ACC 818SAiQ Form Grinder

The Okamoto ACC 818 SAiQ Form Grinder combines conversational CNC control with the rigidity required for accurate surface and profile grinding. Heavily ribbed Meehanite cast construction helps control vibration, while the ballscrew-driven table and full-contact double-V ways provide smooth movement and repeatable tracking. The machine supports surface, slot, step, form, and contour grinding, making it a flexible choice for machine shops handling varied part geometries and recurring production work. Automatic grinding and dressing cycles further support process consistency while reducing manual setup and adjustment.

 

Okamoto ACC 818 SAiQ Form Grinder Features:

  • Heavily ribbed Meehanite cast construction for rigidity, vibration damping, and long-term geometric stability.
  • Precision ballscrew-driven table with full-contact double-V ways for smooth movement and accurate tracking.
  • User-friendly “Touch & Teach” conversational programming for simplified setup and cycle development.
  • Surface, slot, step, form, and contour grinding capabilities.
  • Up to five programmable table-stroke positions for multiple workpieces and varied grinding operations.
  • Three-point diamond dresser with a two-point angle dresser for form dressing and a single-point dresser for straight dressing.
  • Automatic grinding, shift-plunge grinding, wheel-dressing, and chuck-datum cycles.
  • Touch-panel CNC interface for controlling and repeating programmed grinding operations.

Description
CNC Surface and Form Grinding for Production Work

The Okamoto ACC 818 SAiQ Form Grinder is a CNC-controlled machine for surface, slot, step, form, and contour grinding. Its heavily ribbed Meehanite cast construction helps damp vibration and maintain geometric stability during demanding grinding cycles. In addition, the ballscrew-driven table travels on full-contact double-V ways, providing smooth movement and repeatable tracking throughout the table stroke.

 

For machine shops comparing production surface grinding machines, the ACC 818 SAiQ combines rigid construction with programmable grinding and dressing functions. This configuration supports accurate stock removal, consistent profiles, and repeatable surface finishes across both recurring production jobs and complex form-grinding applications.

 

Conversational Programming and Automatic Grinding Cycles

Okamoto’s “Touch & Teach” conversational programming simplifies the creation of CNC grinding cycles. Operators enter job information through the touch-panel interface instead of developing each program with conventional CNC code. As a result, the control reduces setup complexity while maintaining consistent execution from one grinding cycle to the next.

 

Standard functions include an automatic grinding cycle, a shift-plunge grinding cycle, an automatic overhead dressing cycle, and a chuck datum cycle. The control can also manage up to five table-stroke positions. As a result, it can grind multiple workpieces that require different stroke lengths and positions within the same program.

 

Wheel Dressing and Process Control

The ACC 818 SAiQ includes a three-point diamond dressing system for maintaining straight and formed grinding-wheel profiles. Its two-point angle dresser supports form dressing, while the single-point dresser handles straight dressing. It also features automatic dressing, which helps maintain wheel geometry as the abrasive wears. This supports consistent profile accuracy and surface-finish quality throughout the production run.

 

This grinding equipment for machine shops provides the flexibility to move between flat surfaces, slots, steps, forms, and contours without transferring work to separate grinding platforms. In addition, its CNC control, programmable table strokes, automatic cycles, and integrated dressing system create a repeatable process for shops producing precision components with varied grinding requirements.
