High precision efficiency savings
July 1st 2010 Leicester-based AETC was having to
replace high numbers of bearings in
its CNC machines, so the high
precision machining company asked
Brammer to find a solution.
Brammer provided an analysis of
bearing failures with strategic
supplier Timken. This enabled specific
failure modes to be identified, with
technical solutions introduced to
increase mean time between failures.
Failures were typically due to poor
fitting, a factor which research shows
causes 16% of all premature bearing
failures, and inadequate lubrication,
which is responsible for more than a
third of failures. Brammer and Timken
were even able to diagnose problems
caused by running different bearing
brands simultaneously in one machine.
Brammer set up training sessions
to help inform managers and
engineers of best practice in bearing
specification and maintenance. Cost
savings are now being realised, and it
is estimated that AETC will have to
spend £5000 less on replacement
products as the lifecycle of the
bearings is longer. More articles from Brammer UK Ltd: |
