Video of a Really Cool Bar (-Fed Machining Center)
See a five-axis, bar-fed machining center creating a complex sample part complete from barstock.
Bar-fed machining centers are just plain neat. They allow complete, unattended production of all sorts of intricate workpieces out of barstock. The sample part shown in this video, which features a serrated jaw for a medical clamp, was created on a five-axis Willemin-Macodel 408MT machine. The video does a good job of demonstrating the multi-axis movement and backworking capability these atypical machines offer.
