I am looking for a new spindle motor . I was hoping to find a 3.7kw (5.5kw peak) but the issue is getting a frame size to fit at a cost that is sensible . I have seen a szgh 2.2kw (3.7kw peak) that would be easy to fit and use . Question is how much difference will it make . Its a machine for fun , not production . Plus side on 2.2 is even better on a single phase service to manage . Most will be machining aluminum . Just not sure if the machine will be a dog or just a bit of feed rate adjust and carry on .

Thanks
Dave
