Vertical CNC Internal Grinding Machine

Vertical CNC Internal Form Grinders
Easy setup, specialized and with graphic conversational control

The FVG-10i, a vertical CNC internal form grinder that features Chevalier's grinding technology, was developed to meet the market demand for difficult grinding processing. In the hydraulic motor industry, our technology meets the standards required for machining stators for cycloid motors and steering gears, which are common hydraulic power units widely used in the petrochemical, construction, shipping, engineering, mining and metallurgy, along with other industries.

The SMART iControl's powerful computing force enhances HMI (Human Machine Interface) graphic conversational control for greater precision with the FVG-10i, which is capable of providing grinding solutions with the optional accessories and fixtures needed for industry-specific requirements.
