Description
Production Surface Grinding Machines for Controlled CNC Grinding

The Okamoto ACC-8•18 CNC Form Grinder supports production surface grinding applications in machine shops that require consistent form accuracy and repeatable surface finishes. The saddle-type configuration provides stable axis movement during grinding operations, which helps maintain positional accuracy across extended production cycles. In addition, the CNC control allows precise execution of programmed grinding paths. This supports form grinding and surface grinding within the same setup, reducing manual intervention and improving process repeatability.

 

CNC Form Grinding with Process Stability and Accuracy

The ACC-8•18 CNC Form Grinder handles both profile and surface grinding within a single CNC-controlled platform. The control coordinates wheel position, feed rates, and axis motion to maintain consistent stock removal and hold tight tolerances throughout the grind cycle. This level of control reduces manual adjustment and supports repeatable results across complex part geometries.

Machine rigidity plays a direct role in grinding performance. The stable saddle construction minimizes vibration during cutting passes, which helps maintain surface finish quality and limits part-to-part variation during extended production runs.

 

Grinding Equipment for Machine Shops Focused on Efficiency

This grinding equipment for machine shops balances flexibility with production efficiency. In addition, operators can transition between form grinding and surface grinding without changing machines or workflows to reduce setup time and support streamlined job sequencing.

CNC control, rigid construction, and saddle-type motion work together to maintain stable grinding conditions across a range of applications. This configuration supports consistent output, controlled tolerances, and repeatable surface finish quality in production grinding environments.
