Spindle Break-In
Before subjecting the spindle to operational loads,
it is essential to complete the break-in process.
This helps maximize life of spindle bearings and
other precision components by thoroughly lubri-
cating them before placing them under load.
After spindle break-in is complete, we recommend
changing headstock and gearbox oil to remove
any metal particles or debris that are present from
the assembly and break-in process.
The break-in must be performed in succession
with the Test Run procedure described in this
manual, as the steps in that procedure prepare
the lathe controls for the break-in process.
DO NOT perform this procedure indepen-
dently of the Test Run section. The lathe
could be seriously damaged if the controls
are set differently than instructed in that
section.
