Fírst of a11, wash the protective grease away using some petroleum, then lubrífícate
the whole apparatus particulary where same is equípped wíth oi1 feeders.
After having had the machine linked to the electricity, put it in gear acting over
the expressely made switch and check that the gríndíng wheel pivots towards the índícated
dírectíon.
Vertícal movements of the wheel-head
To effettuate quíck approachíng feed use handwheel, whilst micrometríc approaching
feed, allowing reading of 0,01 mm., is obtained by inserting the cog on the same handwheel
(dísinsert cog duríng quíck feed).
Maíntenance
1f the mícrometríc feed sensitivity decreases, adjust the screws that unloose or
tighten the motor carryíng plate to the column (for the mod. LA 300 LB 300 - 11-12) (LF 350
LC 400 LC 500 LP500/200 - 19-20).
You can obtain, in this manner, a sweet sliding movement during the wheel handling.
Furthermore íf you notíce a too strong deflectíon ín the column posítíon during the
workíng of the machíne, adjust the ferrule (for the LA 300 LB 300 model it is índícated wíth
the number 4, LF350 LC400 LC500 LP500/200 - 11) just to take up slack, taking care not to stop the
column rotation. 1f a bíg slack were between the worm and the worm wheel (that work for
the vertícal mícrometric feed), unloose the screw stoppíng the carryíng worm cambush; turn
it around ti11 to take up the existíng slack, Afterwards, tighten the lockíng screw agaín.
Gríndingwheels qualíty choice
To have the highest efficíency of the machíne choose the wright grínding wheel type
accordíng to the kínd of material you have to work. Generally íf you must work cast íron
materíals adopt silíconcarbíde grinding wheels whíle the steel materials want whíte corundum
grinding wheels.
A hígh effícíency can be obtaíned whit resínous bond grinding wheels.
To choose the wright grindíng wheel graíns hardness, don't forget the fínishing and
the harnnee if the material that has to be worked; to thís purpose we suggest you to use soft
gríndíng wheels for hard materials and víceversa. 1n any case ít ís advísable to contact the
manufacturers of wheels which can give you advices for the best choice.
Keep the gríndíng wheel always slant towards the ínsíde to avoíd the heating of the
material must be worked. This can be obtained better wíth the optíonal L 21 «Semí-automatíc
sharpener» supplied on request.
