chipboard cutting with 35k-45k spindles

[mintoska]

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.

1. Yes. Yaskawa servos 65m/min
2. Yes. 18,5kw vacuum
3. really? We have tested lot of bits. Max speed we have with 3flutes reached was 22m/min by non-laminated 18mm MDF board cutting ( Kyocera 12x22x75 S12x40 Z3 R ).
