Manual on line
1.Main application of the
product
1.1.Having characteristic for well grinding
precise, high speed, saving time and labor and durable,
Common abrasive products are mainly used for grinding,
cutting black metal and non-metal material and widely
used for industries i.e. mechanism manufacture,
steel and metallurgy and construction.
1.2 Depressed center wheel is mainly used for
industries i.e. mechanism manufacture, metallurgy,
shipbuilding and automobile and can be grinded welding
point, welding line, cutting notch and removing
rust as well as its grinding efficiency is high.
1.3Having characteristic for high grinding speed
and durable, fiber reinforce resin cutting discs
is suitable for cutting metal, conduit material,
profiled material and track.
2.Installition operation, maintaining and troubleshoot
3.1 knock on grinding wheel with wood stick
before install if any dumb sound caused the crack,
if not, we can install it.
3.2 Screw down grinding wheel with flange pan
prescribed in conformity with standard when install
it. Elasticity pad shall be applied to between flange
and grinding wheel and its thickness is from 1mm
to 2mm.
3.3 Screw down grinding wheel with special purpose
wrench and forbid tapping.
3.4 Certified guard must be provided when use
the grinding wheel.
3.5The grinding wheel shall be tested five minutes
at the maximum work linear velocity before use it.
If no problem, it can be used but can not over the
mark linear velocity.
3.6Forbid to push and press with lever and strong
press when process grinding wheel.
3.7Grinding wheel that is not work on end surface
cannot permit to operate as special purpose end
surface.
3.8Handle with care and protect from severity
shake and impact when carry grinding wheel.
3.9Storage location of abrasive products is
keep in proof humidity and freeze place.
3.10Grinding wheel with resinoid bond shall
be rechecked when its storage term is beyond one
year and can be used after certification.

on easy to burn and high precision requested
such as tap, gauge etc.
|
|
Black silicon-carbide
|
For grinding workpieces
of the low tensile strength such as iron
casting of gray and white, steels etc.
|
|
Green silicon-carbide
|
For grinding the rigid alloy,
reamer, stone material,glass etc.
|
2.The selection of grain No.
| 16#-24# |
On forged steel workpieces,
for deburring coarse grinding, cutting
etc.
