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.
