If you plan to integrate a rotary axis drive system into a high-performance machine or process, accurate motion is undoubtedly among your primary concerns. This is particularly true in machine tools, for example, where rotary axes help tools manipulate workpieces from various angles to create sophisticated parts. However, depending on the size requirements and loads involved, it can be difficult to build a precision rotary axis drive system from standard parts — particularly when it comes to zero backlash. That’s why it’s important to work with a motion control partner that leverages both proven expertise and a full range of modular axis products to make it a one-stop shop for all your requirements.
Typical Challenges When Building Rotary Drives
Here are some typical rotary axis drive elements that often challenge machine builders when specifying components for their systems:
- Accuracy and stiffness. Elaborate parts and assemblies demand accurate motion. For example, servo speed reducers must exhibit high stiffness to ensure precise control of control servo motor speed and torque while also minimizing or eliminating backlash.
- Diameter. Large-diameter rotary axes are especially susceptible to deflections which, even if minor, can affect the quality of the end product.
- Load management. In CNC machines, for example, the weights of workpieces and the tools that process them can vary from job to job. Rotary axes must account for all the potential load requirements including radial, axial and tilting.
- Integration delays. Time spent searching for products from multiple suppliers can be better spent getting the machine up and running or adapting it to new tasks.
- Maintenance. Lubricating various rotary axis parts is both cumbersome and a significant source of system downtime.
