Broaching is commonly used for machining fir tree slots on turbine disk, which has outstanding
advantages and disadvantages, such as high quality machined surface, high manufacturing accuracy and high
productivity as well as fa st tool wear, extremely high processing costs and long preparation time, poor process
flexibility. Utilizing the electroplated cubic boron nitride (CBN) profiled grinding wheels and single sided local
profiled grinding process, the experiments of FGH96 tur bine disk slots are carried out. The results show that the
high precision of slot profile can be achieved by the developed process. Using the given experimental parameters
n =48000 rpm, a p =0.002 mm, v f =100 mm/min and 600# electroplated CBN profiled wheel, the profile error of
FGH96 slots is within ±0.012 mm, and the grinding surface roughness is less than Ra0.8 μm. After four whole slots
are machined completely, the grinding wheel still has grinding capability, which proves that 600 # electroplated
CBN prof iled wheel can meet the grinding needs of FGH96 turbine disk slots.
