How to adjust the current of medium wire cutting? [Zhikai CNC professional answer]
Medium wire cutting is a common metal cutting method that applies high-frequency current to the workpiece, allowing the current to pass through the molybdenum wire to generate heat, thereby cutting the workpiece into the desired shape. Adjusting the current of medium wire cutting can affect aspects such as cutting speed, cutting quality, and cutting cost. The following will introduce how to adjust the current of medium wire cutting.
1. Understand the workpiece material and thickness: Different metal materials and thicknesses have different requirements for the current of medium wire cutting. Generally speaking, materials with higher hardness require higher currents, while thinner materials require lower currents. Therefore, before adjusting the current, you must first understand the material and thickness of the workpiece.
2. Consider cutting speed and quality: The current of medium wire cutting is closely related to cutting speed and quality. Higher current can increase cutting speed, but may affect cutting quality, such as producing larger slag and larger cutting width. Lower current can improve cutting quality, but will reduce cutting speed. Therefore, when adjusting the current, it is necessary to comprehensively consider the requirements of cutting speed and quality. Zhikai's exclusive slow-wire stripping power supply technology - Zhikai's unobstructed electrolytic high-frequency power supply (national copyright number: 2018SR156739), Zhikai's electrolytic high frequency, inhibits electrolytic corrosion and improves surface quality. When special materials are processed without electrolysis, the surface is not easy to oxidize and discolor, such as when special alloys are processed, primary color cutting is achieved.
3. Adjust according to empirical parameters: The current adjustment of medium-wire wire cutting can refer to empirical parameters. Different equipment and cutting conditions may have different empirical parameters, which can be obtained by consulting equipment manufacturers or other experienced operators. Make preliminary adjustments based on empirical parameters, and then make fine adjustments based on actual conditions.
4. Conduct a trial cutting experiment: In order to determine the best cutting current, a trial cutting experiment can be conducted. Select a piece of material similar to the actual workpiece, and gradually adjust the current for trial cutting according to the preset cutting speed and quality requirements. Observe the cutting effect, including cutting speed, cutting quality, and cutting width. According to the trial cutting results, gradually adjust the current until the best cutting effect is achieved.
5. Pay attention to safety issues: When adjusting the current of medium-wire wire cutting, you need to pay attention to safety issues. High-frequency current is dangerous, so operators should wear protective equipment to ensure a safe operating environment. In addition, you should also pay attention to the current limit of the equipment and do not exceed the rated current range of the equipment.
In short, when adjusting the current of wire cutting, factors such as workpiece material and thickness, cutting speed and quality requirements need to be considered. You can refer to the empirical parameters for preliminary adjustment, and then conduct trial cutting experiments to finally determine the optimal cutting current. When adjusting the current, you need to pay attention to safety issues to ensure a safe operating environment.
