Dialing in the SainSmart Genmitsu 3018 PROVer

Two things set the numbers on the SainSmart Genmitsu 3018 PROVer: how fast the 775 Motor Spindle spins, and how much the frame can take without chattering. It runs a working range of about ~5,000 to 10,000 RPM, on lead screw. The SainSmart Genmitsu 3018 PROVer has a lighter frame, so shallow passes and patience beat trying to hog material in one go.

So for a 1/4" two-flute bit in softwood, a sensible starting point on the SainSmart Genmitsu 3018 PROVer is around 10,000 RPM and 60 inches per minute, taking about 0.06875" per pass on a slot. The full chart below covers the materials you are most likely to cut. These are conservative starting points: always test on scrap and let your ears do the final tuning.

SainSmart Genmitsu 3018 PROVer feeds and speeds FAQ

What RPM should I run on a SainSmart Genmitsu 3018 PROVer?

For most wood with a 1/4" two-flute bit, 10,000 RPM is a good starting point on the SainSmart Genmitsu 3018 PROVer. Its working range is about ~5,000 to 10,000 RPM. Go higher for smaller bits and finer detail, lower for big bits and heavy stock removal.

What feed rate should I use on a SainSmart Genmitsu 3018 PROVer in hardwood?

Start around 50 inches per minute with a 1/4" two-flute bit in oak or maple on the SainSmart Genmitsu 3018 PROVer, at roughly 10,000 RPM. Listen to the cut and adjust: clean chips mean you are dialed in, fine dust means you are going too slow.

Can a SainSmart Genmitsu 3018 PROVer cut aluminum?

Aluminum is a stretch for the SainSmart Genmitsu 3018 PROVer. Its frame is on the lighter side, so if you try it, use a single-flute bit, very shallow passes, lots of lubricant, and low expectations. It is happiest in wood and plastics.
