Machines with linear motors instead of ballscrews have increased productivity for one die maker.
... not to mention grinding with air. Thanks to high speed spindles powered by shop air, this job shop expands the work its VMCs can do.
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.
High spindle speed is not needed for high productivity, particularly with the right choice of cutting tool types. Techniques described in this tutorial video relate to plunge roughing, high feed milling and slotting.
Even in aluminum, plunge roughing can be an effective way to realize high productivity.
Footage shows roughing at 48 cubic inch per minute on a standard-speed machining center.
Demonstation illustrates the kind of metal removal rate that is possible in aluminum at dynamically stable speeds.
This video of machining Inconel at a fast metal removal rate shows the effect of constant-engagement-angle milling.
This video of machining titanium at a fast metal removal rate shows the effect of constant-engagement-angle milling.
Here is an introduction to machining center spindles designed for high speeds, with practical tips for using these high speed spindles effectively.
