Precision through specialization

Where the confidence comes from

This confidence is grounded in measured performance and feedback from customers who have evaluated alternative systems.

Finepart was among the pioneers that brought micro abrasive waterjet machining to market, alongside Microwaterjet. Members of our development team bring 35 years of waterjet technology development experience, including the past 20 years focused on microcutting for precision engineering applications. This experience shapes our machine design, application methods, and customer training.

What the specifications tell us

As micro abrasive waterjet machining has developed into a distinct market segment, it has attracted traditional waterjet manufacturers alongside the dedicated micro cutting specialists. Finecut’s focused development has led to positioning accuracy and repeatability of ±1.5 µm for newly manufactured three-axis systems, determined according to ISO 230-2. The table compares published specifications; measurement methods and conditions may differ.

Positioning accuracy describes how closely an axis reaches its commanded position; repeatability describes how consistently it returns. In repeat production, repeatability can be more important: stable, systematic errors can often be compensated for, whereas part-to-part variation cannot be removed by a fixed correction. Both specifications matter, but neither alone determines finished-part tolerances. These also depend on fixturing, thermal stability, and the cutting process.

Experience across the complete tolerance chain

At Finepart, we approach micro abrasive waterjet cutting as a precision machine-tool application. Finecut’s architecture addresses the complete tolerance chain, from workpiece fixturing and structural and thermal stability to motion-path accuracy and cutting-process consistency. Accurate motion provides the foundation; specialized process knowledge makes it productive.

Finepart combines deep expertise in waterjet technology with two decades of experience delivering machines for precision applications. This sustained specialization concentrates our development work and application experience on the challenges that matter at the micrometer scale. The result is a combination of machine technology, process knowledge, methods, and practical training refined through years of solving demanding precision problems. Close customer collaboration turns this understanding into practical solutions and, over time, improvements in both the technology and the process.

Let your application decide

When a customer brings us a challenging drawing, we want to understand which dimensions matter for functionality, how they will be measured, and whether the goal is a prototype or repeat production. These questions define a useful test and a credible route into manufacturing.

We encourage you to put Finecut and our competitors to the same test: the same material, representative geometry, and agreed acceptance criteria. Compare dimensional accuracy, taper, edge quality, and consistency across several parts, alongside cutting time and production conditions. Ask how the process will transfer to your team—and how future developments and upgrades to the system platform can benefit your investment.

Our confidence comes from experience, customer feedback, and measured results. We welcome demanding questions and the opportunity to earn your confidence in your own application.
