1 CNC LATHE TURNING CENTER PL-20A

2 CNC LATHE TURNING CENTER For High Precision, High Speed and High Productivity MAIN FEATURE Introducing the latest and strongest CNC Lathe PL20A that has satisfied the requirements of production sites through integration of advanced functions to a compact body!. High-rigidity bed to support powerful, heavy-duty cutting Rapid turret featuring 0.5 seconds for 1 station Rapid feed of 20m/min(787.4 ipm) for X and Z axes 45 slant bed structure The strongest spindle power in its class:19.5 kgf.m Anti-backlash and anti-vibration mechanism Maximum machining diameter: Ø240

3 The CNC lathe PL20A featuring high quality, high reliability and high productivity is indispensable in the era of FA. The anti-backlash and anti-vibration mechanism assures highaccuracy machining. The AC servo motor used on the X and Z axes of the feed drive system is connected directly to the screw, and there is near-zero backlash and vibration. Power-up series (P series)(1:8) AC spindle motor is installed on the spindle drive system. As the machine does not use gears, vibration is near zero and high machining accuracy is assured at all times The rapid indexing turret featuring 0.5 seconds for 1 station has significantly reduced the idle time. The nonstop random index system which uses index motor developed by Samsung in the turret indexing enables tool selection within 0.5 seconds for 1 station. The rapid teed rate allows positioning at a speed as fast as 20m/min(787.4 ipm) for X and Z axes. The model PL20A has considerably reduced the idle time, ensuring high-efficiency operation. Central Integrated Operational Panel Central Integrated Operational Panel allows operator avoid unnecessary movement, and designed for the best performance, also, 90 rotate panel gives operator much convenient.

4 PL-20A High Quality, High Confidence, High Productivity TOOLING System The high-rigidity slant-type bed featuring superior stability even during powerful, heavyduty cutting The bed structured in the form of pipe featuring high resistance to rotation and bend suppresses cutting reaction even during powerful, heavy-duty cutting, ensuring high accuracy machining. The slant-type bed ensures superior access to the work piece and efficient discharge of chips. Cross-Section of the Bed Slant-design bed makes the work go smoother, chip removal much easier. Tough tubular construction stands up to the hardest cutting jobs. Careful consideration has been given to every corner of the machine. The separate coolant tank also makes cleaning easier. As the coolant tank is separated from the machine, there is no thermal effects created from chips and coolant, and cleaning is quite simple. High-accuracy is assured even during long, continuous operation by taking appropriate measures against thermal displacement of the spindle. As the spindle speed tends to become faster, it is important to take appropriate measures to prevent spindle heating and thermal displacement. The spindle does not use any gear, one of the sources of heat, and is designed in a structure featuring high heat removal effects. Thermal displacement is positively prevented through installation of a fan at the rear of the machine. The ball screw, the feed mechanism, is structured in 3-point support to which pre-load is applied to prevent thermal expansion. Spindle Power and torque diagram
