CNC Spindle choice and supply options - 2.2 kw water cooled spindle and VFD

[dogboy]

What sort of work are you going to be doing with your machine? Wood? Metal? - that governed my choice, there are various varieties out there: 2 pole/4 pole, constant torque & constant power, differing max rpm etc.

Thanks for your replies.

Initially, I mainly intend to be milling wood, but I have plans to do some Aluminium work and also maybe slate or marble (if possible)
Although, for wood I do not need the such spindle but I also want to use 1/2" cutters so need ER20 collets or larger.
Plus longer term, may also add some sort of flood / spray cooling when cutting larger metal jobs in Alu. but may also go further if my machine can handle it! or even upgrade some bits later.

I have the bed / stage XYZ all working and homing correctly now and only now need a spindle.

Thanks

Hi Paul, the 2.2kw would be fine for cutting all your types Wood Aluminium etc I have used it on all including sandstone and granite no problem but if you do get into stone, slate you will need to think of flood water coolant to the cutter or you are going to burn out the cutter quick.

On the first a larger cnc for cutting all stone/ granite many years ago we put a 4KW spindle which I got from Damon cnc in Germany a lot more money but that has been running I guess for 15 years 24/7 a lot of the time and I have changed a set of bearing in it.

Hi Paul,

So what did you go with and why? I am in the same situation, choosing between CNC4YOU and JAZZCNC.

Not entirely convinced if the CNC4YOU option justifies twice the JAZZCNC price for the seemingly same product.

If you're talking about the usual 2.2kW spindle + vfd + mount, they look like the same offering from China, but with different markups at each shop. Being how active Dean is here I suspect that you'd be able to discuss any issues directly with him, and it's cheaper.

Alternatively, you might be able to buy directly from China for less and get the same stuff, but import taxes, and the extra hassle if you have issues, along with the wait for delivery.... You pays your money and you takes your choice.
