Running CNC Router at 25mtr/minute

Or you could use rotating nuts on a xx10 screw as the one you have

Anyway, what you are missing is that the company you are comparing to uses Servo motors, not steppers. you also do not state how heavy is your gantry. Also nowhere the acceleration is stated. And that could mean a lot. One thing is sure- you can not achieve real life cutting speed as this with stepper motors in any way and accuracy at the same time.

For your reference i move my 200kg gantry with acceleration 3000mms2 20m/min 2x400W AC servos 230V and 2 rotating ball nuts on 2510 screw. I can hit even 30m/min as my motors can spin faster than 3000rpm up to 5000. Your steppers are good to much lower speed , you probably need to drive them harder with better PSu at higher voltage and so on. So don't compare your machine with an overbuild commercial machine where they simply put some serious servos which are driven at 230V


PS. Machining at high speeds especially more than 10m/min and Hi Speed toolpaths makes that nuts and screw heat very seriously. You must make sure all is perfectly clean and greased properly
