The Okamoto ACC-DX Series is an automatic-control column surface grinder built around straightforward large-part grinding rather than full CNC contour programming. 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.
A fully supported table, high-rigidity traveling column, Vee-and-flat table ways, servo-driven vertical feed, and fine infeed control make the DX Series relevant to manufacturers that need repeatable coarse grinding, fine grinding, spark-out, and table-stop functions on larger components.
Applications commonly evaluated for the ACC-DX Series include:
The control organizes core surface-grinding functions without adding unnecessary CNC complexity to straightforward flat work.
Small vertical increments support controlled finishing passes and careful approach to final size.
Vee-and-flat ways distribute load while maintaining linear tracking across the grinding stroke.
Controlled wheelhead movement improves repeatability between roughing, finishing, and spark-out portions of the cycle.
It is positioned as an automatic-control column grinder rather than the more advanced CNC DXNC platform. It is intended for repeatable surface-grinding cycles where full 2-axis CNC interpolation is not required.
DX can make sense for large flat work with recurring automatic cycles, while DXNC becomes more relevant when programmable dressing, coordinated axis motion, or more complex grinding patterns are required.
Part support, magnetic holding force, table load, stock distribution, wheel contact, coolant coverage, thermal growth, and flatness inspection should all be included in the process plan.
Spark-out allows the wheel to traverse without additional commanded infeed, helping stabilize size and surface finish after the primary stock-removal passes.
Yes. The decision should be based on part geometry, repeatability, dressing requirements, operator involvement, production mix, and whether coordinated axis motion adds measurable process value.
