How to prevent deformation of stainless steel during wire cutting? Wire cutting machine source manufacturer [Zhikai CNC]

Stainless steel is a metal material with excellent corrosion resistance, which is often used to make various mechanical parts and decorations. During the wire cutting process of stainless steel, it is easy to cause the stainless steel to deform due to the heat and mechanical stress generated during the cutting process. In order to prevent the deformation of stainless steel wire cutting, the following measures can be taken:

1. Choose appropriate cutting parameters:

The selection of parameters such as cutting speed, cutting pressure and cutting depth is very important to prevent stainless steel from deformation. Generally speaking, a lower cutting speed and cutting pressure should be selected to reduce the impact of heat and mechanical stress on stainless steel. At the same time, the cutting depth should also be properly controlled to avoid excessive heat and stress concentration caused by cutting too deep at one time.

2. Develop a reasonable processing method

The nature of stainless steel determines that it has good hardness and corrosion resistance, but it is also easy to deform due to its high hardness. Therefore, when performing wire cutting, a reasonable processing method should be formulated according to the specific situation. An appropriate processing sequence can be used to disperse the processing and cutting points to avoid excessive heat focusing caused by concentrated positions and deformation. Some supporting materials can also be used to ensure that the stainless steel material can be better supported during processing to avoid vibration and deformation during processing.

3. Use coolant:

During the stainless steel wire cutting process, coolants can be used to reduce the temperature of the cutting area and reduce the impact of heat on the stainless steel. Commonly used coolants include water, oil and air. Choosing a suitable coolant can effectively reduce the temperature during the cutting process and reduce the deformation of the stainless steel.

4. Use preheating and post-heating treatment:

Before stainless steel wire cutting, the stainless steel can be preheated to make its temperature evenly distributed and reduce thermal stress during cutting. After cutting, the stainless steel can also be post-heat treated to gradually reduce its temperature and reduce residual stress, thereby reducing the deformation of the stainless steel.

5. Control the mechanical stress during cutting:

In the process of stainless steel wire cutting, mechanical stress is also an important factor causing stainless steel deformation. Therefore, the effect of mechanical stress should be minimized during the cutting process. Appropriate cutting methods, such as slow cutting and multiple cutting, can be used to reduce the concentration of mechanical stress.
In short, preventing the deformation of stainless steel wire cutting requires comprehensive consideration of factors such as cutting parameters, cutting tools, coolants, heat treatment and mechanical stress. By rationally selecting and controlling these factors, the deformation of stainless steel can be effectively reduced and the quality and efficiency of wire cutting can be improved.
