The force control is divided into two different ways: the general stiffness and the high stiffness. We first discuss the force loading control of a general rigid body. We know that by applying an external force to the object, the object will be deformed, and the relationship between them is proportional, and the greater the stiffness of the object, the smaller the deformation. Accurate displacement control is necessary to realize the precise load closed-loop control. 

The integrated digital hydraulic cylinder can realize the precision of micron level repeat positioning, so it can meet the requirements of the most accurate load control. Next, we discuss the force loading control of high stiffness. Digital hydraulic valve port can realize the linear resolution of 1/1000~1/10000 better than the servo valve, with the special design of the AEMETEC's flow pressure conversion system, you can achieve the high rigidity of the body force control precision.
