The most important feature of the ring polishing machine is high processing accuracy and outstanding efficiency, which can stably achieve the accuracy requirements of the large aperture component (Φ400-2000mm) surface shape 1/20λ. The products of the ring throwing machine have been put into major national projects in the fields of national defense and aerospace.
The application in optical polishing greatly improves the manufacturing accuracy and efficiency of optical components. Here are some of the main applications of CNC technology in optical polishing:High precision control: CNC technology can achieve high precision control of the position of the polishing tool and the workpiece, ensuring that every step of the polishing process can achieve the expected accuracy. This is essential for the surface quality and shape accuracy of optical components.
The main advantage of IBF is the non-contact machining method, which avoids the potential damage caused by mechanical tool contact in traditional methods. IBF is particularly suitable for aspherical machining, providing extremely high stability and accuracy and preventing sub-surface damage.
Ion beam polishing of optical components based on CCOS principle The use of ion beam instead of the traditional polishing head, through the ion sputtering effect between the ion beam and the optical component to remove the surface material of the optical component, based on stable ion source technology and precise numerical control technology, ion beam polishing also has the characteristics of high precision and high convergence.
magnetorheological polishing fluid in a magnetic field. The magnetorheological fluid is mainly composed of discrete micron magnetic particles, carrier fluid and surfactant. It has the characteristics of magnetic properties, rheology and stability.
When there is no applied magnetic field, the magnetic particles are distributed irregularly, and the magnetorheological fluid is a flowable liquid. Under the action of the applied magnetic field, the magnetic particles are distributed in chain shape, and their rheological properties change sharply (millisecond order), showing solid like properties. After the magnetic field is removed, it will immediately return to the original liquid body properties.
Computer Controlled Optical Surface (CCOS) polishing technology was adopted. According to the established mathematical model, the material removal amount is controlled by controlling the motion path, relative pressure and resident time of the grinding head on the machined surface. It has higher polishing efficiency than the traditional polishing process, and has higher surface shape accuracy index.
