Super Precision Profile Surface Grinding Machine

NP
series

NP520-F with splash guard

Capable of responding to 0.2 µm infeed command

We assure you the most important aspect of surface grinding machine, vertical axis' ±1µm following accuracy and repeat accuracy for 10 years. Because of integral structure of main spindle head and column, the machine provides stable feed accuracy and high rigidity for heavy grinding. High speed reciprocation for left / right table is originally equipped, and the machining time can be remarkably shortened.
