Wire cutting processing is a special processing technology widely used in mold manufacturing, precision part processing, and other fields, especially suitable for cutting complex shapes of hard materials. The processing precision directly affects the quality and performance of the final product. Therefore, how to effectively improve the precision of wire cutting processing has become a key issue of concern for technical personnel.



Firstly, choosing the appropriate equipment is the foundation for improving processing precision. High-precision CNC wire cutting machines equipped with advanced control systems and stable mechanical structures can effectively reduce the source of error. In addition, factors such as machine rigidity, guide rail precision, and screw clearance directly affect the stability of processing. Therefore, when purchasing equipment, it is advisable to prioritize models with high precision and good stability.



Secondly, optimizing processing parameters is crucial for improving precision. Discharge parameters during wire cutting processing, such as pulse width, pulse interval, and discharge current, all affect the surface quality and dimensional accuracy of the processing. Reasonably setting these parameters can reduce the heat affected area during discharge, prevent material deformation. At the same time, the wire feeding speed and tension should also be adjusted according to the material characteristics to ensure the stability of molybdenum wire operation, thereby improving cutting precision.



Thirdly, material pretreatment is also an indispensable link. Before wire cutting, appropriate heat treatment should be carried out on the workpiece to eliminate internal stress and avoid deformation during processing due to stress release. In addition, the workpiece clamping should be firm and uniform to avoid offset or vibration caused by improper clamping, which affects processing precision.



Moreover, using high-quality electrode wires (such as galvanized wire, brass wire, etc.) and pure deionized water as the working fluid can significantly improve the stability and surface quality of cutting. The quality of the electrode wire directly affects the discharge efficiency and cutting speed, while deionized water helps to remove chips in time, cool the workpiece, and maintain the cleanliness and stability of the processing area.



Finally, the experience and operation level of technical personnel are also important factors affecting processing precision. Skilled operators can accurately judge the processing status, adjust parameters in time, and avoid abnormal situations during processing, such as breaking of wires and short circuits.



In summary, to improve the precision of wire cutting processing, it is necessary to start from multiple aspects such as equipment selection, parameter optimization, material pretreatment, selection of processing medium, and personnel quality. Only by implementing fine management and control at each link can high-precision wire cutting processing be truly realized, meeting the increasingly growing demand for precision parts in modern manufacturing.
