The Heat produced while cutting depends on the friction. A second part is proportional to the volume of material that is removed. | |||
Half the milling depth, half the heating! 25% sidewards instead of 50% sidewards cutting=half the heating. | |||
Mill heads can break if the sidewards force is too large. So for tiny things, | |||
the feed rate together with the spindle speed and the cutting depth should be reduced. | |||
