Chinese Spindles

[Ricardoco]

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.

I'm not sure what you mean? The price they have quoted is well within the price range on all Ms Xing's listings.

The 1530-9-12 as it is 9-12krpm looks much more suitable for your application.

is new unlike some of the links you have provided

Which?

It is like those hotel rooms starting at £19 when you get there they are all booked out, Every time..

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..

The 1530-9-12 as it is 9-12krpm looks much more suitable for your application..

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.

Which?

take a look at the pictures you cant miss it.. when i asked her if they were "used" she just said "some" Its all too easy to blag and blame the language barrier when in fact every word is understood perfectly..

But thanks anyhow Jonathan
