The Ultimate in Machining, Requiring Machine Accuracy in All Axes: fcross axis, longitudinal axis, vertical axis.
Free-form surface grinding (free-form machining) is a process that uses a grinding wheel to cut and finish the surface of a workpiece with a curved surface that cannot be expressed by a simple mathematical formula.
If machining accuracy is defined as "the result of the transcription of the relative motion of the tool and workpiece, " then this machining process is the "ultimate in ultra-precision machining, " requiring machine accuracy in each of cross axis, longitudinal axis, vertical axis, and rotary axes, accuracy in synchronization of each axis (synchronization accuracy), and repeatable positioning repeatability.
