一般來說，cnc加工比3D打印的肯定要貴些，但是這也是與這個行業的性質有關系的。做手板數量比較少的，機器調機，加工時間，打磨，表面處理這些都會影響后的，以cnc加工來說，會有以下要求，貴也是有理由的。下面濟南手板廠家為您分析！

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公差要求時，一般的國產設備都加工不了，希望購買昂貴的進口CNC加工，況且這樣的精度對操機人員的要求也非常高，沒有點真本事的操機師傅還真不能勝任，而這樣的師傅工資是非常高的

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手板模型加工的結構與尺寸大小

Structure and size of CNC prototype processing

若產品結構復雜，加工成本也會高許多；若產品整體尺寸很大或外觀是曲面形狀，加工成本也會上升許多。

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，需要經驗豐富的打磨師傅進行反復打磨，這里不得不提一下，其實打磨是件非常辛苦的事情：需要選用型號比較大的砂紙打磨，磨掉比較大的表面瑕疵；再用型號稍微小一點的砂紙進行打磨，直到用肉眼看不到一點瑕疵。比較費時間的就是打磨。

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.

后處理工藝

Post treatment process

手板模型的后處理工藝越多，自然也越高，噴漆，絲印，氧化，電鍍，鐳雕，沒有哪個表面處理工藝不需要花費大量的人工成本。

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.

塑料手板在市場中使用的很好，這是因為塑膠材質具有性價比高、易加工等優點，并且比較容易后處理，塑膠手板的性能也比較好，打磨之后可以直接在表面噴油漆，無需打底漆。

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.

從手板模型應用行業來看，現在不管是在醫療器械手板，還是家用電器手板，或者是汽車手板、辦公設備等大部分都是使用塑膠材料來做的，說明它的使用范圍是很廣泛的。

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.

除了使用的范圍廣，還是因為手板模型的使用壽命長，能夠展示出產品的優缺點，在研發和設計的時候都會關注很多細節，手板在使用的時候也都是較好的，可以重復檢驗設計。

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加工塑膠相對加工金屬來說，要快很多，打磨也簡單，塑膠的大型的零件還可以拆件加工，所以方面有一定的優勢。

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.

以上這些，可以很好的證明CNC手板模型加工的稍高一些是有理可循的，您了解了嗎？更多相關手板問題或者需求就來我們網站http://www.metferro.com進行咨詢吧！
