Sheet metal chassis processing is a general term for the processing methods of chassis and cabinets, which is the processing method for achieving chassis and cabinet products. The processing of sheet metal chassis not only requires the structural process of the chassis and cabinet, but also has strict requirements for the surface treatment of the product.

对于钣金机箱加工来说，产品的良好形象也是很重要的，这需要通过加工中的规范操作以及后期的表面处理来实现。

For the processing of sheet metal chassis, a good image of the product is also important, which needs to be achieved through standardized operations during processing and subsequent surface treatment.

钣金机箱加工中对各工序和部件的验收也是有标准的，一定要注意的几点：

There are also standards for the acceptance of various processes and components in the processing of sheet metal chassis. The following points must be noted:

1、钣金机柜不允许有肉眼可见倾斜或局部歪、扭现象存在。框架立柱与底座垂直度为小于1.5mm。检测时以底座上表面为基准，以立杆上端内沿面为测量点。

1. Sheet metal cabinets are not allowed to have visible tilting or local tilting or twisting. The verticality between the frame column and the base is less than 1.5mm. During the inspection, the upper surface of the base is used as the reference, and the inner edge surface of the upper end of the upright pole is used as the measurement point.

2、顶框与底座平行度为1小于1mm。监测点为底座上表面及顶框下表面，且互为基准。也可以通过测量六面之对角线的长度，相差不超过2.5mm来检测。有中隔板者，顶框与底座平行度可放宽1.5mm，中隔板与顶框或底座平行小于1mm。

2. The parallelism between the top frame and the base is less than 1mm. The monitoring points are the upper surface of the base and the lower surface of the top frame, and are mutually referenced. It can also be detected by measuring the length of the diagonal of the six sides, with a difference of no more than 2.5mm. For those with a middle partition, the parallelism between the top frame and the base can be relaxed to 1.5mm, and the parallelism between the middle partition and the top frame or base can be less than 1mm.

3、上、下围框的对角线之差的值小于1.5mm。

3. The absolute value of the difference between the diagonal lines of the upper and lower bounding boxes is less than 1.5mm.

4、立柱不能有扭曲现象，各立柱与上、下围框相连的两端交界线与围框相邻平面的平行度为小于0.5mm。

4. The columns should not be twisted, and the parallelism between the intersection lines of each column and the upper and lower bounding boxes and the adjacent planes of the bounding boxes should be less than 0.5mm.

5、支撑插箱的滑道，同一层的左、右滑道所组成的工作面相对于底座上表面的平行度为1mm，且应保证插箱装入后相邻两面板之间间隙之差的值不超过0.6mm。

5. The working surface composed of the left and right slides on the same layer supporting the plug-in box should have a parallelism of 1mm relative to the surface of the base, and the absolute difference in gap between adjacent panels after the plug-in box is installed should not exceed 0.6mm.

制作过程中的合规操作，给后期的表面处理带来了便利，不需要修修补补，通过喷漆或者喷塑处理就能实现良好的视觉效果，同时能有效的延长产品的使用寿命。

The compliant operation during the production process brings convenience to the surface treatment in the later stage, without the need for repair. By spraying paint or plastic, good visual effects can be achieved, and the service life of the product can be effectively extended.
