cutting head, enabling bevel cutting, weld preparation angles, and active taper compensation that produces true vertical cut faces on standard parts. It is specified at order time rather than retrofitted to existing machines.
05
The Mach 500 1020 uses the same precision mechanical platform, HyperPressure pump technology, and FlowMaster controller as larger Mach 500 table sizes. The 1020 is the smallest worktable in the series, offering the same accuracy and cutting performance in a footprint suited for smaller shops or facilities where floor space is constrained. Shops that grow into larger throughput requirements can move up to 1530 or 2030 table sizes within the same Mach 500 series.
