Servo press fitting system (referred to as: servo press, commonly known in the market: servo press, servo press in system, servo press) is a CNC press fitting unit integrating assembly and measurement, and is the core component to realize "digital assembly". The modular servo control system is adopted to realize the real-time acquisition and analysis of force, displacement and time data, and to effectively monitor the force and displacement, force and time in the assembly process. It is suitable for all occasions with strict requirements for press fit process, such as high beat and high precision assembly applications such as press fit, forming, riveting, stamping and elastic test.
