This extreme flexibility enables a Munson® Pin Mill, with no modifications, to grind friable materials into tight size ranges from coarse particles down to powders of 400 mesh, and to de-lump agglomerated material. Materials remain cooler than in other types of mills since retention is minimal and air is

9-Twist RPM = 3200 x (12/9) x 60 = 256,000 RPM. Of course max velocity will be limited by case capacity and pressure. You can't switch to a slower twist-rate barrel and maintain RPM if you've already maxed out your MV. But the Miller Formula can help you select an optimal twist rate if you're thinking of running the same bullet in a ...

Theory. The drilling catalog or our experience tells us the cutting speed we need to use for a given application. On the other hand, the CNC machine is programmed with spindle speed. Therefore it is common that we need to compute the RPM from a given cutting speed either for programming or to ensure that the speed we want to run at is within the machine's limit.

You know how many revolutions the motor turns to make the blade complete 1 turn, and you know the length of the blade. With the motor rpm's you should have fpm then, I'm assuming it's governed around 3600 rpms. If you divide the number of wheel rotations by the number of motor rotations you'll have the final drive ratio.

End Mill Feeds and Speeds. The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed) and IPM (inches per minute or feed rate). We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
