Electronic Lead Screws – Not Just For Threading Anymore

on


An digital leadscrew is an more and more common undertaking for small and mid-sized lathes. They dispose of the necessity to swap gears out and in to realize the right ratio between spindle pace and gear carriage translation, and that makes threading a snap. However well-designed digital leadscrews, like this one from [Hobby Machinist], supply a lot extra than simply simple threading.

The very first thing that struck us about this construct was the polished, skilled look of it. The enclosure for the Nucleo-64 dev board sports activities a pleasant TFT show and an IP65-rated keyboard, in addition to a beefy-looking jog wheel. The spindle pace is monitored by a 600 pulses-per-revolution optical encoder, and the lathe’s leadscrew is powered by a closed-loop NEMA 24 stepper. This mixture permits for the fundamental threading operations, however the addition of a powered cross slide opens up a ton extra performance. Inner and exterior tapers are a couple of keypresses away, as are boring and turning and radius operations, each on the appropriate and on the left. The video under reveals radius-cutting operations mixed to show a sphere.

From [Hobby Machinist]’s to-do checklist, it seems to be like filleting and grooving shall be added sometime, as will a G-code parser and controller to make this right into a bolt-on CNC controller. Inspiration for the construct is claimed to have come partially from [Clough42]’s electronic leadscrew project from a couple of years again.
