  1. Re: ISO30 tool holder marks: is this normal?

    I applied a soft chemise and denatured alcohol to the holders- see attached images for the results on the two holders previously pictured. The chemise came away with lots of (presumably)...
  2. ISO30 tool holder marks: is this normal?

    I have no direct experience with ISO30 anything; mid-purchase of a used S30C spindle and tool holders, reported to have low hours. While inspecting the tool holders, all the tapers include...

    Much appreciated, and great pictures- thanks for making the effort. "I don't have a spin balancer so I'm relying on the existing set locations to get me close. So far no vibrations..." You...
  4. ISO30 Spindle > BT30 Tool Holder = Adapter Pullstud?

    I'm looking to use BT30 tool holders with an ISO30 spindle, was told this could be accomplished by replacing the tool holder pullstud. Machining the part is not in the cards- anybody know of a...

    Automated Screw Array Adjustment

    Wasn't sure where to put this. I'd like to use my gantry-style machine (AVID) to turn screws in an array, wondered if any here had tackled such a problem. For ease of fabrication, my preference...
  6. Re: Check out my progress on my tool carousel for my AvidCNC PRO60120 / CNCDepot S30C

    How has that S30C spindle performed for you over the years? What do you reckon was the highest load application you've performed with it?

    S30C Serice Life and Performance

    Looking for feedback from those who have put a lot of hours on their CNC Depot S30C spindle, preferably for regular production. What are you cutting, how aggressive, with what sort of duty cycle? ...
  8. Re: Welding Rotary Positioner as active 4th/indexed 5th axis?

    You're the best, Craig. I'll ruminate, ponder, rest- and, hopefully, return with some useful questions.
  9. Welding Rotary Positioner as active 4th/indexed 5th axis?

    Anybody heard of a welding positioner employed as active 4th axis table and manual or active 5th axis? It may be the tolerances and runout would preclude use- or maybe not. What do you say? ...

    Re: 3D deep carving plastic

    @metalmayhem, HSS might be an option, but have been cautioned against it with the purposed 7" stick out on 3/4" diameter by folks claiming experience with such long tooling into HDPE. I'd be happy to...

    Distorting parts is a possibility. What was the history of your stock? Was it annealed? What cooling did you employ? Was the tooling designed for plastic? Did your operations feature high feed...

    Re: 3D deep carving plastic
