Title: Scratch build Small mill
Post by: cnc dick on August 29, 2013, 05:43:44 PM

Here's a small milling machine I'm putting together hopefully it's a little more rigid than the standard X2(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7902_zps5f9f24ab.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7902_zps5f9f24ab.jpg.html)(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7896_zpsa6149625.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7896_zpsa6149625.jpg.html)(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7895_zps8afb902f.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7895_zps8afb902f.jpg.html)(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7901_zps12e91c75.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7901_zps12e91c75.jpg.html)

Can't tell from the photos, what size motor are you using to drive the Z axis? (From the looks of what you have so far, it's gonna need a hefty motor to lift all that weight without hesitation). Also, is that a draw bar spindle you have built? I'd like to see the specs on that, since I have considered doing something similar to my machine. What type of motor are you using to drive the spindle? Servo, stepper, or standard drill press variety? Looks like you've got a fairly hefty design so far!

The little mill is up and running I don't want to say finished because I don't think they ever are. Nothing pretty to look at but does a good job is a couple pictures(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7951_zps8db16451.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7951_zps8db16451.jpg.html) The picture of the chips shows good size and shape .060 doc 20 ipm 3000 RPM 5/16 end mill(http://i1333.photobucket.com/albums/w631/richard_nelson1/small%20milling%20machine/IMG_7948_zps65276bb0.jpg) (http://s1333.photobucket.com/user/richard_nelson1/media/small%20milling%20machine/IMG_7948_zps65276bb0.jpg.html)
