TinyTurn – Small Optical Part – SH730
IMPROVED TOOL LIFE
After about 350 pcs of machining, the competitor’s cutting edge wears out. Because of the decrease in the hole diameter, 0.2~0.3mm of hole diameter adjustment is needed. However, TinyMiniTurn maintains an accurate hole diameter until 500 pcs of machining without any adjustment due to a special coating that excels in wear resistance.
