Highly accurate and highly efficient machining of large, complex-shaped parts

POINT 01
Complete all machining processes of large, complex-shaped parts with an NC-BC universal head
  • The NC-BC universal head can machine multiple surfaces, including inclined and curved surfaces, with one chucking. This reduces the setup time.
  • Spindle speed can be selected from 6,000 to 20,000 min-1

POINT 02
Automatic optimization of servo control by SERVONAVI improves productivity while maintaining high machining accuracy
  • Servo parameters are automatically set optimally according to the weight of parts and jigs, shortening the machining time while maintaining machining accuracy
  • The machine automatically optimizes servo parameters in accordance with changes over time, such as changes in sliding resistance, to maintain high machining accuracy

POINT 03
High accuracy is maintained over the long term
  • The Thermo-Friendly Concept, Okuma's unique approach of "accepting temperature changes," ensures stable accuracy without the need for special cooling equipment or excessive air conditioning management
  • The accuracy stability diagnosis function diagnoses changes in machine accuracy to visualize the impact of room temperature changes on machine accuracy and ensure the reliability of measurement and machining
  • 3D calibration, which calibrates the spatial accuracy of the machine, is used for regular inspections and calibration of machine accuracy, maintaining high accuracy over the long term
