KARATS L-28N CNC CNC LATHES

Technical Description

This CNC lathe features an extensive bed length of 413 inches with a width of 55 inches and a working depth of 24 inches, supporting large-scale machining operations. The center height is 55 inches with a maximum swing of 90 inches, allowing for heavy-duty workpieces up to 236 inches between spindles. It accommodates a maximum cantilever mass of 17,636 lbs and spindle diameters of 19 inches. The spindle operates at two speed ranges from 0.5 to 150 RPM, delivering a maximum rotational torque of 30 kN·m. The faceplate can grip diameters ranging from 19 to 86 inches. The machine’s tool rest provides rapid Z-axis movement at 196 IPM and cutting feed rates between 0.0004 and 0.4 inches per revolution over a 78-inch travel range. The X-axis traverse feed rest offers rapid movement of 78 IPM and a similar cutting feed range with a 60-inch travel. Power is supplied by dual spindle motors (50/80 HP each), dual Z and X-axis servo motors (10 HP each), and a 20 HP A-axis servo motor for rotational control. A dedicated 1/4 HP pump lubricates the spindle rest. The electrical system runs on 460V, 3-phase, 60 Hz. Controlled by dual FANUC18i-TA CNC units, this lathe supports precise multi-axis machining operations ideal for large, heavy, and complex parts requiring high torque, long-axis travel, and precise feed control. Its robust construction and powerful spindle motors ensure stable and accurate machining of oversized workpieces with sophisticated tool paths.
