JLT,

I really like that ATC.

I was looking at the site you posted http://www.hightechsystemsllc.com/index.htm , I understand how the tool (endmill, etc...) keeps from slipping in the holders, with a small set screw.

How does the holder keep from slipping (rotating), in the actual toolchanger? The toolchanger does not look like it would provide enough clamping preasure to keep the tool holder from slipping, I don't see any type of flat on the toolholder to give a positive stop. I may be wrong, I'm just really interested in that product (toolchanger).

It looks like you have a great setup going on in that video!

Any chance of a longer video, with some cutting and maybe a couple of toolchanges?

Also did you see the "Drill Chuck Holder" they have? http://www.hightechsystemsllc.com/in...es/Page513.htm

Thanks for sharing your cool project.

Working on a longer video.
Didn't see the Drill Chuck. Thanks

Great thanks!

I have the DXF file i can post later.

Wow I'm blown away. Your router looks cool and colossal in some of the pics. The automatic tool changer & video is extremely impressive. Joe should be thrilled when he sees it. One question, I'm assuming when you change tools in production, for two different kinds of cuts you would include that in the gcode. Assuming that it's running, makes it's passes, pulls back to the tool dock and shuts off before or during. But how does your router know when the spindle on your hitachi has fully stopped before it can release that bit and grab a new one or do you just set a certain amount of time? Thanks!

Router shuts off befor pulling back.
Video will show this.

Had to break up video in sections.

Ok, I am VERY Imperseed, I love what you have done with the machine, from the drawer slides, cable carrier's, Tool Changer, and the top cover over bearings., you have to get me info on the tool changer... lol

This is what I love about this community, people taking things and helping others, and improving the DIY and allowing the average peoson to have so much fun.

You got to love it.

Wow thanks for the videos. What are you running for a controller and steppers? IPM? Nice work.

Great videos JLT, thanks for posting. If you want you can post more, I never get tired of these gizmo's at work.

Any issues with the length of the tool changer causing the router or gantry to shift during deep cuts?

I am really impressed with the ATC. I have the quick changer on my Sherline mill including the drill chuck and they are really well made. I believe you can get 1/2" shank adapter from High Tech Systems see here http://www.hightechsystemsllc.com/in...es/Page993.htm which I think should work okay with the Hitachi router.

JLT,

Thanks for the longer videos, that answered all my questions. Now I can add that toolchanger to my parts list!

You get my vote, for "Best CNC Machine" of the year!

Thanks for the info on the "1/2" shank adapter", I looked at that page, & didn't notice that 1/2” could be ordered.

Call if you need a 1/2” shank adapter instead of 3/8”.

I see that now. That would have saved me allot of time but I had fun making my own.

Xylotex
XS-3525/8S-3
3 DS/DS 269 oz.in. Steppers
24VDC 5.0A Power Supply
24VDC Fan

Rapids about 70 IPM but I rearly cut above 40 IPM.

This was built on a budget (Small one) so lead screws are all-thread from Tractor Supply, cheep (by the pound bolts) from TS etc.
Total cost with controller, old 266 computer. $900

Not so far but I don't take deep cuts.

How fast have you spun that tool changer. Seems a little large for 20,000+ rpm.

[David Da Costa]

I have been in communication with Derick at High Tech Systems and he confirms some of the possible dangers at spinning at such high speeds.

Here is what he says.

"The rapid changer is only guaranteed to 10,000rpm. The spring will will possibly come off after that speed. I have some heavy duty
springs that increase the pressure and should be able to hold up to the higher RPMs and horsepower. I have a 1/2" adapter for the Taig that screws on. You will need to take all responsibility for safety. I recommend a Plexiglass shield around the router in case something goes wrong.

I have been working on a ATC for the Rapid Changer for awhile now. I need to finish machining parts to see if it will work or need design changes. Goals have been durable, affordable, simple to use and require no outside electronics or air. I haven't reached all the goals yet."


His ATC that he is working on sounds very interesting.

I just got the same email, lol.

ATC photos.

[David Da Costa]

Very nice JLT

[JLT]

JLT, I think you forgot to attach the photo's

Don't know what happened. Had to edit.


More ATC photos.

Very clever using a ground down c-clip.
