“Touch Probe” I think I made a good one
« on: August 02, 2007, 04:23:18 PM »
I had a problem using my tool height touch off and my probe
My height touch off was active low, a peace of urethane with a peace of aluminum glue to it.
But the probe was active high, to use both I had to go in to ports&pin and change it back and forth, not well
 
So I come up with this probe (active low)
It can repeat at .0006
Out of round .0009
For me, that good enough.
It can be made (active high) to, the over all length is 5” but I think I can cut that back to 4”
This was just the prototype, just two hours to make it and that’s with a design change in
Mid stream.

Good Job Gary,  ;)
     Are you going to sell any of these? Have you tested these? Does it work fine after thousands of contacts?

;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

It would be nice to sale some to get a little money back from my hobby.
But I will share the best I can; I just got an ideal and started making it,
All was done on my lathe using mach3turn and the wizards no cad.
I’ve tried to make a drawing so u can see how it’s made,
The body is made of Acetal rod and the ball is steel u need a spring at the switch holder and piston.
The switch is just a cheep radio shack, the next one I’ll get a better switch
I tested it 50 times with the mach3 plug-in “center of hole” it repeated the center by .0001
.0005 on one of the runs, if I turn the spindle 180 it was out by .0006 to.0009.
Sorry I’m not to good explaining it, but it dose work
Thanks Gary

I’m still tweaking it, the movement after the tip contacts and probe activates is
To long “switch adjustment” but don’t have time right now to get back on it.
It’s not ready to sale right now, but I will look at making some to sale when it’s ready.
Don’t know what the price will be, what do you think (not looking at coast to make)
But what the hobbyist could afford.
