There is here disclosed a nozzle type ELID grinding apparatus comprising a conductive grindstonehaving a contact surface with a workpieceand an ion supply nozzlethat supplies an electrolytic mediumcontaining hydroxyl ions (OH) onto a surface of the conductive grindstone, the workpiece being ground while the surface of the grindstone is dressed by electrolysis or chemical reaction. Furthermore, the apparatus comprises a grindstone power sourcefor setting the conductive grindstone to be a positive potential (+).

Method and apparatus for nozzle type ELID grinding

There is disclosed a micro surface shape measurement probe including a probe shafthaving at a distant end thereof a probe memberfor contacting an objectto be measured, a probe bodyprovided with support means for movably supporting the probe shaftin a non-contact manner, a pressing device for pressing and moving the probe shafttoward the objectto be measured, a piezoelectric sensorincorporated in the probe bodyso that a reactive force acts to a pressing force applied to the probe shaft by the pressing device, a load detecting deviceto measure a load acting on the piezoelectric sensor, a control devicefor adjusting the pressing force applied by the pressing device based on the load detected by the load detecting device, and a displacement amount measuring device for measuring a position of the probe memberin contact with the objectto be measured by the pressing force adjusted by the control device
