Chevalier Machinery Inc. has added the new FRG-400/600S Series of rotary surface grinders to its grinder product lineup.
The FRG-S Series of rotary surface grinders have an easy setup, is designed for heavy loads and is fully enclosed for CNC rotary surface grinding. The series is said to seamlessly increase efficiency and productivity for such industries as aerospace, automotive, energy, medical and semiconductor in order to meet current and future market demands.
The spindle seat structure is supported by six Class 7 (P4) precision angular contact ball bearings that withstands heavy-duty grinding. And the flexible coupling connecting the spindle to the motor offers a precise balance correction process, which effectively reduces vibration and ensures grinding quality.
The rotary table transmission features hydrostatic bearing system. The elevating transmission is driven by a C2-grade ballscrew and timing belt with an AC servo motor, which provide high torque, speed and accurate positioning. The crossfeed transmission also uses a C2-grade ballscrew, combined with a direct drive AC servo motor that improves the grinding accuracy and achieves mirror-finish quality. Linear guideways on both axes improve the grinding accuracy with a minimum increment of 0.00004" (0.001 mm).
The machine’s interior grinding space and double-door design contribute to ease of access for workpiece loading and unloading. The drainage system easily removes swarf for cleaning, and the machine is fully enclosed with a sealed, waterproof metal guard.
The FRG-S Series is designed to be user friendly. Chevalier’s exclusive next generation Smart iControl incorporates production efficiency, which simplifies operation procedures and greatly enhances the performance of Chevalier CNC grinders.
