Router bit recommendation, spindle speed and feed rate?

Hi,
Thank you for all this info!

We are cutting 6.5mm and 9mm Birch plywood, ideally cutting right through within 2/3 passes. (ie 3mm per pass maybe?)
We have a large side channel blower (vac pump) connected to a pipe distro system under the table, which then feeds into 5 vacuum zones. We have ultralight 25mm MDF (plained on both sides) spoil board, so vacuum old down is covered!

We are meant to have this spindle .. http://www.marchantdice.com/worldofcnc/pdf/ELTE.pdf .. The 1.1kw version.
The inverter runs it at 3 phase I believe.
We were assured it was more than suitable for the requirements we have, and that they have clients cutting though 21mm ply. We have run a few tests on 6.5mm ply and it does work quite nicely, just looking to optimise it now..

However we think they've installed a different spindle to what we are meant to have! We think we have this .. http://www.worldofcnc.com/milling-sp...or-p-2671.html

Once we've straightened out the spindle clarification we should have a machine that can run upto 24000 rpm and a max feedrate of around 5800 mm/min.

I hope that clarifies our situation!

Cheers James

Hi James,

Can the machine cut at 5,800 feed or is that just rapid speed? There's a big difference.! I would would expect with it being R&P that would be cutting feed.?

Hi,

Had some major progress this afternoon, using a single flute up cut bit (5mm wide).
With spindle at max (18000 rpm we think) we tested cutting through the plywood at 3mm and 5mm depths, then tested speeds from 1200 mm/m upto 5000 mm/m.
All speeds gave good results, however over 2000 mm/m it was fantastic! Beautifully clean finish.
More tests to be done this week, also need to get the spindle issue sorted! Ie the one we paid for!

Will keep you updated!

Thank you.
