What is the main technique for cutting copper busbar flexible connectors? Is it wire cutting?Copper bus manufacturerTo tell you, it is wire EDM. This type of cutting uses a continuously moving thin metal wire (called an electrode wire) as the electrode to perform pulse spark discharge for removing metal and cutting into shape. It is mainly used for processing workpieces with complex shapes and precise small sizes, such as punches, dies, die sets, fixed plates, ejection plates, forming tools, templates, metal electrodes for EDM processing, various micro-holes, grooves, narrow slots, and arbitrary curves. It has prominent advantages such as small machining allowance, high machining accuracy, short production cycle, and low manufacturing cost.

It is precisely because it does not require mold development; as long as there are design drawings, computer numerical control can complete the cutting and hollowing of the product's casing. For thin sheets like Shenyang copper busbars, using wire cutting for drilling is very good.

The quality of copper busbar installation is very important for later use; here are the key points to pay attention to when installing copper busbars.

1. Gloves must be worn during copper busbar assembly to prevent fingerprints and stains from leaving on the surface.

2. Fasteners used for copper busbar connections should use galvanized bolts/screws, nuts, and washers that meet national standards.

3. The length of combined screws should be such that after tightening, 2–5mm of the thread protrudes beyond the nut. The length of hexagonal head bolts/round head square neck bolts should be such that after tightening, 5–8mm of the thread protrudes beyond the nut, and should not be too long or too short.

4. The general direction for the bolts to pass through is usually from bottom to top, from back to front, and from left to right, striving for uniformity. When the copper busbar is placed horizontally, the bolts and nuts for connection should be tightened from bottom to top; in other cases, the nuts should be installed on the side that is convenient for maintenance.

5. Both sides of the bolt connecting the T2 copper busbar must have flat washers, and the nut side should have a spring washer or lock washer. There should be a clear spacing of more than 3mm between the washers of adjacent bolts to prevent the formation of magnetic circuit heating.

6. Generally, it is not advisable to overlap three copper busbars at one place, specific requirements depend on the design and process documents.

7. The contact surface of the copper busbar should be connected tightly. The connecting bolts should be tightened with a torque wrench for confirmation and marked. The connecting combination screws should be tightened with a torque driver for confirmation and marked. The tightening torque value should comply with the provisions of the "Threaded Fastening Process Specification".

The copper busbar flexible connector uses wire cutting, which has many advantages and requires precise control, so its production cost is relatively high. However, it should be understood that the higher the precision, the better the product produced, and the quality is very good, including during use. Even during the production process at copper busbar manufacturers, it is necessary to maintain the cleanliness of the busbar surface and the standards of transportation into storage, so as to effectively ensure the quality of the busbar.
