Thread: Drilling large number of holes in 1.2mm stainless

Gday John - I reckon that would be perfect. How long would it take your machine to do that do you reckon?

P.S Stu - what I am making is a custom strainer to fit within a pot, John has kindly offered to assist with the machining of the bottom for the strainer. If I drilled my current pot it would indeed become a strainer but then I would need to make a bigger one to hold it! The concept is the same as using something like a pasta cooker like this...

..only the small size of the grain used in brewing means the holes in pasta pots are way too big.

Sorrry Brendan I've been partly missunderstanding what you were trying to do. I thought you had the two pots and were going to cut a hole in the bottom of the inner one to take your s/s with 200 holes in it. Thats why I thought Whitney punch would reach as the piece of s/s to take 200 holes wouldnt need to be very big.

There will be 133ish hole in the outside circle alone. Great job for a cnc punch press. Pitty I dont have access to one anymore.

I've never played with stainless steel so I'm not sure on speeds and feeds.

If flood coolant is a must, I'll need rig up pan/enclosure so I can use the coolant setup off my mill. This is a job I have on my to-do list anyway.

Once everything is all setup, its a good time for a cuppa while the job runs.
