Traditional industrial robots through accurate position control, according to the path in the space of robot control system planning movement, complete and handling, testing, painting, traditional materials such as homework. With the speeding up of the process of industrial automation, industrial application of robot in field more and more, in the face of the need to interact with the environmental effect of application scenarios, position control of the robot is pure and showed the limitation of the application. Insistance technology with years of experience in automatic polishing solution of constant force grinding research and development, provide enterprises with high precision, high flexible Force Control System, help enterprises to solve the demand of flexible polishing. The Force control system of flexible control, is the direction of the polishing robot evolution. In the field of industrial manufacturing, with industrial process standards improve, more and more manufacturing process only by traditional Industrial Robot position control is difficult to do. Complex curved surface of workpiece in poor consistency grinding applications, the position of the traditional control mode big rigidity, probably caused by the position error of workpiece robot system instantaneous overload, causing irreversible damage to the robot or parts. Most metal artifacts in through after molding, welding, casting and other basic processing procedure, still need to fine grinding polishing, deburring, as well as the polishing process can achieve the acceptance of qualified standard. Grinding process of a large number of diffuse dust, corrosive liquid chip and noisy noise easily lead to grinding operation personnel of all kinds of occupational disease harm security issues. At the same time also faced with low production efficiency and product of artificial poor accuracy and consistency of product molding problems, unable to realize batch production.
