Patent 4,683,679 relates to a concept for a grinding machine which uses hydrostatic bearings which support the grinding wheel (and roll dressing system when used,) from both sides and not a cantilever as in most grinders today. This provides a phenomenaly high level of static and dynamic stiffness. The unique design allows the wheel and or dresser to be changed very quickly, without any dismantaling of the machine's structural elements, therefore maintaining a high level of mechanical stability. Using a solid base, the wheel is kept stationary and the workpiece is moved to and from the grinding wheel, minimizing slideways and unnecessary axes of motion that detract from the overall vibrational stability and stiffness found in most of today's grinding machine designs. This incredibly high stiffness and vibrational stablity makes this sytem ideally suited to grinding brittle ceramics and for nano-machining. Ironically, the mechanical principles used in this concept are much like those used by the original knife grinders of old.

The Sculptor 1TM Concept (right) shows a single-axis, electro-plated superabrasive wheel machine. The workpiece is set in the fixture at grinding depth with only fine adjustment being made, for wheel wear, in the fixture via a piezo-electric or hydrostatic wedge. The turret brings the fixture into grinding position and the single axis, hence the name Sculptor 1TM , drives the part/s through the grinding wheel. The slideway is vertical and therefore the work area remains clean and free from grinding debris. Air cut time is minimal. Optimization occurs when the load and unload time is balanced with the grind cycle.
