Hi All,

I've just finished updating my website with the start of my construction log for my milling machine project. Comments are most welcome.

Pat,

Very slick! You do a nice job with the commentary explaining the why's and wherefore's for your choices. The site has a nice look and feel to it as well. When I get a little more time (getting ready for work right now) I'm going back to look at the rest of the site. Make sure you let us know when updates are added! Shaping up (pun) to be a nice machine. Thanks for sharing...

nice start. I look forward to seeing the progress on it. what spindle(s) are you going to use?

Hi Jimbo,

I am initially going to use a Taig ER16 spindle with a vari speed DC motor, but I am also considering rolling my own and incorporating an auto tool changer. Not sure really - I am sort of going to cross that bridge when I get there.

Hi Guys,

I posted some updates on machining the bearing blocks for the axes.

Pat,

Again, very nice. I'll be looking forward to the next round of updates!

Hi Guys,

I have finished the bearing blocks - more pics at:

Next will be the ballnut housings....

Cheers,

gimbal...any drawings you would be willing to share on the bearing blocks....I'm at that stage of thinking about how to design these....I'm turning the ends of my ballscrews at this moment....the end bearing blocks seems quite simple....just a cavity for a bearing and maybe a delrin deflector...

Hi ViperTX,

I have updated the Bearing Blocks Pt I article (http://www.gimbal.com.au/content.aspx?name=cnc-mill-bearing-blocks) to include a link to the drawings.

Couple of things:

1. These blocks are to suit 7200B Angular Contact Bearings (30mmOD/10mmIDx9mm)- sizes would have to be adjusted for different size bearings
2. A spacer is required a smidge smaller that the bearing OD and thick enough that the outer races are compressed when the cap is screwed on - make sure the bore in the spacer is big enough to clear the inner races of the bearings.

Enjoy!

Cheers,

Pat

Pat, thank you for being so generous and sharing! It will greatly reduce my design time.

hi Gimbal

very nice work and site is A1

just out of curiousty where in Australian are u located ?

cheer

Wow, that's starting to look pretty sharp! Don't know how I missed your last update. keep the updates coming.

Thanks -

I am located in Mitcham Victoria. I am doing the head now and I took some more pics last nite so I'll do another update soon.

Hi Gimbal,

WOW. Your mill looks really nice. Very nicely done. Can't wait to see it all finished up.

Hey Gimbal very impressive, hey I have started a manual mill project and for the z axis do you think I could go with something like this? http://cgi.ebay.com/THK-Integral-Vertical-Slide-Rail-with-Accessories_W0QQitemZ7605535873QQcategoryZ55826QQrdZ1QQcmdZViewItem

ZipSnipe,

I would hesitant to use this assembly for a manual machine simply because the ballscrew can be back driven, so you would need some sort of locking mechanism for manual use.

For CNC it would be great.

Note that there have been updates on www.gimbal.com.au, but it is down at the moment whilst I change ISPs :-)

Roger that, I found a Gimbal dovetail single axis table that I,ll probably use.

Hi Guys,

More progress - check it out at www.gimbal.com.au/content.aspx?name=cnc-mill

Cheers,

Pat

Could you post some CNC working video? thanks you very much

Best Regards

Sure - I'll take some video and post it over then next week or so.

thanks gimbal, could you post draw of your ball screw support?

Hey mate,

a video would be cool, what happend.
every once in a while i take a look at the website, never a picture off the mill with a spindle or some work done.

good luck with the machine and thanks for the inspiration.

Regards,
