With micro-milling, tool size is relative to the application. Commonly, a 6-mm-diameter tool would be considered large and a 0.3-mm-diameter tool would be considered quite small. In this range, a spindle of 50K rpm would provide an adequate solution. Motorized spindles .

The difference between the volume of chips formed by "normal" milling operations and micro-milling can be as high as 9x for micro-milling and is typically on the order of 2-3x. Compounding the problem of higher cutting forces is that the micro-machining cutters themselves are small and less able to resist tool .
