Introducing the FDG-700

Chevalier’s new double-sided grinder machines small and medium size flat workpieces in no time flat.

SANTA FE SPRINGS, Calif., June 1, 2018 – Equipped with the latest technology in graphic controls, engineering and ergonomics, Chevalier’s new FDG-700 is loaded with the features that make the innovative double-sided grinder the ideal machine for a variety of workpieces.

The FDG-700 features our proprietary PC-based graphic control with a 10.4” touch screen monitor, making it possible to intuitively operate the machine entirely by conversational graphic control.

The new machine also features a high-precision digitally controlled pneumatic system that automatically adjusts according to the selected pressure. The high-precision contact measuring system includes grinding height control and dressing monitoring.

The FDG-700 is perfect for mass production of small and medium size work pieces that demand high-precision and high efficiency within a small footprint. The new machine has been ergonomically designed for greater efficiency and productivity.

Variable speed spindle coupled with a high-torque gearbox provide the flexibility needed to machine all types of work pieces. Optimum surface finishes, flatness and parallelism with a narrowest of tolerances provide superior results for a wide range of applications, including precision grinding for crystals, ceramics, optical glass, semiconductors, tungsten carbide, metal and other hard and brittle materials.
