Yep thats exactly what I want it for my next machine.!! It will be VMC or possibly HMC which is the latest train of thought.!! Either way it will be massive strong.!! (For DIY)Quote:

Still need more motors and few other bits but I'm getting there slowly. just keep watching for the bargains and trying to snag them before some "OLD BASTARD" does. .:whistle: nearly snagged my self a pallet loader and tombstone other day but didn't happen. . :grumpy:.!!! That would have decided it was HMC which I'm sure it will end up being anyway.?
Dont see many spindles comming up for sale thou and have thought about buying S/H biesse type machine but not really what I'm after. Plus not seen anycheap enough to make stripping out worth it.!! Thou you never know one could pop along unexpected, but I bet you £1000000000000 it does so when I'm brassik or tax mans raped me again. .!!!!
Why they only go backwards.:whistle: . . . . . . . . Even Lewis whinged about it off start at weekend.! . . . . Anyway I've got a spare motoX gearbox that can just about handle 20K if your stuck. LolQuote:

DMM you can have a full 4 axis set 1000W motors and drives BOB, PSU,cables etc for $1600.!!. . .Not exactly comparing apples with apples due to lower RPM but still good price.Quote:

Yep you are right and with free shipping thats a real good deal... Im still trying to find a low profile motor with enough power to gear up and down around 6k and im not having any luck.. it looks like im going to get my atc but i will onle be able to draw pictures with the machine.... in ten colours of course..Quote:

all the screens and guards have been ommited for clarity, the shelf will have doors on it and the tool rack will actually be behind a guard that moves when neededQuote:

Ok Just had an update and i think we are getting a little closer...
" Hi Rick Pls check the attached, my quotation as below,
SPP1030-10-17F: FOB Dongguan US$1,142.00 in each.
Its max revolution is 10,000rpm, but if you insist 12,000rpm, price will be US$1,586.00, as we need to adopt Germany ceramics bearings, its cost is much higher than our standard bearings (NSK brand, made in Japan)
Any question, pls let me know.
Regards Sam
Ive Now asked for shipping and unit discount for 5..
so fingers crossed ...
Attachment 6180
Okay update:- $1522.00 each if 5 units ordered, awaiting shipping costs now..Quote:

This lot look worth investigating:

http://www.alibaba.com/product-gs/36...dle_Motor.html
In particular the first one - 1130-24Z or 1130-16Z. The 24Z (24krpm) has 35mm bore bearings, but the 16Z (18krpm) has 40mm bore thin section bearings. Need to investigate which is strongest. The one you have a quote for uses 45mm bore bearings, so it would be more rigid, but any of these will be more than the standard 2.2kw ER20 spindles which only use 25mm bearings. If they can't wind the -24Z for 220V then it'll have to be the 16Z spindle anyway.

First of all i dont really need 18k and None of the links you put on there are quotes, but just guide prices, get some quotes and see what you get, the item i have posted is without motor, i am awaiting updated paperwork for that, and is new unlike some of the links you have provided, they are used/refurbished items and as such very overpriced, i want BT30 ATC 12k rpm max (just for flexability) so if you can go cheaper price new not used, then post the quotes and i will contact them and may even buy one..or moreQuote:

As i stated earlier in the thread i want as much flexability as possible which meant buying a seperate motor, 9k is to high for the lower limit. As you stated earlier the motors have no power at the lower speed, I will be gearing down to 2k on spindle with an approx 0-6k motor and up to 10k if need be i will be using pulleys for this, with a little left in reserve.Quote:

I've had a thought. We discounted making these spindles as it would be too much hassle making a one off. But i want two, and overall we're looking at five so maybe we can get this sorted and get 5 universal bt30 spindle sections made, and configure the case and bearings to suit our own requirements. This way we all get what we want and the expensive ground spindle can be made for us.
anybody else want to jump on
Well I'm willing to explore that avenue, whatever gets me the ATC spindle i require..Quote:

The other problem is the cost of the super-precision bearings which are a necessity for the sorts of speeds we're after. The place I posted in post #101 may help there.
I bought plenty of 35mm EN19 steel for precisely this project...
9k is almost certainly not the lower limit, I bet it is 9k upper limit with 'standard' bearings and 12k upper limit with the better ones.Quote:

The design of this spindle will probably be longer that the design on other ones, so mine may well be a special.
:dejection:Back to the trawling then....:sorrow::sorrow::sorrow: HELLLLPPPP Im going round in circles here...lol
no reason why we can't keep going down this line, it just means my ones will be slightly different
im sure we will get there, as i said i can wait for the best solution anyhow..Quote:

Did you get anywhere with this?Quote:

'Fast delivery and nice spindle, but not the dimensions shown on the drawing on the listing. Diameter is 80mm above the flange and 85mm below it. It is in fact a SIPU model SPP8030-060-10F But still a BT30 ATC and 6000rpm so I am happy. :) FYI the timing pulley is a 45 tooth HTD5M and is 35mm wide Thanks'
Still too much to spend for me to only get 6000rpm...
got the spindles back from the grinder and a bt30 hoder rings quite well into them. I'm in two minds now whether to leave the motor/pulley arrangement as is (bridgeport), or remove the pulley section and mount the motor directly on top of the spindle with a drawbar through the motor.
Well I got there in the end but via a different route. I ended up buying two HSD router spindles which have a 30 taper and air powered atc. They are 6.8kw and 24000 rpm, and should have a fair bit of power run at slower speeds.
Both of these I presume?
