我厂根据苏联萨拉夫斯基切齿厂新工艺采用了铸铁刀杆铸焊硬质合金车刀。铸焊的方法是把硬质合金刀片放在刀体的砂型里,浇入铁水铸造出刀具来。这种方法做起来很简单。它不仅节约了优质中炭钢材,还可以省去锻、刨、铣等加工工序和焊接过程,大大地降低了车刀的成本。我们所采用的铸焊工艺如下:(1)硬质合金刀片的准备——刀片放入砂型之前,不须经过预热,但要 I plant under the new process of the Soviet Union Salavski cutting teeth using a cast iron tool cast carbide carboring knife. Casting welding method is the carbide blade on the body of the sand mold, pouring molten iron to cast the tool. This method is easy to do. It not only saves high-quality carbon steel, but also eliminates forging, planing, milling and other processing processes and welding processes, greatly reducing the cost of turning tools. We use the casting process is as follows: (1) Preparation of carbide inserts - blade into the sand before, without preheating, but to
