The invention discloses a full automatic 
grinding machine for a 
piston ring inclined end surface. The full automatic 
grinding machine comprises a 
machine bed, an automatic loading and unloading rack, a composite 
processing table, a power head rack, a material collection rack and two parallel guide rails which are arranged on the machine 
bed, wherein the automatic loading and unloading rack and the composite 
processing table are arranged on the two ends of the two guide rails, the power head rack and the material collection rack are arranged on the two sides of the two guide rails; the automatic loading and unloading rack comprises a 
material storage rack, a material delivering slide table and a material delivering cylinder, the composite 
processing table comprises a processing slide table and a slide table displacement 
servo motor; the power head rack comprises a shell, a hollow axle 
pipe is arranged in the shell, an electromagnetic chuck and a positioning disk are sleeved on one end of the axle 
pipe near to the guide rail, and the 
material storage rack comprises a 
material storage rod, a guide rod and two inverted L-shaped connection racks. The 
piston ring inclined end surface is more simply processed, the processing precision is high and the processing efficiency is high.
