ProtoMat 95s/II 27
Caution! You must first run in the bearings on the high-frequency
spindle when starting up the machine if it has been shut down for a
prolonged period (several months)or if the machine has just been
shipped.
The spindle should be run at 10,000 rpm for several hours the first time
the machine is started up.
Thereafter the control system automatically specifies that the spindle be
warmed up (at 20,000 rpm) for about 3 to 5 minutes whenever the
machine is switched on. The length of the warm-up period is determined
by the length of the shutdown period. It is not possible to set a speed
above 20,000 rpm during the warm-up period. The machine will
automatically switch to the higher set speed once the warm-up period is
over.
BoardMaster
controls these procedures automatically.
