The surface mackerel is a processing method that cuts out the corners (edges) of the parts. The chamfer can be categorized as "C -surface", which is mainly cut off at 45 degrees, the minimum "burr -removing" that drops the corners and squids, and the "R -surface" that makes it round and smooth. In this article, we will explain the type of chamfering processing and the points you want to keep at the time of chamfering.
When performing a chamfering, it is important to select a chamfer shape according to the application, in addition to the selection of tools that takes into account the chamfering.
When choosing a tool, it is important to consider the surface. It is necessary to consider "Is there enough space to approach the processing part", "Is there enough space to approach the processing part?"
When choosing a type of blade, it is necessary to consider whether the surface is taken or the back side. The types of tools include a blade replacement type and a fixed type (solid type), but for various types of chamfer, the blade replacement type is ideal. By replacing the edge of the blade according to the situation, it is possible to respond flexibly.
If the approach to the surface is narrow, you need to consider how to approach. By using a thin diameter tool, it is possible to perform the surface as expected, but it is important to note that if the tool diameter is thin, vibration is likely to occur and the strength may be insufficient.
The surface shape can be classified into three types: "C surface", "thread surface removal", and "R surface", and it is necessary to select a surface shape according to the application. I will explain the characteristics of each chamfer shape.
C -chah is the most common method. When simply represented as a surface, it often refers to C surface. It is a processing method that creates a 45 -degree surface on the corner. For example, if it is described as C0.5, it is necessary to cut the cutting with a width of 0.5 mm from the tip. In C -chamon, it is common to select a 45 -degree angle of the tool so that 45 degrees can be achieved efficiently.
Threading is the simplest method among three types of chamfering methods. It is a minimum processing method that removes burrs and squids that occurred during processing, and is characterized by low processing costs because the accuracy required of other chambers is not higher.
R -surface is a smooth chamfer with a rounded corner. Compared to other chamfers, it feels good to eliminate the corners completely, and there are many situations where R surface is required for exterior parts of consumer products. On the other hand, high quality is required, and the processing difficulty is the highest among three types of chamfer, so the processing cost is high.
In general, the surface is instructed in the drawing. Even if there is no instruction on the chamfer, it is desirable to remove the edge. If Burror squid remains, the lack of threading may lead to injury in the post -process. The surface is also effective for the interaction of parts in addition to safety. In particular, when holes are processed, it is necessary to take the surface of the hole in the entrance. By chamfering, you can smoothly insert parts.
In this article, we explain the type of chamfering process and the points you want to keep at the time of chamfering. Although it is a chamfer often seen in drawing instructions, selecting an appropriate chamfer after grasping the purpose of processing will lead to high value -added processing.
