A coupler, also called an adapter, is a device that transfers power between systems. It can divide one microwave power into several circuits in proportion in a microwave system; it can also connect the shafts of driving equipment and driven equipment in machinery. A coupler can be a self-contained hardware interface device that allows a hardware or electrical interface to be connected to another hardware or electrical interface. The CNC lathe processing coupler can design the 3D rendering of the coupler according to your drawings, and realize rapid prototyping. In addition, it can also meet the requirements of high-precision manufacturing technology.
