1.75 or 2.0 face mill, 11.1 inch reach, CAT40?
dstryr replied to Joe788's topic in Machining, Tools, Cutting & Probing
ugh. Only thing I buy from DGI is coolant btw. Tool Technology should have best sandvik pricing? -
How do you like the HEM500u? I was looking at them but wasn't impressed by the country of origin for the $$$$.
-
Yeah I have a torque wrench for it as well. For first ops it gets set to 45 ft lbs but for second ops I've gone as low as 8ft lbs to not colapse the thin wall parts. I was too cheap to buy one of their risers so I just built my own.
-
I love mine. Been finding a lot of uses for it. Repeats pretty well. Idk about .0005 like their spec though.
-
Machine the part from the back side. Cut the one wall with a keyway cutter. Flip over, relieve the one jaw so you can hold as deep as possible and not have to worry about that step. Piece of cake.
-
No. Mine are device parts....
-
How does holding it .100 deep in soft jaws work but holding it 1.150 deep not work? Show a picture of the part?
-
Okay so then you are stuck with rough / finish levels. 30-35* helix / 4 flute tool for aluminum will help as well. If it was me I would just finish the walls as I went down or ramp them with a 3/8 35* helix endmill.

I've been using them on some small 1x1x1 Peek medical parts. Holes down to .020 . .750 deep pocket with .040 corner radius. I do the best I can with the machine and send them off to them. Parts come perfect.
-
Good to hear. Hermle is top notch.
-
I use this place for deburring on parts where its a very deep cavity with small corner radius. They are very affordable, quick turn around. Not worth doing it in house. http://www.nitrofreeze.com/services/deburring/cryogenic-deburring/

You have to 2 op this part anyways right? Redo your process. Do the back side first / profile the outside. Flip it over, hold it 1.150 dp pocket (i.e. walls supported) in soft jaws and then do the inside pocket.
-
Mic6. I'd bolt it down and take a light cut on the plate.
-
What is your price range? I don't think that even came up.
-
Lots of knowledgeable people here .
-
My friend with a hermle says he can hold .0006 true position on his machine reliably. What does that C400 run?
-
Just switched all 12 machines in the shop to Qualichem coolant from blaser. No more stink, cheaper, and coolant washes off parts better....win,win,win.

Verticle mill opinions
dstryr replied to Prototype_guy's topic in Machining, Tools, Cutting & Probing
Out of that list the Okuma blows the machines out of the water...the only thing would be the control. If you want to do surfacing you are going to need the 31i control which I think is an expensive option on the DNM500. I have the oi DNM500 and its surfacing abilities leave a lot on the table compared to my Nh5000 fanuc 31i. A friend of mine surfaces aluminum @ 300-500ipm on his okuma and the surface finishes are amazing. -
You can get a Zeiss Duramax for the shop floor for like 50k last time I quoted one.
-
lol no way you are going to check TP of .001 on your HAAS with a renishaw probe.... Run the inspection program 5 times in a row and tell me if the results change due to thermal growth.

Manually hand wheeling on a fixed angle?
dstryr replied to civiceg's topic in Machining, Tools, Cutting & Probing
Yeah I'd probally mount a sub plate on the table and just cut a slot at the angle and use miteebites. -
Abbott workholding is where I got my 2 aluminum ones. Next time I'll just build my own.
-
Add a base plate and "machine" them to the same height. So the baseplate will be different thicknesses on all the machines but your Height from Center will always be the same? Seems like the quickest option...
-
This is where the GTO comes into play lol...let the tooling salesman fund the first run
