Re: Cutting off on a hobby lathe

No you need an DGFH26-2 holder If you are looking for a 26mm blade.

Re: Cutting off on a hobby lathe

I use MGGN200 for aluminum, because there are easy to find positive ones... https://www.ebay.com/itm/166256238364?epid=16012269089&itmmeta=01J34SVMDB3SDPAXJJFEPHBHW2&hash=item26b5a4df1c:g:ShwAAOSwxOFaZmQZ&itmprp=enc%3AAQAJAAAAwHOa0yw1rDzVHCYVbuJiNLnuyu%2F9qhoHlZI%2F1WXliuRWv7E05lLTs92hSm...

Re: Cutting off on a hobby lathe

For aluminium use sharp positive inserts and no TIN coating, since Alu sticks to it.

Re: Slot Cutting Question

I thought from the pic it was 1/4".

For only clamping it at the ends, it must be stiff enough not to flex or vibrate.

YG1 endmills are top notch.

Re: Cutting off on a hobby lathe

Without pecking the first material would produce one very long curled chip per cut.

I hate to clean up those long curls :lol:

Re: Cutting off on a hobby lathe

Pecking helps to evacuate the chips, no problem with carbide tools. Milling or turning hex profiles is interrupted cutting...

Pecking is only starting a new cut like on any other cut the tool starts turning.

Re: Slot Cutting Question

Hi Richard,

do you have a picture of the 3 flute mill you are using?

Your cutting rate is very low, it should be no problem to go with 24 ipm.

The plate under the part is very thin, this would better work on a vacuum plate, or use something at least 3/4" thick.
