Various inspection and measurement resources help a moldmaker produce tooling for tiny molded parts.
Milling complex forms in hardened tool steel involves more than just fast, light cuts, says this maker of medical-related injection molds. Here are some of the ingredients of an effective hard milling process.
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.
Video captured with a microscope shows that a full-scale machining center is capable of micro-size milling work.
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.
A wire EDM machine designed for micromachining uses negative air pressure to thread the fine wire.
