ISO 30 Spindle

[wildcat]

Anyone else see the following? What is your opinion on replacing the R8 spindle with this one?

Tooling is expensive, R8 can handle 2 or 3 horse power OK. So the only real use is if you are going for an ATC.

I speced my manual RF40 with an ISO30. I wish I hadn't. Thought I was being clever. Ya well.

I haven't brought any tooling yet and it said while supplies last so I ordered it already .

I'm probably not going to do an ATC but I plan on using more the one endmill when I'm cncing. So this and a power drawbar would make changes very quick.

There are ways of achieving quick change tooling with an R8. Have you priced an ISO30 endmill holder. ISO30 has come down in price in recent years, but still I think it is more expensive and hard to find.

What did you pay for the spindle.

i bought my ISO 30 spindle as well. it was only $65, and they should fit all the square column mills. i am waiting for aaron to release the torque procedure for the angular contact bearings, for the spindle, as well as the belt drive setup to all me to run up to 4500 RPM.

then i plan on building and ATC. this iso spindle will be pretty slick, i can't wait to get it assembled.

The spindle is $65 and in the kbc catalog the holders are between $95-$105 for collis and $35-$43 for the kbc ones.

Did you speak to Aaron about this, did he give you idea of when and how he's going to do this? Thanks.

[philbur]

$65, is that for a complete spindle assembly, including bearings, or just the "central" spindle shaft.

Looks to me like you should evaluate the price for alternative quick change systems, including tooling, before you make the switch to ISO 30.

Am I missing something? Sixty-five dollars for an industrial quality spindle? Add two bearings and a little work and you've got a first-class tool change system. The last time I checked, tool holders were available for $30 on up to over $100. Compare the quality of the spindle that Aaron is offering to the hobby-class R8 quick-change systems others are offering. Compare the size of the tools that can be used with the various systems. I'm just not aware of a 'downside'. It seems to me that if R8 is good enough, then all of us who own an IH mill already have that. For those of us who would prefer a heavy-duty quick change system so that we can pre-set tool lengths and change tools in a matter of seconds, then Aaron's system would be a perfect match. The other 'systems' on the market look light-weight to me, better suited to light cuts and smaller tooling.

I bought one. I expect the NMTB 30 will be a bit more rigid, and the idea of a toolchanger is nice, but the main reason is I want to build a belt drive without taking the gear head out of service. At the rate I complete my projects, I would get the gear head disassembled, need to do more milling and change the design, and just get stuck for years. Building a simpler head around this spindle, I can have a working mill at all times to facilitate.

I'm going to set it up to take the larger sized motor right out of the box without having to turn the shaft down. I'll probably just build it so I can bolt it up to the column in place of the existing IH head. I'm expecting to build it out of 1" aluminum plate so I don't have to worry about the metal warping at all. Should be a fun project. I will eliminate the quill as well, to wind up with a CNC-only head.

Best,

What does the ISO 30 give you:

1) A tooling system designed for 5 to 10 hp on a 2 hp machine.
2) Additional rigidity. Have you concluded that the mill is rigid enough to benefit from IOS 30. R8 is good enough for a Bridgeport.
3) A quick change system. Not until you add a powered draw bar. But then you could add a powered draw bar to your current R8 system.
4) Repeatable Z axis location for pre-set tool locations Don't you have this with R8 tooling, the taper angles are similar. Agreed not with and R8 collet style quick change, but then you don't have the possibility of even using collets with an ISO 30 in the first place, or do you.

Will a light weight mill like a 2hp square column bench mill really benefit from ISO 30, why not ISO 50, or are you better off spending your time, money and energy elsewhere.

Just some questions from a novice trying to understand, so please correct my understanding, don't roast me.
