Hi,

I have a jcut 6090a equiped with a 1.5kw spindle / vfd, er11 collect. The machine runs fine since I've bought it 2.5 years ago, but I need larger tools : I cut wood and the surface quality when profiling is not good with 6mm bits and 3d surfaces takes too long. Larger tools may help.

What do you think of that spindle : Professional High Quality CNC spindle motor. ? This comes with an er20 collet, great for 12mm bits !

Do I need to upgrade my VFD ? I don't need the full power of the 2.2kw spindle...

Thanks.
