Machining internal threads in difficult materials is challenging, especially when hole diameters are small. Thread milling offers advantages for these applications that are important to consider.

 Smooth finish comes from balanced cutting parameters, as this video explains.

 This footage on a small drilling machining also includes machining with full-size tools in the same cycle.

Video shows the smooth, quiet, rapid motion characteristic of effective micromilling.

The Makino EDFH1 is a fine-hole EDM machine capable of machining holes as small as 10 microns in diameter using a 6-micron-diameter electrode. One user of this machine is Hummingbird Precision Machine in Lacey, Washington. This video taken at Hummingbird shows how the electrode is loaded.

Video captured with a microscope shows micromachined part.

Video captured with a microscope shows that a full-scale machining center is capable of micro-size milling work.

A wire EDM machine designed for micromachining uses negative air pressure to thread the fine wire.

When milling with tiny tools, changing the length-to-diameter ratio can significantly change the cutting parameters it is possible to achieve.

This video clip illustrates micromilling at a high tool L:D ratio.
