Description
Vertical Rotary Surface Grinder for Production Applications

The Okamoto VRGDX Series is a vertical rotary surface grinder built for efficient stock removal and consistent surface finishes. Its segmented grinding wheel and rotary table configuration support productive grinding across a range of workpiece materials. The machine can process metals, carbide, ceramics, glass, and other brittle materials. Operators can also produce rotary or cross-hatch grinding patterns to meet different part and finish requirements.

 

Industrial Grinding Machine for Demanding Materials

Material requirements can vary significantly across production environments. The VRGDX Series provides an industrial grinding machine platform capable of handling both conventional metals and harder, brittle materials. A magnetic chuck secures workpieces during operation, while the machine’s rigid construction supports stable grinding under load. The rotary configuration also provides efficient material removal when processing components with broad, flat surfaces.

 

High Precision Surface Grinding with Simplified Control

The VRGDX Series combines Okamoto’s FX Controller with a three-point column support system for controlled, repeatable operation. The three-point design simplifies column adjustments while helping maintain machine accuracy. In addition, a fully enclosed cover contains coolant and grinding debris during operation. These features support high precision surface grinding while providing straightforward machine operation for recurring production requirements.
