CHEVALIER MACHINERY, INC. FBL-460 HORIZONTAL MACHINING CENTER

The Chevalier Machinery, Inc. FBL-460 is a robust horizontal machining center designed for heavy-duty turning applications. It features a single main spindle with a maximum turning diameter of 26.7 inches and a maximum turning length of 30 inches, accommodating bar diameters up to 5.5 inches. The spindle operates at speeds up to 1,500 RPM, powered by a high-torque AC digital motor capable of delivering up to 50 HP, supported by a two-speed gearbox for versatile cutting conditions. The machine’s structure employs a 45-degree slant-bed design with ribbed Meehanite cast iron construction and a torque tube frame to maximize rigidity, vibration damping, and thermal stability during heavy machining. Precision is ensured with hardened and ground, hand-scraped slideways and an X, Y, and Z-axis rapid traverse rate of 18 inches per minute each, providing accurate and fast positioning. The lathe integrates a servo-indexing turret with multiple tool stations for efficient tool changes and options for live tooling to enhance machining flexibility. Its control system supports high positioning accuracy of ±0.0002 inches with repeatability of ±0.0001 inches, suitable for mixed-volume and high-volume production runs. Standard features include a programmable tailstock, chip conveyor, and high-pressure coolant system. This machine is well-suited for machining large, complex workpieces in industries demanding rigid, high-precision turning capabilities.
