Machine Tool Initiating Repair Process
Machine Tool Initiating Repair Process - In spite of all precautions, natural wear will develop in the working parts of machine tools and a stage is reached when the fault must be corrected to prevent further rapid deterioration and to maintain the accuracy of the machine to within certain prescribed limits.
The form is used by the inspection department to notify the maintenance department that the machine has been inspected and that repairs are necessary; it will be seen that the form states the nature of the work to be done and the estimated time required and asks when the machine can be made available.
It
is
important
to
maintain
a
record
of
the
nature
and
cost
of
all
repairs
carried
out
and
such
a
record,
kept
by
the
maintenance
department.
Examination
of
this
record
can
bring
to
light
those
elements
of
machines
which
need
improved
servicing,
more
frequent
inspection,
or
modification
to
the
machine
design.Further,
such
records
provide
the
data
for
decisions
regarding
the
need
for
reconditioning
and
replacement.
Few records of this nature have been kept by companies in the past, with the result that very little factual information is available with regard to the cost of maintenance in relation to machine life and performance; thus the economics of replacement decisions have been clouded and much information valuable to the machine tool designer has not been available.
As already stated, this record card will enable decisions to be made regarding the need to withdraw the machine, not only for corrective action but also for reconditioning; by reconditioning is meant the complete stripping and rebuilding of the machine to bring it back to a condition which is at least as good as the maker's original specification.
The precise cost of reconditioning cannot be determined until the machine has been stripped down and the extent of the work to be done determined; for the general run of machines, however, reconditioning will usually cost between 30 percent to 50 per cent of the price of a new machine.
