Thread: Chinese Spindles
For that amount of money I'd want to be getting more than 12000rpm. 18000rpm would be much better, but it seems toolholders which are sufficiently well balanced for that speed are rare and expensive.
This lot look worth investigating:
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.
To Beat we have
12k rpm spindle cartridge
$1522 = £976.52

I asked her what spec were her spindles for $1920, and she has none left and it is only a guide price. and some of her spindles fall outside the top end as well..
But thanks anyhow JonathanAlways bear in mind that your own resolution to succeed is more important than any other - Abe Lincoln
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
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...
I was going by what you said here with regards to including a motor:
i'm going to have 2 pole 1.5hp 3 phase motors on mine, and i fancy drilling through the motor spindle and attaching the atc actuator on the top of the motor so everything is in line
