ECM and AFM machining
We have more than ten years of experience in AFM technology (Abrasive flow machining). This efficient technology is ideal for polishing and deburring internal, often complex, internal shapes of a component. Typical uses are the channel surfaces of hydraulic manifold blocks.
ECM (electrochemical machining) technology helps to improve product geometry and to remove internal tensions. As a result, the parts tolerate higher pressures and last long.
While engine technology has become more ecological, the use pressures of fuel systems have increased. Higher pressures enable better efficiency, but they also burden the parts of the fuel line. For instance, aerospace and transportation widely use ECM technology in the component production of engines and fuel systems.
The finest thing about ECM technology is the way it handles the product’s intricate. It also brings new efficiency to the machining of external shapes, finishing every phase at the same time.
The electrochemical process enables accurate access to the product’s intricate shapes, making ECM machines efficient in producing high-precision surfaces. They serve the machining of both soft and chilled products. A tailored machining tool is needed for each product, so the technology is at best in serial production.
What is electrochemical machining?
The operation of an ECM (electrochemical machining) machine is based on a method where the workpiece surface is being finished using anodic metal dissolution. A machining tool serves as a cathode and creates an anodic reaction with the workpiece in the presence of electrolyte fluid. The process removes workpiece surface material in a precise and repeatable manner. The shape of the tool regulates the amount of material being removed and determines the final shape of the workpiece surface.
