TOOL SHARPENER
Not much CNC work as this was a build as you go kind of project.
I have a Darex end mill sharpener and it works great and also use A Foley saw sharpenener as a bench grinder, but,
never used the Foley much because the grinding dust went everywhere.
Shop space is rather limited.
As the used / chipped / broken carbide end mills and lathe tools start to pile up wanted something to prep them for finish grinding.
So started looking at all that "stuff" one collects over time to see what could be used to make some general use carbide grinding fixtures.
Some thoughts on the matter included:
1. Cheap / "this is not going to cost much" ( hobbiest creed!)
2. Use the "stuff" you have
3. Must be easy to setup, rather accurate to minimise use of expensive diamond
wheels for rough sharpening.
4. Be able to sharpen carbide lathe tools including inserts and end preparation
of broken / chipped / end mills.
5. Keep it small, is movable, and can be easily stored away.
So the attached file shows some of the things made.
Note: When you make a fixture the mounting needs to be accurately done as that provides for easy and accurate setup. Keep things symetrical about drilling, based plates
square etc.
SAFETY NOTE:
Pay attention to recomended and max rpm of wheels. Don't believe the cheap stuffs claim that it's good to 30K RPM. Test anything you make for runout and vibration. I put a rated 35K small wheel in a bench mounted die grinder and it went into vibration at about 15K bending the tool steel arbor ...almost jumped off the bench ( it was rigidly clamped down). Be carefull!
