Thread cutting in chinese ballscrew

[komatias]

Ok, though Hoss's plans don't specify any machining of the nuts in so far as I can see. I think he must rely on single point of contact being adequate to prevent axial travel since the bearings are held captive radially by the housing, but point taken the squarer the better!

Neil I agree... 1mm pitch would be much better as less material would be removed meaning easier cutting hopefully and I could buy lock/jam nuts specifically, good idea!

Perhaps if I set up my rotary table in the vertical position I could work out some way to hold the die somehow with the tailstock and allow it to slide forward as I turn the ballscrew in the chuck? Crazy or totally crazy?

So if you are following the usual dimensions you will find the a M10x1.5 does not pass over the 8mm section. We typically use M10x1.0 as it also allows you to get a finer adjustment on the locking nut.

In answer to your original question, if you have rolled screws, then yes, you can use a die. I have done this with a M10x1.0 and as long as you are square on, you will be fine. You may need to use more lube than usual here.
