💡 What factors actually matter most when sizing up a new CNC spindle motor?

- Cranking up kilowatt output gives you serious bite on thick stock but needs a slick water cooling loop to dump heat quick.

- Nailing down the exact taper size like BT40 keeps your cutters snug tight so you dodge wobble and wasted material, making tool swaps handy and fast.

- Swapping to a liquid chill system beats fan blew units because it pulls hot spots away from internal gears, which pays off big in reduced downtime.
