Machining aluminum drag chain support arms to test recent ATC CNC modifications

- I am finally ready to see how my new CNC ATC modifications will function together.
I am testing Masso's new 5.100b Beta software, my new floating dust shoe design, and linear tool rack with my (modified) Onefinity X50 Woodworker CNC router and Jian-ken JGL ATC spindle.
The video slideshow includes machining clips of the aluminum support arms, as well as details on the CAM parameters for each of the toolpaths.
For those considering the use of MIC-6 tooling plate there is something you should know. It is CAST aluminum that is Blanchard ground. It is not guaranteed to be flat. It is also not a good choice for structural components that could experience side load against its original thickness, for it is porous and can break (I've had it happen). It is well suited for light duty applications.
All good points. I knew this going into the project, but for me availability, cost, and concerns regarding the ability to machine large flat surfaces were factors. The quoted tolerances in general, and of my selected pieces specifically, were acceptable. I think if I had a larger, more rigid CNC, I would have tried to source thicker plate. With this new Z assembly, I will see if I can get good results facing large rolled aluminum stock with better than cast tolerances. If so, and if my current assembly does not perform as expected, I may machine the plates again but with 6061/7075/etc... Thank you for sharing your insights.
thanks for the video. if you don't mind me asking, what brand spindle are you using. in the process of finishing my cnc router and looking for a decent atc spindle. thanks again.
Happy to share. I purchased my spindle from Jianken. It is a JGL 80 mm 2.2Kw water cooled. So far it has been working well, and the before and after sales support, along with payment and shipping were all positive experiences. A number of others in the forums I frequent have also had similar experiences, some purchasing the 100 or 110 mm versions.
Dude, is that a vacuum cover around your spindle head??? had to respond before I watch the rest of the video😅
It is part of the design I am testing. The main aluminum dust shoe has a 90 mm diameter thru hole for the spindle. I am experimenting with attachments for the top. This clear acrylic tube extension is one I really like, as it allows 'some' viewing of the machining from above. I am still deciding on its final height, but this one, along with the bristle ring attachment on the spindle end, catches almost all chips.
@@tmtoronto3741 dude it’s genius. Can’t wait to see your attachments.. I’m sure there are others that would love to have something like this
@@anthonyrivers8395 thank you. If interested, this is the link to my previous video, where I detail the making and functioning of the floating dust shoe - ua-cam.com/video/s_ItrmraiKE/v-deo.html
