Mechanical Processing and Installation Sequence and Procedures

Issues to note in the detailed sequence of mechanical machining installation:

1. When arranging the sequence of detailed machining operations, it is essential to follow the basic principles of “surface first, then holes” and “roughing before finishing.”

2. Once the tool change point and the tool reference point have been determined, they should not be changed.

3. For hole systems with high coaxiality requirements, all holes in that system should be machined in one single setup before proceeding to machine hole systems at other coordinate locations. This approach eliminates the errors introduced by repeated setups and improves the coaxiality of the hole system.

4. Processing according to tool-concentrated procedures can effectively avoid reusing the same tool, thereby reducing the number and time required for tool changes.

High-precision components are used in testing equipment and instruments across various industries; domestically, they are primarily employed in the instrumentation and metering industry.

Compared to general mechanical manufacturing, mechanical manufacturing features higher product technology content (in both design and production), superior processing equipment, higher added value, and sales that typically exhibit characteristics of small-batch differentiation.

Stainless steel materials used for machining mechanical parts:

1. The material should have a moderate hardness—being at least one grade lower than that of the mechanical components. At the same time, it’s important to select the right material based on the intended function of the machined part.

2. Regarding the material hardness requirements, in some applications, the higher the material hardness, the better—but this applies only to the hardness requirements of the machined parts themselves. The material being processed must not be too hard; if it’s harder than the machined part itself, it simply cannot be processed.
