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.
Trabalhos de maquinagem
Na maquinação por EDM de fio (Descarga Eléctrica de Fio), um fio fino, guiado com precisão por sistemas informáticos, passa através de uma peça de trabalho submersa em água desionizada. Actuando como guia e elétrodo, o fio utiliza descargas eléctricas controladas para cortar materiais condutores com elevada precisão, produzindo peças com superfícies finamente acabadas que raramente necessitam de processamento adicional. As instalações de última geração da Lewei garantem que mesmo os projectos mais complexos são maquinados com precisão, demonstrando o nosso compromisso com a qualidade e a satisfação do cliente.
O primeiro passo consiste em fixar firmemente a peça de trabalho na mesa de trabalho da máquina EDM, certificando-se de que fica completamente imóvel. De seguida, a superfície é cuidadosamente limpa e desengordurada para eliminar quaisquer contaminantes. É essencial que o material da peça de trabalho seja condutor, uma vez que a electroerosão por fio depende de um meio condutor para funcionar eficazmente.
Em seguida, um fio metálico fino é passado através das guias da máquina, enquanto o fio e a peça de trabalho são submersos num fluido dielétrico, normalmente água desionizada. É aplicada uma tensão eléctrica que provoca a ionização do fluido e permite a ocorrência de uma descarga eléctrica (faísca), corroendo gradualmente a superfície da peça de trabalho.
O passo final consiste em controlar com precisão o movimento do fio através de um sistema de controlo numérico computorizado (CNC). O CNC dirige o fio ao longo de um caminho definido, permitindo-lhe cortar formas e perfis complexos na peça de trabalho. O fluido dielétrico circula continuamente para limpar os detritos e regular a temperatura durante o corte. Após a conclusão, a peça de trabalho é extraída, produzindo uma peça de alta qualidade e com acabamento preciso.
Os serviços de EDM de fio da Lewei Precision maquinam com precisão uma variedade de materiais condutores, incluindo aços endurecidos e superligas, fornecendo componentes precisos e duradouros para aplicações críticas.
Ideal for hardened tools, dies, and precision components with complex geometries.
