By the way, I made a similar storage thing for ER 16 collets last
night. This time I bored each hole with a small end mill, like Jon
suggested. It worked like a charm, actually a very fast and gentle
process. No mess with stringy chips. Just 12 minutes machining time.

It was a grid of 0.64" ID holes, 3 by 5 holes, for the total of 15
holes.

Here's the code:


O100 sub
#xc = #1
#yc = #2
#safez = #3

#milld = 0.2310
#frate = 10
#diameter = 0.64

Ocirculargroove call [#xc] [#yc] [#safez] [-1/8-0.02] [#diameter/2] [#milld] [#frate]
O100 endsub

S1 M3 M8

Oapply_to_a_grid call [0.5] [0.5] [0.9] [0.9] [5] [3] [0.02] [100]
