PROBLEM TO BE SOLVED: To provide a method and apparatus of centerless grinding capable of through field centerless grinding workpieces having large machining allowance highly accurately and highly efficiently without reloading workpieces and adjusting the angle of an adjusting wheel. SOLUTION: In the method of through field type centerless grinding wherein through field type grinding is conducted with workpieces W fed on the blade 3 between a grinding tool 1 and the adjusting wheel 2 and axially moved while rotated, machining allowance for one through field grinding is set to 1/n (n represents a natural number) of required machining allowance in a allowable machining allowance range capable of securing desired machining accuracy; and the return bar 10 arranged above the blade 3 is made to move axially by means of a cylinder device 11, and the workpiece W is returned to an entrance along the blade 3 and then through field grinding is conducted again after moving the adjusting wheel 2 a specified distance toward the grinding tool 1 and adjusting the position of the adjusting wheel 2. Required machining allowance is removed by repeating this through field grinding n times.
