 How would one go about drilling multiple 12mm & 32mm holes (26 in all!)
on different axis using a machine?

The holes have to be accurate and are on different sides of the post
itself. Obviously, manually this is very time consuming, and ideas?

 A CNC with a 4th axis rotator will make short work of things. A two pass
drill fixture with the second pass indexed off the first will do for
smaller volumes. just use a tight fitting pin inserted in one of the
pass 1 holes to align for the second pass.

You've given way too little info for useful help.

What's the final application?

What kind of tools and machines do you have?

How much money are you willing to spend?

How many posts do you have to produce per batch, per year?

Anything else you can think of.

Regards,

Robin

Final application is to mount two brackets on either side so accuracy
is vital

Currently no tools nor machines - costs is not a problem, it's a
expansion job for our company so we are currently looking into ideas to
this problem

10,000 Alu tubes a year
