Our harmonic reducers, with a custom backlash of ≤5 arc seconds, achieve zero-clearance transmission for precision packaging. To meet the production line upgrade needs of the packaging machinery industries in Turkey and Indonesia, we leverage our ISO 5-grade gear manufacturing, ultra-precision CNC machining (±0.002mm), and large-scale casting capabilities to provide tailored, comprehensive solutions from core components to the overall process.
Products Description
Hollow rotary index tables serve as precision tools in manufacturing and automation, facilitating the accurate positioning of workpieces or tools at varying angles or orientations. Comprising a circular, hollow platform capable of rotation around a central axis, these tables feature a central cutout or hole, allowing objects to pass through seamlessly.
Primarily employed in machining, assembly, and inspection tasks demanding meticulous positioning, these tables streamline the handling of workpieces. They enable operations like drilling, milling, welding, and assembly to be conducted with exactitude at specific angles or orientations.
Hansheng Automation provides HRT-85 series rotary index tables including reduction ratio of 5/10/15/20/25/35/50 and can be adapted to servo motors of 200 to 400W and 57 stepper motors.
Features and Advantages
High-Precision Positioning
The core advantage of the hollow rotary indexing table lies in its high-precision angular positioning capability (standard accuracy ≤ 15 arc sec, custom accuracy ≤ 10 arc sec). This ensures extremely tight positional tolerances between multiple holes and slots in mechanical parts machining.
Hollow Structure
The table features a central hollow design, creating a through-hole. This feature makes it easily adaptable to applications requiring wire threading, pipe routing, or the passage of long workpieces.
Efficient and Simplified
The hollow rotary indexing table can complete multi-faceted and multi-angle machining in a single clamping operation, significantly reducing clamping times and positioning errors. Furthermore, it is compatible with automated control systems and seamlessly integrates with robots, machine tools, and other equipment, achieving automated and continuous production processes.
HRT-85 Series Product Details
A Variety of Gear Ratio Options
A variety of gear ratios, including 5/10/15/20/25/35/50, are available to meet the speed and torque requirements of different scenarios:
Low gear ratios (e.g., 5 and 10): High output torque, suitable for applications with heavy loads but high speed requirements (e.g., rapid indexing of heavy parts);
High gear ratios (e.g., 35 and 50): Higher indexing accuracy, suitable for precision operations requiring strict angle control (e.g., optical component assembly and micro-parts inspection).
Flexible Motor Compatibility
Servo motors (200-400W): Fast response speed and high positioning accuracy, suitable for automated production lines requiring high dynamic performance, enabling rapid start and stop and precise angular adjustment;
57° stepper motors: Low cost and simple control, suitable for small and medium-sized businesses with limited budgets and low speed requirements, meeting stable indexing needs.

FAQ
Q: What is the center hole size of the HRT-85 series hollow rotary indexing table?
A: The center hole size of the HRT-85 series varies slightly depending on the specific model. It is primarily suitable for small and medium-sized workpieces or pipeline routing. For detailed specifications, please contact the manufacturer for a technical manual.
Q: How do I choose the appropriate reduction ratio?
A: This should be determined based on the load weight, required speed, and accuracy requirements. For heavy loads and high speeds, a low reduction ratio (such as 5 or 10) can be selected; for high accuracy requirements and slower speeds, a high reduction ratio (such as 35 or 50) can be selected.
Q: What are the main differences between stepper motor and servo motor compatible models?
A: Stepper motor compatible models (ST series) are lower cost and suitable for static or low-speed indexing applications. Servo motor compatible models (SV series) offer faster response and higher dynamic positioning accuracy, making them suitable for high-speed, high-frequency indexing automated production lines.
Q: Can this worktable be used in corrosive environments?
A: Some models (such as the HRT85JS-L1 series) feature special surface treatment and sealing designs to withstand mildly corrosive environments, but more corrosive environments require customized protection solutions.
Q: What precautions should be taken during installation?
A: The workbench and mounting surface must be level to avoid positioning errors caused by tilt. Also, when routing piping through the center hole, sufficient space must be left to prevent friction and interference during rotation.
