For proper use of diamond/CBN grinding wheels, shaping and sharpening are necessary during initial installation or when the surface of the wheel is deformed.
1. Mild steel grinding and shaping – sharpening method
在砂輪的外周用油性筆進行標記,讓S45C等生材與之整體接觸(至油性筆記號消失),然後進行正常研磨,直至外周跳動消失。本方法在整形的同時也完成了修銳,因此可以此狀態進入正式作業。
·請使用1180m/min的轉速,比通常轉速稍慢些。
(參考:通常為1700~2000m/min左右)
·如果轉速不能降低,請將切入量降至1mm左右嘗試。
·進給速度采用30mm/min(每分鐘30毫米),近似於靜止的低速進給。
