When you forget to change your car's engine oil, it won't
take long for many other engine problems to occur. If the metal-to-metal
contacts are not lubricated, car engines can get hot and dirty, parts break and
get stuck to the point where expensive replacement work is needed.
Using the ball screw
without the desired lubrication and ignoring the metal-to-metal grinding
contact has essentially the same effect as not changing the engine oil, which
generally results in an unexpected downtime for the workshop machine.
Fortunately, keeping a thin film of lubrication, oil or
grease constant solves many inappropriate problems, reduces friction and
minimizes torque, prolonging screw life and working efficiency.
Lubrication applied:-
Whether you choose grease or oil, the ball screw must be
clean and dry before lubricating it. Remove the accumulated parts of the grease
or oil that have been in recent months so that they are not trapped in the
balls or the screw cables, damaging the screws and the parts to which they are
connected.
Do not apply too much lubricant at a time. Make sure the
screw is wet when touched with enough lubricant to avoid wet metal-to-metal
contact, do not wet the wet and wet ball screw from the rest of the machine.
Grease vs. oil
Knowing that the ball screw must be lubricated
semi-regularly is only half the battle. The other half knows exactly what type
of lubrication should be used.
Oil is sometimes considered less maintenance than fat
because it has less maintenance than fat and tends to remain better inside the
ball nut.
The oil generally requires a pump and a filtering system and
works well when the operating speed, load size and temperature are low or
medium. However, if any of these three factors is too extreme, the oil coating
becomes useless, which can cause friction and damage from metal to metal.
Grease, on the other hand, can enter directly into the screw
or a ball nut when drilling and pumping grease. The grease can handle high
speeds and can be used with additives to produce synthetic lubricants that can
handle more extreme temperatures, load sizes and speeds. However, the fat
should not be used for molybdenum or graphite di-sulfide. This is because the
friction level is really too low.
