过去废刀体的回收是采用气焊的方法,将刀体上的坏刀片烧掉。这种方法不仅破坏了原刀槽的表面质量,而且重新加工刀槽时,常困残存硬质合金碎渣而损坏加工刃具。我们的后勤班全体同志遵照毛主席关于“中国应当对于人类有较大的贡献”的教导,在我厂开展的“三个一”活动中,成功地采用化学方法来回收废刀体及硬质合金刀片,为刀杆的修旧利废闯出了一条新路。
In the past, the recovery of scrap body is the use of gas welding method, the bad blade on the body burned. This method not only undermines the surface quality of the original sipe, but also re-machining the sipe, often trapped residual carbide damage and processing of cutting tools. In accordance with Chairman Mao’s teaching that “China should make a greater contribution to humankind,” all our comrades in our logistics group successfully used chemical methods to recycle scrap bodies and hard materials in the “Three Ones” activities carried out by our factory Alloy blades for the sharpening of the old repair scrapped a new road broke.
