difference between roughing and finishing in machining

higher feed rate and depth of cut are employed for this step so that high stock removal rate is obtained. this step is called rough cut or roughing pass. it cannot provide good surface finish and close tolerance. after rough cut, a finish cut or finishing pass is carried out to improve surface finish, dimensional accuracy and tolerance level inquire now

fine grinding of silicon wafers: designed experiments

back grinding is normally done by two steps: rough grinding by grinding wheels with large size of diamond grains; andne grinding by grinding wheels with smallne diamond size. however, sometimes there is a need to regrind the wafers that have been background previously. and this regrinding is typically done byne grinding only.inquire now
