The FSG-618SP and FSG-818SP models represent Chevalier’s Manual Surface Grinders (SP Series), engineered for users who demand high-precision grinding and exceptional surface finish quality. These machines are constructed from Meehanite cast iron with a reinforced ribbed column and hardened and ground guide ways, providing maximum machine stability and vibration damping for superior performance.

Precision movement is guaranteed by a carriage system where the saddle travels on Turcite-B-coated and hand-scraped double V guideways, while the table traverses on linear ball bearings and D2 hardened and ground guideways. Both the elevating and cross-feed leadscrews are hardened and ground for lasting accuracy. The spindle system is a core strength, featuring a powerful 2 HP motor and a dynamically balanced, permanently lubricated, and sealed cartridge-type spindle. This spindle runs on two pairs of Class 7 (P4) angular contact ball bearings, ensuring high rigidity and thermal stability at speeds up to 3,450 rpm (60 Hz). Operator comfort is addressed with a vertical handwheel positioned at waist level for ergonomic control. Furthermore, every machine includes an automatic lubrication system to ensure continuous component health and extended operational life. These models are capable of producing a mirror surface finish accurately and efficiently, making them ideal for toolroom, mold, and die applications.
