Q1: How to Make a Grinding Wheel? 


1. Mixing the components

The basic component materials of grinding wheels are abrasive grains, bonding materials. They will be mixed together by a MIXER. The abrasive grains include: silicon carbide, aluminum oxide, zirconia alumina and others. Bonding materials of resin-bond wheel are synthetic resin that can be cured by thermal,one of the first common resin bond materials is Bakelite(phenolicresin), other resin such as epoxy resin, polyurethane are also used as bond materials.Most resin bond grinding wheels need a reinforced material, discs of reinforcing fabric woven such as glass fiber. This reinforced materials will be load in during the next step, molding.

2. Molding

The mixture is poured into the mold and then compressed by a hydraulic press(ROTARY MOLDING PRESS or LINEAR MOLDING PRESS). In this step, the press piston compacts several basic elements: abrasive mixture,reinforced glass fiber,Paper label and metal ring.  The shaped grinding wheels are 

3. Curing

In this step the wheels are heated in a programmed CURING OVEN or FURNACE. After firing, the shaped wheel become hard and strong enough to cut/grind at a high speed.

4. Labelling and Packing

5. Grinding Wheel Test

Normally, resin bonded grinding wheels need pass several basic test before packing and sending to users: 

  • rotary speed test

  • grinding /cutting test

  • static balance check



Q2: What kind of Grinding Wheel/Cut-off Wheel I want to produce?


Resin-Bond Grinding  Wheel / Cut-off Wheel has several layers. The following are normal wheel layer structure. Simply, More Layers, more functional stations are needed in the press Machine. Tell us what kind of wheels you want to produce, we introduce you a suitable grinding wheel making machine.

  • Diameter of the wheels

  • Layers of abrasive mixture

  • Glass Fiber Net

  • Label/Paper and Metal Ring(Collar)

Other requirements.

E.G.: D115mm, 1 - layer abrasive mixture, 2 - layer glass fiber nets (nude), press label and 1 metal rings
