Feature
These features make Campower's four-axis cam rotary tables highly valuable machining equipment, capable of tackling challenges in processing various complex workpieces while ensuring high efficiency, precision, and reliability. This is particularly crucial for industries that require high-quality machining, such as aviation, automotive, and mold manufacturing.
High precision
The RTD cam rotary table complies with the ISO-230-2:2014 international standard for segmental positioning accuracy and repetitive positioning accuracy, ensuring a high level of machining precision. This is crucial for customers with demanding high-precision machining applications.
High speed
The high rotational speed enables the cam rotary table to achieve positioning and rotation quickly, thereby improving production efficiency.
Fast transmission
Fast transmission capability contributes to rapid positioning and efficient processing, especially in production scenarios that demand short cycles.
Suitable for vertical and horizontal mounting
This design enhances versatility, allowing the cam rotary table to be configured for vertical or horizontal operation based on specific requirements, which is particularly useful for different machining needs.
Extremely low wear consumption
Utilizing cross-roller bearings helps reduce internal structural wear, thereby extending the lifespan of the equipment.
Various models and specifications
The RTD series comprises various models and specifications, suitable for workpieces of different sizes and weights, thus meeting diverse application requirements.
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. |
