STS – Slow Tool Servo’s capability consists of a positioning C-axis programmed for the workholding spindle which enables the diamond turning of complex surface structures such as torics, off-axes aspheres and progressive lens designs. This technology enables the machining of large sagitta workpieces without incorporating additional equipment and fixturing to the standard two-axes, Nanoform® machining system.
