Grinding fluid application is important to control thermal related problems while grinding titanium alloys. Conventional fluid delivery systems are not able to deliver grinding fluid deep into the grinding zone because of the presence of a stiff air layer around a rotating grinding wheel. A newly developed pneumatic barrier system is used in this experimental investigation to penetrate the air layer so as to deliver fluid into grinding zone. Dry, flood cooling and flood cooling with pneumatic barrier conditions are used to explore the influence of these environmental conditions on grindability of titanium grade 1 workpiece. It is seen that under flood cooling using pneumatic barrier, better grinding performance is obtained than conventional flood cooling condition.

Abstract


Grinding fluid application is important to control thermal related problems while grinding titanium alloys. Conventional fluid delivery systems are not able to deliver grinding fluid deep into the grinding zone because of the presence of a stiff air layer around a rotating grinding wheel. A newly developed pneumatic barrier system is used in this experimental investigation to penetrate the air layer so as to deliver fluid into grinding zone. Dry, flood cooling and flood cooling with pneumatic barrier conditions are used to explore the influence of these environmental conditions on grindability of titanium grade 1 workpiece. It is seen that under flood cooling using pneumatic barrier, better grinding performance is obtained than conventional flood cooling condition.
