Nov 22 2017 · In the grinding process of balls the balls are placed on a cast iron plate with grooves parallel to the grinding wheel The process takes place over several stages which can be grouped into two overarching phases rough grinding and finish or lapping operations 211 Rough grinding For the rough grinding stage the grinding wheels tend to be made with silicon carbide grains and vitrified
BALL GRINDING FINISHING AND LAPPING BALL BEARING Ball Outer Ring Inner Ring Abrasive grinding wheels for ball manufacturing are available in both vitrifi ed and organic bond types in shapes 35 or 35P plate mounted The bonded wheel must be very hard and wear resistant due to the slow turning speed of the machine

manufacturing process12 Since race grinding was the bottleneck the researchers focused on this operation3 So that whole concentration are done on the grinding process of bearing ring and failure of ring during the manufacturing II GRINDING Grinding is a process
Its actually a pretty neat process that starts with a metal wire and ends with a perfect shiny ball The first stage in the process is a cold or hot forming operation A wire of metal approximately the diameter of the finished ball is fed through a heading machine This machine has a metal cavity the shape of a hemisphere on each side
The balls are then hard ground They are ground in the same type of machine as used before but either an abrasive is introduced into coolant or the rotating plate is replaced with a very hard finegrain grinding wheel This step can get the balls within ±00001 in 00025 mm
