Why use finishing in processing? (Metal parts)

In CNC manufacturing projects, finishing usually occurs after the roughing operation of the workpiece and is used to achieve the final dimensions in terms of flatness, thickness, roughness, tolerance and surface finish by removing any necessary excess material and finishing the manufactured component.

Finishing is a key part (Metal parts) of the manufacturing process. Here are the key considerations to be aware of before you get started:
1. Desired finish quality
It is important to remember that adding finishes to manufactured parts may have an impact on them in terms of GD&T and dimension. For example, applying powder paint to metal parts can cause their surface thickness to increase. Therefore, it is crucial to analyze the factors beforehand to ensure that the accuracy and precision of the machining will not be affected when the finishing is added.

2. Partial application
To choose the right finishing operation, you must consider the application of metal parts and the potential conditions it will be subjected to. For example, when dealing with hidden parts(Metal parts) used in vehicles, the finishing process will focus more on improving durability than aesthetics.

3. Processing cost
In addition to the above factors, the total costs associated with the completion of the project must also be considered. Quality finishes usually require quality materials, tools and sophisticated techniques. Therefore, it is critical to evaluate all of these cost variables in conjunction with your manufacturing project before choosing a finishing method.
