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 RTC 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 rigidity
High rigidity ensures the stability of the mechanical equipment, reduces vibration and deformation, and helps achieve high-precision machining.
High torque
The high torque capacity enables the RTC series cam rotary tablesto handle applications high power torque, which is crucial for machining large or heavy workpieces.
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.
Big spindel bore
The Big spindel bore design makes it easier for customers to install and accommodate various sizes of workpieces.
Hydraulic embracing
The hydraulic embracing function helps secure the workpiece, ensuring its stability, especially for high-precision machining.
Drive mode
Unlike the commonly used worm and gear mechanisms in the market, COMPOWER 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. |
