Mega Slow for doing what.? . . . . It's Milling machine not router. 4K is acceptable for Milling machine this size and strength.
If you have excess torque then with little ratio/belt jiggery pokery could soon increase that if required.

If your wanting speed to Cut aluminium then for the price of decent ATC spindle which fits this machine correctly and do it justice money would go long way towards building nice strong Fixed gantry machine with more cutting area that will chomp Ali equal to this mill.
