Hi EddyCurrenet,

Very good of you to look into that for me mate I appreciate it. I think it is the way I will go perhaps something like this would do the job. http://www.ebay.co.uk/itm/2606245274...%3AMEBIDX%3AIT

I shall do my homework on them now to try and learn about them prior to buying one.

Many thanks

I've just had a quick look at a Chinese vdf manual and it looks like you can use a digital input to select different acceleration ramp speeds. So in theory you could have a switch somewhere that would select a slow ramp so that the vfd would slowly increase it's speed over time. Then you just switch it back to normal operation.

There is No need to warm up these spindles they don't use high precision bearings and there's enough tolerence for it not to be a problem.
I've never warmed my spindle up and it's been cutting aluminium for the last 3+yrs for 10+ hrs most days and bearings are still fine with no signs of wear.
