A. stepping fine tuning structure, when grinding, stops fixedly vernier knob of tip nail with a machinery.When ground coffee fineness degree is set, user first unclamps and stops tip nail, changes after grinding arranges and locks again vernier knob.
Shortcoming: grind to arrange and select less, stopping tip nail must specifically arrange in the depression or groove of dial, and user wishes that grinding is arranged between two fixed positions sometimes.
B. continuous fine adjustment structure is entered in micro-stepping, and in order to stop the torque force ，Ding grinding stone supporting mechanism of moving grinding stone to be comprised of two parts, first is grinding stone support, and it has a special ear to stop torque, and second portion is the threaded portion that regulates grinding stone position.This two-part structure together acting in conjunction avoided moving grinding stone transmission of torque to threaded portion.
Shortcoming: grinding machine structure is complicated, and parts are many, and processing technology required precision is high, grinding efficiency reduces.
