1. A coffee grinding machine comprising:
a first grinder and a second grinder, wherein at least one of the first and second grinders is rotatable, wherein said grinders cooperate with each other so as to grind coffee beans, obtaining a first dose of ground coffee during a first grinding cycle;
a motor which rotates one of the grinders-relative to the other grinder at a speed of rotation;
processor circuitry which causes the coffee grinding machine to modify a grinding parameter for performing a second grinding cycle in which a second dose of ground coffee is obtained,
wherein said grinding parameter is modified depending on quantitative information received from an espresso coffee machine and based on a coffee preparation cycle performed by the espresso coffee machine with said first dose of ground coffee,
wherein said grinding parameter comprises the rotation speed, and
wherein said quantitative information comprises at least one of the following: a flow value of coffee dispensed from said espresso coffee machine and a brew ratio value.
