Hylec has developed a preventive
maintenance and refurbishment program that has tripled the life of Marui
Concrete Test Cylinder End Face Grinders to over a million samples.
Grinding of concrete test cylinder end face
has now replaced sulphur or rubber capping in the larger labs. This is because
grinding ensures that samples do not suffer from end failure and the test
results are higher and more consistent.
Hylec’s program includes recommended
maintenance procedures which are carried out by the customer. Also scheduled
machine refurbishment by Hylec prior to the loss of machine grinding accuracy
The refurbishment restores machine to as
new condition and includes replacement of all components subject to wear or
corrosion. It also includes improvements to the machines flushing system to
prevent waste build up in the machine.
A refurbished machine typically grinds the
cylinder end face flat to better than 30 micron and square to the cylinder
sides to within 0.5 degrees. This is well within the Australian test standard.
A refurbishment is recommended after
machine has ground about 300,000 samples. Many machines have had 2
refurbishments, meaning they have ground over a million samples. Refurbishment
halves the cost of machine ownership compared to machine replacement.
Hylec now offers a Water Recirculation
system to use with Grinder with improved waste settlement and easier cleaning.
A cleaner water supply prevents contamination of machine components.
To ensure 100% machine availability, Hylec
offers a replacement for use during refurbishment.
