CSW Main Features in Cutting wheel

• Proportion of Fibrous Calcium Sulphate 3-8% of percentage of grits or grits +fillers.
• Formula amending and improving advise: Calcium Sulphate can substitutes of Cryolite, Barite, Alumina and Resin powder percentage partially. It just depends on different formulations. 
• Advised methods for blending/pre-blending: Can be mixed with abrasives, fillers. Can be mixed with resins liquid, be appropriate to longer mixing time to ensure blending evenly.

The suggested dosage is about 3-8%, below is the formulation that we used in 107×1 metal cutting wheel. But this is just recommendation formulation that based on our domestic market. Just for your reference. You can aslo adjust your recipe based on our suggestion.

Take  100g abrasive grains  for example, First we should weight 100g Abrasive grains , and then 30g binding agent +  12g potassium cryolit + our calcium sulphate fiber 6g + others……

46#  White  plated Corundum :  50% White Corundum :   50% Binding agent :  30% ( with high-viscosity resin liquid ) Potassium Cryolit  : 12% Calcium Sulphate fiber :  6% The pigment can be kept the original  proporation.
