So been using my Lowriderv4 for a few weeks now and had pretty good success so far.
One thing I’m not 100% sure on though is regarding feeds and speeds.
When using calculators online anything but 1fluted 1/8in bits seem to demand feeds in excess of 3000mm/min (which is the max that I’ve been running). And at that point I’m still creating more dust than chips. For example for 1/4in single flute the f/s calculator recommended 4200mm/s at 17000rpm on the makita.
How do you guys deal with this? Do you just run it under the recommended feeds and live with the dust/increased tool heat & wear? Or do you guys run higher speeds at really small doc? Or turn the router down to minimum speed (even then it’s running slower than recommended settings).
This is the easiest thing to do. You can also try running a faster feedrate. Those calculators seem to mess up more than they help from what I can tell. Just look at your chips and go from there. If your making dust your turning the bit too fast or going too slow.
I am using bits from Sorotec, a german company for cnc stuff. They have a great calculator app for their bits. For a 1-flute 1/4in (6.35mm) bit I get 2200 mm/min @25k rpm for normal wood.
Basis for wood and that bit is a cutting speed of 500 m/min and a tooth feed of 0.0883 mm/tooth
The values for cutting speed and tooth feed are the ones that are dependent of the material. If you are lucky, the bit manufacturer has some values for those to start with and tune them to your material.
For me the feeds and speeds of the calculator app are working almost on first try.
