What are the advantages and disadvantages of wire cutting? [Zhikai CNC]

Wire cutting is a commonly used metal processing method that uses high-speed electric spark discharge to cut the workpiece into the desired shape. Wire cutting has some advantages and disadvantages, which are briefly described below.
Advantages:

1. High precision:

Wire cutting has high processing accuracy, which makes it very suitable for workpiece processing that requires high precision, such as mold manufacturing, precision parts processing, etc.

2. High precision:

Wire cutting can cut very small holes and details, which makes it very suitable for processing workpieces with complex shapes, such as thin plates, small parts, etc.

3. Fast cutting speed:

The cutting speed of wire cutting is relatively fast, and large-scale processing tasks can be completed quickly. This makes wire cutting very suitable for industries that require high-efficiency production, such as automotive manufacturing, aerospace, etc.

4. High cutting surface finish:

The surface finish of the wire cutting process is very high, which can reach the requirement of Ra0.8μm. This makes the surface quality of the workpiece processed by wire cutting very good, and no secondary processing is required, saving time and cost.

5. Wide application scope:

Wire cutting is suitable for various metal materials, such as steel, aluminum, copper, titanium, etc. Whether it is a hard material or a soft material, wire cutting can be competent.

shortcoming:

1. The cutting speed is relatively slow:

Although the cutting speed of wire cutting is relatively fast, it is still slow compared with other processing methods. This makes wire cutting unsuitable for processing large quantities of workpieces, such as large structural parts.

2. Limited cutting thickness:

The cutting thickness of wire cutting is limited to a certain extent, usually within 300mm. For workpieces exceeding this thickness, wire cutting will not produce good results.

3. There is a heat-affected zone on the cutting surface:

The wire cutting process generates high temperatures, resulting in a certain heat-affected zone around the cutting surface. This may have a certain impact on the performance of the workpiece and require subsequent treatment.

4. Limited cutting accuracy:

Although wire cutting has high machining accuracy, the cutting accuracy may be limited due to factors such as molybdenum wire wear and workpiece deformation during machining. Suzhou Zhikai CNC Technology Co., Ltd. independently develops a high-frequency pulse power supply with low molybdenum wire loss. Under normal machine tool conditions, it can effectively cut 200,000-300,000 square wires (18-17 wires).

5. High equipment and maintenance costs:

The equipment and maintenance costs required for wire cutting are relatively high, and special equipment and technicians are required for operation and maintenance. This increases the cost of wire cutting.
In summary, wire cutting has the advantages of high precision, high fineness, fast cutting speed, high cutting surface finish, and wide application range, but it also has disadvantages such as relatively slow cutting speed, limited cutting thickness, heat-affected zone on the cutting surface, limited cutting accuracy, and high equipment and maintenance costs. In practical applications, it is necessary to select the appropriate processing method according to the specific processing requirements and workpiece characteristics.
