What is Hollow Rotary Table?

Hollow Rotary Table, also known as hollow rotary actuator, programmable servo rotary table or hollow shaft indexer, is a precision rotary positioning device widely used in the field of industrial automation. The device adopts a hollow axis design, and its core structure includes a horizontally rotating circular platform (or turntable) with a hollow shaft hole in the center, which can realize the precise rotation of objects or workpieces around the specified axis. Its typical industrial application scenarios include robot flexible assembly workstations, semiconductor wafer processing equipment, optical inspection system rotary tooling, CNC multi-axis linkage machining centers, and laser cutting/welding rotary fixtures.

What is a Hollow Rotary Table used for?

 

Hollow-Rotary-Table

The hollow rotary table mostly serves to give a way for exact workpiece indexing and placement during machining or assembly operations. For jobs including drilling, milling, cutting, and grinding, it allows exact angle adjustments-qualities absolutely vital.

Thanks to its several stepper and servo motor configurations, which enable exact rotation and position of the workpiece, it is among the most often used reducers.

 

The Feature

 

  • Hollow Structure: By use of the hollow structure, it is feasible to transfer gases, liquids, electricity, signals, etc. through the table.
  • Versatility: Different application needs can be satisfied in fields like medical equipment, optical equipment, robots, etc.
  • High Precision and Stability: It can accomplish rotation control and micrometer level placement. Fields include optical measuring and precision machining call for it as well.
  • Programmability and Automation Control: It can operate in line with predefined programs and criteria.
  • Simple installation: Any motor can be coupled with several ratios from choice. Cross roller bearings fit for vertical, horizontal, and suspended installations.

FAQ

 

Q: What is the practical purpose of the "hollow structure" of a hollow rotary table?

A: The hollow structure is a core design feature of this product. It is primarily used to transmit gas, liquid, power cables, or signal lines through the center hole during rotation, preventing entanglement or interference between pipes. For example, in automated assembly, the hollow channel can provide air/power to the workpiece on the rotary table without affecting the platform's continuous rotation, significantly improving the device's integration.

Q: How to choose the appropriate reduction ratio?

A: The reduction ratio should be selected based on the load torque and speed requirements:
High reduction ratios (e.g., 50-500) are suitable for applications requiring high torque output (such as heavy workpiece turning and precision grinding), but at lower output speeds.
Low reduction ratios (e.g., 5-20) are suitable for applications requiring higher speeds and lighter loads (such as fast positioning for optical inspection).
Reference the "rated output torque" parameter for each model series to ensure that the torque of the selected model exceeds the actual load requirements (a 20%-30% margin is recommended).

Q: What is the difference between positioning accuracy and repeatability?

A: Positioning accuracy (unit: arc minute) refers to the deviation between the platform's actual rotation angle and the commanded angle (e.g., ≤1 arc minute, meaning the deviation does not exceed 1/60 of a degree), reflecting the accuracy of a single positioning attempt.
Repeatability (unit: arc second) refers to the consistency of deviation when positioning the same angle multiple times (e.g., ≤30 arc seconds), reflecting the long-term operational stability of the device.
Both are core parameters. For applications like precision machining and semiconductor testing, high-precision models (e.g., ≤1 arc minute for the HRT series) are preferred.

Q: What are the limitations of different mounting methods (vertical, horizontal, or suspended)?

A: The product supports various mounting methods, with specific limitations depending on the model's axial load and overturning moment parameters:
Horizontal mounting is suitable for most light-load applications.
For vertical or suspended mounting, ensure that the load weight and force direction do not exceed the model's rated axial load (e.g., the HRTZ-280 has an axial load of 13,000 N) and overturning moment (e.g., the HRM series has a maximum load of 6,300 N·m) to avoid compromising accuracy or lifespan.

Q: In which scenarios should models with high torque ratings be preferred?

A: High torque models (such as the HRM-260, which reaches 2950 N·m) are suitable for:
Loading heavy workpieces (such as sheet metal and large molds);
Situations with transient impact loads (such as the reaction force during drilling and stamping);
Multi-station simultaneous operations (where a rotary table needs to drive multiple workpieces simultaneously).

Q: How do I adapt the motor? Are additional accessories required?

A: All series are compatible with stepper or servo motors, depending on the motor power (e.g., the HRT series is compatible with 50-3000W, and the HRH series is compatible with 100-750W). Some models offer motor flange adapters for quick installation without additional customization.

Q: What precautions should I take during daily maintenance?

A: Regularly check the tightness of the connecting bolts (especially under high loads).
Avoid prolonged operation in environments with high dust and oil concentrations, and install a protective cover if necessary.
If the platform makes unusual noises or decreases in positioning accuracy, contact the manufacturer immediately for investigation. (Non-professionals are advised not to disassemble the internal gear structure.)
