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

　　1、滾壓加工

　　1. Rolling processing

　　經(jīng)淬火和精磨后，可使用滾子或球在常溫下滾動(dòng)手板模型表面，使其發(fā)生塑性變形。軋制后，可以有效地改善手板模型表面的粗糙度。此外，冷硬層和殘余壓應(yīng)力也能有效提高其承載力和疲勞強(qiáng)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. 噴丸加工

　　2. Shot peening

　　它使用一個(gè)非常快的球擊中手板表面，使它看起來(lái)是一個(gè)冷硬層和殘余壓應(yīng)力。可顯著提高零件的疲勞強(qiáng)度和使用壽命。珠材可采用鑄鐵，關(guān)鍵絲也可采用。如果有些工件是由鋁加工而成，為了避免以上一些鐵顆粒導(dǎo)致的腐蝕問(wèn)題，非常好使用鋁球或玻璃球。這種加固工藝非常適用于某些碰撞復(fù)合材料，不能用于其它強(qiáng)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.鉆石拋光過(guò)程

　　3. Diamond polishing process

　　這是一種利用圓柱形或球形金剛石壓縮手模板的方法。通過(guò)這一工藝，可以有效的提高工件的表面質(zhì)量，提高生產(chǎn)效率，同時(shí)還可以使手板具有更好的疲勞強(qiáng)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.

　　不同的加工技術(shù)可以提高手板模型的性能。在加工過(guò)程中，根據(jù)手板的應(yīng)用和實(shí)際缺陷，可以找到更合適的方法。手板模型可以在各個(gè)方面得到有效的改進(jìn)。

　　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.
