The KCR Series CNC 4th Axis Rotary Tables are high-performance rotary worktables designed to expand the capabilities of CNC machining centers. By adding a 4th axis, the KCR series enables multi-face machining, angular positioning, and complex surface milling, greatly improving productivity and accuracy.
Engineered with a high-precision worm gear mechanism, robust cast-iron body, and servo motor drive, the KCR rotary tables deliver outstanding rigidity, repeatability, and reliability for industrial applications.
