CX
Heavy Duty

Overview

Kingston's CX series heavy-duty precision lathes are built for cutting heavy and long workpieces in the energy, mining, textile, paper, and transportation industries. Utilizing the same headstocks and spindle bores as Kingston’s tried-and-true engine lathes, the CX is available in a wide variety of configurations so you can customize your machine to your exact needs. Choose from a 4.09”, 7.09”, 10.1”, 12.5”, or 14.7" bore, 34" or 40" swing (30" swing available with CX 12 model only), and lengths from 80" – 240". It is equipped with a V8 hydraulic turret and 5.45 HP and 9.5 HP AC servo motors that drive the X- and Z-Axis respectively. The headstock has 4 gearshifts controlled by hydraulics for greater torque and the main spindle has a three-point bearing support system – making it ideal for cutting heavy and extremely hard materials.
