[Leigh @ Kodiak]

[Joe788]

We bought that Okuma 5X.. it's got a 60 hp geared HSK 125 spindle.

I'd have rather had a Cat50 but that's what the machine came with.

The boss is going to gag when we start buying holders.

About all I can find are Sandvik Capto. Those are very nice... but also very expensive.

I spent some time looking for holders this afternoon and just about everybody tops out at HSK100

[Joe788]

Oh wow I didn't realize it was HSK-125. That thing is going to be such a monster.

Have you got a link?

Their online cataloge tops out at HSK100.

I found a couple of press releases stating they were offering HSK125 but havn't been able

to find any details

[Greg Williams]

Have you tried MST?

 

There is not much info on the BIG site about it as you said

I'd like to see one compared to a cat40 just to see the size difference.

[Greg Williams]

essentially HSK63 is the equal of CAT/BT40 and CAPTO C6

HSK100 is a similar size to CAT/BT50 and C10 so HSK125 is a bigger version with a 125mm face diameter

[silky_johnson]

Not sure if you got your answer, but the letter designation at the end of a HSK tool holder describes the taper configuration. I'm not sure the details, but an HSK#-A has a drive slot, and a HSK#-E does not. In your case of the difference between a HSK125 and a HSK125A.....I think your missing some information because there is always a letter at the end.

I stood in it today....

 

Haha. That big huh? The biggest machine I ran only had 100' of travel in X. It had full 5 axis capability on the head alone, then you could add a 6th to it with a rotary and it had two Gantry mills running on the same set of ways. They had another machine there you could make a semi on with the trailer attached! They would park the 40' Box truck on the C axis and spin it at 2 RPM during open house.

go here

http://www.sandvik.c...es/default.aspx (Sandvik Cad model download page)

and download this file

C6-390.410-125 120 ( a basic C6 Capto adapter)

These things are huge.. and expensive

[Parrish80]

You "should" be able to get HSK125's from any toolholder manufacturer.
They aren"t very common, which is why they aren't considered a catalog item.
But, that doesn't mean that they don't make them.

HTH

[EDDIE SMITH]

A SUFFIX AFTER THE NUMBER NORMALLY MEANS AN OVERSIZE FLANGE DIAMETER

 

DIN 69893-1 DOES GO UP TO HSK 160

So far I've found 2 off the shelf sources for HSK125

 

Sandvik makes HSK125 capto adapters from C4 through C10

Haimer makes some very nice facemill and ER25 and 32 collet checks.

Both of these companies have stock.

Bik Kaiser's Jpanese partner Big Daishowa has a limited selection of tools but they build to order only.

The do not maintain an inventory.

[Joe788]

So G, how much does a normal HSK-125, ER32 collet chuck cost?

This is the problem here. Some people forget to add the last letter, but according to the standard, developed here, all types are followed by a letter.

 

The thing is that the A standard is so common that people often forget to stress it.
