24" x 40" Chevalier FSG-2640TX Surface Grinder | Column Type | 15 HP | Over-Wheel Dresser

1995 Chevalier FSG-2640TX

3-Axis Automatic Column-Type Surface Grinder

"High-Capacity Precision for Large Scale Die & Mold Work"

This 1995 Chevalier FSG-2640TX is a heavy-duty, column-type workhorse designed for large-scale precision grinding. S/N J485C001 is a well-equipped unit that excels in handling massive die blocks and large surface plates where smaller, saddle-type grinders fail to maintain accuracy.

With a massive 24" x 40" capacity and a robust 15 HP spindle, this machine provides the rigidity and power required for aggressive material removal while maintaining the fine finishes Chevalier is known for.

Dealer Note: "At 18,000 lbs, the FSG-2640TX is built for stability. S/N J485C001 is a rare 'TX' series unit that combines a massive 24-inch width capacity with the convenience of an over-the-wheel dresser. It is an ideal 'bridge' machine for shops that need VMC-level table capacity in a dedicated precision grinder. This machine is currently under power and ready for inspection."
