A Study on Grinding Tungsten Carbide with Ultrasonic Assisted
In order to cope with high demanded industry requirements.The super-hard alloys such as Tungsten Carbide have been widely used in aerospace and defense industries.So far,the grinding operation is still the most popular machining process being used to cut these materials in shape.But,owing to the nature of these materials mechanical properties,always made it very difficult to grind as well as to cut.Nevertheless,the allowable grinding parameters are resisted to very limited range and always require use very expensive super abrasive grinding wheel.Recently,study by many researchers show that the ultrasonic assist grinding had the advantage of higher material removal rate,less cutting force and lower cutting temperature.In the mean time,the tool life had been improved greatly.In this study,the conventional GC grinding wheel was used in the experiments to study the material removal rate; grinding force; surface roughness as well as specific grinding energy with and without the ultrasonic assist.The results show that these difficult-to-cut materials can be ground easier with proper ultrasonic assist and low-priced grinding wheel.
