There is a growing need for ultra-precision machining in a wide range of fields (e.g. machine tools, semiconductor manufacturing equipment and electronic component manufacturing machines). We developed with pursue high-precision and generality our SSPG Series to meet these wide-ranging needs. It is possible to support all processes from rough machining to finish machining with one spindle through the realization of higher precision, power and rigidity. Moreover, customization is simple, so we are also able to change the specifications to those for grinding or milling. We will be realized customer's needs by SSPG series.
