一般包括：
7.1.1 mechanical and electrical repair of combining
7.1.1 机械修理与电气改造相结合
Generally speaking, the need for a transformation of the electrical machine, are subject to mechanical repairs. Repairs to determine the requirements, scope, content must be decided by electrical machinery required to transform the structure of the request; transformation to determine electrical and mechanical repair, alteration between the staggered time requirements. The mechanical properties of intact electrical transform the basis of success.
一般来说，需进行电气改造的机床，都需进行机械修理。要确定修理的要求、范围、内容；也要确定因电气改造而需进行机械结构改造的要求t内容；还要确定电气改造与机械修理、改造之间的交错时间要求。机械性能的完好是电气改造成功的基础。
7.1.2 easy first, and to the overall situation after the first local
7.1.2 先易后难、先局部后全局
The removal of the original system must control the original drawings, carefully, to make drawings in a timely manner marked to prevent the demolition or omission (of local circumstances). In the process of demolition will discover some new system design in the gaps, and that should be promptly added, removed and parts of the system should be disaggregated, safekeeping, in case of failure or partial failure reinstated. There is a definite value, and can be used for spare parts for other machines. Must not extravagantly used and misplaced.
原系统的拆除必须对照原图纸，仔细进行，及时在图纸上作出标记，防止遗漏或过拆(局部改造情况下)。在拆的过程中也会发现一些新系统设计中的欠缺之处，应及时补充与修正，拆下的系统及零件应分门别类，妥善保管，以备万一改造不成功或局部失败时恢复使用。还有一定使用价值的，可作其他机床备件用。切忌大手大脚，乱扔乱放。
7.2 reasonable arrangements for a new location and routing system
7.2 合理安排新系统位置及布线
Under the new system design drawings and reasonable new system configurations, including fixed box, panel installation, alignments, and the fixed position adjustment components, sealing and necessary, such as decoration. Connection must be a clear division of work, it was reviewed inspection to ensure connectivity of norms, diameter appropriate, accurate, reliable handsome.
根据新系统设计图纸，合理进行新系统配置，包括箱体固定、面板安放、线路走向和固定、调整元器件位置、密封及必要装饰等。连线工作必须分工明确，有人复查检验，以确保连线工艺规范、线径合适、正确无误、可靠美观。
