When the surface of the hand board model is strengthened, there are mainly the following processes.

　　1、滚压加工

　　1. Rolling processing

　　经淬火和精磨后，可使用滚子或球在常温下滚动手板模型表面，使其发生塑性变形。轧制后，可以有效地改善手板模型表面的粗糙度。此外，冷硬层和残余压应力也能有效提高其承载力和疲劳强度。

　　After quenching and fine grinding, the roller or ball can be used to roll the surface of the handboard model at room temperature to make it plastic deformation. After rolling, the surface roughness of the hand plate model can be effectively improved. In addition, the bearing capacity and fatigue strength of the cold hard layer and residual compressive stress can also be effectively improved.

　　2. 喷丸加工

　　2. Shot peening

　　它使用一个非常快的球击中手板表面，使它看起来是一个冷硬层和残余压应力。可显著提高零件的疲劳强度和使用寿命。珠材可采用铸铁，关键丝也可采用。如果有些工件是由铝加工而成，为了避免以上一些铁颗粒导致的腐蚀问题，使用铝球或玻璃球。这种加固工艺特别适用于某些碰撞复合材料，不能用于其它强夯方法。

　　It uses a very fast ball to hit the surface of the handboard, making it look like a hard layer and residual compressive stress. It can significantly improve the fatigue strength and service life of parts. The bead material can be cast iron, and the key wire can also be used. If some workpieces are made of aluminum, in order to avoid the corrosion problems caused by the above iron particles, it is better to use aluminum ball or glass ball. This strengthening technology is especially suitable for some impact composite materials and can not be used for other dynamic compaction methods.

　　3.钻石抛光过程

　　3. Diamond polishing process

　　这是一种利用圆柱形或球形金刚石压缩手模板的方法。通过这一工艺，可以有效的提高工件的表面质量，提高生产效率，同时还可以使手板具有更好的疲劳强度。

　　This is a method of compressing hand template with cylindrical or spherical diamond. Through this process, the surface quality of the workpiece can be effectively improved, the production efficiency can be improved, and the hand plate can also have better fatigue strength.

　　不同的加工技术可以提高手板模型的性能。在加工过程中，根据手板的应用和实际缺陷，可以找到更合适的方法。手板模型可以在各个方面得到有效的改进。

　　Different processing technologies can improve the performance of the hand board model. In the process of processing, according to the application and actual defects of handboards, we can find more suitable methods. Hand board model can be effectively improved in all aspects.
