The drawing and die hardness required for guide pillar guide machining
Mar 24, 2018

In the work of production, in order to ensure the quality of the guide pillar guide products, it is necessary to have a reasonably designed drawing. This is because when the actual processing is performed, the guide column guide bush needs to be processed according to the data in the drawings.

 

Not only that, the drawing also has a very important role, that is to ensure the accuracy of the guide pillar guide processing.

In the current era of personalization, we try to meet the requirements of every customer as far as possible, and strictly follow the drawings and design requirements for processing and production.

 

So, in the process of processing, the hardness of the mold guide column to choose how much more appropriate? In order to ensure normal use, the hardness is generally not maximized during the heat treatment of the raw material. Each material or each type of mold fitting has a suitable hardness in use.

 

This is because each product in the actual application, not only the working environment is different, but also there are certain differences in the use requirements and work conditions. Mold guide posts are usually made of imported SUJ2 material. This SUJ2 high-carbon chromium bearing steel material can be hard-treated, hardness up to HRC58-61, general hardness is HRC58.

 

The reason why this type of material was chosen for the production of the guide column guide sleeve is not only because SUJ2 has the wear resistance of the bearing, but also its rigidity is excellent, and it has excellent processing performance, can be directly processed and molded, and the use of molds It is 2-3 times higher than the full hardware of SKD-61 (HRC52). The size changes little during quenching and tempering, and the fatigue resistance is quite good.

 

In general, the properties of the material, the treatment method and the processing requirements should be taken into account when selecting the hardness of the guide column. This is because the hardness of the guide pillar is affected by these three factors at the same time, and the three influence each other.
