    Look for books in the audel's machinist series. I had one that explained metalwork with a cold chisel and files. I can't find it now but I bought a bunch of paperbacks in this series for around $7...

    This is the autotransformer I used for my install. I paid around $250 from a local electrical supply house. I've seen lower prices online but shipping is expensive on these:

    Cleetis,

    I'd recommend opening up your search to regular robodrills as well. I recently bought and setup a T21iFL in my small shop and am extremely happy with it. I decided the autolube system...

    The approach I take is to determine what range of clearances are acceptable and in what directions. Is the nut located to the shaft by the thread OD or is there a pilot on the nut that engages...

    Do you have space on your fixture to mill a c-bore over the threaded hole, then slot the c-bore somewhere to let the disk flush out while drilling?

    One other thought is a stepped drill. the...

    Update:
    I tried out the helical 1/2" Dia, 3" reach, 5 flute high feed rougher in my 10k dual contact robodrill cutting normalized 4140.
    I had very good results roughing a part out with the...

    Thanks for the feedback. I don't generally have a lot of deep roughing but often enough that I've fought with chatter and poor tool life using long roughers on my old machine. I also had great...
  15. High Feed roughing on dual contact 30 taper

    I'm going to be cutting some 4140 steel fixtures on my dual contact 10k robodrill and need to reach about 2.8" deep with a 1/2" diameter endmill for a good bit of the cutting. I thought this would be...

    I drilled several hundred steel grade 8.8 bolts and found the thread rolling and head forging made for a huge variation in toughness along the depth. I would guess 18-8 will be similar. Your drill...

    Thanks for the info. I have a vacuum pump I'm going to try, as my spindle purge pressure is only 10-13psi. This points to the thought that a 1/3 hp pump can keep up continuously in place of a several...

    Thanks for posting your wrap up on connecting to the control over ethernet. I'm about to start down the same road with a 31i-A5 robodrill and have a few clarification questions for you.

    Aaron,
    Can you provide a manufacturer and model for the rotary vane pump you use? I'm interested to see what I can find in that realm. I got a refrigerated air dryer anticipating this purge flow...

    I completely agree that a low end compressor wouldn't last long running continuously at 125psi, I was wondering how long one would last if kept at around 50 psi and maybe add a small cooling fan.

  22. Spindle purge air - dedicated small compressor

    Im setting up my new to me robodrill and was wondering if anyone has set up a small 1hp quiet compressor to provide spindle purge air at the 50-70psi required at the machine.

    My thought is that...
