The helical rack and pinion system is one of the most precise and stable motion-transmission mechanisms used in CNC machines, especially fiber laser cutting systems. The
angled (helical) tooth design increases the contact surface between the rack and pinion, resulting in significantly smoother, quieter, and lower-vibration motion compared to
standard straight-tooth systems.
The helical structure enhances load-carrying capacity, improves torque transmission, and reduces backlash, ultimately delivering higher accuracy, greater stability at high
speeds, and superior cutting quality. Manufactured from hardened materials with precision machining, these systems offer long service life and reliable performance even
under heavy-duty operation.
Integrating a helical rack and pinion system into fiber laser machines greatly boosts the performance of the X and Y axes, enabling higher travel speeds, faster response, and
excellent repeatability throughout the cutting process.
