Chevalier’s FBL-360L slant-bed lathe is said to provide a flexible, accurate solution for mixed-volume, short-run or dedicated high-volume applications. Capable of machining bars ranging to 4.5" in diameter, the lathe features a 45-degree slant bed, a rigid boxway structure and a programmable tailstock. The lathe offers a 15" chuck, 30.3" maximum swing, 22.4" maximum turning diameter and 80" maximum turning length.

A ribbed Meehanite cast iron mono-block casting features hardened and ground hand-scraped slideways to resist deflection and vibration. The lathe offers speeds ranging to 2,500 rpm, X- and Z-axis travels ranging from 12.6" to 78", and rapid traverse rates ranging to 708 ipm. Positioning accuracy is ±0.0002" in the X and Z axes, while repeatability is ±0.0001". It is powered by a 35-hp, AC digital spindle motor with a two-speed gearbox and 12" hydraulic chuck producing 735 foot-pounds of torque at lower rpm. The 10-station servo-indexing turret provides 0.5 sec. tool indexing time. The OD shank is 11/4", and the boring bar holds up to 2.5". A large curved coupling holds the carousel, which is clamped by hydraulic pressure. The lathe is equipped with a 12" three-jaw hydraulic chuck, oil skimmer, chip conveyor and Renishaw tool setter.

Methods Seeks the Perfect Machining Environment

With its new Precision Center, Methods Machine Tools is locking down environmental variables that could impact machining processes. Why? So North American manufacturers will no longer need to send parts, tooling and material to Japan or somewhere else to have intricate, sensitive or challenging test cuts performed.
