73. Diamond Grinding has many variables. When you understand some of these, you can solve a lot of problems
without a lot of bother and expense.
PROBLEM
Machine will not start
/ run.
Machine is not
grinding at all.
The diamonds are
wearing out too fast.
Problem solving
CAUSE
No power is present at
cable end.
Machine is trying to
start on glue or other
sticky substance.
Power lead is too small
in capacity or too long.
No blades /
accessories in unit.
Very hard concrete or
glazed topping on
concrete.
The concrete is:
*Soft
*Abrasive
*Rain Damaged
*A rough finish
(Scarified or shot
blasted).
NOTE: THIS IS A GUIDE ONLY
REMEDY
Check the power is present
with another tool.
Clear a patch with a scraper
and grind into the glue a
little at a time.
Upgrade the power lead to
2.5mm² (20meters max) or
4mm² (50 meters max).
Fit blades.
Note; check wear
on machine.
Turn dust extractor down /
restrict flow. Only just
control the dust from
escaping.
Place river sand or cement
on the floor.
Use softer grade of diamond
tooling.
Use coarser diamond
tooling.
Use a powerful dust
extractor to remove as much
dust as possible.
Use harder diamond matrix.
Use tooling with more
segments or area² of
segment.
EXPLAINATION
Using another tool confirms power
is present
This means it only tackles a small
amount of glue at a time and
keeps the glue residue coated with
dust, preventing glue sticking and
building up on the diamonds.
The long / small capacity cable is
too restrictive and can't allow
enough power through for the
machine to start / run properly.
The extra dust accumulating on
the floor acts as an abrasive
between the segments and the
floor thus exposing the diamonds
better.
The sand is an abrasive as
described above.
The softer grade will expose the
diamonds better.
The coarser diamond tooling can
get through hard toppings without
wearing out the diamonds too
fast.
The dust, as described acts as an
abrasive between the segments
exposing the diamonds
prematurely, wasting them.
The harder segments don't expose
as easily.
The tooling with more segments
or area² doesn't have the same
weight on them, reducing wear.
