Over the past 20 years, Stewal has made significant investments in 3D high-speed milling machines, 5-axis milling machines, and turn-mill centers.

Within the realm of 5-axis milling machines, a deliberate choice was made to invest in miniature milling. The objective: to achieve high levels of detail and precision in small pieces in a repetitive, reliable process. We opted for a Swiss high-dynamic 5-axis milling center. Here, we machine with cutters ranging from 0.3mm to 12mm in diameter and rotate up to 42,000 rpm, 5-axis simultaneously controlled. The milling center is also equipped with full temperature compensation and an automatic changer for 18 workpiece pallets.

This setup enables faster, more accurate, and more automated work, catering to the trend of miniaturization and increasing complexity, across a wide variety of technical materials, including superalloy hardened steels.

Together with our other precision technologies and laser welding, this expertise allows us to offer a complete solution for a wide range of miniature parts with high levels of finishing and accuracy.
