Video: High Speed Milling—900 ipm
Demonstation illustrates the kind of metal removal rate that is possible in aluminum at dynamically stable speeds.
Hard milling allows mold components to be machined in the hardened state, thus skipping several expensive and time-consuming processes such as electrical discharge machining and hand polishing.
If you want to use a high speed milling spindle to machine aggressively, then information about chatter should be more than just background noise. Here are some basics.
Different machines offer different approaches to rotary travel, and each design has its own strengths. Here's how they compare.
