Grinding operation SlideShare
INTRODUCTION TO GRINDING PROCESS • • • It is the only economical method of cutting hard material like hardened steel It produces very smooth surface, suitable for bearing surface Surface pressure is minimum in grinding It is suitable for light work,which will spring away from the cutting tool in the other machining processesGrinding operation is carried out be operating both table traverse wheel and vertical feed hand wheel 16 Cylindrical grinding machine It is a process of grinding curved surfaces Surface may be straight or tapered Work piece is mounted on two centers, one is tailstock centre and the other is headstock centre Head stock center may or may not revolve 17 Working principle 18 (No Transcript PPT – Grinding machines PowerPoint presentation free to • Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant The coolant also benefits the machinist as the heat generated may cause burnsGrinding machine ppt SlideShare Centreless internal grinder This machine is used for grinding cylindrical and tapered holes in cylindrical parts (eg cylindrical liners, various bushings etc) The workpiece is rotated between supporting roll, pressure roll and regulating wheel and is ground by the grinding wheelMP1 Grinding Machine SlideShare Grinding: Grinding is a process of removing material by abrasive action of a revolving wheel on the surface of a workpiece in order to bring it to required shape and size The wheel used for performing the grinding operation is known as grinding wheel It consists of sharp crystal called abrasive held together by a binding material or bond The wheel may be a single piece or solid type or Grinding SlideShare
