Small batch parts and prototype parts made of aluminum alloy, such as car swing arm, car elevation, new energy vehicle battery pack, electronic injector, medical precision hardware, radiator, energy storage equipment, photovoltaic panels and other precision parts, from prototype, small batch trial processing to custom production in the research and development process, CNC machining methods are invariably used. The machine has three-axis, four-axis and five-axis linkage models, processing machine models and processing methods mainly depend on the complexity of the drawings provided by the customers in the processing process.
