9.2 Maintenance
TheTormachToolingSystemAutomacToolChanger
requireslilemaintenance.Periodicallyinspectthe
following:
1. Ensurethatyourairiscleananddry.Alter/regulator
unitshouldbesucientforsupplyingdryair,aslong
asyouperiodicallydrainyourcompressor.
2. Thelinearguidesshouldbeperiodicallywipedclean
andgivenalightcoatofwayoil.
3. TheDelrinbearingonthecarouseldoorshouldbe
periodicallyoiledwithwayoil.
4. Ifchipsaccumulateinsidethecarousel,itisadvised
toblowchipsclearofthecarouselandtraytoprevent
themfromobstrucngtoolchanges.(Alwaysweareye
protecon.)
Addionally,aerinstallingtheATCyoumayndthatyou
areusingyourpowerdrawbarmorefrequently.Power
drawbarmaintenanceitemstoconsiderare:
1. Periodicallyghtenthesetscrewonthespindleange.
2. Periodicallyensurethatmounnghardwareissnug
andfastenersareght.
3. Belleville washers are wear items that have a service
lifeof~30,000toolchanges.Ifyouexperiencecollet
slipornocedeterioraonofthebellevilles,replace
themaccordingtotheprocedureoutlinedinthePower

9.3 Troubleshooting
Mechanical Issues
Binding
IfyourATChasnotbeenproperlyalignedyoumay
experiencebindingasthecolletdescendsoverthe
toolholdershank.TheATCcarouselmustbeinaplane
perpendiculartothespindleaxis.Thebestwaytocheck
thisistoplacealongdowelinadrillchuckorsetscrew
toolholder,thenposionthattoolholderinanopentray
slot.Asyoujogthespindledownoverthetoolholder
shank,watchtheendofthedowel.IftheATCisproperly
aligned,theendofthedowelwon’tmoveasthecollet
slidesovertheshank.AligningtheATCismeconsuming
todoproperly,butoncesetthealignmentshouldnot
change.
Collet Slip
Colletslipcanresultfromavarietyofcauses.Thebestway
topreventcolletslipistomakesurethatyourtoolholders
andtheboreoftheTTSR8colletarecleananddry.Wiping
themdownwithalcoholoracetoneisagoodwayto
removewayoilorcunguidthatmaycausecolletslip.
Theprocedureforadjusngthepreloadonthebellevilles
isoutlinedinthepowerdrawbarinstallaonguide
(TechnicalDocument31706,includedonyourATC
sowareinstallaonCD).Becausethebellevillewasher
preloadalsoaectstheoperaonoftheATC,certainparts
ofthisprocedureareworthrepeanghere:
1. Whenadjusngthepreload,makesurethatyouhave
aregulatoronyourairlinesettoatorbelowthecutin
pressureonyouraircompressor.Forinstance,ifyour
regulatorswitchesonat90PSI,andyourregulatoris
setto95PSI,theactualairpressureatthedrawbar
couldbeanywherebetween90and95PSIdepending
onthetankpressure.Thisisbad–ifyousetthe
bellevillepreloadwhenyouhave95PSItoworkwith,
thedrawbarwillnotproperlyreleasewhenyourair
pressuredecreasesto90PSIandyouareatriskfor
crashingtheATC.
2. Thehighertheworkingairpressure,themorepreload
youcangetonthebellevilles.Ifyourcompressor
canbeadjustedtomaintain100PSI,youcanrun
withhigherpreloadthanyouwouldat90PSI.We
recommendaminimumof95PSI,butifyouhave
colletslipproblemsyoumayneedtoincreasethe
