El Beast - Initial design phase, comments and critique welcomed!

[Zeeflyboy]

Slight tangent again but I just wanted to share this beautiful bit of kit that just landed on my doorstep...

I've been quite excited waiting for this to arrive:




It's a 3D touch probe called the TPA2 by Kurokesu... absolute piece of art! It's filled with di-electric oil (de-oxit I'm guessing) to prevent oxidation of the Tungsten carbide contacts which should keep it working reliably for a long time!

Looking forward to getting this up and running, if it works half as good as it looks it should bring a new level of accuracy to my work. I was waiting for this before kicking off any machining for "El Beast" so that I can use it to verify dimensions and for accurate two sided machining.


edit - got the concentricity at the tip dialled in to a consistent +/- 0.002mm so 0.004mm total.... just pushing hard on the spindle causes more variation than that on this machine so I think that is good enough for now!
