Mark,
These people make Femtosecond lasers for hole drilling.
There is an article about drilling holes in injector nozzles in
the current issue of Laser Focus World.
Here is a link to the company that sells the equipment. http://www.raydiance.com
hope this helps.

CAUTION do not try to turn a spindle motor rated at 12000 rpm at 24000 rpm!!!!!!!!!!!!!!
you will damage the bearings, the motor will over heat, the balance of the spindle will not handle 24000 rpm
and it could explode. THE MOTOR AND VFD MUST MATCH !!!!!!!!!!!!!!

Millertime,
check your Y axis limit switch it might have coolant in it or a loose wire.
I had this same condition about 3 weeks ago. had to replace the X axis
micro switch under the table.
Just a thought.

Try this.
you will need a .100 od brass tube, diamond lapping compound, one jack off drill chuck, model clay, and a bridgeport.
back up your glass with some tool steel so you don't break through.
chuck up the tube, build a moat around the drill location, fill moat with diamond compound and water.
start at 500 rpm
do not make heat
it will start slow until the diamond is embedded in the brass.
then "drill baby drill"
hope that helps.

James,
looks like you need to drop your start point 0.400
so if you started at 0.375 now you need to start at 0.775.
you have to match the pitch!!!

James,
lets say its a 1/4:20 thread, your pitch is 0.050
so drop your bottom start point in 0.050 increments from where you are now to get the depth you need.
use your cutter comp to sneak up on it.
