Well today I placed a few orders...

The first I placed was for a stainless steel plate that will be taken to my water jet guy to be cut into watch case blanks so I only have to machine away a small ammount of steel.

The second order was for some more carbide endmills, I found a new place in Anaheim California that has a nice selection and a good prices. The fact that it's from Anaheim is only interesting to me because that's where Jarvi tool is located, they make the facetron faceting machine, one of which I own.

The third order I made was from sherline. I got some additional fixturing, a replacement way cover part, and the ridged column for the 2000 series mills.

And the fourth, and the one I'm perhaps most excited about, is the beall ER32 collet chuck. I really can't wait to try this thing out!

All of this and I'm almost as excited as when I ordered my sherlines, except with none of the apprehension.

Well I got the order from sherline and the steel plate is dropped off at the water jet place, the ridged column is fantastic, I can get my chip loads up where they need to be in steel to get my rpm and feeds up. I tried aluminum for the first time today as well, made me happy seeing a mountain of chips forming under the chipfall spewing out from the 5 flute 3/8ths cutter... all I can say is that I can't wait to get the M42 6 flute 3/8ths on this aluminum and use more of the available torque on my steppers with a higher feed rate; my spindle motor didn't even get warm... I'll take a picture of the machine when I get my ER32 chuck tomorrow.
I squared up a 2 inch aluminum bar on my lathe, then took the chuck off the lathe and moved it to my rotary table, then I ploughed through the material and brought everything sticking out past the jaws to exactly 34mm, the size of a watch dial I am making. I will be getting the drill bits required to finish the dials later this week, at which point I will take some pictures.

I'm going to get to play with anodizing these dials, making 5 of them, going to try different colors.

Well, some bad news. The beall chuck was kinda messed up, 7.5 thou runout in the taper... the tool has a severe wobble, not so much runout...

Two deep gouges about 90 degrees apart on the body, I guess something slipped during manufacturing...

The blanks are great.


And the C2 endmills are fantastic and cut through this 316 like butter.

So I thought I'd review these endmills a bit more.

They're made by YG and the ones I got are 3/8 x 3/8 LOC with a 0.01 radius and 1/8 x 3/8 LOC with a 0.005 radius.

The have several properties that make them very useful for someone with a micro machine that I thought would be worth mentioning.

Firstly, as someone who has a background in precision surfaces, these are a joy to look at. I can see my reflection in the carbide. And because of this, they run very very quiet compaired to most of the things I've put into this machine.

Alot of endmills I've tried to use produce so much chatter at the material removal rate my mini mill can support, they wear very fast and are generally unsuitable for stainless even though the endmill is made out of a material that will cut, and is rated for stainless.

I don't normally buy into manufacturer jargon but with these I think it's a worth mentioning, they attribute the reduced chatter to special flute geometry, I don't understand it, I don't really care right now. And the only reason I bought these was because they were actually cheaper than the ones I WAS buying...

I might spend the extra for the TiAlN coating next time.

Secondly these seem to flex less than other endmills I've bought of this same material, maybe it has something to do with that flute geometry. When I took a spring pass, it removed hairs of stainless instead of the smaller chips I normally see.

I'm becoming more and more prejudiced against any imported tooling, everything I've bought that's made here, even if it's cheaper, seems to be better.

Reading your review, it sounds like these are quality tools. So what's the name of your supplier in Anaheim ... and do they have a website? Thanks!

So unfortunately the Beall Chuck had 7 thousands of runout at the end of the inside taper.. more than my measuring tools would register at the tool... They issued a refund the same day though so props for customer service.
