Monocrystalline diamond suspensions are highly effective in removing material quickly while delivering a polished surface with minimal scratch depth. This diamond variant is less brittle due to the absence of grain boundaries, making it ideal for stock removal. The suspension comprises carefully selected diamond particles mixed with an oil-based carrier solution. The oil base carrier has a low viscosity, allowing for better stock removal and fewer inclusions. The control over particle size distribution, diamond concentration, and the stable emulsion is stringent to maintain consistent effectiveness. These diamond suspensions are recommended for materials susceptible to water due to their hygroscopic nature.
