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...
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...
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...
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?
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? ...
You're the best, Craig. I'll ruminate, ponder, rest- and, hopefully, return with some useful questions.
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? ...
I understand that your efforts were rewarded with dissatisfaction. Other folks have surmounted the issues you've cautioned against, producing admirable results. I will scrutinize my results and...
@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...
While there has been some tertiary conversation about the performance of HDPE when milled that I've participated in, the primary thrust of this thread relates to success with long tooling. The...
I've sourced post-industrial regrind- it will provide a consistent material for testing. My candidate long reach tooling ranges from $250-$750 USD; I judge consultation a prudent preface- and far...
I can point to some general proscriptions gleaned from Google- https://www.boedeker.com/Technical-Resources/Technical-Library/Plastic-Annealing-Guidelines -but there's a good deal of ancillary...
A brief survey of plastic machining services shaping HDPE returned work in MUCH larger dimensions than I propose. Speaking to distortion, technique and capacity seems to be the determiner of...
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...
For those interested in reaching long into HDPE, I received some experienced feedback over at the Practical Machinist forum, here:
practical machinist (remove the space and stick in the "dot"...
Excellent references- the prices for 8" carbide at HTC are great! Much thanks!
Without doubt, HDPE has certain demands. My understanding is that string formation may be managed with proper feed and speed, cutting strategy, tooling, and adequate evacuation (air).

What's the longest stick out you've cut with? Into what material?
There's a great write up here: https://forum.avidcnc.com/t/vertical-workholding/34/11
I appreciate the threat of distortion. The HDPE billets themselves, at about 75lbs, will be annealed, spending almost 2 full days in oven between melt, soak, and cooling. The stock will be...
I aim to carve some large blocks of HDPE plastic, and am looking for tooling that can reach 7" or more. Are such tools available with a 1/2" shank? The intended AVID CNC employs a 4HP spindle...
I'm considering swapping out the 8" for 12" Z Axis on a Pro with 8" gantry clearance for sculpting HDPE elements positioned on a vertical table fixture. I was hoping for feedback from anyone who...
74 USD/25% off the vendor asking price. At this price point, I don't see cause for complaint- not from anyone actually wanting to buy. That said, you'll never be able to sell it- so, if that is...
I have misgivings about mating Avid aluminum extrusions to a steel table. Part of the draw of Avid is that it's not a big, impractical to move machine- something it also suffers for. I'm seeking...
Oh, ya- this thread is totally legit.
