Micromachining Powder Metal on a VMC
By refining its micromachining process for powder metal tool steels, this shop has reduced production costs, lead times and secondary bench work for complex tooling components.
Too Small To Touch
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
Fine Wire Is Just Fine
As parts get smaller and smaller, using EDM wire as small as 0.001 inch in diameter to cut these workpieces becomes an attractive option—actually, the only option.
An EDM plus a robot makes a dynamic duo. A graphite mill plus a robot makes another. Put them all together in one shop and you have a radical new way to speed mold production.
Anti-Electrolysis Is Pro EDM
A new breed of power generators for wire EDMs has options for reducing, even eliminating, one of the unwanted side effects of this very versatile metalcutting process.
Electrode Mill Hits 36,000 RPM
Today's CNC EDMs burn cavities faster than ordinary milling machines can feed them with electrodes, and so the demand for high-speed graphite machining centers has opened up an opportunity that machine-tool builders have begun to fill.
