I found a company in CT called Somma tool that still advertises QC30 tooling in their catalog. Leadtimes are between 1-3 weeks. Here is the link:

Somma Tool Company - N.M.T.B. Shank Collet Chucks

Figured I'd revive this old post in case anyone needs the info. I found a company in CT called Somma tool that still advertises QC30 tooling in their catalog. Leadtimes are between 1-3 weeks. Here...

35 HRc sound real hard for 17-4 condition A. That level hardness is usually acheived at an H1000 or H1050 condition. i would double check the material specs and make sure you know exactly what...

The general rule of thumb that I use is the drill size should be 1/64" smaller than the ream size for standard. For metric, I would guess 1/4(.010 inches) to 1/2(.020 inches) of a millimeter smaller...

You most likely work hardened the material. The only way to solve that is to take a large enough cut to cut under the hardened scale. As far as speeds and feeds go, your feedrate sounds good (maybe...

I did a job like that a few years back. I think it was a 1/32 dia. drill. TiAlN coated COBALT drill- not HSS, not carbide. Cobalt has just enough toughness to handle some abuse and is just hard...

Looking for a quote on two rods. The parts are identical save for the material - one is 6061 and the other is 300 series stainless. I'm not fussy about what type of 300 stainless is used. The...

No one cuts this stuff?

Really depends on what you're doing..material, size, tolerances, etc. For small diameter threads where hole depth isn't critical, nothing is faster than a tap-matic tapping head, especially when...

We use a substance called Rigidax for machining impeller blades. It very similar to a heavy duty wax. We simply heat it up, pour it into a mold and let it set. When your done, heat it up and melt...

My company cuts alot of 15-5PH in the H975 condition. Lately we have been toying with the idea of switching to Project 70 15-5PH which is supposedly a free machining version of the alloy. The...

Pure berylium is extremely rare. Don't confuse it with Berylium copper like most people do. I've machined both and they are completely different materials. In the US, it is considered a strategic...

What is the radius of the tube/barstock? I would look into Laser engraving before commiting to build an EDM electrode.

Not sure where to post this but this seems as good a place as any. I also posted this in the Machine control section.
Can anyone recommend a good source for control retrofits on large machines? We...

Not sure where to post this but this seems as good a place as any. Can anyone recommend a good source for control retrofits on large machines? We have some old G&L machines - one 36" VTL and two...

416 isn't that bad to cut as far as stainless goes. I've never had it workharden (at least not like 304 or 316 will) Treat it like a piece of 4140 and you should be fine.

Never pre drill with an insert drill. They are made to self center and drill into solid material. I would give Ingersoll tools a try as well. We recently tested one vs a Seco drill in 304. The ...

Drilling? Milling? Turning? 13-8 should cut similar to 304....

I'm looking for a source for some high performance left hand taps. Thread sizes are 3/4-10, 1-8, & 1 1/8 - 7. Material is 15-5ph approx 38-42 rockwell. Pretty nasty stuff so I'm looking for...

So my question is what do you do about the floor thickness? Most home"workshops" only have a 4-6" thick slab. Did you re-pour or are you still on the same slab?

If you're going to spend 7k on a CAM package, I would spend extra 3-4k and get a seat of MasterCAM.

:cheers:

I've turnined it before. Really nasty stuff as I remember. Makes inconel look like 6061. It got so bad one time that some of the guys actually refused to run the parts and forced us to sub them...

Anyone have any experience with Kitamura's? I've heard that they are a pretty good machine. My company is looking at an older used one for prototyping and secondaries. Any suggestions or input?

It's comparable if not cheaper than a full blown CNC router. You get much finer detail than a router and they're pretty quick too. I was suprised when I saw one run. Like I said, it's a new...

I'd be curious to see what the winning bid is on this job. We're all so used to quoting hard stuff that no one wants to do, it would be interesting to see what a "cake" job would go for.

Just a...

Have you considered having them laser engraved/carved? I have a CO2 laser with a 12"x16" table that I'm trying to find work for. Sounds like it might fill your needs. I'd like to take a look at...

I would think it's pretty easy to spend 300K on a start up machine shop. A decent Vertical will run you about 60k. Then you have to tool it probably another 10-15k. A CNC lathe will run about the...

I'd typically try to program it out. You can either program the taper in or try changing your tool path to start cutting closer to the chuck and feed off on the free end. It could be that the shock...

What type of wood? I have a laser but I can only do 12"X16". Let me know if this would work for you...

Sent you a pm....
