Walter MICRO

The Helitronic Micro features a linear motor/torque drive technology. But the Micro has a radically new seven axis layout optimized for grinding micro tools. For example, the Micro has an X2 axis that automatically moves the tool to center during a grind, thereby achieving better accuracy on corner radii and ballnose forms on even the smallest tools. The machine includes a three-spindle grinding head for up to twelve wheels. And the Micro's new B-axis positions the wheel to grind clearance angles with the samepoint on the wheel throughout the grind. These features help to speed up grinding by 30% and improve surface finishes by up to 50% than machines with conventional ball-lead screws. The optimal range for high precision production is from 0.020 - 0.50 inches (0.50 - 12.7 mm) in diameter, though the machine is capable of handling both smaller and larger tools. The machine also features an integrated FANUC robot loader for fast automatic tool c hanges. Plus the 1,000 RPM A-axis workhead can handle precise cylindrical grinds. That's particularly useful when making step tools.
