Hi,
I am converting a HM-30 (RF-30 Clone) to cnc, the stock screws have too much backlash and I am looking to go to ball screws, can anyone recommend a supplier in Australia or am I better off to order from the US?

I need to ask a few questions so a company that does CNC would be a great help.


thanks

I got 16mmx5mm pitch ballscrews for my project from www.appliedauto.com.au in Melbourne. Cheapest I was able to find - equivalent THK was 3-4 times the price.

What sort of money Gimbal

Iv'e been looking at HomeshopCNC prices which seem real good till you change
the dollars and add freight :rolleyes:

2 x 460mm travel $155 odd each
1 x 360mm travel $148 odd each
ballnuts $115 each
This included machining to ISEL catalog standard.

Figure $270 per axis

This was June 2005 so YMMV - at the time this was well worthwhile to me as second hand ebay 20mmx5mm pitch screws were worth about this when freight was included.

Hi Guys,

I would recommend contacting Action Bearings.
(http://www.actionbearings.com.au/)

A mate of mine just converted his mill to rolled ball screws with 2 nuts on each axis and I'm positive that the total cost was below $500.

This was for 3 pieces of thread and 6 ball nuts.

It was the Kensington branch that was contacted and the sales rep was Brett.

If you purchase from them maybe you could mention that Jayson from Horsham recommended them.

I don't get anything out of this however I have pestered them quite a bit and they haven’t got any of my money... yet. A few purchasers might make up for it a bit.

I will definitely be purchasing from here once my finances allow.

Regards,

I would be interested in following your progress with this project as I am interested in converting my HM-35 to CNC. Will you be makng this a project on the web pages here?

Guy's

I can back splint up on his recommendation for the ISEL gear from Applied Auto, I use the 16mm screws all the time and you can adjust the backlash right out of the nuts with their neat little side clamp system :cheers:
