    Drive mode

    Unlike the commonly used worm and gear mechanisms in the market, COMP Precision Machinery employs roller cam mechanisms for both the fourth and fifth axes to drive the machine.

    Roller cam mechanisms and worm and gear mechanisms are two different mechanical structures, and they differ in terms of stability, rigidity, and wear and tear:


    Roller Cam Mechanism Worm and Gear Mechanism
    Stability Exhibits higher stability. The design of roller cams allows for smoother motion, reducing vibration and instability.
    Lower stability, with potential for vibration and uncertainty, especially under high loads or high-speed conditions.
    Rigidity Possesses higher rigidity, providing better resistance to external forces and torque. Relatively softer, potentially experiencing some deformation when subjected to external forces.
    Wear and Tear Lower wear and tear, capable of maintaining high precision over extended periods. May experience wear and tear due to friction on contact surfaces, particularly during prolonged high-frequency use.
    Backlash Typically achieves zero backlash, offering more accurate motion control. May have some backlash, affecting precision and the accuracy of motion.
