10. The use method of the special grinding machine for grinding the spherical base surface of the swing type spherical roller is characterized by comprising the following steps of:
(1) the rollers are placed on the material channel, the rollers are sequentially arranged in the material channel and roll downwards along the roller path, and the roller at the foremost end rolls onto the transition plate under the self-weight;
(2) the headstock is driven to swing to the foremost side through the swing shaft and the driving mechanism, and the feeding unit acts to push the roller into the clamp;
(3) the headstock is driven to swing reversely under the action of the swing shaft and the driving mechanism, and the roller is contacted with a rotating grinding wheel in the swing process to realize grinding treatment on the roller;
(4) when the headstock swings to the last side, the knockout unit acts to knock down the rollers on the clamp, and the knocked-down rollers fall into the blanking unit;
(5) after the material beating is finished, the headstock swings reversely until the headstock swings to the foremost side again, which is a working cycle.
