Chapter 3: End Mill Grinding Operations
3.0 Before You Start: General Safety and Check for Cleanliness
1.(a) Clean the grinder of all of the Cosmeline and dirt if there is any. (b) Check that wheel is mounted
securelyandturningfreely.c)Installtheairlteronorbeforetheairbearingandhookuptheair.Use
teontapetoreduceairloss.Never put any kind of oil or lubricant in either the air lter or the air
bearing xture itself. You should have a minimum of 90 lbs PSI (620kPa).
2. Clean the air bearing xture thoroughly, inside and out. Pull the quill out carefully, leaving the
air on (never move the quill without the air on), and set it aside on a clean rag. Leaving the air on also
allows the air-ports in the sleeve to blow out any debris that may have entered. After removing the quill
and with the air still on, clean the inside bushing with a clean rag and a cleaner, such as acetone, that
will leave no residue.
3. Clean the quill thoroughly with acetone, in the same manner. Check the inside taper of the quill for
cleanliness as well as the outside threads of the collet. Debris that comes between the collet and inner
spindlesurfaceswilla󰀨ectconcentricity. Cleantheoutsideofthequillaimingtoleavenongerprintsor
traces of oil or dust.The smallest bit of oil or dust on the outside of the quill can cause the air bearing to
bind during use. Allow the air to blow through the ports for a minute, allowing the cleaner to evaporate,
then wipe again with a dry cloth and replace the quill carefully.
*Noticethattheairbleedsouttheside,blowingawayanygritandkeepingtheinnerairbearingxture
clean.Periodiccleaningasabovewillinsurealonglifetimeforyourairbearingxture.*Note-when
replacingthequillitisadvisabletoplaceav-blockushagainstthemanifoldandthenguidethequill
through the “V” directly into the air bearing.

4. Check Stylus Height.Thestylusheightshouldbesettotheairbearingxture(tool)centerheight.
Ifitneedstoberesettothisheight,usetheprovided3/8centernderbymountingitintheairbearing
with a 3/8” collet. The face points down, parallel with the x table top face. Raise the stylus to touch the
faceofthecenternderandlockthestylusnuttoset.
