The equipment chassis frame processing has extremely high specification requirements, and the components are matched with each other. The dimensional accuracy can reach millimeters, such as the following, it must meet the standard:

1. The bottom and other sides of the cabinet should be 1mm flat.

2. The verticality of each side of the chassis body relative to the bottom surface should be accurate to 1mm.

3. After the panel is installed in the chassis, it should be able to keep the vertical end in line with the dimensions inside the chassis, and keep the side and bottom surfaces perpendicular to the bottom of the cabinet by 0.5 mm.

4, the chassis shell and other components must be grabbed, the connection should not be loose, floating phenomenon; and the insertion and removal of each plug should be smooth, unobstructed, stagnation feeling.

5, the chassis should always be smooth, flat, no scratches or unevenness.

Dongguan equipment chassis processing describes that the formed sheet metal chassis can be widely used due to its excellent material properties. To sum up, it can be roughly divided into the following aspects:

1. The sheet metal case has good electrical conductivity. It can be used slightly to exert the effect of electromagnetic shielding. It can effectively eliminate the influence of external electromagnetic on the inside and achieve good protection.

2, the overall strength and light weight of the chassis, on the one hand to ensure its ruggedness, can withstand a certain external impact, not easy to deform, high security; on the other hand, it is more convenient to carry and install, use It is more convenient and has certain advantages in promoting application.

3. The production cost of the sheet metal chassis is low, and it can carry out large-scale production. This improves the economical cost performance of the sheet metal chassis, and also facilitates the mass production of the chassis, thereby obtaining more applications.

4, high-precision specifications size, due to the use of sheet metal processing technology, the precision of its components in the size of the busy millimeter, only greatly enhanced the safety and stability of its use.
