建筑机械修复件终加工工艺(以下简称终加工工艺)是修复工艺的最后工序。它的成败直接影响修复件的质量,据苏《有前途的零件修复法和强化法》一书介绍,由于终加工工艺失误而产生的修复件缺陷占修复件缺陷总数的15.7%。另外,终加工工艺的经济性也直接影响修复成本。所以,它是修复工艺中重要的一环。它的经验还可作为加工新零件借鉴。一、终加工工艺的作用终加工工艺的作用如下:1.使修复件达到规定的几何形状和尺寸。2.使修复件的精度和粗糙度达到规定的级别。3.使修复件的强度、耐磨性等机械性能达到或超过新件标准。
Construction machinery repair parts finishing process (hereinafter referred to as the final processing) is the final process of repair process. Its success or failure has a direct impact on the quality of repair parts. According to Su, entitled “Promising Parts Repair and Reinforcement”, a total of 15.7% of the total number of repair defects were repaired due to final processing errors. In addition, the economics of final processing also have a direct impact on repair costs. So, it is an important part of the repair process. Its experience can also be used as a reference for processing new parts. First, the role of the final processing technology The role of the final processing technology is as follows: 1 to make the repair parts to the required geometry and size. 2. Make the accuracy and roughness of the restoration reach the specified level. 3. Repair parts of the strength, wear resistance and other mechanical properties meet or exceed the new standard.
