1.2.5 Safety Practices during Maintenance and Inspection
Always turn OFF the power before performing
maintenance and inspection. Maintenance and inspection
inside the cover is especially dangerous.
(1) Daily Maintenance:
In order to ensure safe operations, the machine must be
maintained and inspected daily.
1) Clean the machine so that any abnormalities can be
found easily.
2) During dry cutting or when machining cast-iron
workpieces, carefully remove chips from the machine
not to accumulate them.
3) Make sure that the gauges for hydraulic pressure, air
pressure, and lubricating oil pressure indicate the
correct values.
4) Make sure that lubricating oil is properly supplied to
the slideways.
5) Drain the air regulator (for machines equipped with
FRL unit).
(2) Precautions on Performing Maintenance and Inspection:
1) Wiring work for 200V AC or higher voltage circuits
must be performed only by an authorized electrical
technician.
2) Never change the parameter settings without
consulting your Leadwell representative. If changed
inadvertently, some parameters will cancel interlock
settings.
3) Do not climb on the machine unless absolutely
necessary.
4) When chips are being discharged with the chip
conveyor, never put your hand or foot on the
conveyor.
5) The drain, provided in the spindle front cover to keep
coolant from entering the spindle bearings, must be
kept clean and unblocked by foreign matter.
6) When a hollow chuck is used, a coolant drain is
provided at the cylinder portion at the rear of the
spindle. This drain must also be kept clean and
unblocked by foreign matter.
