Get PriceEnd Mills speed and feed chart is listed below Since all speed and feed charts give a range for the speed to use, here are some general guidelines to help determine the proper speed to use Reminder: When using a carbide end mill, the cutting fluid must either be continuously flowing over the end mill or no cutting fluid should be used

Get PriceCutting generates a lot of heat, making oil based coolant preferable Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low If not using coolant, then max surface speed is 50 ft/min Insulation foam

Get PriceThe outside of the end mill/tire will be zipping past the surface below at 1,320 SFM (surface feet per minute) Okay, but how fast is the thing actually rotating, or its rpm (revolutions per minute)?
