Hollow Bore Rotary Table

The turntable of Hollow Bore Rotary Table adopts a hollow structure design, which has significant advantages. On the one hand, it facilitates the installation of gas pipes and wires in the fixture, effectively avoiding winding of the circuit, making the overall layout more concise and orderly, and reducing the risk of faults caused by circuit problems; On the other hand, the motor is connected to the side, greatly simplifying the installation process, reducing installation space requirements, and facilitating equipment integration and maintenance.

FAQ:

1. Is the response speed of the hollow rotating platform related to the type of motor?
      Yes. Servo motors provide the fastest response due to high torque-to-inertia ratio. Stepper motors respond slower and risk missing steps. Induction motors have sluggish response. Direct drive torque motors offer excellent response with precise control. Choose a servo motor for dynamic applications requiring quick starts and stops.

2. How much impact does high-speed start stop have on the transmission mechanism?
     High-speed start-stop causes significant impact. It generates shock loads that accelerate bearing and gear wear. Repeated cycles create fatigue cracks, increase backlash, and may damage cam profiles. The transmission mechanism loses precision over time. Use soft-start acceleration ramps and reduce load inertia to minimize this damage.

3. How to calculate the maximum allowable speed of a hollow rotating platform?
    Use this formula: max speed (rpm) = (safe peripheral speed of bearing rollers × 1000) / (π × bearing pitch diameter in mm). Safe peripheral speed typically ranges 500–1500 m/min for crossed roller bearings. Also check the manufacturer's input shaft speed limit. Derate the speed for heavy loads or poor lubrication.

4. What is the accuracy of speed regulation?
    Open-loop systems achieve ±0.1% to ±1% speed regulation. Closed-loop servo drives with encoder feedback reach ±0.01% or better. Factors affecting accuracy include load variation, motor quality, and control algorithm. For most automation tasks, ±0.5% suffices. High-precision applications require closed-loop control.

5. What are the speed requirements for hollow rotating platforms in different industries?
    Semiconductor equipment: 200–500 rpm with high precision. Packaging machinery: 100–300 rpm moderate speed. Robotics: 50–200 rpm for smooth motion. Heavy machinery: 10–100 rpm with high torque. Medical devices: 50–150 rpm requiring low noise and smooth operation. Always match speed to your specific application needs.
