High Cutting Accuracy is Realized Stably

  • Through enhanced accuracy and rigidity of mechanical structures including main spindle and feed axes and implementation of minimum command unit of Φ0.1 µm, high-accuracy machining is realized.
  • Positioning accuracy is improved by employing the high-rigidity linear roller guides on the wheel spindle stock feed and the table feed axes (RD23 and RD32).
  • Measures against thermal deformation ensure stable machining quality.

A Highly Efficient Machining Mechanism

  • Challenged higher grinding efficiency through high-speed feed via liner roller guides and use of high-rigid ball bearings, single-stroke grinding pattern using wide grinding wheel, and high output motors.
  • For the purpose of reducing non-cutting time, programming software with simplified structural design, simplified screen contents, facilitated setup changeover process, and general-purpose locator are equipped as standard.

Simple Programming Software Dramatically Reduces Operator Work

  • Equipped as standard with automatic programming feature so that grinding operation can start within 5 minutes from the start of conversational programming. The color programming screen shows various grinding and dressing patterns graphically, facilitating definition of workpiece shape.
  • Programming items are coordinated for each grinding cycle. Grinding conditions can be changed instantly and insertion of nose R compensation and manual process is also possible.

Multiple Functions and Safety Controls

  • Equipped with color LCD as standard for enhanced visibility.
  • Enhanced display features including path check display, grinding wheel trajectory display, machining spot display.
  • Safety is ensured by the triple checking functions (machining program, grinding path, and wheel motor overload detection).
