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.

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.
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.
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.

Okamoto ACC 818 SAiQ Specifications
The Okamoto ACC 818SAiQ is a CNC form grinder for precision surface, slot, step, form, and contour work where wheel geometry and repeatable table positioning directly influence the finished feature. A.W. Miller Technical Sales supports manufacturers throughout New York, Pennsylvania, Maryland, Delaware, Southern New Jersey, and Quebec with applications engineering, installation, training, and service support.
Its heavily ribbed Meehanite construction, ballscrew-driven table, double-V ways, Touch & Teach conversational programming, multi-position table stroke capability, and integrated 3-point diamond dressing system give the machine a distinct role between conventional surface grinding and specialized CNC form grinding.
Applications commonly evaluated for the ACC 818SAiQ Form Grinder include:
Conversational CNC setup supports complex grinding routines without requiring the operator to build every cycle from conventional G-code.
The 3-point dresser combines angle and straight dressing functions to establish and maintain wheel geometry.
Up to five table-stroke positions can support repeated features or multiple workpieces within one programmed setup.
Driven table motion improves repeatability for contour and form work where stroke location matters as much as surface finish.
Its CNC table control, form-dressing capability, and programming functions support slots, steps, contours, and dressed wheel forms in addition to conventional flat grinding.
The integrated 3-point diamond dresser provides a 2-point angle dresser and a 1-point straight dresser. The required dress sequence depends on the wheel form and finished geometry.
Yes. Its multi-position table-stroke capability can establish several stroke locations, which can be useful for repeated features or multiple workpieces when fixturing and clearance permit.
Wheel form, dresser access, feature depth, corner radii, workholding, coolant delivery, stock allowance, tolerance, and inspection method should be established before programming the cycle.
High-mix precision work, recurring mold and die details, and form-grinding jobs with several programmed positions can benefit because setup data can be established and reused more consistently.
