Ceramic materials cooling lubrication

Cooling Lubrication in Grinding of Ceramic Materials 16.4.1 General Facts... 

The cleaning of the cooling lubricant assumes a special importance in terms of aspects such as its function and service life. Ceramic chip particles moreover increasingly attack guides and bearings when they circulate in the machine. Therefore, enhanced demands on the cleaning process must be placed when machining ceramic materials. 

Screw extruders are also used, however, to produce pelleted materials, either as a final product or for further processing, in the food, ceramics, chemical and other industries. Many orifices in a die plate form a multiplicity of extruded rods which are cut into pellets by rotary cutter blades. The extrusion operation is frequently the final step in a sequence of processes which may include binder/lubricant addition, mixing, heating, cooling or vacuum degassing.
