They still don t lie whatever srew it is. The thread on the screw and the mating nut have the same tpi. It s the operator not the srcrew. If one cant count to five and rotate a handle and gets tripped up I think there in for a world of hurt no matter the route you take. Backlash, well learn to use numbers and how to compensate for backlash not guess how many cranks. If The screw from the manufacturer is not built right it s out of this discussion.
You guys and the modern stuff think it s all the bees knees. Ya it s great and I can guarantea they ll be question like the dro says so but my part says different. What s up with that?
Have an imperial or metric scale along your x,and y axes. Oh theres the eighteen inches i need to move so ill mark my axis and then when I look and see that mark is near the eighteen i ll look down at my dial to fine tune. Easy peasy. They don t lie they are mechanically locked. Its all operator.
Id like to see some of you with these lower end dros do some test with some jo blocks (guage blocks) and indicators and see what kind of accuracy you have now with your Dro. Add a cut in there during your testing.
It a luxury and an aid. I don t need a dro I can manage without. Bolt circles and such can all be done mathematically.
Would I like one sure! I ll wait and get by until i can get a decent unit and the shop has caught up a bit.
So here will be another new machinist going right to a dro not learning the basic skills that would force him to learn some math and trig. Which will be all computer aided and you know it s not about this mill its about getting some routes that will help and stay with a person so they can grow not looking for a computer.
My whole argument is why not learn from the ground up. There will be times you ll have to revert doing something the old way because it is all you can work with. Not having the dro forces you to get that pad and pencil out and work thinks out
I Don t think were doing these newbies any good heading down this path from the get go. Will the rotary table have a dro? You know you should revert back to zero then hit your next angle.
Screws don t lie!
Apparently, you've never read the tolerance specs on ACME screws. Whatever. Carry on.
