Multiple Grinding Operations in One Setup
The Okamoto UGM-NC is a CNC universal grinder built to complete multiple grinding processes without repeatedly repositioning the workpiece. An integrated grinding wheel turret supports plain cylindrical O.D., angle and end-face, and internal diameter grinding. Combining these operations in one setup helps maintain relationships between finished features while reducing changeovers and overall processing time. The platform gives manufacturers greater flexibility when grinding complex components that require both external and internal features.
Turret Configuration for ID, OD and Angle Grinding
The standard turret configuration provides I.D. and angle grinding capability, while an optional three-spindle turret expands the machine for I.D., O.D., and angle grinding. High-accuracy direct-drive spindle indexing provides controlled positioning as the machine transitions between operations. Temperature-controlled built-in spindle motors help limit thermal expansion and spindle thrust during extended grinding cycles. These capabilities make the UGM-NC a multi-process grinding machine for complex cylindrical components requiring several finished surfaces.
Automated Process Control and Grinding Accuracy
Okamoto’s conversational software simplifies grinding data entry for complex applications. The machine supports automatic grinding, multi-process cycles, shift-plunge grinding, and automatic dressing. Optional in-process measurement with automatic compensation can further control dimensional accuracy throughout the grinding cycle. A single-piece T-frame casting provides a rigid foundation, while V-V table ways reduce grinding pressure compared with conventional V-flat systems to support straightness and surface finish.
