Cutting narrow incisions with ultra-high precision in high density materials using waterjet technology requires a specific waterjet cutting process, the Fine Abrasive Waterjet process (FAWJ). The first FAWJ cutting head was developed by Water Jet Sweden in 2008.
Fine Abrasive Waterjet bridge the gap
Waterjet cutting is a common method for processing parts in high density materials as aluminum, stainless steel, titanium and carbon composites. FAWJ cutting process bridge the gap between micro laser and EDM cutting and brings water jet cutting into the field of micro part processing.
To enable such level of precision you need two things. (1) a cutting head and cutting process for FAWJ cutting and (2) a machine built for extreme accuracy. The NCM 10 Micro from water jet Sweden fulfil those requirements.
FAWJ cutting process with 0.2 mm incisions
The first micro waterjet cutting head was developed by Water Jet Sweden in 2008. It is a high precision cutting tool producing one of the most precise abrasive water jets in the world. The unique cutting head enables an abrasive jet diameter down to 0.2 mm. The FAWJ cutting process requires very fine abrasives of 230-240 mesh and a special CNC controlled dosage abrasive feeder.
Machine table designed for ± 0.008 accuracy
To reach the levels of accuracy required to micro part manufacturing the NCM 10 water jet has a number of unique design features to create a rigid table that withstand temperature fluctuations.
Mineral Casting Bearlit table frame – A table frame made of a composite material with exceptional stiffness that withstand vibrations and temperature fluctuations. The frame is integrated in the machine construction and motion system as a complete unit.
Rubber suspended stainless steel water catcher – the free-standing catcher solution avoid that vibrations and temperature variations influence the cutting process. Stainless steel makes it maintenance free.
Renishaw Invar Scale in X and Y – With a Renishaw Absolute Linear Encoder fitted in both X and Y axis you have a micrometer scale with extremely low expansion coefficient and Ultra high resolution
Prepared for any kind of fixtures
The palettized cutting table make it easy to install fixtures and presses for different types of machining. Maximum table size is 1x1 m which covers most cutting application. The cutting table is fixed into the table frame to enable ultra-high precision cutting.
"There are many suppliers who state that they offer micro cutting machines but there are not many who can offer a true micro part cutting tool with 0.2 mm incision combined with ± 0.008 accuracy" summarize Tony Rydh, co-founder and CTO at Water Jet Sweden.
