Yeah quite large, spindle is 100mm and the harmonic drive for the 4th ways 16-17 pounds alone.
It’s definitely a beefy set up.
Bt30 is more because I want to use slitting saws, tapping heads, and all the other cool tools that bt30 provides. Less because I need it for rigidity.
The head is really more iso30 because it doesn’t have the drive dogs but I say bt30 because of the tooling I’m using and it’s not rated for high speed like iso is.
Small updates, waiting on belts to arrive and then I’ll upload more pictures. Finished stand offs, installed more electrical stuff. Added all the plugs for additional components and now I need to build the way the wires come in and out of the box.
Your harmonic drive looks huge. Here’s a post from a Tormach group on FB that I saved, because really like how this guy approached making new enclosure/base for the harmonic drive. I’m actually planning on going the same route once I finally upgrade the controller. Maybe you’ll find this useful as well.
I’ll just upload the pictures from that post then. OP bought used microarc (torchmach’s 4th axis) which arrived in a damaged box and scratched up enclosure. He purchased this block of aluminum from McMastercarr. All the sides were already machined square.
Thanks for posting the photos as I don’t have facebook access during the week and probably would have never seen that beautiful setup. He needs to add a power winch to the side with a pulley system for easy mounting dismounting.
I saw someone do it on their machine and it was very clever use of a harbor freight $60.00 winch that made the task very easy and allowed full table access when needed.
Well everything’s in(except air solenoid bank) and all the servos work.
Wireless Probe turn on works, which is super cool.(this means when I put a probing routine in a program, the tool will get called up. The machine will turn on the probe and then probe and turn off.) just wild to see
Need to add all the wire pass throughs on the bottom as well as add inputs plugs for homing switches(I’m using the stock HDM switches so this will come last probably)
Working on z axis this week, machining all the lathe turned parts this week and next, I can finally see the end of the tunnel though.
Once servos are on, tuning will need to take place and setting up of the inputs for centroid.
yeah it’ll be dancing around for a bit I’m sure, but in my plans, I’m going to anchor the HDM and pour a concrete epoxy base in its enclosure. Because why not.
