Well it's pretty much done (again lol) I changed out the roller chain with CRP rack and pinion drives. I also change to THK SHS20 and 25mm rails and bearings. The. Machine runs very smooth. I'm getting right around 780 IPM with the 3:1 reduction, I'm running the machine with a G540. The only thing to do now is put the controller and PC in one box and mount to side of machine. What do you think.

Nice build

Famous last words! The only thing left to do, is a fill-in-the-blank statement with home built machines. Looking good so far though! Is the speed you are getting recorded from just jogging the machine around, or have you had it actually doing some cutting through Oak, or other hard materials at that speed?

[mike2768]

So the speed is just jogging the machine when setting it up. As for cutting speeds I will be do some testing very soon.

Well I made my first part with the rebuilt machine, I must say it came out awesome. The machine still needs some setting tweaked but other then that its great. There's two pictures, one of the part and one of what the machine looks like finished.

What feed rate did you cut that "First Part" at? Looks great!

The feed rate was I believe only set at 50ipm it could have handle higher. I really like the way Delrin plastic machine.

but you probably dont like the smell

[mike2768]

but you probably dont like the smell

I don't really get any smell from the plastic, I think the trick is not to cut at high spindle speed with slow feed rate

[mike2768]

I've been using my machine for a little while now and very please. Now it's time to true the thk rails I have on the machine. What I mean is to make sure they are parallel on the 8020 I'm using. I cut a small bracket to make sure they are, check it out.

Very nice, I like that the gantry moves is the Y. That is something to keep in my memory for the future.

[Master of nun]

finished!


It won't be long and you'll want tool length sensing, dust shoe with extraction, 4th axis, vacuum hold down......



Looks great all the same, that part does look awsome

[mike2768]

Yeah what was I thinking, they're never really done are they. I'm still looking for ways to make it a better machine 😃

[mike2768]

I've been busy lately. I had a little time in the shop today. I cut out a aluminum sprocket. It turned out awesome. What do you think.

[CarveOne]

Yes, awesome it is. Nice work.

[mike2768]

Yes, awesome it is. Nice work.

Thanks, I'm happy with the edge finish to. Time to put this machine to work and make some $$$.

[mike2768]

Here's a few videos of the sprocket being cut. I hope this works.

How do I put a direct YouTube link in a post, I forgot :-(

[LeeWay]

Copy the address bar in Youtube and paste it in your message. The software takes care of the rest.
Great looking machine and work.
Keep it up.

[mike2768]

Here's the sprocket I made.
