When grade is excessively hard abrasive grain is hard toughness is low and the wheel speed is over for grinding conditions the cutting edges of abrasive grains become dull by proceeding the grinding and the sharpness becomes very worse grinding force is large heat generation mostly occurs and chatter and burn mark also occur much
Dec 01 2006For example the grinding method can be either wet or dry and both can be used with success Dry grinding with the resin-bond CBN wheel has proved to be effective Low feed rates are recommended to prevent workpiece burning during dry grinding Wet grinding with either straight oil or a heavy duty water-soluble oil is very effective
Calculation of Machine Hour Rate For the purpose of computing the machine hour rate each machine (or a group of similar machines) becomes a cost centre and all overheads are charged to a machine cost centre or to different machine cost centres if many
Dec 15 2016High-speed grinding operating at about twice that speed is used on specially built surface grinding machines only which are designed generally for abrasive machining and require appropriately manufactured grinding wheels On the other hand very low grinding wheel speeds in the order of 3 000 to 4 000 fpm (about 15 to 20 m/sec) are needed
