Just Asking... Tooling and mill sizes for cnc

Postby NwBie67 » Fri Apr 10, 2015 7:42 pm

Hello
Yesterday, I went to a machine shop to buy and end mill but with many of the piled up together, I got confused and didn’t know which to pick. I couldn’t take the risk of picking a trial mill. Even though they all looked okay, I knew there must be a slight variation between size, performance and cutting parameters. I need some good advice from a concerned fella to help me identify proper micro end mill geometry.

IDK if this helps, but did you get your machine yet?

It depends on what you will use the end mill for, silly. The first thing to ask is if the diameter of the tool should be big so that the tool is rigid or smaller in order to optimize waste. Wouldn’t want more shavings then piece in the end. Then you need to look at the material you are cutting. 1-2 toothed mills are great for alu and plastic but suck for harder metals. (This is why it is important to know what you use the end mill for) and finally the surface treatment or the material that the actual tool is made from. a hard outer coating coupled with the right cooling fluid is essential to assure precision is kept.. Anyway hope this helps a little
