- Check and potentially replace the end position dampers
Orientation
Besides the software end positions and the emergency stop switches, the end
position dampers are another safety device to protect the machine from damage.
Their job is to absorb the impact force to the spindle bearings.
Therefore, regular inspection of the end position dampers for damage is necessary
to prevent damage to the spindle and its bearings.
Power off the machine, depressurize the hydraulic system by
opening the accumulator relief valve(s), and protect against
accidental power on.
Requirement
To replace the end position dampers on the bearing supports of the ballscrews, the
following utilities and tools are needed:
- servicing, testing and maintenance schedules/logs of the customer,
- rags for cleaning,
- various sizes of jaw and box wrenches, and Allen keys.
Depressurize the hydraulic system by opening the accumulator drain
valve (e), turn off the machine and prevent it from restarting.
