Making a DRO reader bracket for the mill's X-axis. This is a 3/16" 3 fl endmill, 1600 rpm, 5.4 IPM feedrate, and a 0.070" depth of cut. Little bit of chatter where it changes direction and bites into the largest amount of cutter engagement. 5/11/09.

Same DRO bracket. I'm using the Surfacing function from the Newfangled Solutions Mach3 Wizard to cut a little pocket to hold the DRO's read head. That's a 5/8" Iscar Helimill using APKT inserts. 1600 rpm, 20 IPM, and 0.070" depth of cut. The Helimill does a real nice job, and there's plenty of HP and rigidity in the IH mill to take good advantage of it. I'd like to try a 3/4 or even a 1" and see how it did. 5/11/09.

IH CNC Mill surfacing 6061 w/ 5/8" Helimill indexable endmill. 1600 rpm spindle, 10 IPM, 0.100" DOC. Gave a great surface finish!
