手板模型加工的補救方法！
來源：http://www.letaocp.com作者：山東嘉瑞杰機械科技有限公司發布時間：2021-10-20
手板模型加工中我們應盡量避免出錯，但是在我們定制加工行業里面，要想不出錯也是不可能的，那么出錯后我們應該如何補救呢？一般可用補救材料填在過切或錯切的地方。在手板行業中常用的補救材料是原子灰或502膠水混合痱子粉。
We should try our best to avoid making mistakes in the processing of handboard models, but in our customized processing industry, it is impossible to make no mistakes, so how should we remedy the mistakes? Generally, remedial materials can be used to fill over cut or wrong cut places. The commonly used remedial material in the hand board industry is atomic ash or 502 glue mixed prickly heat powder.
原子灰為膠狀粘稠物，需要配合催干劑才能凝固。進口原子灰價格較貴，如：德國Bentex-autodody-filler，價格為100多/250克；國產原子灰價格較便宜，價格為50多/850克。
Atomic ash is a colloidal viscous substance, which needs to be combined with a drying agent to solidify. Imported atomic ash is expensive, such as bentex autodody filler in Germany, with a price of more than 100 / 250g; Domestic atomic ash is cheaper, with a price of more than 50 / 850 G.
502膠水混合痱子粉：取適量痱子粉加入502膠水調成稀糊狀即可。將調好的材料填入過切的地方待干后再補加工一下。
502 glue mixed with prickly heat powder: take an appropriate amount of prickly heat powder and add 502 glue to make it into a thin paste. Fill the adjusted material into the over cut place and process it again after it is dry.
補救前提是：工件為非透明件，透明工件是不許有粘接痕跡的。一般都是針對塑膠件進行補救，非透明件有：ABS，POM，PA。透明件有：PMMA，PC。
The premise of remedy is: the workpiece is non transparent, and the transparent workpiece is not allowed to have bonding traces. Generally, plastic parts are remedied. Non transparent parts include ABS, POM and PA. Transparent parts: PMMA, PC.
尤其是PMMA也是我們俗稱的有機玻璃，因為材料性能的特殊性，很脆易裂，又不能有粘接痕跡，所以在加工過程中要特別注意，一旦下刀過快，整個材料有可能會斷裂，那么整個手板就報廢，因此PMMA手板樣件也是較其他手板較貴的。
In particular, PMMA is also commonly known as plexiglass. Due to the particularity of material properties, it is very brittle and easy to crack, and there can be no bonding traces. Therefore, special attention should be paid in the processing process. Once the cutting is too fast, the whole material may break, and the whole hand board will be scrapped. Therefore, PMMA hand board samples are also more expensive than other hand boards.
