5 Best Milling Machines - Dec. 2021 - BestReviews

A good micro mill won't have the capacity of a workshop mill, but its feature set should be very similar. Power and speed. As we've already said, the forces generated by milling can be immense. As a result, powerful motors are needed. Motor power. For a mini mill, we wouldn't expect to see less than a one-horsepower motor.
