Mini lathes can be found for an entire bunch of producers they usually’re nice method to get began with turning steel. However as helpful as they’re, they lack lots of the options you’ll discover on “actual” industrial lathes. Mini lathe lead screws are significantly irritating and most of them use difficult gears which can be annoying to regulate. This digital lead screw improve fixes all of these issues and is without doubt one of the finest mods you are able to do to a mini lathe.
The lead screw strikes the carriage alongside the Z axis and is linked to the spindle, so rotating the spindle a single time may, as an example, transfer the carriage precisely 0.5mm. That is essential for operations like single-point threading, as a result of that 0.5mm is the thread pitch.
Just about all mini lathes hyperlink the lead screw to the spindle with a collection of “change gears,” which the operator should swap out to realize the specified pitch — or to make use of the lead screw as an influence feed. That course of is cumbersome and time-consuming. And generally it isn’t even attainable to rearrange the gears to realize a particular pitch.
An digital lead screw solves all of that. It screens spindle rotation after which makes use of a motor to rotate the lead screw, with a management interface that lets the person set no matter arbitrary pitch they need.
NanoELS H5 is a DIY digital lead screw controller designed by Maxim Kachurovskiy. This video from FWFworks covers the construct and set up. It ought to value round $170 to construct a NanoELS H5 and most of that’s for the great 5” Nextion show.
Kachurovskiy designed the NanoELS H5 round an ESP32-S3 improvement board. It screens spindle rotation by means of an absolute rotary encoder, then drives a stepper motor that turns the lead screw. That fancy Nextion show lets the person set the lead screw parameters for the job at hand.
So if in case you have a mini lathe and are uninterested in coping with these gears, this can be a no-brainer.
