一般来说，cnc加工比3D打印的肯定要贵些，但是这也是与这个行业的性质有关系的。做手板数量比较少的，机器调机，加工时间，打磨，表面处理这些都会影响后的，以cnc加工来说，会有以下要求，贵也是有理由的。下面济南手板厂家为您分析！

Generally speaking, CNC processing is certainly more expensive than 3D printing, but this is also related to the nature of the industry. The number of hand boards is relatively small. Machine adjustment, processing time, grinding, and surface treatment will affect the price. For CNC processing, there will be the following requirements, and there is a reason for the high price. The following Jinan prototype manufacturers will analyze for you!

CNC手板模型加工的精度

Machining accuracy of CNC hand model

若需要到0.01mm公差要求时，一般的国产设备都加工不了，希望购买昂贵的进口CNC加工，况且这样的精度对操机人员的要求也非常高，没有点真本事的操机师傅还真不能胜任，而这样的师傅工资是非常高的

If the tolerance of 0.01mm is required, ordinary domestic equipment cannot be processed. I hope to buy expensive imported CNC machining centers. Moreover, such accuracy requires very high requirements for the operator. The operator who has no real skills is really not competent, and the cost of such a master is very high

CNC手板模型加工的结构与尺寸大小

Structure and size of CNC prototype processing

若产品结构复杂，加工成本也会高许多；若产品整体尺寸很大或外观是曲面形状，加工成本也会上升许多。

If the product structure is complex, the processing cost will be much higher; If the overall size of the product is large or the appearance is curved, the processing cost will also rise a lot.

CNC手板模型加工的表面光滑程度

Surface smoothness of CNC hand model processing

如果手板表面要求打磨得非常光滑，需要经验丰富的打磨师傅进行反复打磨，这里不得不提一下，其实打磨是件非常辛苦的事情：需要选用型号比较大的砂纸打磨，磨掉比较大的表面瑕疵；再用型号稍微小一点的砂纸进行打磨，直到用肉眼看不到一点瑕疵。比较费时间的就是打磨。

If the surface of the hand board is required to be polished very smoothly, an experienced sander is required to polish it repeatedly. It has to be mentioned here that polishing is a very hard job: you need to use a larger model of sandpaper to polish it to remove larger surface defects; Then polish it with a slightly smaller sandpaper until no defect can be seen with the naked eye. Grinding is time-consuming.

后处理工艺

Post treatment process

手板模型的后处理工艺越多，自然也越高，喷漆，丝印，氧化，电镀，镭雕，没有哪个表面处理工艺不需要花费大量的人工成本。

The more post-treatment processes of the prototype, the higher the price will naturally be. No surface treatment process needs to spend a lot of labor costs, such as painting, silk screen printing, oxidation, electroplating, and radium carving.

塑料手板在市场中使用的很好，这是因为塑胶材质具有性价比高、易加工等优点，并且比较容易后处理，塑胶手板的性能也比较好，打磨之后可以直接在表面喷油漆，无需打底漆。

Plastic hand boards are well used in the market, because plastic materials have the advantages of high cost performance, easy processing, etc., and are relatively easy to post-treatment. The performance of plastic hand boards is also good. After polishing, you can directly spray paint on the surface without primer.

从手板模型应用行业来看，现在不管是在医疗器械手板，还是家用电器手板，或者是汽车手板、办公设备等大部分都是使用塑胶材料来做的，说明它的使用范围是很广泛的。

From the perspective of the prototype application industry, plastic materials are used for most of the medical device prototype, household appliance prototype, automobile prototype, office equipment, etc., which shows that it is widely used.

除了使用的范围广，还是因为手板模型的使用寿命长，能够展示出产品的优缺点，在研发和设计的时候都会关注很多细节，手板在使用的时候也都是较好的，可以重复检验设计。

In addition to the wide range of use, it is also because the prototype has a long service life, which can show the advantages and disadvantages of the product. During the research and development and design, attention will be paid to many details. The prototype is also good in use, and the design can be repeatedly inspected.

CNC加工塑胶相对加工金属来说，要快很多，打磨也简单，塑胶的大型的零件还可以拆件加工，所以方面有一定的优势。

CNC processing plastic is much faster than metal processing, and polishing is also simple. Large plastic parts can also be disassembled for processing, so the price has certain advantages.

以上这些，可以很好的证明CNC手板模型加工的稍高一些是有理可循的，您了解了吗？更多相关手板问题或者需求就来我们网站http://www.metferro.com进行咨询吧！
