Chevalier Machinery’s FBL-460 vertical turning center features a 45-degree slant bed, rigid boxways and programmable tailstock. The machine offers a flexible solution for mixed-volume, short-run or dedicated high-volume applications at speeds ranging to 1,400 rpm.
The slant-bed lathe features a 6.3" spindle through-hole bar capacity. A 35-hp, AC digital spindle motor with a two-speed gearbox produces 735 foot-pounds of torque at low rpms. The 10-position servo-indexing turret offers a 0.5 sec. tool-indexing time. The OD shank measures 1.25" and the boring bar holds up to 2.5". The carousel is held by a large curved coupling and is clamped with hydraulic pressure. The machine is equipped with a 150-psi high-pressure pump, oil skimmer and chip conveyor.
The ribbed Meehanite cast iron mono-block casting with hardened and ground hand-scraped slideways is said to resist deflection and vibration for stable end-to-end cutting of long shafts. The machine offers a maximum swing of 33", turning diameter of 26.8" and turning length of 80". X- and Z-axis travels measure 14" × 83", respectively, with positioning accuracy of ±0.0002" and repeatability of ±0.0001".
Editor PickRobotic Cell Cuts Cycle Time, Improves Part Quality
Sew-Eurodrive Inc. worked with Okuma America’s authorized systems dealer, Gosiger Automation, to design an automated cell that includes an automatic, magazine bar feeder that loads 6-ft. lengths of barstock into the machine. The shop also switched to an Okuma twin spindle, twin turret turning center so all of the machining operations are completed in one setup, thus eliminating additional fixtures and operator intervention. The resultant system reduces cycle times and requires much less operator involvement. As a result, production time per part was more than cut in half – from about 5 minutes to 2 minutes, 20 seconds.
