Used Silica Grinding
Titanium and Titanium Alloys
· Grinding wheel selection – Silicon carbide can be used at surface m/min ( ft/min) to give optimum surface finish and minimum wheel wear. The high speeds essential with these wheels produce intense sparking which can cause a fire hazard. The work piece should be flooded with coolant to reduce sparking. Vitrified bond A60 wheels, hardness JM have been successfully used .

Basic Facts About Colloidal Silica Densifier
The commonly used concrete densifiers are colloidal silica, sodium silie, potassium silie and lithium silie. An older densifer, magnesium fluorosilie, is rarely used anymore. Differences in silica The goal of all concrete densifiers is to deliver a reactive form of silica down into the microscopic pore system of the cement paste. They all use a liquid to carry the silica. The ...

Wafer Backgrinding Services | Silicon Wafer Thinning Services
The backgrinding process involves using a diamondresin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemicalmechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or chemical etch. Wafer backgrinding starts with a ...
