Feeds and speeds listed on this page have been tested to work with 2-flute, 1/8″ carbide end mills, the type of cutting tool that is most readily available in our store. Unless you're doing 3D contour cutting where the z-axis moves up and down a lot, we usually recommended lower plunge rates (100mm/min to 300mm/min) for most materials. ...

In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a "dropped" state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. 1. If the rotating speed is low, the ball in the ball mill ...

The simple guidance given for cutting steel with HSS was 100sfm at the largest diameter. Approximating pi allows the simple formula of 4 x cutting speed (sfm) / diameter (inches). For form cutters like your ball endmill, the recommendation was to cut that rpm in half. I think part of that guidance was to skew towards longer cutter life for a ...
