PROBLEM TO BE SOLVED: To provide a method for polishing a hard metallic material, which performs both a smooth polishing action for reducing the surface roughness of a work made of the hard metallic material and a grinding action for adjusting the outline dimensions of the work, can increase a polished amount (=charged amount) of works for each batch charged into a polishing tank, and can increase productivity by eliminating a sorting step for work and media. SOLUTION: This method for smoothly polishing a hard metallic material includes a polishing step A16 for polishing a work without using media by charging the work, abrasive grains A crushed according to the advancement of the polishing, and water in the polishing tank 1 using a flow barrel polishing device in a polishing device and a washing step A17 for flushing the polishing tank by rotating a rotating disk 4 after washing water is supplied into the polishing tank 1 and stored in the polishing tank 1, and discharging the abrasive grains A and water used for polishing and polishing waste to the outside of the polishing tank 1 together with the washing water to remain only the washed work in the polishing tank 1.
