Description:
<jats:p>This paper described a miniature refiner plate and its manufacturing. The plate was used for preparation of timber microfibril. Grinding teeth used Archimedes spiral groove as a path, the path effectively increased grinding trajectory path; all grinding teeth and alveolus unit were in the same equal length, effectively increasing the flow and easy to manufacture. The semifinished plate was processed in an ordinary lathe, then the processed surface was quenching, ensuring hardness, wear resistance and fatigue strength.</jats:p>
