The FNL-220LSY-series multi-axis lathe from Chevalier Machinery has the ability to mill as well as turn. Y-axis travel for off-center milling (±2.2" from the centerline) is said to provide the largest range in the machine’s class. The lathe features high-torque live tooling and full C axes for the main and subspindles with minimum interpolation of 0.001 degrees. A hydraulic clamping cylinder with a disk break contributes to C-axis rigidity. These features facilitate throughput and reduce handling.
The lathe’s bar capacity is 2.0" for the main spindle. Its maximum cutting diameter is 12.6", with a turning length of 20.1". The swing over bed is 24.4". The chuck size is 8" for the main spindle and 6" for the subspindle. The X-, Y-, Z- and C-axis travels measure 8.7" × 22.0" × 4.3" × 360 degrees, respectively, with a traverse rate of 1,181 ipm.
A 60-degree, compound Y-axis slant bed design with linear roller guideways contributes to accuracy during high-speed machining. These guideways provide 30-percent stronger rigidity than regular ball ways, according to the company.
The lathe’s Sauter 12-station BMT 45 live turret provides tool speeds ranging to 4,000 rpm. An oversized clamping curved coupling improves cutting tool rigidity and accuracy.
The FANUC 0i-TF control features FANUC drives and motors plus a 10.4" color LCD with a fully conversational Manual Guide i program and 3D simulation. The lathe’s accessories include a chip conveyor, parts catcher, oil skimmer, tool presetter, turning holder package and rotary holders package.
