CHEVALIER MACHINERY, INC. FNL-220LSY HORIZONTAL MACHINING CENTER

Technical Description

The Chevalier Machinery FNL-220LSY is a sophisticated horizontal machining center engineered for complex multi-spindle turning and milling operations. This machine features dual main spindles, each rated at 4,500 RPM with 20 HP output, enabling simultaneous or sequential machining on multiple workpieces or different features of a single part. The main spindles accommodate up to 10.6" turning diameter with maximum 20.1" turning length and feature 8" chuck capacity with 2.5" maximum bar diameter. A dedicated 6,000 RPM sub-spindle with 10 HP provides additional machining versatility, while a rotary tool spindle operating at 6,000 RPM with 7.4 HP enables milling and boring operations. The machine utilizes BMT45 tool shanks with capacity for 16 turning tools and 16 rotary tools, allowing one simultaneous cutting tool operation. The four-axis configuration includes robust travel capabilities: 8.7" X-axis, 4.3" Y-axis, and 22" Z-axis travel, all delivering rapid traverse and feed rates of 1,181 ipm. This configuration makes the FNL-220LSY ideal for high-precision production of complex components requiring integrated turning and milling capabilities, particularly suited for aerospace, automotive, and medical device manufacturing where multi-axis simultaneous machining enhances throughput and accuracy while reducing secondary operations.
