Tips for avoiding chatter

[helencmk]

Hi everyone,

I don't have this problem all the time but I'm just setting diamonds into rubover settings and the bur has chattered every time. I'm using a setting bur and a round bur on 18ct white gold. I'm using lube cut for lubrication and the shank is as far into the hand piece as it will go.

Any tips? Thanks in advance.

I should also mention, I have tried a combination of speeds and have tried the motor in reverse.

Did you try what many setters have used for years.... burrlife,wax candle,beeswax?

High speed ,lighter touch,finer burr ie more cutting edges MTC
And lube

I'm using Lube cut, the same as burrlife.

Possibly finer burr. It's just frustrating as it doesn't often happen with the burrs I usually use.

Maybe cutting too much metal with the setting burr. Did you expand the pilot hole with a bud burr.

I used a round to expand first.

Beeswax has actually made a big difference! Thank you. Usually only use that on my saw.

To avoid chatter keep your mouth closed. Also if there's chatter but everyone is wearing ear plugs is there a sound!

Try using a slower speed (lower RPM) or increase the feed (amount of pressure on burr).

It's the same principle as is used in a machine shop setting, just a different set of tools.

Just read to avoid chatter put the burr well into the flex shaft, more support, less exposed, means less chatter.

The flexshaft may also need lubrication. Also, make sure the flexshaft is fully snapped in the housing! Sounds like you are already doing these things.
