Surface Grinder Coolant Nozzle

[Janderso]

I’ve seen these nozzles on Tom Lipton’s channel and Mr. Renzetti’s.
It’s my attempt to provide coolant where I need it without constantly fiddling with those plastic wobbly things.
The frame is easily adjustable vertically and horizontally.
The tubing is break line. Something I am very familiar with.

The original coolant nozzle for the Micromaster was a 1/2" diameter copper tube with a 90 degree bend, flattened down to perhaps 1/8" on the end, long enough to get quite close to the periphery of the wheel when it is at full diameter, it is fastened to the down pipe with a compression fitting. I personally do not think it is good to nozzle down coolant flow, as it tends to create more fine misting, not a good thing.

I like it! I need to do something better with mine.
Thanks Jeff.

Really.
Had I seen that on one of those fancy pants videos I would have made it that way.
The method you described is one hell of a lot easier than the contraption I made.

Oh well, maybe next time, or next week.......

John,
What do you think of a screw on automotive oil filter inline before the nozzle?
It would be easy to see if it's beginning to clog up.

What are your thoughts?

That is the type of nozzles that the CNC cam grinders at work use. They are set on tangent with the wheel(we stick a small allen in the tube and it should touch/apply a little pressure to the wheel circumference). This obviously wouldn't be possible on a surface grinder. Maybe bend them down so they hit the intersection of the wheel/work?

As for filtering, 200 micron bag filter is what they use. I would think a 40 micron auto filter is to fine.

John and MrWhoop are spot on with the coolant nozzle for the MicroMasters . MWhoop's looks like an original nozzle . I tore all of the coolant stuff off and left the tank at the shop I bought mine from , not smart , but I didn't want to haul a rancid tank up the interstate with coolant spilling out . I have plenty of the blue flex lines if ever needed . Anyways , that nozzle should be tucked under the wheel and close to the depth of the bottom of the wheel . It will kinda " squeeze " coolant thru the wheel and part thus flushing the impurities , shoot it over your guard and onto the wall on the left hand side of the grinder .

Did you ever make your missing guard Jeff ?
