X axis drive

**petesos** · 13-08-2020

Right guys
You guys been in this game for a long time so am asking for your recommendations ,
The x axis screw on this cheap chinky machine is 12 mm diameter trapezoidal and am looking for a good replacement ballscrew as i will replace all the ballscrews as they wear .
What would be the best upgrade { ballscrews } from the cheap screws that are on there already, any ideas please

You are not going to like this reply but it's the honest truth.!! . . . You Can't make a silk purse out of a sow's ear. !

So don't waste your money trying to upgrade this machine. Just use it as it is and save the money to put to another machine which is designed correctly and uses ball screws etc.

Cant beat honesty Jazzcnc.
Yep i know what your saying , I have just had a reply from the sales girl who i bought the machine from in Switzerland that they could send the new replacement part and if i could deposit 280 quid sterling into there account she would send me the part i want.

My wife was so pleased with me that i only used the F word eight times in the return email.

.

So yep that is my course of action make do with it till something better comes up . but need to find a way of taking the backlash out in the meantime so am going to do a strip down

I will presume you know the machine type Jazz, and that your silk purse comment is warranted ,
But would it really be so hard to replace with Chinese Ball screws

Yes, I do that's why I posted what I did but you obviously don't otherwise you wouldn't have linked to a ball screw which has end machining for a BK bearing when this machine doesn't have any.!

How difficult is like saying how longs a piece of string.? For me, it would be a simple thing because I'm kitted up and have experience but I suspect from the OP's post he isn't and doesn't so maybe not so easy.? But in either case, it's still a PIG and no amount of lipstick is going to change that.!

Use it to learn on, sell it, and move on is the best thing to do with these machines IME.!

i would just replace with the same as you have got now. go to somewhere like accu.co.uk they have lots of trapezoidal bar and nuts to go with them
