CORUNDUM LAP HIGH
 This
revolutionary polishing lap is a breakthrough in the gem polishing
industry.
It eliminates all excessive heat generated in the
polishing
process, no diamond charge of the lap is needed, no waste of diamond
powder
lost on centrifugal rotational forces, no bending of glue holding the
stone
as water is used as coolant, which makes the lap the best choice of the
cutter.
It is a system reducing the cost of polishing of very hard stones and
corundum.
The lap consists of a diamond impregnated resin bond
with
2 tracks. The outer track for prepolishing and inner track for final
polish.
The lap is recommended for stones of 3-4 mm and up, it consists of a
3mm
thickness high concentration diamond impregnated abrasive material.
The lap is balanced recommended speed up to 2000 RPM.
In order to maintain the lap surface flat, it is very
important to take advantage of all the area while polishing by moving
the
stone across the track from side to side.
When a surface needs dressing, use a carborundum bar
with
large amount of water to smooth the ripples and renew the surface by
moving
it across both tracks while the lap is turning, no scoring needed!!
Afterwards wash lap thoroughly with large amount of water removing all
the carborundum powder. After prolonged use, take a glass plate and
pour
on its surface some carborundum powder, 100 grit, with a small amount
of
water. Move the lap by hand on the glass plate in circles, turning it
for
about 1 to 2 minutes, as needed, till all the surface is straight and
smooth.
Wash lap thoroughly with large amount of water, rinsing
off all the carborundum powder.
