Single Point Thread Cutting By Depth Metric Threads On An Imperial Lathe

Cutting Metric Threads On An Imperial Lathe | The Hobby-Machinist

Cutting Metric Threads On An Imperial Lathe | The Hobby-Machinist In this video i cut a metric 1.5mm single point thread on an imperial lathe with an 8 tpi lead screw. i will also demonstrate how to cut the tread by depth using the compound. If your lathe has an "inch" lead screw and the proper change gears (as most do), you can cut metric threads. however, you have to do it differently than inch threads because you'll have to leave the half nut engaged throughout the whole process.

Cutting Metric Threads On An Imperial Lathe | The Hobby-Machinist Folks may find the thread chart below useful for selecting change gears when cutting metric threads on an imperial lathe. the driver gear is the output from the tumbler set. Set the depth for the next cut, just as you always do, and repeat the process until the thread is complete. it's easy to make mistakes even with standard inch threading, and you now have a couple more things to remember. With a larger lathe and more rigid setups, full two sided cutting is easily achieved, but on smaller lathes, the finish of the thread is usually a lot worse as the chatter is increased all down the thread, especially as the thread gets deeper. Single point threading stands as one of the most challenging yet rewarding operations in lathe work. this ancient art of copying the lead screw's precision onto your workpiece demands patience, practice, and proper technique.

I've just been watching a series of videos by keith fenner working on a rutland lathe on which lots of features are identical to a wt lathe i have also sold under the tida name. When cutting metric threads on a lathe with an imperial lead screw you are always told you can't disengage the half nuts and you have to reverse the lathe leadscrew to move the carriage/tool back to the start for the next pass. Plunge cutting, aka cross slide threading, requires that the cutting tool widen the full shoulder width with each increasing depth of cut. if you're coming in at 30*, you're only widening the root of the cut as you increase depth.
