Ball screws

[Ian HartParticipant @ianhart94481]

Hi

 

I have a C1 size lathe and have installed stepper motors and a timing disc, and I am now researching the installation of ball-screws to eliminate  backlash.

Has anyone knowledge or experience that will guide me?

I would visit http://www.arceurotrade.co.uk/ They supply ball screws and have links to various projects and forums which have descriptions and hints on this kind of thing.  Rob

If you look in the Nachi catalogue, which covers most of the standard bearings. They make bearings like every other manufacturer. You’ll find single nut ball screws, double nut screws, precision screws, etc etc from 14mm dia up to 80mm, in various leads, plus the support bearings etc.

 

There is also an entirely separate ball screw catalogue which will I imagine list tech specs and installation requirements.  (And possibly a wider range of products?)

 

I should google Nachi, Hoffman, SKF etc.See what the makers recommend for their bearings as a first port of call. Then when you have found something reasonable, ring the makers tech services dept. You cannot beat talking to the makers of these things – they have a habit of knowing what the thing was built to do.

Some of these precision ball screws can be tolerably expensive.

 

RHP/SKF standard type brgs for the back of a Myford. £5 each +vat. (7205 or whatever).

 

Precision version, dimensionally interchangeable etc – £50 + vat. (each)

 

I just mention it in passing!!!!!
