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.

Korea Shows It Can
Machine tool builders in Korea have been playing a catch-up game for the past decade. A review of current developments in machine tool technology indicates that Korea is rapidly pulling up with manufacturers in Japan, Europe and the United States. The products from Korea closely match their counterparts from other global suppliers in terms of capability and quality.
