Surface Grinding wheel head feed fine adjustment mechanism

A flat grinding wheel head feed fine institutions, mainly with a worm gear, a ratchet and pawl indexing. Characterized in that: the worm wheel fixed to the drive shaft, the worm and worm gear engagement, the fine feed cutting tools for the two-stage, one end of the worm shaft based set number one, so as to rotate the worm, and the rotation indexing ratchet also achieved a fine tuning to. Its system by a pawl is pressed while abrasive wheels the handle affects the ratchet Diamond blade by the worm, for another period of feeding, the ratchet drive the feed worm may be terminated by step and make it into the lever to change the feed rate difference of one times. The amount of feed pawl by a bolt of travel restrictions derived.
