Summary

The Okamoto IGM-15NCIII is a CNC internal grinding machine designed for precision machining of internal diameters, faces, and tapers in metal components. Its core function is the high-accuracy removal of material from the interior of cylindrical parts, enabled by programmable multi-axis control and versatile grinding capability (I.D., O.D., faces) in a single setup. Notable differentiators include fine feed resolution (0.00001"), touch-screen conversational CNC, and in-process dressing.

Key Capabilities

• CNC control with touch-screen functionality and conversational programming via Fanuc OiTD
• Grinding operations for internal diameters, outer diameters, faces, straight, taper, and multi-step profiles
• Single-chucking machining of I.D., O.D., and faces
• Minimum feed increments of 0.00001"
• Programmable wheelhead with three selectable speeds
• Workhead with variable spindle speed from 100 to 850 rpm
• In-process dressing via interrupt function in automatic cycle
• Rigid construction for prolonged precision
