摘　　要：本文研究了高效深磨技术中的热渗透。研究发现,在高效深磨(HEDG)加工中,工件的热渗透层很浅,随着工作速度的增加,磨削热趋于集中在工件的表层,而且加工中这个表层被快速的去除。从而传递给工件的热量较少,导致工件的磨削温度相当低。而对于长度较短的工件,可能达不到稳态条件,尤其在工作速度较低的情况下。This paper investigates the heat penetration indeep grinding. It is found that HEDG process leads to ashallower thermal penetration to workpiece, the grindingheat tends to concentrate at the contact layer with increasedwork speed and this layer is more quickly removed, resultingin lower energy partition to workpiece and possibly lowgrinding temperature. For short workpieces, steadyconditions may not be achieved, particularly at low workingspeed. Experimental results are presented for temperaturein high efficiency deep grinding.
