kevinj308 Posted April 12, 2015 Author Share Posted April 12, 2015 I love that facing mill, shiny metal is just cool. Maritool 3.1 inch 6 insert. 4000rpm, .005 doc, 10ipm Link to comment Share on other sites More sharing options...
Toolguy Posted April 12, 2015 Share Posted April 12, 2015 You should be able to run 50 or 60 inches a minute on that cut. Link to comment Share on other sites More sharing options...
kevinj308 Posted April 12, 2015 Author Share Posted April 12, 2015 That's what my feed and speed software said too. It's pretty easy to stall out my spindle motor with that large of a tool though, just being super cautious until I get more time with it. Smelling the windings in my spindle motor as it stalls is kind of a bummer lol. Link to comment Share on other sites More sharing options...
kevinj308 Posted April 12, 2015 Author Share Posted April 12, 2015 (edited) Threadmilling is awesome! 1/4-20 thread test with a tool from Maritool. ETA Fusion360 made this super easy to do. Under the 2D drop down or the Drill drop down. Edited April 12, 2015 by kevinj308 Link to comment Share on other sites More sharing options...
Toolguy Posted April 12, 2015 Share Posted April 12, 2015 Yes - thread milling is awesome! Especially if you need to do a thread you don't have a tap or die for. Especially for blind holes. Especially for large sizes that you may not even be able to turn the tap without a 4 foot cheater bar. Especially for specials that there is no tap or die for. Especially for small holes you can't afford to break a tap off in. If you break a thread mill, you just dump it out and keep going. Especially...well you get the idea.

dskinsler83 Posted April 17, 2015 Share Posted April 17, 2015 So seems like my G0759 does not like to be used with a 2" face mill to tri top. Very crappy finish. Not impressed with the machine so far Link to comment Share on other sites More sharing options...
shutr Posted April 18, 2015 Share Posted April 18, 2015 Dan did you take any pictures? How much were you taking off per pass? Link to comment Share on other sites More sharing options...
dskinsler83 Posted April 18, 2015 Share Posted April 18, 2015 I took a .0036 pass to even up a slide that looked off a little and it left nothing but ripples that I blocked out with 320 and a piece of marble. then buffed, ran the cutter at 850ish and fed from right to left into the cutter rotating clockwise at a feed of around 15in per min Link to comment Share on other sites More sharing options...

It's tough to say without being there, but maybe double the rpm? Or more if you've got it. Does it max out at 2300rpm? Link to comment Share on other sites More sharing options...

kevinj308 Posted May 1, 2015 Author Share Posted May 1, 2015 Handles came out nice! Cut out my soft jaws for them, faced off the back side and bored some holes for pins. Getting close to making one for a keeper! Link to comment Share on other sites More sharing options...

kevinj308 Posted June 21, 2015 Author Share Posted June 21, 2015 Did a little engraving with F360. Was pretty easy once I figured it out. Insert a jpg of the image, use calibrate to fit the intended area, sketch the lines with tsplines, then trace under the 2d drop down in cam. Rotated the image a little too to better fit the target area. It wouldn't do the text with all the fonts on my pc for some reason. I googled that and its a known issue, but probably pretty low priority. So I had to use another cad program for the text. Link to comment Share on other sites More sharing options...

kevinj308 Posted June 21, 2015 Author Share Posted June 21, 2015 In a busy shop I could see having a separate machine just for engraving. The speeds and feeds are so slow it could tie up a more productive spindle for a long time. About 20min for the above, 2ipm @7k rpm. Then a clean up pass with the facing mill to take the burrs off. The engraving tool did leave quite a burr, Not sure if that's normal or I need to adjust something. Maybe just a dull tool. Link to comment Share on other sites More sharing options...

dskinsler83 Posted July 15, 2015 Share Posted July 15, 2015 Anything you'd change on your CNC mods? Is there a straight plug and play? Link to comment Share on other sites More sharing options...
kevinj308 Posted July 16, 2015 Author Share Posted July 16, 2015 Anything you'd change on your CNC mods? Is there a straight plug and play? The only thing I'd change is the Z stepper, I'd go to the next bigger one. Not a big deal, just wouldn't mind more z oomph. Plug and play I don't know, there wasn't when I was building mine. There might be now. Link to comment Share on other sites More sharing options...
