What is a hollow rotating platform & Hollow Indexing Table?
Hollow Indexing Table is a new rotating load device.

Hollow Indexing Table integrates the advantages of high transmission efficiency, high precision, high rigidity and high cost performance. Hollow Indexing Table integrates the advantages of servo motor and convex, and fully achieves a balance between these products.

Compared with other similar transmission and positioning products, Hollow Indexing Table can not only meet the direct load of one-to-one load that the servo motor can not do, but also make up for the fact that the divider can not realize the positioning of any angle at any angle. In terms of accuracy, Hollow Indexing Table can also be comparable to DD motor, but the cost is much lower than DD motor. Used with servo motor, it can fully meet your requirements for circumferential positioning control.

Characteristics of Hollow Indexing Table:
1. Hollow structure: the rotary table of the hollow rotating platform is a hollow structure, and the servo motor is connected to the side, which is convenient for the installation of air pipe and wire in the fixture.

2. Any configuration of motor: the hollow rotating platform can flexibly change the size of the interface by customizing the flange and input shaft hole, which is suitable for connecting any brand of servo motor

3. Repeated positioning accuracy: the hollow rotating platform adopts spiral gear deceleration to increase the output torque, and the accuracy grade of some gears reaches grade 2, so that the positioning accuracy of the hollow rotating platform is less than 10 arc seconds. (in order to ensure the accuracy, some spare parts are imported from Japan)

4. Direct connection: the same as divider and DD motor, heavy objects can be directly placed on the platform for transmission.

5. Design: considering the lateral force and other problems during the use of the product, the product adopts “radial axial bearing” in the design, so as to better bear the load during the use process. In order to ensure high precision, some spare parts are imported from Japan.

6. Processing: the hollow rotating platform body is dewaxed and formed, and processed by precision level to ensure the accuracy of each part. The gear adopts the process of grinding after heat treatment, and its surface hardness can reach hrc52. After the product is assembled, another grinding process will be carried out to ensure the parallelism and perpendicularity of each part.

7. Testing: after the assembly of each product, the gear backlash and repeated positioning accuracy will be tested through German henderhan angle analysis to ensure the whole process of a manufacturing to be tested. 

Hollow Indexing Table: The Most Innovative Indexing Method

Introduction
Hollow indexing tables are the latest innovation in indexing methods from Tallman Robotics. This new method is more efficient and versatile than anything else on the market, and it offers a number of advantages for users.
In addition to being more efficient, hollow indexing tables are also more accurate. This is due to the fact that they use a laser to align the indexing arm, which ensures that the arm is always in the correct position.
another advantage of this new technology is that it is significantly quieter than other methods, making it ideal for use in noise-sensitive environments.

How the Hollow Indexing Table Works

Hollow indexing tables work by utilizing a hollow ring arm and a laser-guided alignment system. The arm is mounted onto a stepper motor, which rotates it around its circumference. As the arm rotates, it indexes a row of pins to move the arm to a new location. The laser-guided system that is used in hollow indexing tables is able to detect the exact location of the arm and the pins, ensuring the arm always moves to the right location with precision. The hollow ring arm is connected to several linear actuators, which move the arm back and forth in a precise manner. This allows the arm to accurately index the pins in the row and move to a new position quickly and accurately. The linear actuators also reduce the amount of noise made during the indexing process, ensuring that it is quiet enough for use in noise-sensitive environments.

The Benefits of the Hollow Indexing Table

One of the primary benefits of hollow indexing tables is their increased efficiency and accuracy. This is due to the laser-guided alignment system that is used to keep the arm in the correct position, as well as the linear actuators that allow the arm to move quickly and precisely to its new location. This increases the speed of the indexing process, allowing for faster indexing and increased accuracy. Another benefit of hollow indexing tables is their noise level. As mentioned previously, the linear actuators reduce the noise that is generated by the indexing process, making them ideal for use in noise-sensitive environments. Furthermore, the lack of noise can improve the overall work environment and reduce the potential for distractions.

The Drawbacks of the Hollow Indexing Table

While there are many benefits to using hollow indexing tables, there are also some potential drawbacks. One of the primary drawbacks is the cost of the laser-guided alignment system. While this system is necessary for the accuracy and speed of the indexing process, it can be expensive to purchase and maintain. Additionally, if the laser becomes misaligned, the indexing process can become slow and inaccurate. Another potential drawback of the hollow indexing table is that it requires a significant amount of space. This can be an issue for workplaces with limited floor space or limited storage, as the table itself needs to be large enough to accommodate the arm and all of its components.

Why the Hollow Indexing Table is the Most Innovative Indexing Method

Hollow indexing tables are the most innovative indexing method because of their accuracy and efficiency. By utilizing a laser-guided alignment system, the arm can be precisely positioned in order to index the pins and move to a new location quickly. The linear actuators then enable it to move back and forth precisely, improving speed and accuracy. Additionally, the noise level is much lower than other indexing methods, making it ideal for use in noise-sensitive environments. Furthermore, the cost of the laser-guided system and the space that the table requires can be prohibitive, making it better suited for larger businesses and organizations.

In conclusion,

hollow indexing tables are the most innovative indexing method because they offer accuracy, speed, and a low noise level. Furthermore, they are capable of indexing a large number of pins quickly, reducing the amount of time needed to index a row. While the cost of the system and the space needed for the table can be prohibitive, these drawbacks can be easily offset by the continued benefits that the system offers.
