热压板是热压机的一个主要部件,在其纵向及横向需钻削孔道,以形成热介质回路。孔的长径比往往超过90,难以加工。通常热压扳采用A_3号钢制造,钻孔时断屑困难,不便于排除切屑,因此,合理地设计深孔加工方法,对于提高深孔加工质量与效率是十分重要的。一、各深孔加工系统在热压板加工中的应用 Hot plate is a main part of hot press, in its vertical and horizontal drilling holes to be drilled to form a heat medium circuit. The aspect ratio of the hole is often more than 90, it is difficult to process. Usually hot plate pull made of A_3 steel, drilling chip breaking difficulties, not easy to rule out the chip, therefore, a reasonable design of deep hole processing method for improving the quality and efficiency of deep hole processing is very important. First, the deep hole processing system in the hot plate processing applications
