Retrofitting refers to the addition of new technology or
features to older systems this definition gives an almost all
information about the word retrofitting. When we say that
retrofitting related to some component that mean we try to
upgrade that component and improve their efficacy through
a present technology.
But here we only talks about the retrofitting in lathe
machine at time Retrofitting is the process of replacing the
CNC, servo and spindle systems on an otherwise
mechanically sound machine tool to extend its useful life.
Rebuilding and remanufacturing typically include a CNC
retrofit. The anticipated benefits include a lower cost
investment than purchasing a new machine and an
improvement in uptime and availability. But there are often
other unanticipated benefits to retrofitting including lower
energy costs, higher performance and a new level of
manufacturing data accessibility.
Assuming the machine tool is generally in good shape
mechanically, CNC retrofitting is typically the lowest cost
solution to improve the overall performance of an older
machine tool.
Though some electrical subassembly is often performed
at the retrofitter’s business location, most of the work can
be completed at the machine site, avoiding costly machine
rigging and transportation costs, and minimizing the time
that the machine is out of commission.
Rebuilding typically includes the repair or replacement
of some worn mechanical components such as ball screws,
lubrication pumps, safety interlocks, guards, hoses, belts
and electrical wiring. The rebuild is typically performed at
the rebuilder’s facility, so there may be additional
transportation and rigging costs.
Remanufacturing goes a step further to repair or replace
mechanical components to the original, as new, factory
specification. It is likely that the machine will be
completely disassembled, cleaned, inspected, repaired and
painted. All pneumatic, hydraulic and electrical systems
will be updated. The machine may also be modified or have
mechanical accessories added to re-purpose it for a new
application. Practically without exception, remanufacturing
will take place at the remanufacturer’s site.
The main objective of the retrofitting in lathe machine is
to improve the existing conventional lathe machine to
provide it features of CNC machine with very lower cost
than the new CNC machine.
Rather than above main objective there also several
objectives of the retrofitting which is given below
To Increased productivity and improved control of
machine.
Far superior repeatability.
To reduced machine downtime.
Fast machining cycles.
High accuracy, high feed-rate.
To increased accuracy and part finished due to
controller.
User friendly programming and simulation
software enables 3D graphic representation of job
with automatic generation of G-Code.
Eliminate additional tooling cost.
The Up-gradation Package is less expensive and
more readily justifiable.
