I always screw cut in the lathe Acme lead screw half nuts for a couple of reasons. 1. being it avoids the cost of a tap which are mouth wateringly expensive here and only likely to be use once so not a good use of resources (cash) 2. Its guaranteed that the screw cut thread will be true to the rest of the half nut especially where it is secured to the cross slide. I did notice that the tap in the tapping machine had a wobble so some sideways strain was put on the tap possibly making it cut a few thou larger. and not true to the machine surfaces. I have cut h/nuts as small as .625in (a Myford lathe lead screw size) Grinding a tool that small can be a bit of a challenge especially side clearance which has to be spot on or the tool will not cut and only rubs. The most successful way I have found of forming a accurate tool profile is by using a tool and cutter grinder fitted with a multi position vise. A Shadow Graph machine would be handy here to check the profile and size. I grind the tool just a few thou under size, on the width which allows me to get a near perfect fit by tweaking the compound slide.

Had the occasion to drill and tap some heavy dimensional copper once. Tried all of the conventional tapping and cutting fluids, even tried kerosene (recommended by a machinist friend), but to no avail. Wound up twisting off several drill bits and breaking three taps. Finally, by accident noticed the jug of bar and chain oil used in the chainsaw, decided to give that a try. Finished the job with one bit and one tap. I would have never thought as sticky as that stuff was (akin to STP oil treatment), that it would have worked. But it's stickiness must have been what was needed to counteract the soft gummy nature of electrical grade copper.

Back before expensive tandem acme taps were commonly available, we would have rough single pointed that size ACME thread in the lathe, and finished it up (also in the lathe), with a conventional single section ACME tap to produce final size. I noticed the run out while you pushed your tap through the bronze. Single point threading, then finishing with a tap in the lathe, reduces any possible thread run out relative to Nut OD.....if that matters.

I think they're a lot more durable than typical threads. That would mean they're stronger, and less likely to wear out and cause slop over time.

@hughmac13

Square threads offer the least friction and are the most efficient thread form, which is why they are used for precision lead screws. However, square threads are difficult to cut, because the cutting tool-whether single point, tap, or die-cannot have rake or relief angle, and cutting-tool life suffers when cutting square threads. Trapezoidal threads are stronger than square threads and offer better wear characteristics, while also being relatively efficient, so that they are also used widely in lead screws as well as in power-driving screws, like vises and jackscrews. I'm not sure why square screws would have been more popular in the past. Perhaps machinists and engineers simply hadn't thought of a trapezoidal thread form yet.
@GregBadabinski
2 жыл бұрын
Square threads are extremely difficult to machine properly. They're theoretically the best threads out there in terms of strength, and I think their backlash characteristics are quite good, but ACME is good enough for most things. I also seem to recall that square threads were less forgiving of wear. Like, they take a long time to wear out, but they don't tolerate wear as well as ACME threads do. Full disclosure, I'm a dingus and a hobbyist who's just really interested in this stuff, so please do your own research, don't trust what I'm saying.

SQUARE THREADS are not self centralizing like vee thread forms. They are chosen for high end machine tools for lead and feed screws because they will tolerate radial misalignment, evident when slideways develop some wear. That means, when axis plane alignment starts to deviate from nominal, this does not cause the screw to bind like a vee form screw would. It is a dis-service to a fine lathe to change the threadform to Acme. It is not difficult to tap threads to renew a nut. It takes more skill to grind a threadform on a toolbit and single point a female thread. I would have gone a different way on this project, but we all have our own path.
