科技日新月异，机械加工技术也在不断发展。现在，很多公司都利用CNC机床来生产塑料外壳，这样可以更好的满足客户的需求。下面就让我们来看看如何利用机械加工技术改造外壳。

　　1. if the product is relatively large, it is better to use the horizontal machining center to process the shell, so that the product can be made more accurately;

　　2. 如果产品较小，可以考虑使用数控铣床来加工外壳，这样可以减少生产成本；

　　2. If the product is relatively small, consider using the NC milling machine to process the shell, so as to reduce production costs;

　　3. 要想使外壳更耐磨，那么就可以考虑使用磨床来处理，这样可以增加产品的使用寿命；

　　3. If you want the shell to be more wear-resistant, you can consider using the grinder to deal with it, so as to increase the service life of the product;

　　4. 如果产品的外壳要求更高，那么可以使用激光加工来实现，这样可以使外壳更精致；

　　4. If the product shell requires higher, then you can use laser processing to achieve, so that the shell is more delicate;

　　5. 要想使外壳更耐磨损，那么就可以考虑使用热处理工艺来处理，这样可以使外壳更耐磨损。

　　5. If you want the shell to be more wear-resistant, you can consider using heat treatment technology to deal with it, so as to make the shell more wear-resistant.
