Hey all, thought I would post my success, cut the sides of a bumper I’m building for the wife’s sled(snowmobile). Previous methods were plasma, then grind and finish everything. This one will get a light file/buff where need and straight to sandblast/powder coat. I have to say, this is why I bought this, and it performed as advertised.
Details: Inner details - 300mm/min federate, 0.5 pass depth. Outer details - F360 1900mm/min, 1mm cut depth. It worked on the outside cuts. I would recommend a shallower cut depth of the 0.5mm with the F360 1/4 end mill feedrate. But it all turned out awesome. No cutting fluid or lube. May make a drip line for cutting oil but it worked fine so it’s good for now. Cut time was about 6 hours.
Thank you for the suggestion, I’ll get my hands on a IV bag and give it a go. Also David, I used a 1/4" two flute end mill. up cut. Its made by Freud. Says its Industrial carbide. 20 bucks CAD where I live. My Router is a Mastercraft Maximum with my own lead screw Z Axis. I copied a members design so to speak, if you search mastercraft in the forums it comes up. However, I’m really looking at getting the M2 upgrade, my Z axis doesn’t seem to accurate because there is some play in the lead screw. It came from a trash compactor so, not really precision,
Edit: Forgot, I run the speed setting at about 4 for aluminium on the router, not wide open but close. Figured more RPM, smaller chips, not as hard on the cutter. Just a theory, probably got it backwards. LOL
