What's the best way to cut the following hole with a non-CNC Grizzly X3?
- Material: 6061-T6
- 2.5" diameter
- 1.5" deep
- Semi-circle "pillow block" (see picture below)
- Tolerance: +/- 0.05"
- Qty. 6
Do I need a boring head setup for this, or is there a quicker/easier way? I've never bored anything and actually I'm still a little confused on how I would actually use it and how long it would take to achieve a 2.5" hole.. For example, do I start with the largest hole I can drill (e.g. 1" dia.) and then incrementally bore 5 thou at a time until it's 2.5", or can you just start with the boring head at 2.5" and just start cutting? Also if a boring head is the way to go, would a 2" boring head cut a 2.5" hole, or would I need a 3"?
Life would certainly be a lot easier if I could do some circular pocketing but I'm months away from even starting the CNC conversion Anyway any help would be appreciated.
