We are Lewei Precision specialized in the field of Wire EDM (Electrical Discharge Machining) to provide precision-engineered parts with unmatched precision. It is an advanced procedure that involves regulated electrical releases to make complex forms and contours in metal. The release is between two electrodes that are submerged in dielectric fluid, which is a precise and effective method of melting and vaporizing the material.
The peculiarity of Wire EDM is that it is capable of working with complex geometries and materials which are challenging to machine using old technology. It also works well on machining of heat-treated steels, superalloys and hard metals and is capable of producing tight tolerances and finer details, including small holes and narrow cut edges, and fine lines. Our services are ideal in those industries that require high precision such as in aerospace, automobile and mold making. Our technicians are those who combine the best of the state of the art technology with the use of the Wire EDM to make each part the best. Lewei Precision is a company that is certified ISO 9001:2015, ISO 13485 and IATF 16949, and it confirms our desire to focus on quality and accuracy in any project.
In Lewei Precision, we have the promise to provide parts of the highest quality. Advanced equipment like Coordinate Measuring Machines (CMM) are used to check the Dimensional Accuracy of our components to ensure that all components are made to your specifications. This accuracy is essential in any industry where reliability and accuracy are important e.g. aerospace, automotive and production of medical devices. With the help of the latest equipment, we ensure that every component is produced to fit to your exact specifications.
Alongside dimensional controls, we also do Tolerance Verification which is to make sure that every part meets the stringent requirements of ISO and ASME. We do not simply inspect our Surface and Finish Testing, and we carefully measure the surface finishes and the thicknesses of coating to guarantee the reliable and constant results. This overall quality control procedure enables us to produce parts of high surface integrity and uniform finish that gives you the quality parts to work on your projects.
机械加工
在线切割加工（放电加工）中，由计算机系统精确引导的细线穿过浸没在去离子水中的工件。作为导向和电极，线材利用受控放电高精度地切割导电材料，加工出的零件表面光洁度高，很少需要额外加工。乐威拥有最先进的设备，即使是最复杂的设计也能精确加工，这体现了我们对质量和客户满意度的承诺。
第一步是将工件牢固地固定在放电加工机床的工作台上，确保其完全静止不动。然后对工件表面进行仔细清洁和脱脂处理，以去除任何污染物。工件材料必须导电，因为线切割放电加工需要导电介质才能有效运行。
接下来，一根细金属线穿过机器的导轨，同时金属线和工件都浸没在电介质（通常是去离子水）中。施加电压后，介电液发生电离，从而产生放电（火花），逐渐侵蚀工件表面。
最后一步是使用计算机数控（CNC）系统精确控制线材的运动。数控系统引导金属丝沿着确定的路径运动，从而在工件上切割出复杂的形状和轮廓。在切割过程中，介电流体不断循环以清除碎屑并调节温度。切割完成后，提取工件，生产出高质量、精确的成品。
