Filtering out tungsten/silicon carbide dust from grinding coolant is a very challenging process. As long as carbide remains in the coolant, it leaches cobalt and degrades the coolant. Hence, not only the coolant needs to be correctly selected but the filtration system as well.
If the dirty machine coolant recirculates, fine carbide particles are pumped to the spray head and sprayed onto the work area. Some of the particles are thrown into the air, where they can be inhaled. Other particles are reground into even finer particles. These recirculated particles will cause rougher grinds affecting surface finish and will increase the chance of burning during grinding process.
Our products solve the following problems that carbide grinding machine users face-
- Our customers report a doubling of coolant life. Because of the clean coolant, customers can set higher speed and feed rates with no chance of burning and improve the life of grinding wheel.
- We design the systems to remove the tungsten/silicon carbide dust particles and tramp oil and grinding wheel particles.
- We take the environmental impact assesment of our filtration systems very seriously. Hence, we use regenerative filter media, i.e., the filter media is ‘cleaned’ or ‘backwashed’ at a set frequency and not discarded.
