IGM15NCⅢ-2B

CONCEPT

Equipped with textless dialogue software. An internal grinder that can drive 2 spindles independently.

Feature

・Composite grinding is possible with a 2-axis spindle.

・The optimum grinding and dressing conditions are automatically created by simply inputting the grinding wheel grain size, the comb diameter and the comb width through the automatic setting function of machining data, and the constant work diameter.

・File management supports registration of 21 types of wheel and work data. 

・There are no characters on the screen, and it is completed by touch input while looking at the panel input.

The touch panel eliminates unnecessary switch connections.

・Standardized fully closed cover, wheel and work spindle uses AC spindle servomotor.

・Eco-friendly fully closed cover realizes stable feed rigidity and high machining accuracy.
