Cutting speeds and feeds for aluminum, brass, bronze, etc.
will be approximately the same as shown for cast iron.
The spindle speed for cutting soft and mild steel is
approximately 65% that of cast iron.
Hard steels and alloys are cut using spindle speed
approximately 20% less than shown for mild steels. Feeds
for cutting hard steels and alloys should be 50% less than
shown for mild steels.
As a general rule narrow cutter widths can be run at
faster feed/speed rates than the wider ones for each
Test your miller prior to placing it into production to
determine exact spindle speed and feed rate best suited
for your particular application. The above list is offered
merely as a guide for initial setup.
