How to

The selection of products
Abrasives We mainly use
Silicon Carbide and Aluminium Oxide grains. Silicon
Carbide is harder, sharper and tends to cut faster
and produce finer scratch patterns on most surfaces.
Aluminium Oxide is more durable, lasts longer and
is more aggressive on certain applications such as
hardened steel.
Density
Normally, it will be more density and more hard, if
the weight of the wheel is big. But it is not always
like this, it also depend on the combination of abrasive,
glue and fiber. Under identical conditions harder
density wheels cut faster, last longer and produce
finer finishes than softer density wheels. Softer
density wheels offer greater conformability and less
tendency to load or burn the workpiece.
Color The color depends on the color of abrasive,
green wheels use green Silicon Carbide. So for different
workpiece of different material, we must use different
color of wheel. But it is not always like this, because
we add some dyestuff according to the requirements
of our clients.
Size
The size(diameter and width) depends on the workpiece
and machine, and the shape and diameter of the core
mainly depend on the shaft of the machine.
Use
Maximum wheel life and best surface conditioning results
can be achieved by closely adhering to the following
recommendations.
Speed Wheel
speed is an important factor in that it affects product
finish, rate of cut, and wheel life. The actual speed
should decided by the material of the workpiece and
required finish effect. Never exceed the maximum R.P.M.
rating of the wheel.
Direction
Convolute Wheels must always be run in the direction
indicated by the arrow printed on the side of each
wheel. Other kind of Wheels can be run in either direction.
Pressure Light to medium
pressure is recommended for most operations. Flap
Wheels require much lighter pressure to perform properly
than other wheels. In all cases, avoid excessive pressure
which may result in wheel deformation and damage to
the work surface.
Oscillation
Oscillation may be used to break-up scratch lines
and produce a more uniform finish. |
