鈑金加工機箱機櫃時，我們(men) 都知道現在的客戶對機箱機櫃的要求很高，對於(yu) 外觀的要求也很嚴(yan) 格，其實這外觀不僅(jin) 僅(jin) 關(guan) 係到美觀的問題，它也直接的反應了產(chan) 品的質量，同時也對日後的使用有著很大的作用。對於(yu) 機箱機櫃外觀重要性不言而喻，為(wei) 了避免外觀影響產(chan) 品質量，在生產(chan) 製作時，一定要仔細，對於(yu) 外觀上有問題時，一定要及時的補救，甚是淘汰。

When sheet metal processing chassis and cabinets, we all know that customers nowadays have high requirements for chassis and cabinets, as well as strict requirements for appearance. In fact, this appearance is not only related to aesthetics, but also directly reflects the quality of the product, and also has a great impact on future use. The importance of the appearance of the chassis and cabinet is self-evident. In order to avoid the impact of appearance on product quality, careful production is necessary. If there are any problems with the appearance, timely remedies or even elimination are necessary.

方法/步驟

Method/Steps

下料：下料方式有各種，主要有以下幾種方式

Cutting: There are various cutting methods, mainly including the following

①. 剪床：是利用剪床剪切條料簡單料件，它主要是為(wei) 模具落料成形準備加工，成本低，精度低於(yu) 0.2，但隻能加工無孔無切角的條料或塊料。

①.  Scissor bed: It is a machine that uses a shearing machine to cut simple pieces of material. It is mainly used for preparing and processing the mold for material cutting and forming, with low cost and accuracy below 0.2. However, it can only process strip or block materials without holes or cutting corners.

②. 衝(chong) 床：是利用衝(chong) 床分一步或多步在板材上將零件展開後的平板件衝(chong) 裁成形各種形狀料件，其優(you) 點是耗費工時短，效率高，精度高，成本低，適用大批量生產(chan) ，但要設計模具。

②.  Punching machine: It is a type of machine that uses a punching machine to unfold parts in one or more steps on a sheet metal to form various shaped parts. Its advantages include short working hours, high efficiency, high accuracy, low cost, and suitability for mass production, but mold design is required.

③. NC數控下料，NC下料時要編寫(xie) 數控加工程式，利用編程軟件，將繪製的展開圖編寫(xie) 成NC數拉加工機床可識別的程式，讓其根據這些程式一步一刀在平板上衝(chong) 裁各構形狀平板件，但其結構 受刀具結構所，成本低，精度於(yu) 0.15。

③.  NC numerical control cutting, when NC cutting, the first step is to write a numerical control machining program. Using programming software, the unfolded diagram is written into a program that can be recognized by the NC numerical drawing machine tool. Based on these programs, each structure of the flat part is punched step by step on the flat plate. However, its structure is affected by the tool structure, and the cost is low, with an accuracy of 0.15.

④. 鐳射下料，是利用激光切割方式，在大平板上將其平板的結構形狀切割出來，同NC下料一樣需編寫(xie) 鐳射程式，它可下各種複雜形狀的平板件，成本高，精度於(yu) 0.1。

④.  Laser cutting is the use of laser cutting methods to cut the structural shape of a large flat plate. Similar to NC cutting, laser programs need to be written. It can cut various complex shaped flat pieces with high cost and accuracy of 0.1.

⑤. 鋸床：主要用下鋁型材、方管、圖管、圓棒料之類，成本低，精度低。

⑤.  Sawing machine: mainly used for aluminum profiles, square tubes, drawing tubes, round bar materials, etc., with low cost and low accuracy.

鈑金加工機箱機櫃是要注意：1、機箱機櫃表麵的塗層一定要均勻，無流掛、露底現象。2、標識要齊全、清晰，並且耐久可靠，標注序號不可缺失。3、機箱機櫃的每個(ge) 麵板都要平整，沒有扭曲、變形的現象，櫃門上的開孔要均勻、整齊。4、尺寸要符合要求，誤差不可過大。 機箱機櫃品質差異所存在的差異因素，機箱機櫃由於(yu) 廠家的工藝不同，材質選用不同，在加上市場的需求不同，其品質也是千差萬(wan) 別，因為(wei) 不同層次的需求，機箱機櫃也體(ti) 現出了不同的類型，但是無論差多少，都是有原因的。鈑金加工機箱機櫃的品質不同，那個(ge) 層次的產(chan) 品都存在市場中，通常技術人員在選料時，並不一定是看中，它隻是其中的一部分原因，非全部，對於(yu) 技術人員而言，他們(men) 更看重的是材料本身是否達標，對於(yu) 機箱機櫃的製作，一般是選用鋼製材料，這種材質因為(wei) 特殊的原因也有可能生鏽，在選購物料多時，也許並不能一個(ge) 個(ge) 檢查過來，可能在這些生產(chan) 材料當中夾雜著一些有瑕疵的原料。

Attention should be paid to sheet metal processing of chassis and cabinets: 1. The coating on the surface of the chassis and cabinets must be uniform, without any sagging or exposed bottom. 2. The identification should be complete, clear, durable and reliable, and the serial number should not be missing. 3. Each panel of the chassis cabinet should be flat, without any distortion or deformation, and the openings on the cabinet door should be even and neat. 4. The size should meet the requirements and the error should not be too large. The differences in the quality of chassis and cabinets are due to the different manufacturing processes and material choices of manufacturers, as well as the varying market demands. As a result, the quality of chassis and cabinets varies greatly. Different levels of demand reflect different types of chassis and cabinets, but no matter how much difference, there is a reason for it. The quality of sheet metal processing chassis and cabinets varies, and products at that level exist in the market. Usually, technicians do not necessarily value the price when selecting materials. It is only a part of the reason, not the whole. For technicians, they value more whether the materials themselves meet the standards. For the production of chassis and cabinets, steel materials are generally used, which may rust due to special reasons. When selecting a large number of materials, it may not be possible to inspect them one by one, and there may be some defective raw materials mixed in these production materials.
