Product Features
Fixed rotary index table is an intermittent rotary indexing reducer based on cam indexing technology, which belongs to the cam indexer class of reducers. It has the following characteristics.
Fixed indexing angle
The indexing angle of the fixed rotary index table is determined by the profile curve of the cam of its core structure, and the indexing angle is determined by determining the contour curve. Commonly used indexing angles are 45, 60, 90 and 120, and can be customized according to your process needs.
High repeatability accuracy
With a positioning accuracy of up to 15 arc sec, this product is integrated into the equipment to ensure that each product is processed in the same position and ensures consistent product quality.
High rigidity and shock absorption
The Fixed rotary index table uses highly rigid alloy steel to prepare the core components, while the housing is cast from gray cast iron HT250, which is able to absorb vibrations during operation and withstand large radial and axial loads.
Production Process
I believe you are also curious about how the fixed rotary index table is produced, and its production process mainly has six steps, let's understand them one by one.
Customized Design
First, confirm the customer's needs, including the number of stations, indexing angle, load, speed, accuracy, rotation stop time, etc. Based on this data, our engineers perform mechanical calculations to tailor the most suitable cam curve (e.g., corrected sine, trapezoidal, etc.) to optimize dynamic performance and balance speed and shock.
Production Of Core Components
For key components such as globoidal cam, roller gear cam, and turret, alloy steels such as GCr15 and 20CrMnTi are used for CNC machining, and heat treatments such as quenching and tempering and carburizing are used to form a basic contour.
The housing of the fixed rotary index table is made of gray cast iron HT250 produced under the sand casting process and quenched.
Precision Machining
The final shape grinding of the cam line of the heat-treated curved cam is made using a high-precision CNC grinding machine. The raceways of bearing rings are ground using precision internal and external cylindrical grinders, ensuring their profile accuracy and surface finish. The vertical machining center is used to complete the finishing of each datum surface of the index table box to ensure the position accuracy and verticality of the bearing position and mounting surface.
Inspection And Assembly
After completing the cleaning and non-destructive inspection of all parts before assembly to ensure that the parts are fine, the assembly and oil sealing are carried out in the housing, and all parts are in the best fit state by adjusting the meshing gap between the cam and cam roller and the pre-running fit.
Quality Inspection
In order to ensure that the performance and quality of the factory fixed rotary index table meet the requirements, a series of tests are required, including accuracy testing, runout testing, running testing, and tightness testing.
Cleaning, Rust Prevention And Packaging
After the final inspection, the products will be thoroughly cleaned, sprayed with anti-rust oil on the processing surface, and finally wrapped in a dust bag and placed in a custom-sized wooden box to ensure that the product will not be damaged during transportation.

FAQ
If the fixed rotary index table is making abnormal noises in operation, what could be causing it?
The fixed rotary index table usually has several main reasons for abnormal noise during operation: first, insufficient lubrication or incorrect lubricating oil grade; second, internal parts wear due to overload or fatigue; third, the installation foundation is not firm or the horizontality is not up to standard, resulting in slight deformation and deformation of the box; Fourth, the vibration transmitted by the problem of external transmission components (such as timing belts and couplings). It needs to be systematically investigated one by one.
Our existing equipment uses a servo indexing solution, can we replace it with a fixed rotary index table to improve performance?
Absolutely yes, and this is often the result of upgrades that pursue higher speed, higher rigidity, and longer life. When replaced, our engineers assist you in confirming key interface dimensions, load parameters, and indexing angles. Replacing the flexible servo system with a mechanical fixed rotary index table can significantly improve the cycle stability and impact resistance of the equipment under high-speed and heavy load conditions, and reduce long-term maintenance costs.
Fixed rotary index table In addition to high loads, what are the advantages of automated production lines that require continuous operation for a long time?
The advantage of the Fixed rotary index table is that its fully mechanical transmission structure avoids the loss of electronic components, improves the overall service life, and the core components that have been precision-machined and heat-treated wear extremely slowly under oil bath lubrication. It can provide good operational stability.
