Chevalier’s FBL-360 slant-bed lathe, with its 45-degree slant bed, rigid boxways structure and programmable tailstock, features a 15" chuck, 4.5" bar capacity, 30.3" maximum swing, maximum turning diameter of 22.4”, maximum turning length up to 80".
The ribbed Meehanite cast iron mono-block casting––with hardened and ground hand-scraped slideways––helps resist deflection and vibration during heavy machining and ensures stable end-to-end cutting of long shafts.
The FBL-360 offers a flexible, accurate and efficient solution for mixed-volume, short-run or dedicated high-volume applications, delivering fast parts machining of bars as much as 4.5" in diameter at speeds as high as 2,500 rpm, X and Z travels of 12.6" and up to 78" and 708-ipm rapid traverse. The X- and Z-axes positioning accuracy is ±0.0002", while repeatability is ±0.0001".
The lathe features 35-hp, AC digital spindle motor with a two-speed gearbox and 15" hydraulic chuck. It produces 735 foot-pounds of torque at lower rpm. The fast ten-position servo-indexing turret offers 0.5-sec. tool indexing time. The OD shank is 1 1/4" and the boring bar holds as much as 2.5". The carousel is held by a large curved coupling and clamped by hydraulic pressure.
Standard equipment includes 15" three-jaw hydraulic chuck, oil skimmer, chip conveyor and Renishaw tool presetter.
