Application and characteristics of hollow rotary platform reducer/Heavy Duty Hollow Rotary Tables/Indexing Rotary Table: 
Indexing Rotary Table can directly replace  cam divider and DD motor. Indexing Rotary Table is a digital rotary platform with high positioning accuracy, with low-cost potential, and occupies a strong market in the rotary platform category.

1. Direct connection: simple design improves reliability.
2. Large diameter hollow rotating platform: simple wiring and piping
3. High positioning accuracy
4. Short time positioning: the positioning of inertial load can be realized in a short time
5. Simple origin return: save the trouble of design and parts procurement

B.Indexing Rotary Table is a series of planetary servo reducers. It uses high rigid cross bevel roller bearings to present an integrated design with the rotating platform surface, which can bear the disc device with large inertia. The whole group is equipped with stepping motors and drivers.

C. Indexing Rotary Table can replace the DD motor and divider to achieve balance between them. Repetitive positioning accuracy ≤ 5 seconds, the motor is easily prepared and the load is stable. It can be combined with AC servo Mayi angle segmentation, which can not only meet the digital control that the divider cannot achieve, but also comparable to DD motor. It can greatly reduce the cost and bring you unexpected results!

D. Six applications of hollow rotary platform reducer/Indexing Rotary Table
1. Load inertia change
2. High precision positioning
3. Apply inertia load
4. High precision positioning using hollow holes
5. Optical with hollow holes
6. The special products of hollow rotary platform reducer using hollow hole suction are widely used in aerospace, military equipment, semiconductor equipment, medical equipment, robots, manipulators, communication equipment, pharmaceutical equipment, printing equipment, packaging machinery.

How much do you about Indexing Rotary Table?
1. Bearing supporting the rotating platform: the type of bearing used by the rotating platform.
2. Allowable torque: acceleration torque and load variation should also be used below the allowable torque.
3. Inertia: the sum of the inertia of the rotor of the motor part and the inertia of the reduction mechanism part converted on the rotating platform.
4. Resolution: that is, the number of pulses required to rotate the platform for one revolution.
5. Repeated positioning accuracy: it shows the number of errors in repeated positioning from the same direction at the same position.
6. Forward and reverse angle error: refers to the difference between the stop angle when the rotating platform is positioned from the forward direction and the reverse direction at a certain position.
7. Angle transmission error: refers to the difference between the logical operation angle of the rotating platform calculated from the input pulse number and the actual operation.
8. Allowable thrust load: indicates the allowable value of axial load applied from the axis direction of the rotating platform.
9. Allowable inertia load: when the load is applied to the eccentric position of the center of the rotating platform, there will be a force to tilt the rotating platform. The amount from center to eccentricity at this time × The allowable value calculated by the load.
10. The parallelism of the rotating platform indicates the inclination of the mounting surface of the rotating platform relative to the equipment side mounting surface of the actuator.

What are the benefits of using a rotary table?

Rotary tables offer a range of benefits in industrial manufacturing applications. They are designed to provide superior accuracy, speed, and precision while also offering increased flexibility and versatility. The rotary table also allows for faster setup times and more efficient utilization of existing machine tools, as it can be used to complete multiple operations on a single workpiece. Additionally, rotary tables can help to reduce down-time and increase the overall productivity of a manufacturing process. These tables provide the ability to quickly and accurately reposition, rotate, and index workpieces, reducing the need for additional setup and adjusting. This can help to reduce labor costs, improve production accuracy, and increase throughput.

What types of operations can be performed on a rotary table?

Rotary tables are typically used for machining operations like drilling, tapping, and facing, but can also be used for milling and honing. These tables can be used to create curved or straight edges, or can be used as a truing or calibration system. Rotary tables are also used in engraving applications, where they can be used to produce intricate details in metal or plastic parts. Applications range from simple lettering and artwork to complex numerical control systems and detailed imagery. These tables can also be used to create grooves, spiral patterns, and other complex shapes.

What factors should be considered when selecting a rotary table?

When selecting a rotary table, it’s important to consider the size, weight, and power requirements of the application. Tallman Robotics’ heavy duty rotary tables are designed to withstand high torque loads, which makes them ideal for industrial applications. Additionally, the speed of the table is important to consider – if you are processing high volumes of material or parts, a faster table may be required. Finally, consider the table’s accuracy and repeatability. Tallman Robotics’ tables are highly accurate and repeatable, ensuring the highest precision for your application.

How to correctly install and operate a rotary table?

Before installing and operating a heavy duty hollow rotary table, it’s important to ensure that all safety measures are followed. All guards and protective shields must be in place, and all warning labels should be read and understood before attempting to use the table. Once the table is installed, it is important to thoroughly test and calibrate it before use. Be sure to check for levelness and make any necessary adjustments to ensure optimal performance. Additionally, regularly check the table for excessive wear and tear, and replace any worn or damaged parts as necessary.


Tallman Robotics’ heavy duty hollow rotary tables provide accurate and reliable performance for a wide range of industrial applications. They are available in a variety of sizes and can be custom-engineered to meet the demands of your application. When selecting a rotary table, it’s important to consider the size, weight, power requirements, and accuracy of the table in addition to the types of operations that will be performed on it. It’s also important to ensure that all proper safety procedures and precautions are followed when installing and operating a rotary table. By selecting the right rotary table and using it correctly, you can ensure that your application runs efficiently and reliably, requiring minimal maintenance and downtime.
