Various Methods of producing grinding wheel
:yinglong :2018-02-23 17:19:21
There are many different kind of manufacturing methods depending on bonds. As below:
| Bond Type | Code | Major Components | Firing Method / Temperature | Applications | Features |
|
Vitrified |
V |
Feldspar / Soluble Clay
|
Continuous kiln / Bell kiln / Downdraft kiln
1200-1350°C
(2192-2462°F)
|
Machining, Free-hand grinding, Super finishing, Honing, Pulpstone |
・Use feldspar and/or soluble clay as binder
and bake at high temperature of 1300 degrees
C after complete drying.
・The most common manufacturing method.
・Easy to adjust grade and structure.
|
|
Resin |
B・BF
*BF=Resin and
Reinforced
|
Phenol resin, other artificial resins |
Low temperature electric oven, around 200°C (392°F) |
Rough grinding, Free-hand grinding, Cutting, Machining, Lapping |
・Use synthetic resin as binder and
harden at low temperature of 200 degrees C.
・Springy and resistant to high speed rotation.
・There are wide variety of wheels according
to purposes.
|
|
Rubber |
R |
Natural / synthetic rubber, Sulfur |
Low temperature electric oven, around 180°C (356°F) |
Cut off / Centerless grinding wheel |
・Use natural or synthetic rubber as binder
and harden at low temperature of 180 degrees C.
・Springiest.
・Ideal for thin wheel.
|
|
Silicate |
S |
Silicate soda (water glass) |
Downdraft kiln 600-1000°C (1112-1832°F) |
Sharpening, surface grinding |
・Use silicate soda as binder and harden at low
temperature. Ideal for sharpening and
polishing of wood saw.
・Silicate soda acts as lubrication.
・For soft grade wheels.
|
|
Magnesia |
O |
Magnesium oxychloride cement |
Unfired wheel, harden at ordinary temperature. |
Sharpening, surface grinding. |
・Use kind of cement as binder and harden at
ordinary temperature. Reduce effect of
grinding heat, ideal for surface grinding of thin
materials.
・Provide good grinding performance with low
speed.
|
|
Shellac |
E |
Shellac (natural resin) |
Low temperature electric oven, around 170°C (338°F) |
Tool grinding, Lapping |
・Use natural resin as binder and harden at
low temperature after compression molding.
Ideal for low speed lapping.
・For soft grade wheels
|
Manufacturing Method of Resin Bond Grinding Wheels
Manufacturing process of our main products "resinoid bonded wheel" are introduced below.
 |
・Use Abrasive grains, filling and bond.
・Compounding ratio varies with each product.
What is filling?
Except abrasives and bond, grinding wheel contains many compounds as filling. There are many
purposes of adding filling, such as performance increase or coloring (green, red or black etc.).
|
 |
All materials are dried after mixing thoroughly. |
 |
・Forming in mold
・Insert special glass fiber (glass cloth) as reinforcement during the molding process.
 |
 |
Demold after pressing |
 |
・Fire wheels completely at around 200 °C (392°F)
・Firing is a very important process that influence its grade and quality.
|
 |
We inspect all products to keep high quality and safty. |
 |
Perform many test for maintaining high quality and safety of the products. |
 |
Print and stick label on the products. |
 |
