Machining stuff!

[gatch]

I dunno how much of the kb community are interested in messing around with lathes and mills etc, but I am I'm a machining apprentice and as such love seeing what I can do when I'm left to my own devices..

Seeing as how work is quiet at the moment and I have units to complete, I asked my boss if I could have a go at making some tooling. He said ok. So I did, I took the basic design from an existing 45 deg milling cutter and made a 30 deg tool for machining weld preps onto thick plate without having to mess around with packers and stops etc.

Made from a bit of P20 ( couldn't find any 4340 ), with 2 carbide tips at 30 deg from vertical, it even works, had it destroying a bit of mild @ 900rpm with a 6mm cut. Not bad for a first effort I thinks aye

900RPM is too slow........

I'd work on your photographical skills.

I concur, unfortunately our big TOS mill doesn't go much faster than that..

I'd work on your photographical skills.

I'd work on not being a homo, its a $20 web cam, that's as good as it gets.

looks like a pretty good tool, but the more important question is, how well did the battery machine stuff?

and yeh, 900 rpm is well slow for a carbide tipped cutter. We run a 32mm tipped facing cutter at 8000rpm and 2500mm/min (as fast as the fucker will go) decimates ally quite nicely.

cool man. i used to make smoking pipes in school metalwork

The battery needs regular grinding..

The shop I work in is mostly equipped with post world war machinery, if you mention high speed machining to anyone here they go arrrrrrrggggg WTF, VOODOO and BLACK MAGIC etc..

The only thing here that goes 8000 rpm is the die grinders..

edit - If you don't mind saying, who do you work for in palmy ? I'm serving my time at niven engineering down armstrong st.. (yes, those guys..)

I do a bit of part time stuff on the CNC mill (now thats real black majic!) at massey, cant say I've heard of niven engineering till now.

looks like you have made a nice job of it, make a couple more and sell them.
