chipboard cutting with 35k-45k spindles

[Boyan Silyavski]

Is you're machine capable of cutting at 40m-50m/min? And holding parts down at those speeds? If not, the higher RPM will be of no benefit.

An 18,000 rpm spindle can easily cut at 30m/min with a 3 flute compression bit.

Exactly, thats what i meant. You said it better. But still 3kw more, according to my calculations will be aproximately 30% faster / or deeper/ so if in a production maybe its worth. But as you say, they will have to be able to hold it down properly, so its the setup... I believe these types of spindles are meant to go on machines that are able to auto feed the sheets and auto evacuate them from table to next stage. The whole chain of production must be fast
